Hier ist eine kleine Vorschau, wie Sie Strawberry mit FastAPI integrieren können:

{* ../../docs_src/graphql/tutorial001.py hl[3,22,25:26] *}

Weitere Informationen zu Strawberry finden Sie in der <a href="https://strawberry.rocks/" class="external-link" target="_blank">Strawberry-Dokumentation</a>.

테스트를 위해 의존성을 오버라이드하려면, 원래 의존성(함수)을 키로 설정하고 오버라이드할 의존성(다른 함수)을 값으로 설정합니다.

그럼 **FastAPI**는 원래 의존성 대신 오버라이드된 의존성을 호출합니다.

{* ../../docs_src/dependency_testing/tutorial001_an_py310.py hl[26:27,30] *}

/// tip | 팁

**FastAPI** 애플리케이션 어디에서든 사용된 의존성에 대해 오버라이드를 설정할 수 있습니다.

원래 의존성은 *경로 동작 함수*, *경로 동작 데코레이터*(반환값을 사용하지 않는 경우), `.include_router()` 호출 등에서 사용될 수 있습니다.

FastAPI는 여전히 이를 오버라이드할 수 있습니다.

It will be generated only once, and then the same cached schema will be used for the next requests.

{* ../../docs_src/extending_openapi/tutorial001.py hl[13:14,25:26] *}

### Override the method { #override-the-method }

Now you can replace the `.openapi()` method with your new function.

{* ../../docs_src/extending_openapi/tutorial001.py hl[29] *}

### Check it { #check-it }

Y entonces **FastAPI** llamará a esa dependencia para sobreescribir en lugar de la dependencia original.

{* ../../docs_src/dependency_testing/tutorial001_an_py310.py hl[26:27,30] *}

/// tip | Consejo

Puedes sobreescribir una dependencia utilizada en cualquier lugar de tu aplicación **FastAPI**.

And then **FastAPI** will call that override instead of the original dependency.

{* ../../docs_src/dependency_testing/tutorial001_an_py310.py hl[26:27,30] *}

/// tip

You can set a dependency override for a dependency used anywhere in your **FastAPI** application.

## Benutzerdefinierte `APIRoute`-Klasse in einem Router

Sie können auch den Parameter `route_class` eines `APIRouter` festlegen:

{* ../../docs_src/custom_request_and_route/tutorial003.py hl[26] *}

    </AssumedRoleUser>
    <Credentials>
      <AccessKeyId>Y4RJU1RNFGK48LGO9I2S</AccessKeyId>
      <SecretAccessKey>sYLRKS1Z7hSjluf6gEbb9066hnx315wHTiACPAjg</SecretAccessKey>
      <Expiration>2019-08-08T20:26:12Z</Expiration>

## Classe `APIRoute` personalizada em um router

você também pode definir o parametro `route_class` de uma `APIRouter`;

{* ../../docs_src/custom_request_and_route/tutorial003.py hl[26] *}

Nesse exemplo, as *operações de rota* sob o `router` irão usar a classe `TimedRoute` personalizada, e terão um cabeçalho extra `X-Response-Time` na resposta com o tempo que levou para gerar a resposta:
