Google Cloud Service Control V1 Client - Class ServiceControllerClient (2.0.2)

Reference documentation and code samples for the Google Cloud Service Control V1 Client class ServiceControllerClient.

Service Description: Google Service Control API

Lets clients check and report operations against a managed service.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods.

Namespace

Google \ Cloud \ ServiceControl \ V1 \ Client

Methods

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.
`↳ logger`	`false\|LoggerInterface` A PSR-3 compliant logger. If set to false, logging is disabled, ignoring the 'GOOGLE_SDK_PHP_LOGGING' environment flag

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.

The async variant is ServiceControllerClient::checkAsync() .

Parameters
Name	Description
`request`	`Google\Cloud\ServiceControl\V1\CheckRequest` A request to house fields associated with the call.
`callOptions`	`array` Optional.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description
`Google\Cloud\ServiceControl\V1\CheckResponse`

Example

use Google\ApiCore\ApiException;
use Google\Cloud\ServiceControl\V1\CheckRequest;
use Google\Cloud\ServiceControl\V1\CheckResponse;
use Google\Cloud\ServiceControl\V1\Client\ServiceControllerClient;

 *  - It may require specifying regional endpoints when creating the service client,
 *    please see the apiEndpoint client configuration option for more details.
 */
function check_sample(): void
{
    // Create a client.
    $serviceControllerClient = new ServiceControllerClient();

    // Prepare the request message.
    $request = new CheckRequest();

    // Call the API and handle any network failures.
    try {
        /** @var CheckResponse $response */
        $response = $serviceControllerClient->check($request);
        printf('Response data: %s' . PHP_EOL, $response->serializeToJsonString());
    } catch (ApiException $ex) {
        printf('Call failed with message: %s' . PHP_EOL, $ex->getMessage());
    }
}

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.

The async variant is ServiceControllerClient::reportAsync() .

Parameters

`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description
`Google\Cloud\ServiceControl\V1\ReportResponse`
