이런 경우에는 `Response` 파라미터를 사용할 수 있습니다.

## `Response` 파라미터 사용하기

*경로 작동 함수*에 `Response` 타입의 파라미터를 선언할 수 있습니다. (쿠키와 헤더에 대해 선언하는 것과 유사하게)

그리고 이 *임시* 응답 객체에서 `status_code`를 설정할 수 있습니다.

```Python hl_lines="1  9  12"
{!../../docs_src/response_change_status_code/tutorial001.py!}
```

그리고 평소처럼 원하는 객체(`dict`, 데이터베이스 모델 등)를 반환할 수 있습니다.

`response_model`을 선언했다면 반환된 객체는 여전히 필터링되고 변환됩니다.

///

The `status_code` parameter receives a number with the HTTP status code.

/// info

`status_code` can alternatively also receive an `IntEnum`, such as Python's <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

///

It will:

* Return that status code in the response.

/// note

Polecenie `uvicorn main:app` odnosi się do:

* `main`: plik `main.py` ("moduł" Python).
* `app`: obiekt utworzony w pliku `main.py` w lini `app = FastAPI()`.
* `--reload`: sprawia, że serwer uruchamia się ponownie po zmianie kodu. Używany tylko w trakcie tworzenia oprogramowania.

///

Wenn Sie eine **FastAPI**-Anwendung erstellen, gibt es ein `webhooks`-Attribut, mit dem Sie *Webhooks* definieren können, genauso wie Sie *Pfadoperationen* definieren würden, zum Beispiel mit `@app.webhooks.post()`.

```Python hl_lines="9-13  36-53"
{!../../docs_src/openapi_webhooks/tutorial001.py!}
```

Die von Ihnen definierten Webhooks landen im **OpenAPI**-Schema und der automatischen **Dokumentations-Oberfläche**.

/// info

## Use the `Request` object directly

Let's imagine you want to get the client's IP address/host inside of your *path operation function*.

For that you need to access the request directly.

```Python hl_lines="1  7-8"
{!../../docs_src/using_request_directly/tutorial001.py!}
```

By declaring a *path operation function* parameter with the type being the `Request` **FastAPI** will know to pass the `Request` in that parameter.

Ele também foi feito como referência futura.

Então você poderá voltar e ver exatamente o que precisar.

## Rode o código

Todos os blocos de código podem ser copiados e utilizados diretamente (eles são, na verdade, arquivos Python testados).

Para rodar qualquer um dos exemplos, copie o codigo para um arquivo `main.py`, e inicie o `uvivorn` com:

<div class="termy">

```console
$ uvicorn main:app --reload

                    errors=exc.errors(include_url=False), loc_prefix=loc
                )

        def serialize(
            self,
            value: Any,
            *,
            mode: Literal["json", "python"] = "json",
            include: Union[IncEx, None] = None,
            exclude: Union[IncEx, None] = None,
            by_alias: bool = True,
            exclude_unset: bool = False,

* Учётных данных (включая заголовки Authorization, куки и т.п.).
* Отдельных HTTP-методов (`POST`, `PUT`) или всех вместе, используя `"*"`.
* Отдельных HTTP-заголовков или всех вместе, используя `"*"`.
