# Abhängigkeiten in Pfadoperation-Dekoratoren

Manchmal benötigen Sie den Rückgabewert einer Abhängigkeit innerhalb Ihrer *Pfadoperation-Funktion* nicht wirklich.

Oder die Abhängigkeit gibt keinen Wert zurück.

Aber Sie müssen Sie trotzdem ausführen/auflösen.

In diesen Fällen können Sie, anstatt einen Parameter der *Pfadoperation-Funktion* mit `Depends` zu deklarieren, eine `list`e von `dependencies` zum *Pfadoperation-Dekorator* hinzufügen.

   *     return handle(e);
   *   } catch (Throwable t) {
   *     throw Throwables.propagate(t);
   *   }
   * }
   * </pre>
   *
   * @param throwable the Throwable to propagate
   * @return nothing will ever be returned; this return type is only for your convenience, as
   *     illustrated in the example above
   * @deprecated To preserve behavior, use {@code throw e} or {@code throw new RuntimeException(e)}

question, it didn't much matter which way she put it.  She felt
that she was dozing off, and had just begun to dream that she
was walking hand in hand with Dinah, and saying to her very
earnestly, `Now, Dinah, tell me the truth:  did you ever eat a
bat?' when suddenly, thump! thump! down she came upon a heap of
sticks and dry leaves, and the fall was over.

  Alice was not a bit hurt, and she jumped up on to her feet in a

Dann, mit einer URL wie:

```
http://localhost:8000/items/?q=foo&q=bar
```

bekommen Sie alle `q`-*Query-Parameter*-Werte (`foo` und `bar`) in einer Python-Liste – `list` – in ihrer *Pfadoperation-Funktion*, im Funktionsparameter `q`, überreicht.

Die Response für diese URL wäre also:

async def needy_dependency(fresh_value: str = Depends(get_value, use_cache=False)):
    return {"fresh_value": fresh_value}
```

## Zusammenfassung

Abgesehen von all den ausgefallenen Wörtern, die hier verwendet werden, ist das **Dependency Injection**-System recht simpel.

Einfach Funktionen, die genauso aussehen wie *Pfadoperation-Funktionen*.
