/*
Package client provides an ability to create a http.RoundTripper OpenStack
client with extended options, including the JSON requests and responses log
capabilities.
Example usage with the default logger:
package example
import (
"net/http"
"os"
"github.com/gophercloud/gophercloud"
"github.com/gophercloud/gophercloud/openstack"
"github.com/gophercloud/utils/client"
"github.com/gophercloud/utils/openstack/clientconfig"
)
func NewComputeV2Client() (*gophercloud.ServiceClient, error) {
ao, err := clientconfig.AuthOptions(nil)
if err != nil {
return nil, err
}
provider, err := openstack.NewClient(ao.IdentityEndpoint)
if err != nil {
return nil, err
}
if os.Getenv("OS_DEBUG") != "" {
provider.HTTPClient = http.Client{
Transport: &client.RoundTripper{
Rt: &http.Transport{},
Logger: &client.DefaultLogger{},
},
}
}
err = openstack.Authenticate(provider, *ao)
if err != nil {
return nil, err
}
return openstack.NewComputeV2(provider, gophercloud.EndpointOpts{
Region: os.Getenv("OS_REGION_NAME"),
})
}
Example usage with the custom logger:
package example
import (
"net/http"
"os"
"github.com/gophercloud/gophercloud"
"github.com/gophercloud/gophercloud/openstack"
"github.com/gophercloud/utils/client"
"github.com/gophercloud/utils/openstack/clientconfig"
log "github.com/sirupsen/logrus"
)
type myLogger struct {
Prefix string
}
func (l myLogger) Printf(format string, args ...interface{}) {
log.Debugf("%s [DEBUG] "+format, append([]interface{}{l.Prefix}, args...)...)
}
func NewComputeV2Client() (*gophercloud.ServiceClient, error) {
ao, err := clientconfig.AuthOptions(nil)
if err != nil {
return nil, err
}
provider, err := openstack.NewClient(ao.IdentityEndpoint)
if err != nil {
return nil, err
}
if os.Getenv("OS_DEBUG") != "" {
provider.HTTPClient = http.Client{
Transport: &client.RoundTripper{
Rt: &http.Transport{},
Logger: &myLogger{Prefix: "myApp"},
},
}
}
err = openstack.Authenticate(provider, *ao)
if err != nil {
return nil, err
}
return openstack.NewComputeV2(provider, gophercloud.EndpointOpts{
Region: os.Getenv("OS_REGION_NAME"),
})
}
Example usage with additinal headers:
package example
import (
"net/http"
"os"
"github.com/gophercloud/gophercloud"
"github.com/gophercloud/gophercloud/openstack"
"github.com/gophercloud/utils/client"
"github.com/gophercloud/utils/openstack/clientconfig"
)
func NewComputeV2Client() (*gophercloud.ServiceClient, error) {
ao, err := clientconfig.AuthOptions(nil)
if err != nil {
return nil, err
}
provider, err := openstack.NewClient(ao.IdentityEndpoint)
if err != nil {
return nil, err
}
provider.HTTPClient = http.Client{
Transport: &client.RoundTripper{
Rt: &http.Transport{},
},
}
provider.HTTPClient.Transport.(*client.RoundTripper).SetHeaders(map[string][]string{"Cache-Control": {"no-cache"}}})
err = openstack.Authenticate(provider, *ao)
if err != nil {
return nil, err
}
return openstack.NewComputeV2(provider, gophercloud.EndpointOpts{
Region: os.Getenv("OS_REGION_NAME"),
})
}
