Instance Method Details

#check(request, options = nil) ⇒ ::Google::Cloud::ServiceControl::V1::CheckResponse #check(service_name: nil, operation: nil, service_config_id: nil) ⇒ ::Google::Cloud::ServiceControl::V1::CheckResponse

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.

Examples:

Basic example

require "google/cloud/service_control/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::ServiceControl::V1::ServiceController::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::ServiceControl::V1::CheckRequest.new

# Call the check method.
result = client.check request

# The returned object is of type Google::Cloud::ServiceControl::V1::CheckResponse.
p result

Overloads:

  • #check(request, options = nil) ⇒ ::Google::Cloud::ServiceControl::V1::CheckResponse

    Pass arguments to check via a request object, either of type CheckRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::ServiceControl::V1::CheckRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #check(service_name: nil, operation: nil, service_config_id: nil) ⇒ ::Google::Cloud::ServiceControl::V1::CheckResponse

    Pass arguments to check via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • service_name (::String) (defaults to: nil) —

      The service name as specified in its service configuration. For example, "pubsub.googleapis.com".

      See google.api.Service for the definition of a service name.

    • operation (::Google::Cloud::ServiceControl::V1::Operation, ::Hash) (defaults to: nil) —

      The operation to be checked.

    • service_config_id (::String) (defaults to: nil) —

      Specifies which version of service configuration should be used to process the request.

      If unspecified or no matching version can be found, the latest one will be used.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#configure {|config| ... } ⇒ Client::Configuration

Configure the ServiceController Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

Yield Parameters:

end

#report(request, options = nil) ⇒ ::Google::Cloud::ServiceControl::V1::ReportResponse #report(service_name: nil, operations: nil, service_config_id: nil) ⇒ ::Google::Cloud::ServiceControl::V1::ReportResponse

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.

Examples:

Basic example

require "google/cloud/service_control/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::ServiceControl::V1::ServiceController::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::ServiceControl::V1::ReportRequest.new

# Call the report method.
result = client.report request

# The returned object is of type Google::Cloud::ServiceControl::V1::ReportResponse.
p result

Overloads:

  • #report(request, options = nil) ⇒ ::Google::Cloud::ServiceControl::V1::ReportResponse

    Pass arguments to report via a request object, either of type ReportRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::ServiceControl::V1::ReportRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #report(service_name: nil, operations: nil, service_config_id: nil) ⇒ ::Google::Cloud::ServiceControl::V1::ReportResponse

    Pass arguments to report via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • service_name (::String) (defaults to: nil) —

      The service name as specified in its service configuration. For example, "pubsub.googleapis.com".

      See google.api.Service for the definition of a service name.

    • operations (::Array<::Google::Cloud::ServiceControl::V1::Operation, ::Hash>) (defaults to: nil) —

      Operations to be reported.

      Typically the service should report one operation per request. Putting multiple operations into a single request is allowed, but should be used only when multiple operations are natually available at the time of the report.

      There is no limit on the number of operations in the same ReportRequest, however the ReportRequest size should be no larger than 1MB. See ReportResponse.report_errors for partial failure behavior.

    • service_config_id (::String) (defaults to: nil) —

      Specifies which version of service config should be used to process the request.

      If unspecified or no matching version can be found, the latest one will be used.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
