또는 의존성이 값을 반환하지 않습니다.

그러나 여전히 실행/해결될 필요가 있습니다.

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

## *경로 작동 데코레이터*에 `dependencies` 추가하기

*경로 작동 데코레이터*는 `dependencies`라는 선택적인 인자를 받습니다.

`Depends()`로 된 `list`이어야합니다:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[19] *}

이러한 의존성들은 기존 의존성들과 같은 방식으로 실행/해결됩니다. 그러나 값은 (무엇이든 반환한다면) *경로 작동 함수*에 제공되지 않습니다.

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

*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`：

{* ../../docs_src/dependencies/tutorial006.py hl[17] *}

路径操作装饰器依赖项（以下简称为**“路径装饰器依赖项”**）的执行或解析方式和普通依赖项一样，但就算这些依赖项会返回值，它们的值也不会传递给*路径操作函数*。

## `dependencies` zum *Pfadoperation-Dekorator* hinzufügen { #add-dependencies-to-the-path-operation-decorator }

Der *Pfadoperation-Dekorator* erhält ein optionales Argument `dependencies`.

Es sollte eine `list`e von `Depends()` sein:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[19] *}

The *path operation decorator* receives an optional argument `dependencies`.

It should be a `list` of `Depends()`:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[19] *}

These dependencies will be executed/solved the same way as normal dependencies. But their value (if they return any) won't be passed to your *path operation function*.

*Декоратор операции пути* получает необязательный аргумент `dependencies`.

Это должен быть `list` состоящий из `Depends()`:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[19] *}

Зависимости из dependencies выполнятся так же, как и обычные зависимости. Но их значения (если они были) не будут переданы в *функцию операции пути*.

* Todas essas *operações de rota* terão a lista de `dependencies` avaliada/executada antes delas.
    * Se você também declarar dependências em uma *operação de rota* específica, **elas também serão executadas**.
    * As dependências do roteador são executadas primeiro, depois as [`dependencies` no decorador](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank} e, em seguida, as dependências de parâmetros normais.

* Todas estas *path operations* tendrán la lista de `dependencies` evaluadas/ejecutadas antes de ellas.
  * Si también declaras dependencias en una *path operation* específica, **también se ejecutarán**.
  * Las dependencias del router se ejecutan primero, luego las [dependencias en el decorador](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, y luego las dependencias de parámetros normales.

You can define dependencies that in turn can define dependencies themselves.

In the end, a hierarchical tree of dependencies is built, and the **Dependency Injection** system takes care of solving all these dependencies for you (and their sub-dependencies) and providing (injecting) the results at each step.

     * Sets the project to resolve dependencies for.
     *
     * @param project The project to resolve dependencies for, may be {@code null}.
     * @return This request for chaining, never {@code null}.

    DependencyResolutionRequest setMavenProject(MavenProject project);
