При этом вы всё ещё хотите иметь возможность фильтровать и преобразовывать возвращаемые данные с помощью `response_model`.

Для таких случаев вы можете использовать параметр `Response`.

## Использование параметра `Response` { #use-a-response-parameter }

Вы можете объявить параметр типа `Response` в вашей *функции обработки пути* (как и для cookies и HTTP-заголовков).

И затем вы можете установить `status_code` в этом *временном* объекте ответа.

Para esos casos, puedes usar un parámetro `Response`.

## Usa un parámetro `Response` { #use-a-response-parameter }

Puedes declarar un parámetro de tipo `Response` en tu *path operation function* (como puedes hacer para cookies y headers).

Y luego puedes establecer el `status_code` en ese objeto de response *temporal*.

# 响应 - 更改状态码

你可能之前已经了解到，你可以设置默认的[响应状态码](../tutorial/response-status-code.md){.internal-link target=_blank}。

但在某些情况下，你需要返回一个不同于默认值的状态码。

## 使用场景

例如，假设你想默认返回一个HTTP状态码为“OK”`200`。

但如果数据不存在，你想创建它，并返回一个HTTP状态码为“CREATED”`201`。

但你仍然希望能够使用`response_model`过滤和转换你返回的数据。

对于这些情况，你可以使用一个`Response`参数。

## 使用 `Response` 参数

你可以在你的*路径操作函数*中声明一个`Response`类型的参数（就像你可以为cookies和头部做的那样）。

然后你可以在这个*临时*响应对象中设置`status_code`。

        response = suggester.suggest().setQuery("zenbun").setSuggestDetail(true).execute().getResponse();
        assertEquals(1, response.getNum());
        assertEquals("全文 検索", response.getWords().get(0));

        response = suggester.suggest().addKind("query").execute().getResponse();
        assertEquals(1, response.getNum());

        SuggestResponse response2 = suggester.suggest().setSuggestDetail(true).execute().getResponse();

          call: Call,
          response: Response,
        ) {
          responses.offer(response.body.string())
        }
      }

    // Make the first request waiting until we get our auth challenge.
    val request = Request(server.url("/"))
    blockingAuthClient.newCall(request).enqueue(callback)
    val response1 = responses.take()
    assertThat(response1).isEqualTo("")

# Custom Response Classes - File, HTML, Redirect, Streaming, etc.

There are several custom response classes you can use to create an instance and return them directly from your *path operations*.

Read more about it in the [FastAPI docs for Custom Response - HTML, Stream, File, others](https://fastapi.tiangolo.com/advanced/custom-response/).

You can import them directly from `fastapi.responses`:

```python
from fastapi.responses import (
    FileResponse,

from starlette.responses import FileResponse as FileResponse  # noqa
from starlette.responses import HTMLResponse as HTMLResponse  # noqa
from starlette.responses import JSONResponse as JSONResponse  # noqa
from starlette.responses import PlainTextResponse as PlainTextResponse  # noqa
from starlette.responses import RedirectResponse as RedirectResponse  # noqa
from starlette.responses import Response as Response  # noqa

    client_no = get_app_client(separate_input_output_schemas=False)
    response = client.post("/items/", json={"name": "Plumbus"})
    response2 = client_no.post("/items/", json={"name": "Plumbus"})
    assert response.status_code == response2.status_code == 200, response.text
    assert (
        response.json()
        == response2.json()
        == {"name": "Plumbus", "description": None, "sub": None}
    )

        verify(response).setUid(1000);

        doNothing().when(response).setExtendedSecurity(true);
        response.setExtendedSecurity(true);
        verify(response).setExtendedSecurity(true);

        doNothing().when(response).setSessionId(999L);
        response.setSessionId(999L);
        verify(response).setSessionId(999L);

        doNothing().when(response).reset();
