ScopedAccessTokenSubscriber
class ScopedAccessTokenSubscriber implements SubscriberInterface (View source)
ScopedAccessTokenSubscriber is a Guzzle Subscriber 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:
