<p class="firstline">Leases tasks from a pull queue for lease_duration. This method is invoked by the worker to obtain a lease. The worker must acknowledge the task via AcknowledgeTask after they have performed the work associated with the task. The payload is intended to store data that the worker needs to perform the work associated with the task. To return the payloads in the response, set response_view to FULL. A maximum of 10 qps of LeaseTasks requests are allowed per queue. RESOURCE_EXHAUSTED is returned when this limit is exceeded.

This command is meant to be used for manual debugging. For example, RunTask can be used to retry a failed task after a fix has been made or to manually force a task to be dispatched now. The dispatched task is returned. That is, the task that is returned contains the status after the task is dispatched but before the task is received by its target. If Cloud Tasks receives a successful response from the task's target, then the task will be deleted; otherwise the task's schedule_time will be reset to the time that RunTask was called plus the retry delay specified in the queue's RetryConfig. RunTask returns NOT_FOUND when it is called on a task that has already succeeded or permanently failed. RunTask cannot be called on a pull task.</p>
<h3>Method Details</h3>
<div class="method">
    <code class="details" id="acknowledge">acknowledge(name, body=None, x__xgafv=None)</code>
  <pre>Acknowledges a pull task. The worker, that is, the entity that leased this task must call this method to indicate that the work associated with the task has finished. The worker must acknowledge a task within the lease_duration or the lease will expire and the task will become available to be leased again. After the task is acknowledged, it will not be returned by a later LeaseTasks, GetTask, or ListTasks.

Args:
  name: string, Required. The task name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID` (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for acknowledging a task using AcknowledgeTask.
  &quot;scheduleTime&quot;: &quot;A String&quot;, # Required. The task&#x27;s current schedule time, available in the schedule_time returned by LeaseTasks response or RenewLease response. This restriction is to ensure that your worker currently holds the lease.
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); }
}</pre>
</div>

<div class="method">
    <code class="details" id="buffer">buffer(queue, taskId, body=None, x__xgafv=None)</code>
  <pre>Creates and buffers a new task without the need to explicitly define a Task message. The queue must have HTTP target. To create the task with a custom ID, use the following format and set TASK_ID to your desired ID: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID:buffer To create the task with an automatically generated ID, use the following format: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks:buffer.

Args:
  queue: string, Required. The parent queue name. For example: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID` The queue must already exist. (required)
  taskId: string, Optional. Task ID for the task being created. If not provided, a random task ID is assigned to the task. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for BufferTask.
  &quot;body&quot;: { # Message that represents an arbitrary HTTP body. It should only be used for payload formats that can&#x27;t be represented as JSON, such as raw binary or an HTML page. This message can be used both in streaming and non-streaming API methods in the request as well as the response. It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body. Example: message GetResourceRequest { // A unique request id. string request_id = 1; // The raw HTTP body is bound to this field. google.api.HttpBody http_body = 2; } service ResourceService { rpc GetResource(GetResourceRequest) returns (google.api.HttpBody); rpc UpdateResource(google.api.HttpBody) returns (google.protobuf.Empty); } Example with streaming methods: service CaldavService { rpc GetCalendar(stream google.api.HttpBody) returns (stream google.api.HttpBody); rpc UpdateCalendar(stream google.api.HttpBody) returns (stream google.api.HttpBody); } Use of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged. # Optional. Body of the HTTP request. The body can take any generic value. The value is written to the HttpRequest of the [Task].
    &quot;contentType&quot;: &quot;A String&quot;, # The HTTP Content-Type header value specifying the content type of the body.
    &quot;data&quot;: &quot;A String&quot;, # The HTTP request/response body as raw binary.
    &quot;extensions&quot;: [ # Application specific response metadata. Must be set in the first response for streaming APIs.
      {
        &quot;a_key&quot;: &quot;&quot;, # Properties of the object. Contains field @type with type URL.
      },
    ],
  },
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # Response message for BufferTask.
  &quot;task&quot;: { # A unit of scheduled work. # The created task.
    &quot;appEngineHttpRequest&quot;: { # App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. This proto can only be used for tasks in a queue which has app_engine_http_target set. Using AppEngineHttpRequest requires [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control) Google IAM permission for the project and the following scope: `https://www.googleapis.com/auth/cloud-platform` The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_url Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # App Engine HTTP request that is sent to the task&#x27;s target. Can be set only if app_engine_http_target is set on the queue. An App Engine task is a task that has AppEngineHttpRequest set.
      &quot;appEngineRouting&quot;: { # App Engine Routing. Defines routing characteristics specific to App Engine - service, version, and instance. For more information about services, versions, and instances see [An Overview of App Engine](https://cloud.google.com/appengine/docs/python/an-overview-of-app-engine), [Microservices Architecture on Google App Engine](https://cloud.google.com/appengine/docs/python/microservices-on-app-engine), [App Engine Standard request routing](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed), and [App Engine Flex request routing](https://cloud.google.com/appengine/docs/flexible/python/how-requests-are-routed). # Task-level setting for App Engine routing. If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing.
        &quot;host&quot;: &quot;A String&quot;, # Output only. The host that the task is sent to. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed). The host is constructed as: * `host = [application_domain_name]` `| [service] + &#x27;.&#x27; + [application_domain_name]` `| [version] + &#x27;.&#x27; + [application_domain_name]` `| [version_dot_service]+ &#x27;.&#x27; + [application_domain_name]` `| [instance] + &#x27;.&#x27; + [application_domain_name]` `| [instance_dot_service] + &#x27;.&#x27; + [application_domain_name]` `| [instance_dot_version] + &#x27;.&#x27; + [application_domain_name]` `| [instance_dot_version_dot_service] + &#x27;.&#x27; + [application_domain_name]` * `application_domain_name` = The domain name of the app, for example .appspot.com, which is associated with the queue&#x27;s project ID. Some tasks which were created using the App Engine SDK use a custom domain name. * `service =` service * `version =` version * `version_dot_service =` version `+ &#x27;.&#x27; +` service * `instance =` instance * `instance_dot_service =` instance `+ &#x27;.&#x27; +` service * `instance_dot_version =` instance `+ &#x27;.&#x27; +` version * `instance_dot_version_dot_service =` instance `+ &#x27;.&#x27; +` version `+ &#x27;.&#x27; +` service If service is empty, then the task will be sent to the service which is the default service when the task is attempted. If version is empty, then the task will be sent to the version which is the default version when the task is attempted. If instance is empty, then the task will be sent to an instance which is available when the task is attempted. If service, version, or instance is invalid, then the task will be sent to the default version of the default service when the task is attempted.
        &quot;instance&quot;: &quot;A String&quot;, # App instance. By default, the task is sent to an instance which is available when the task is attempted. Requests can only be sent to a specific instance if [manual scaling is used in App Engine Standard](https://cloud.google.com/appengine/docs/python/an-overview-of-app-engine?hl=en_US#scaling_types_and_instance_classes). App Engine Flex does not support instances. For more information, see [App Engine Standard request routing](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and [App Engine Flex request routing](https://cloud.google.com/appengine/docs/flexible/python/how-requests-are-routed).
        &quot;service&quot;: &quot;A String&quot;, # App service. By default, the task is sent to the service which is the default service when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If host is not parsable, then service, version, and instance are the empty string.
        &quot;version&quot;: &quot;A String&quot;, # App version. By default, the task is sent to the version which is the default version when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If host is not parsable, then service, version, and instance are the empty string.

      &quot;headers&quot;: { # HTTP request headers. This map contains the header field names and values. Headers can be set when the task is created. Repeated headers are not supported but a header value can contain commas. Cloud Tasks sets some headers to default values: * `User-Agent`: By default, this header is `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;`. This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a payload, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.

<div class="method">
    <code class="details" id="cancelLease">cancelLease(name, body=None, x__xgafv=None)</code>
  <pre>Cancel a pull task&#x27;s lease. The worker can use this method to cancel a task&#x27;s lease by setting its schedule_time to now. This will make the task available to be leased to the next caller of LeaseTasks.

Args:
  name: string, Required. The task name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID` (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for canceling a lease using CancelLease.
  &quot;responseView&quot;: &quot;A String&quot;, # The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Task resource.
  &quot;scheduleTime&quot;: &quot;A String&quot;, # Required. The task&#x27;s current schedule time, available in the schedule_time returned by LeaseTasks response or RenewLease response. This restriction is to ensure that your worker currently holds the lease.
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # A unit of scheduled work.
  &quot;appEngineHttpRequest&quot;: { # App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. This proto can only be used for tasks in a queue which has app_engine_http_target set. Using AppEngineHttpRequest requires [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control) Google IAM permission for the project and the following scope: `https://www.googleapis.com/auth/cloud-platform` The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_url Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # App Engine HTTP request that is sent to the task&#x27;s target. Can be set only if app_engine_http_target is set on the queue. An App Engine task is a task that has AppEngineHttpRequest set.
    &quot;appEngineRouting&quot;: { # App Engine Routing. Defines routing characteristics specific to App Engine - service, version, and instance.

Some tasks which were created using the App Engine SDK use a custom domain name. * `service =` service * `version =` version * `version_dot_service =` version `+ &#x27;.&#x27; +` service * `instance =` instance * `instance_dot_service =` instance `+ &#x27;.&#x27; +` service * `instance_dot_version =` instance `+ &#x27;.&#x27; +` version * `instance_dot_version_dot_service =` instance `+ &#x27;.&#x27; +` version `+ &#x27;.&#x27; +` service If service is empty, then the task will be sent to the service which is the default service when the task is attempted. If version is empty, then the task will be sent to the version which is the default version when the task is attempted. If instance is empty, then the task will be sent to an instance which is available when the task is attempted. If service, version, or instance is invalid, then the task will be sent to the default version of the default service when the task is attempted.
      &quot;instance&quot;: &quot;A String&quot;, # App instance. By default, the task is sent to an instance which is available when the task is attempted. Requests can only be sent to a specific instance if [manual scaling is used in App Engine Standard](https://cloud.google.com/appengine/docs/python/an-overview-of-app-engine?hl=en_US#scaling_types_and_instance_classes). App Engine Flex does not support instances.

      &quot;service&quot;: &quot;A String&quot;, # App service. By default, the task is sent to the service which is the default service when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If host is not parsable, then service, version, and instance are the empty string.
      &quot;version&quot;: &quot;A String&quot;, # App version. By default, the task is sent to the version which is the default version when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance.

    &quot;headers&quot;: { # HTTP request headers. This map contains the header field names and values. Headers can be set when the task is created. Repeated headers are not supported but a header value can contain commas. Cloud Tasks sets some headers to default values: * `User-Agent`: By default, this header is `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;`. This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a payload, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.

  <pre>Creates a task and adds it to a queue. Tasks cannot be updated after creation; there is no UpdateTask command. * For App Engine queues, the maximum task size is 100KB. * For pull queues, the maximum task size is 1MB.

Args:
  parent: string, Required. The queue name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID` The queue must already exist. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for CreateTask.
  &quot;responseView&quot;: &quot;A String&quot;, # The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Task resource.
  &quot;task&quot;: { # A unit of scheduled work. # Required. The task to add. Task names have the following format: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID`. The user can optionally specify a task name. If a name is not specified then the system will generate a random unique task id, which will be set in the task returned in the response. If schedule_time is not set or is in the past then Cloud Tasks will set it to the current time. Task De-duplication: Explicitly specifying a task ID enables task de-duplication. If a task&#x27;s ID is identical to that of an existing task or a task that was deleted or completed recently then the call will fail with ALREADY_EXISTS. The IDs of deleted tasks are not immediately available for reuse. It can take up to 4 hours (or 9 days if the task&#x27;s queue was created using a queue.yaml or queue.xml) for the task ID to be released and made available again. Because there is an extra lookup cost to identify duplicate task names, these CreateTask calls have significantly increased latency. Using hashed strings for the task id or for the prefix of the task id is recommended. Choosing task ids that are sequential or have sequential prefixes, for example using a timestamp, causes an increase in latency and error rates in all task commands. The infrastructure relies on an approximately uniform distribution of task ids to store and serve tasks efficiently.
    &quot;appEngineHttpRequest&quot;: { # App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. This proto can only be used for tasks in a queue which has app_engine_http_target set. Using AppEngineHttpRequest requires [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control) Google IAM permission for the project and the following scope: `https://www.googleapis.com/auth/cloud-platform` The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_url Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # App Engine HTTP request that is sent to the task&#x27;s target. Can be set only if app_engine_http_target is set on the queue. An App Engine task is a task that has AppEngineHttpRequest set.

If version is empty, then the task will be sent to the version which is the default version when the task is attempted. If instance is empty, then the task will be sent to an instance which is available when the task is attempted. If service, version, or instance is invalid, then the task will be sent to the default version of the default service when the task is attempted.
        &quot;instance&quot;: &quot;A String&quot;, # App instance. By default, the task is sent to an instance which is available when the task is attempted.

For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If host is not parsable, then service, version, and instance are the empty string.

      &quot;headers&quot;: { # HTTP request headers. This map contains the header field names and values. Headers can be set when the task is created. Repeated headers are not supported but a header value can contain commas. Cloud Tasks sets some headers to default values: * `User-Agent`: By default, this header is `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;`. This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a payload, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.

This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a payload, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.

  <pre>Deletes a task. A task can be deleted if it is scheduled or dispatched. A task cannot be deleted if it has completed successfully or permanently failed.

Args:
  name: string, Required. The task name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID` (required)
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); }

  responseView: string, The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Task resource.
    Allowed values
      VIEW_UNSPECIFIED - Unspecified. Defaults to BASIC.
      BASIC - The basic view omits fields which can be large or can contain sensitive data. This view does not include the (payload in AppEngineHttpRequest and payload in PullMessage). These payloads are desirable to return only when needed, because they can be large and because of the sensitivity of the data that you choose to store in it.
      FULL - All information is returned. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Queue resource.

For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_url Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # App Engine HTTP request that is sent to the task&#x27;s target.

Cloud Tasks sets some headers to default values: * `User-Agent`: By default, this header is `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;`. This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a payload, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.

<div class="method">
    <code class="details" id="lease">lease(parent, body=None, x__xgafv=None)</code>
  <pre>Leases tasks from a pull queue for lease_duration. This method is invoked by the worker to obtain a lease. The worker must acknowledge the task via AcknowledgeTask after they have performed the work associated with the task. The payload is intended to store data that the worker needs to perform the work associated with the task. To return the payloads in the response, set response_view to FULL. A maximum of 10 qps of LeaseTasks requests are allowed per queue. RESOURCE_EXHAUSTED is returned when this limit is exceeded. RESOURCE_EXHAUSTED is also returned when max_tasks_dispatched_per_second is exceeded.

Args:
  parent: string, Required. The queue name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID` (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for leasing tasks using LeaseTasks.
  &quot;filter&quot;: &quot;A String&quot;, # `filter` can be used to specify a subset of tasks to lease. When `filter` is set to `tag=` then the response will contain only tasks whose tag is equal to ``. `` must be less than 500 characters. When `filter` is set to `tag_function=oldest_tag()`, only tasks which have the same tag as the task with the oldest schedule_time will be returned. Grammar Syntax: * `filter = &quot;tag=&quot; tag | &quot;tag_function=&quot; function` * `tag = string` * `function = &quot;oldest_tag()&quot;` The `oldest_tag()` function returns tasks which have the same tag as the oldest task (ordered by schedule time). SDK compatibility: Although the SDK allows tags to be either string or [bytes](https://cloud.google.com/appengine/docs/standard/java/javadoc/com/google/appengine/api/taskqueue/TaskOptions.html#tag-byte:A-), only UTF-8 encoded tags can be used in Cloud Tasks. Tag which aren&#x27;t UTF-8 encoded can&#x27;t be used in the filter and the task&#x27;s tag will be displayed as empty in Cloud Tasks.
  &quot;leaseDuration&quot;: &quot;A String&quot;, # Required. The duration of the lease. Each task returned in the response will have its schedule_time set to the current time plus the `lease_duration`. The task is leased until its schedule_time; thus, the task will not be returned to another LeaseTasks call before its schedule_time. After the worker has successfully finished the work associated with the task, the worker must call via AcknowledgeTask before the schedule_time. Otherwise the task will be returned to a later LeaseTasks call so that another worker can retry it. The maximum lease duration is 1 week. `lease_duration` will be truncated to the nearest second.
  &quot;maxTasks&quot;: 42, # The maximum number of tasks to lease. The system will make a best effort to return as close to as `max_tasks` as possible. The largest that `max_tasks` can be is 1000. The maximum total size of a lease tasks response is 32 MB. If the sum of all task sizes requested reaches this limit, fewer tasks than requested are returned.
  &quot;responseView&quot;: &quot;A String&quot;, # The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Task resource.
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # Response message for leasing tasks using LeaseTasks.
  &quot;tasks&quot;: [ # The leased tasks.
    { # A unit of scheduled work.
      &quot;appEngineHttpRequest&quot;: { # App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. This proto can only be used for tasks in a queue which has app_engine_http_target set. Using AppEngineHttpRequest requires [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control) Google IAM permission for the project and the following scope: `https://www.googleapis.com/auth/cloud-platform` The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_url Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # App Engine HTTP request that is sent to the task&#x27;s target. Can be set only if app_engine_http_target is set on the queue. An App Engine task is a task that has AppEngineHttpRequest set.

Some tasks which were created using the App Engine SDK use a custom domain name. * `service =` service * `version =` version * `version_dot_service =` version `+ &#x27;.&#x27; +` service * `instance =` instance * `instance_dot_service =` instance `+ &#x27;.&#x27; +` service * `instance_dot_version =` instance `+ &#x27;.&#x27; +` version * `instance_dot_version_dot_service =` instance `+ &#x27;.&#x27; +` version `+ &#x27;.&#x27; +` service If service is empty, then the task will be sent to the service which is the default service when the task is attempted. If version is empty, then the task will be sent to the version which is the default version when the task is attempted. If instance is empty, then the task will be sent to an instance which is available when the task is attempted. If service, version, or instance is invalid, then the task will be sent to the default version of the default service when the task is attempted.
          &quot;instance&quot;: &quot;A String&quot;, # App instance. By default, the task is sent to an instance which is available when the task is attempted.

This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a payload, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.

<div class="method">
    <code class="details" id="list">list(parent, pageSize=None, pageToken=None, responseView=None, x__xgafv=None)</code>
  <pre>Lists the tasks in a queue. By default, only the BASIC view is retrieved due to performance considerations; response_view controls the subset of information which is returned. The tasks may be returned in any order. The ordering may change at any time.

Args:
  parent: string, Required. The queue name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID` (required)
  pageSize: integer, Maximum page size. Fewer tasks than requested might be returned, even if more tasks exist; use next_page_token in the response to determine if more tasks exist. The maximum page size is 1000. If unspecified, the page size will be the maximum.
  pageToken: string, A token identifying the page of results to return. To request the first page results, page_token must be empty. To request the next page of results, page_token must be the value of next_page_token returned from the previous call to ListTasks method. The page token is valid for only 2 hours.
  responseView: string, The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Task resource.
    Allowed values
      VIEW_UNSPECIFIED - Unspecified. Defaults to BASIC.
      BASIC - The basic view omits fields which can be large or can contain sensitive data. This view does not include the (payload in AppEngineHttpRequest and payload in PullMessage). These payloads are desirable to return only when needed, because they can be large and because of the sensitivity of the data that you choose to store in it.
      FULL - All information is returned. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Queue resource.
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # Response message for listing tasks using ListTasks.
  &quot;nextPageToken&quot;: &quot;A String&quot;, # A token to retrieve next page of results. To return the next page of results, call ListTasks with this value as the page_token. If the next_page_token is empty, there are no more results.
  &quot;tasks&quot;: [ # The list of tasks.
    { # A unit of scheduled work.
      &quot;appEngineHttpRequest&quot;: { # App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. This proto can only be used for tasks in a queue which has app_engine_http_target set. Using AppEngineHttpRequest requires [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control) Google IAM permission for the project and the following scope: `https://www.googleapis.com/auth/cloud-platform` The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_url Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # App Engine HTTP request that is sent to the task&#x27;s target. Can be set only if app_engine_http_target is set on the queue. An App Engine task is a task that has AppEngineHttpRequest set.

Some tasks which were created using the App Engine SDK use a custom domain name. * `service =` service * `version =` version * `version_dot_service =` version `+ &#x27;.&#x27; +` service * `instance =` instance * `instance_dot_service =` instance `+ &#x27;.&#x27; +` service * `instance_dot_version =` instance `+ &#x27;.&#x27; +` version * `instance_dot_version_dot_service =` instance `+ &#x27;.&#x27; +` version `+ &#x27;.&#x27; +` service If service is empty, then the task will be sent to the service which is the default service when the task is attempted. If version is empty, then the task will be sent to the version which is the default version when the task is attempted. If instance is empty, then the task will be sent to an instance which is available when the task is attempted. If service, version, or instance is invalid, then the task will be sent to the default version of the default service when the task is attempted.
          &quot;instance&quot;: &quot;A String&quot;, # App instance. By default, the task is sent to an instance which is available when the task is attempted.

          &quot;service&quot;: &quot;A String&quot;, # App service. By default, the task is sent to the service which is the default service when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If host is not parsable, then service, version, and instance are the empty string.
          &quot;version&quot;: &quot;A String&quot;, # App version. By default, the task is sent to the version which is the default version when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance.

        &quot;headers&quot;: { # HTTP request headers. This map contains the header field names and values. Headers can be set when the task is created. Repeated headers are not supported but a header value can contain commas. Cloud Tasks sets some headers to default values: * `User-Agent`: By default, this header is `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;`. This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a payload, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.

<div class="method">
    <code class="details" id="renewLease">renewLease(name, body=None, x__xgafv=None)</code>
  <pre>Renew the current lease of a pull task. The worker can use this method to extend the lease by a new duration, starting from now. The new task lease will be returned in the task&#x27;s schedule_time.

Args:
  name: string, Required. The task name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID` (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for renewing a lease using RenewLease.

  &quot;appEngineHttpRequest&quot;: { # App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. This proto can only be used for tasks in a queue which has app_engine_http_target set. Using AppEngineHttpRequest requires [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control) Google IAM permission for the project and the following scope: `https://www.googleapis.com/auth/cloud-platform` The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_url Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # App Engine HTTP request that is sent to the task&#x27;s target. Can be set only if app_engine_http_target is set on the queue. An App Engine task is a task that has AppEngineHttpRequest set.

If version is empty, then the task will be sent to the version which is the default version when the task is attempted. If instance is empty, then the task will be sent to an instance which is available when the task is attempted. If service, version, or instance is invalid, then the task will be sent to the default version of the default service when the task is attempted.

This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a payload, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response.

<div class="method">
    <code class="details" id="run">run(name, body=None, x__xgafv=None)</code>
  <pre>Forces a task to run now. When this method is called, Cloud Tasks will dispatch the task, even if the task is already running, the queue has reached its RateLimits or is PAUSED. This command is meant to be used for manual debugging. For example, RunTask can be used to retry a failed task after a fix has been made or to manually force a task to be dispatched now. The dispatched task is returned. That is, the task that is returned contains the status after the task is dispatched but before the task is received by its target. If Cloud Tasks receives a successful response from the task&#x27;s target, then the task will be deleted; otherwise the task&#x27;s schedule_time will be reset to the time that RunTask was called plus the retry delay specified in the queue&#x27;s RetryConfig. RunTask returns NOT_FOUND when it is called on a task that has already succeeded or permanently failed. RunTask cannot be called on a pull task.

Args:
  name: string, Required. The task name. For example: `projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID` (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for forcing a task to run now using RunTask.
  &quot;responseView&quot;: &quot;A String&quot;, # The response_view specifies which subset of the Task will be returned. By default response_view is BASIC; not all information is retrieved by default because some data, such as payloads, might be desirable to return only when needed because of its large size or because of the sensitivity of data that it contains. Authorization for FULL requires `cloudtasks.tasks.fullView` [Google IAM](https://cloud.google.com/iam/) permission on the Task resource.
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # A unit of scheduled work.
  &quot;appEngineHttpRequest&quot;: { # App Engine HTTP request. The message defines the HTTP request that is sent to an App Engine app when the task is dispatched. This proto can only be used for tasks in a queue which has app_engine_http_target set. Using AppEngineHttpRequest requires [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control) Google IAM permission for the project and the following scope: `https://www.googleapis.com/auth/cloud-platform` The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and how routing is affected by [dispatch files](https://cloud.google.com/appengine/docs/python/config/dispatchref). Traffic is encrypted during transport and never leaves Google datacenters. Because this traffic is carried over a communication mechanism internal to Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS). The request to the handler, however, will appear to have used the HTTP protocol. The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level: * If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing. The `url` that the task will be sent to is: * `url =` host `+` relative_url Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with [`login: admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref). Because tasks are not run as any user, they cannot be dispatched to URIs restricted with [`login: required`](https://cloud.google.com/appengine/docs/standard/python/config/appref) Task dispatches also do not follow redirects. The task attempt has succeeded if the app&#x27;s request handler returns an HTTP response code in the range [`200` - `299`]. The task attempt has failed if the app&#x27;s handler returns a non-2xx response code or Cloud Tasks does not receive response before the deadline. Failed tasks will be retried according to the retry configuration. `503` (Service Unavailable) is considered an App Engine system error instead of an application error and will cause Cloud Tasks&#x27; traffic congestion control to temporarily throttle the queue&#x27;s dispatches. Unlike other types of task targets, a `429` (Too Many Requests) response from an app handler does not cause traffic congestion control to throttle the queue. # App Engine HTTP request that is sent to the task&#x27;s target. Can be set only if app_engine_http_target is set on the queue. An App Engine task is a task that has AppEngineHttpRequest set.
    &quot;appEngineRouting&quot;: { # App Engine Routing. Defines routing characteristics specific to App Engine - service, version, and instance. For more information about services, versions, and instances see [An Overview of App Engine](https://cloud.google.com/appengine/docs/python/an-overview-of-app-engine), [Microservices Architecture on Google App Engine](https://cloud.google.com/appengine/docs/python/microservices-on-app-engine), [App Engine Standard request routing](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed), and [App Engine Flex request routing](https://cloud.google.com/appengine/docs/flexible/python/how-requests-are-routed). # Task-level setting for App Engine routing. If set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing.
      &quot;host&quot;: &quot;A String&quot;, # Output only. The host that the task is sent to. For more information, see [How Requests are Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed). The host is constructed as: * `host = [application_domain_name]` `| [service] + &#x27;.&#x27; + [application_domain_name]` `| [version] + &#x27;.&#x27; + [application_domain_name]` `| [version_dot_service]+ &#x27;.&#x27; + [application_domain_name]` `| [instance] + &#x27;.&#x27; + [application_domain_name]` `| [instance_dot_service] + &#x27;.&#x27; + [application_domain_name]` `| [instance_dot_version] + &#x27;.&#x27; + [application_domain_name]` `| [instance_dot_version_dot_service] + &#x27;.&#x27; + [application_domain_name]` * `application_domain_name` = The domain name of the app, for example .appspot.com, which is associated with the queue&#x27;s project ID. Some tasks which were created using the App Engine SDK use a custom domain name. * `service =` service * `version =` version * `version_dot_service =` version `+ &#x27;.&#x27; +` service * `instance =` instance * `instance_dot_service =` instance `+ &#x27;.&#x27; +` service * `instance_dot_version =` instance `+ &#x27;.&#x27; +` version * `instance_dot_version_dot_service =` instance `+ &#x27;.&#x27; +` version `+ &#x27;.&#x27; +` service If service is empty, then the task will be sent to the service which is the default service when the task is attempted. If version is empty, then the task will be sent to the version which is the default version when the task is attempted. If instance is empty, then the task will be sent to an instance which is available when the task is attempted. If service, version, or instance is invalid, then the task will be sent to the default version of the default service when the task is attempted.
      &quot;instance&quot;: &quot;A String&quot;, # App instance. By default, the task is sent to an instance which is available when the task is attempted. Requests can only be sent to a specific instance if [manual scaling is used in App Engine Standard](https://cloud.google.com/appengine/docs/python/an-overview-of-app-engine?hl=en_US#scaling_types_and_instance_classes). App Engine Flex does not support instances. For more information, see [App Engine Standard request routing](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed) and [App Engine Flex request routing](https://cloud.google.com/appengine/docs/flexible/python/how-requests-are-routed).
      &quot;service&quot;: &quot;A String&quot;, # App service. By default, the task is sent to the service which is the default service when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks. If host is not parsable, then service, version, and instance are the empty string.
      &quot;version&quot;: &quot;A String&quot;, # App version. By default, the task is sent to the version which is the default version when the task is attempted. For some queues or tasks which were created using the App Engine Task Queue API, host is not parsable into service, version, and instance. For example, some tasks which were created using the App Engine SDK use a custom domain name; custom domains are not parsed by Cloud Tasks.

    &quot;headers&quot;: { # HTTP request headers. This map contains the header field names and values. Headers can be set when the task is created. Repeated headers are not supported but a header value can contain commas. Cloud Tasks sets some headers to default values: * `User-Agent`: By default, this header is `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;`. This header can be modified, but Cloud Tasks will append `&quot;AppEngine-Google; (+http://code.google.com/appengine)&quot;` to the modified `User-Agent`. If the task has a payload, Cloud Tasks sets the following headers: * `Content-Type`: By default, the `Content-Type` header is set to `&quot;application/octet-stream&quot;`. The default can be overridden by explicitly setting `Content-Type` to a particular media type when the task is created. For example, `Content-Type` can be set to `&quot;application/json&quot;`. * `Content-Length`: This is computed by Cloud Tasks. This value is output only. It cannot be changed. The headers below cannot be set or overridden: * `Host` * `X-Google-*` * `X-AppEngine-*` In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see [request headers](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers). These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response. Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.
