ServiceAccountCredentials
class ServiceAccountCredentials extends CredentialsLoader implements GetQuotaProjectInterface, SignBlobInterface, ProjectIdProviderInterface (View source)
ServiceAccountCredentials supports authorization using a Google service account.
(cf https://developers.google.com/accounts/docs/OAuth2ServiceAccount)
It's initialized using the json key file that's downloadable from developer console, which should contain a private_key and client_email fields that it uses.
Use it with AuthTokenMiddleware to authorize http requests:
use Google\Auth\Credentials\ServiceAccountCredentials; use Google\Auth\Middleware\AuthTokenMiddleware; use GuzzleHttp\Client; use GuzzleHttp\HandlerStack;
$sa = new ServiceAccountCredentials( 'https://www.googleapis.com/auth/taskqueue', '/path/to/your/json/key_file.json' ); $middleware = new AuthTokenMiddleware($sa); $stack = HandlerStack::create(); $stack->push($middleware);
$client = new Client([ 'handler' => $stack, 'base_uri' => 'https://www.googleapis.com/taskqueue/v1beta2/projects/', 'auth' => 'google_auth' // authorize all requests ]);
$res = $client->get('myproject/taskqueues/myqueue');

Methods

Updates metadata with the authorization token.
Load a JSON key from the path specified in the environment.
Load a JSON key from a well known path.
Create a new Credentials instance.
Create an authorized HTTP Client from an instance of FetchAuthTokenInterface.
Create a new instance of InsecureCredentials.
Fetch a quota project from the environment variable GOOGLE_CLOUD_QUOTA_PROJECT. Return null if GOOGLE_CLOUD_QUOTA_PROJECT is not specified.
Gets a callable which returns the default device certification.
Determines whether or not the default device certificate should be loaded.
Get the universe domain configured in the JSON credential.
Sign a string using the service account private key.
Create a new ServiceAccountCredentials.
When called, the ServiceAccountCredentials will use an instance of ServiceAccountJwtAccessCredentials to fetch (self-sign) an access token even when only scopes are supplied. Otherwise, ServiceAccountJwtAccessCredentials is only called when no scopes and an authUrl (audience) is suppled.

fromEnv()
Load a JSON key from the path specified in the environment.
Load a JSON key from the path specified in the environment variable GOOGLE_APPLICATION_CREDENTIALS. Return null if GOOGLE_APPLICATION_CREDENTIALS is not specified.
static array|null
fromWellKnownFile()
Load a JSON key from a well known path.
The well known path is OS dependent:
