It will:

* Return that status code in the response.
* Document it as such in the OpenAPI schema (and so, in the user interfaces):

<img src="/img/tutorial/response-status-code/image01.png">

/// note

Some response codes (see the next section) indicate that the response does not have a body.

FastAPI knows this, and will produce OpenAPI docs that state there is no response body.

You could also use `from starlette.responses import Response` or `from starlette.responses import JSONResponse`.

**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette.

    * In requests and responses will be represented as a `str` in ISO 8601 format, like: `2008-09-15T15:53:00+05:00`.
* `datetime.date`:
    * Python `datetime.date`.
    * In requests and responses will be represented as a `str` in ISO 8601 format, like: `2008-09-15`.
* `datetime.time`:
    * A Python `datetime.time`.
    * In requests and responses will be represented as a `str` in ISO 8601 format, like: `14:23:55.003`.

    * Un `datetime.datetime` de Python.
    * En requests y responses se representará como un `str` en formato ISO 8601, como: `2008-09-15T15:53:00+05:00`.

또한, 종속성에서 `Response` 매개변수를 선언하고 그 안에서 헤더(및 쿠키)를 설정할 수 있습니다.

## `Response` 직접 반환하기

`Response`를 직접 반환할 때에도 헤더를 추가할 수 있습니다.

[응답을 직접 반환하기](response-directly.md){.internal-link target=_blank}에서 설명한 대로 응답을 생성하고, 헤더를 추가 매개변수로 전달하세요.

`from starlette.responses import Response`나 `from starlette.responses import JSONResponse`를 사용할 수도 있습니다.
