// Retrieves all the metadata from an object without returning the object itself.
// This operation is useful if you're interested only in an object's metadata.
//
// GetObjectAttributes combines the functionality of HeadObject and ListParts . All
// of the data returned with each of those individual calls can be returned with a
// single call to GetObjectAttributes .
//
// Directory buckets - For directory buckets, you must make requests for this API
// operation to the Zonal endpoint. These endpoints support virtual-hosted-style
// requests in the format
// https://bucket_name.s3express-az_id.region.amazonaws.com/key-name . Path-style
// requests are not supported. For more information, see [Regional and Zonal endpoints]in the Amazon S3 User
// Guide.
//
// Permissions
//
//   - General purpose bucket permissions - To use GetObjectAttributes , you must
//     have READ access to the object. The permissions that you need to use this
//     operation with depend on whether the bucket is versioned. If the bucket is
//     versioned, you need both the s3:GetObjectVersion and
//     s3:GetObjectVersionAttributes permissions for this operation. If the bucket is
//     not versioned, you need the s3:GetObject and s3:GetObjectAttributes
//     permissions. For more information, see [Specifying Permissions in a Policy]in the Amazon S3 User Guide. If the
//     object that you request does not exist, the error Amazon S3 returns depends on
//     whether you also have the s3:ListBucket permission.
//
//   - If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an
//     HTTP status code 404 Not Found ("no such key") error.
//
//   - If you don't have the s3:ListBucket permission, Amazon S3 returns an HTTP
//     status code 403 Forbidden ("access denied") error.
//
//   - Directory bucket permissions - To grant access to this API operation on a
//     directory bucket, we recommend that you use the [CreateSession]CreateSession API operation
//     for session-based authorization. Specifically, you grant the
//     s3express:CreateSession permission to the directory bucket in a bucket policy
//     or an IAM identity-based policy. Then, you make the CreateSession API call on
//     the bucket to obtain a session token. With the session token in your request
//     header, you can make API requests to this operation. After the session token
//     expires, you make another CreateSession API call to generate a new session
//     token for use. Amazon Web Services CLI or SDKs create session and refresh the
//     session token automatically to avoid service interruptions when a session
//     expires. For more information about authorization, see [CreateSession]CreateSession .
//
// Encryption Encryption request headers, like x-amz-server-side-encryption ,
// should not be sent for HEAD requests if your object uses server-side encryption
// with Key Management Service (KMS) keys (SSE-KMS), dual-layer server-side
// encryption with Amazon Web Services KMS keys (DSSE-KMS), or server-side
// encryption with Amazon S3 managed encryption keys (SSE-S3). The
// x-amz-server-side-encryption header is used when you PUT an object to S3 and
// want to specify the encryption method. If you include this header in a GET
// request for an object that uses these types of keys, you’ll get an HTTP 400 Bad
// Request error. It's because the encryption method can't be changed when you
// retrieve the object.
//
// If you encrypt an object by using server-side encryption with customer-provided
// encryption keys (SSE-C) when you store the object in Amazon S3, then when you
// retrieve the metadata from the object, you must use the following headers to
// provide the encryption key for the server to be able to retrieve the object's
// metadata. The headers are:
//
//   - x-amz-server-side-encryption-customer-algorithm
//
//   - x-amz-server-side-encryption-customer-key
//
//   - x-amz-server-side-encryption-customer-key-MD5
//
// For more information about SSE-C, see [Server-Side Encryption (Using Customer-Provided Encryption Keys)] in the Amazon S3 User Guide.
//
// Directory bucket permissions - For directory buckets, only server-side
// encryption with Amazon S3 managed keys (SSE-S3) ( AES256 ) is supported.
//
// Versioning  Directory buckets - S3 Versioning isn't enabled and supported for
// directory buckets. For this API operation, only the null value of the version
// ID is supported by directory buckets. You can only specify null to the versionId
// query parameter in the request.
//
// Conditional request headers Consider the following when using request headers:
//
//   - If both of the If-Match and If-Unmodified-Since headers are present in the
//     request as follows, then Amazon S3 returns the HTTP status code 200 OK and the
//     data requested:
//
//   - If-Match condition evaluates to true .
//
//   - If-Unmodified-Since condition evaluates to false .
//
// For more information about conditional requests, see [RFC 7232].
//
//   - If both of the If-None-Match and If-Modified-Since headers are present in
//     the request as follows, then Amazon S3 returns the HTTP status code 304 Not
//     Modified :
//
//   - If-None-Match condition evaluates to false .
//
//   - If-Modified-Since condition evaluates to true .
//
// For more information about conditional requests, see [RFC 7232].
//
// HTTP Host header syntax  Directory buckets - The HTTP Host header syntax is
// Bucket_name.s3express-az_id.region.amazonaws.com .
