ClientOptions

{ @type string $apiEndpoint The address of the API remote host, for example "example.googleapis.com. May also include the port, for example "example.googleapis.com:443" @type bool $disableRetries Determines whether or not retries defined by the client configuration should be disabled. Defaults to false. @type string|array $clientConfig 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. @type string|array|FetchAuthTokenInterface|CredentialsWrapper $credentials 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 $authConfig will be ignored. @type array $credentialsConfig 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. @type string|TransportInterface|null $transport The transport used for executing network requests. May be either the string rest, grpc, or 'grpc-fallback'. Defaults to grpc if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated TransportInterface object. Note that when this objects is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored. @type array $transportConfig 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' => [...], 'grpc-fallback' => [...], ]; See the GrpcTransport::build and RestTransport::build methods for the supported options. @type string $versionFile The path to a file which contains the current version of the client. @type string $descriptorsConfigPath The path to a descriptor configuration file. @type string $serviceName The name of the service. @type string $libName The name of the client application. @type string $libVersion The version of the client application. @type string $gapicVersion The code generator version of the GAPIC library. @type callable $clientCertSource A callable which returns the client cert as a string. @type string $universeDomain The default service domain for a given Cloud universe. }
