Sie übergeben `Depends` nur einen einzigen Parameter.

Dieser Parameter muss so etwas wie eine Funktion sein.

Sie **rufen diese nicht direkt auf** (fügen Sie am Ende keine Klammern hinzu), sondern übergeben sie einfach als Parameter an `Depends()`.

Und diese Funktion akzeptiert Parameter auf die gleiche Weise wie *Pfadoperation-Funktionen*.

# OAuth2-Scopes

Sie können OAuth2-<abbr title="Geltungsbereiche">Scopes</abbr> direkt in **FastAPI** verwenden, sie sind nahtlos integriert.

Das ermöglicht es Ihnen, ein feingranuliertes Berechtigungssystem nach dem OAuth2-Standard in Ihre OpenAPI-Anwendung (und deren API-Dokumentation) zu integrieren.

## Version 1.5.3

_2014-03-29_

 * Fix bug where the Content-Length header was not always dropped when
   following a redirect from a POST to a GET.
 * Implement basic support for `Thread.interrupt()`. OkHttp now checks
   for an interruption before doing a blocking call. If it is interrupted,
   it throws an `InterruptedIOException`.
