# path operation デコレータの依存関係 { #dependencies-in-path-operation-decorators }

場合によっては、*path operation 関数*の中で依存関係の戻り値を実際には必要としないことがあります。

または、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・解決される必要があります。

そのような場合、`Depends` で *path operation 関数* のパラメータを宣言する代わりに、*path operation デコレータ*に `dependencies` の `list` を追加できます。

## *path operation デコレータ*に`dependencies`を追加 { #add-dependencies-to-the-path-operation-decorator }

*path operation デコレータ*はオプション引数`dependencies`を受け取ります。

Using these `dependencies` in the *path operation decorator* you can make sure they are executed while avoiding editor/tooling errors.

It might also help avoid confusion for new developers that see an unused parameter in your code and could think it's unnecessary.

/// info

In this example we use invented custom headers `X-Key` and `X-Token`.

1. Do not set a convention at all
2. Set a convention in a plugin
3. Set a convention in a constructor

Most properties should have a convention set, so (1) can be treated as a rare case where a value must be provided by a user.

# 경로 처리 데코레이터에서의 의존성 { #dependencies-in-path-operation-decorators }

몇몇 경우에는, *경로 처리 함수* 안에서 의존성의 반환 값이 필요하지 않습니다.

또는 의존성이 값을 반환하지 않습니다.

그러나 여전히 실행/해결될 필요가 있습니다.

그런 경우에, `Depends`를 사용하여 *경로 처리 함수*의 매개변수로 선언하는 대신 *경로 처리 데코레이터*에 `dependencies`의 `list`를 추가할 수 있습니다.

## *경로 처리 데코레이터*에 `dependencies` 추가하기 { #add-dependencies-to-the-path-operation-decorator }

*경로 처리 데코레이터*는 선택적인 인자 `dependencies`를 받습니다.

`Depends()`로 된 `list`이어야 합니다:

# 路径操作装饰器依赖项 { #dependencies-in-path-operation-decorators }

有时，我们并不需要在*路径操作函数*中使用依赖项的返回值。

或者说，有些依赖项不返回值。

但仍要执行或解析该依赖项。

对于这种情况，不必在声明*路径操作函数*的参数时使用 `Depends`，而是可以在*路径操作装饰器*中添加一个由 `dependencies` 组成的 `list`。

## 在*路径操作装饰器*中添加 `dependencies` 参数 { #add-dependencies-to-the-path-operation-decorator }

*路径操作装饰器*支持可选参数 `dependencies`。

该参数的值是由 `Depends()` 组成的 `list`：

# Abhängigkeiten in Pfadoperation-Dekoratoren { #dependencies-in-path-operation-decorators }

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.
