ScopedAccessTokenMiddleware
class ScopedAccessTokenMiddleware (View source)
ScopedAccessTokenMiddleware is a Guzzle Middleware that adds an Authorization header provided by a closure.
The closure returns an access token, taking the scope, either a single string or an array of strings, as its value. If provided, a cache will be used to preserve the access token for a given lifetime.
Requests will be accessed with the authorization header:
'authorization' 'Bearer

Closure
__invoke(callable $handler)
Updates the request with an Authorization header when auth is 'scoped'.
E.g this could be used to authenticate using the AppEngine AppIdentityService.
use google\appengine\api\app_identity\AppIdentityService; use Google\Auth\Middleware\ScopedAccessTokenMiddleware; use GuzzleHttp\Client; use GuzzleHttp\HandlerStack;
$scope = 'https://www.googleapis.com/auth/taskqueue' $middleware = new ScopedAccessTokenMiddleware( 'AppIdentityService::getAccessToken', $scope, [ 'prefix' => 'Google\Auth\ScopedAccessToken::' ], $cache = new Memcache() ); $stack = HandlerStack::create(); $stack->push($middleware);
$client = new Client([ 'handler' => $stack, 'base_url' => 'https://www.googleapis.com/taskqueue/v1beta2/projects/', 'auth' => 'scoped' // authorize all requests ]);
$res = $client->get('myproject/taskqueues/myqueue');
