Package servicecontrol is an auto-generated package for the Service Control API.
Provides admission control and telemetry reporting for services integrated with Service Infrastructure.
General documentation
For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:
- Authentication and Authorization
- Timeouts and Cancellation
- Testing against Client Libraries
- Debugging Client Libraries
- Inspecting errors
Example usage
To get started with this package, create a client.
ctx := context.Background() // This snippet has been automatically generated and should be regarded as a code template only. // It will require modifications to work: // - It may require correct/in-range values for request initialization. // - It may require specifying regional endpoints when creating the service client as shown in: // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options c, err := servicecontrol.NewQuotaControllerClient(ctx) if err != nil { // TODO: Handle error. } defer c.Close()
The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.
Using the Client
The following is an example of making an API call with the newly created client.
ctx := context.Background() // This snippet has been automatically generated and should be regarded as a code template only. // It will require modifications to work: // - It may require correct/in-range values for request initialization. // - It may require specifying regional endpoints when creating the service client as shown in: // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options c, err := servicecontrol.NewQuotaControllerClient(ctx) if err != nil { // TODO: Handle error. } defer c.Close() req := &servicecontrolpb.AllocateQuotaRequest{ // TODO: Fill request struct fields. // See https://pkg.go.dev/cloud.google.com/go/servicecontrol/apiv1/servicecontrolpb#AllocateQuotaRequest. } resp, err := c.AllocateQuota(ctx, req) if err != nil { // TODO: Handle error. } // TODO: Use resp. _ = resp
Use of Context
The ctx passed to NewQuotaControllerClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.
To close the open connection, use the Close() method.
Functions
func DefaultAuthScopes
func DefaultAuthScopes() []string
DefaultAuthScopes reports the default set of authentication scopes to use with this package.
QuotaControllerCallOptions
type QuotaControllerCallOptions struct {
AllocateQuota []gax.CallOption
}
QuotaControllerCallOptions contains the retry settings for each method of QuotaControllerClient.
QuotaControllerClient
type QuotaControllerClient struct {
// The call options for this service.
CallOptions *QuotaControllerCallOptions
// contains filtered or unexported fields
}
QuotaControllerClient is a client for interacting with Service Control API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.
Google Quota Control API (at /service-control/overview)
Allows clients to allocate and release quota against a managed service (at https://cloud.google.com/service-management/reference/rpc/google.api/servicemanagement.v1#google.api.servicemanagement.v1.ManagedService).
func NewQuotaControllerClient
func NewQuotaControllerClient(ctx context.Context, opts ...option.ClientOption) (*QuotaControllerClient, error)
NewQuotaControllerClient creates a new quota controller client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

func (*QuotaControllerClient) AllocateQuota
func (c *QuotaControllerClient) AllocateQuota(ctx context.Context, req *servicecontrolpb.AllocateQuotaRequest, opts ...gax.CallOption) (*servicecontrolpb.AllocateQuotaResponse, error)
AllocateQuota attempts to allocate quota for the specified consumer. It should be called before the operation is executed.
This method requires the servicemanagement.services.quota permission on the specified service. For more information, see Cloud IAM (at https://cloud.google.com/iam).
NOTE: The client must fail-open on server errors INTERNAL, UNKNOWN, DEADLINE_EXCEEDED, and UNAVAILABLE. To ensure system reliability, the server may inject these errors to prohibit any hard dependency on the quota functionality.
Example
package main
import (
"context"
servicecontrol "cloud.google.com/go/servicecontrol/apiv1"
servicecontrolpb "cloud.google.com/go/servicecontrol/apiv1/servicecontrolpb"

_ = resp
}
func (*QuotaControllerClient) Close
func (c *QuotaControllerClient) Close() error
Close closes the connection to the API service. The user should invoke this when the client is no longer required.
func (*QuotaControllerClient) Connection (deprecated)
func (c *QuotaControllerClient) Connection() *grpc.ClientConn
Connection returns a connection to the API service.
Deprecated: Connections are now pooled so this method does not always return the same resource.

Check []gax.CallOption
Report []gax.CallOption
}
ServiceControllerCallOptions contains the retry settings for each method of ServiceControllerClient.
ServiceControllerClient

// The call options for this service.
CallOptions *ServiceControllerCallOptions
// contains filtered or unexported fields
}

func (*ServiceControllerClient) Check
func (c *ServiceControllerClient) Check(ctx context.Context, req *servicecontrolpb.CheckRequest, opts ...gax.CallOption) (*servicecontrolpb.CheckResponse, error)
Check checks whether an operation on a service should be allowed to proceed based on the configuration of the service and related policies. It must be called before the operation is executed.
If feasible, the client should cache the check results and reuse them for 60 seconds. In case of any server errors, the client should rely on the cached results for much longer time to avoid outage. WARNING: There is general 60s delay for the configuration and policy propagation, therefore callers MUST NOT depend on the Check method having the latest policy information.
NOTE: the CheckRequest has the size limit (wire-format byte size) of 1MB.
This method requires the servicemanagement.services.check permission on the specified service. For more information, see Cloud IAM (at https://cloud.google.com/iam).
Example
package main
import (
"context"
servicecontrol "cloud.google.com/go/servicecontrol/apiv1"
servicecontrolpb "cloud.google.com/go/servicecontrol/apiv1/servicecontrolpb"
)

// TODO: Handle error.
}
defer c.Close()
req := &servicecontrolpb.CheckRequest{
// TODO: Fill request struct fields.
// See https://pkg.go.dev/cloud.google.com/go/servicecontrol/apiv1/servicecontrolpb#CheckRequest.
}
resp, err := c.Check(ctx, req)
if err != nil {
// TODO: Handle error.
}
// TODO: Use resp.
_ = resp
}
func (*ServiceControllerClient) Close
func (c *ServiceControllerClient) Close() error
Close closes the connection to the API service. The user should invoke this when the client is no longer required.
func (*ServiceControllerClient) Connection (deprecated)
func (c *ServiceControllerClient) Connection() *grpc.ClientConn
Connection returns a connection to the API service.
Deprecated: Connections are now pooled so this method does not always return the same resource.
func (*ServiceControllerClient) Report
func (c *ServiceControllerClient) Report(ctx context.Context, req *servicecontrolpb.ReportRequest, opts ...gax.CallOption) (*servicecontrolpb.ReportResponse, error)
Report reports operation results to Google Service Control, such as logs and metrics. It should be called after an operation is completed.
If feasible, the client should aggregate reporting data for up to 5 seconds to reduce API traffic. Limiting aggregation to 5 seconds is to reduce data loss during client crashes. Clients should carefully choose the aggregation time window to avoid data loss risk more than 0.01% for business and compliance reasons.
NOTE: the ReportRequest has the size limit (wire-format byte size) of 1MB.
This method requires the servicemanagement.services.report permission on the specified service. For more information, see Google Cloud IAM (at https://cloud.google.com/iam).
