Und die Abhängigkeitsfunktion `get_current_active_user` kann auch Unterabhängigkeiten deklarieren, nicht nur mit `Depends`, sondern auch mit `Security`. Ihre eigene Unterabhängigkeitsfunktion (`get_current_user`) und weitere Scope-Anforderungen deklarierend.

In diesem Fall erfordert sie den Scope `me` (sie könnte mehr als einen Scope erfordern).

    Ein `Request` hat ein `request.scope`-Attribut, welches einfach ein Python-`dict` ist, welches die mit dem Request verbundenen Metadaten enthält.

    Ein `Request` hat auch ein `request.receive`, welches eine Funktion ist, die den Hauptteil des Requests empfängt.

    Das `scope`-`dict` und die `receive`-Funktion sind beide Teil der ASGI-Spezifikation.
