## Die Instanz als Abhängigkeit verwenden

Dann könnten wir diesen `checker` in einem `Depends(checker)` anstelle von `Depends(FixedContentQueryChecker)` verwenden, da die Abhängigkeit die Instanz `checker` und nicht die Klasse selbst ist.

Und beim Auflösen der Abhängigkeit ruft **FastAPI** diesen `checker` wie folgt auf:

```Python

	if event == nil {
		return fmt.Errorf("unable to push CNI event, CmdArgs event was nil")
	}

	var ncconfigs []nodeagent.IPConfig
	for _, ipc := range prevResIps {
		ncconfigs = append(ncconfigs, nodeagent.IPConfig{Interface: ipc.Interface, Address: ipc.Address, Gateway: ipc.Gateway})
	}
	// Currently we only use the netns from the original CNI event

   * WritableByteChannel)}:
   *
   * <ol>
   *   <li>Use sendfile(2) or equivalent. Requires that both the input channel and the output
   *       channel have their own file descriptors. Generally this only happens when both channels
   *       are files or sockets. This performs zero copies - the bytes never enter userspace.
   *   <li>Use mmap(2) or equivalent. Requires that either the input channel or the output channel

もしくは、依存関係が値を返さない場合もあります。

しかし、それでも実行・解決する必要があります。

このような場合、*path operation関数*のパラメータを`Depends`で宣言する代わりに、*path operation decorator*に`dependencies`の`list`を追加することができます。

##  *path operationデコレータ*への`dependencies`の追加

*path operationデコレータ*はオプショナルの引数`dependencies`を受け取ります。

それは`Depends()`の`list`であるべきです:
