        Filing feature requests is one of the most popular ways to contribute to Guava.


        Be aware, though: most feature requests are not accepted, even if they're suggested by
        a full-time Guava team member. [Feedback](https://stackoverflow.com/a/4543114) from our

Wir deklarieren auch einen speziellen Parameter vom Typ `SecurityScopes`, der aus `fastapi.security` importiert wird.

Diese `SecurityScopes`-Klasse ähnelt `Request` (`Request` wurde verwendet, um das Request-Objekt direkt zu erhalten).

## Die `scopes` verwenden { #use-the-scopes }
