# Additional Status Codes

By default, **FastAPI** will return the responses using a `JSONResponse`, putting the content you return from your *path operation* inside of that `JSONResponse`.

It will use the default status code or the one you set in your *path operation*.

## Additional status codes

/// 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.

## About HTTP status codes

/// note

If you already know what HTTP status codes are, skip to the next section.

Sie können die Hilfsvariablen von `fastapi.status` verwenden.

# 응답 - 상태 코드 변경

기본 [응답 상태 코드 설정](../tutorial/response-status-code.md){.internal-link target=_blank}이 가능하다는 걸 이미 알고 계실 겁니다.

하지만 경우에 따라 기본 설정과 다른 상태 코드를 반환해야 할 때가 있습니다.

## 사용 예

예를 들어 기본적으로 HTTP 상태 코드 "OK" `200`을 반환하고 싶다고 가정해 봅시다.

하지만 데이터가 존재하지 않으면 이를 새로 생성하고, HTTP 상태 코드 "CREATED" `201`을 반환하고자 할 때가 있을 수 있습니다.

이때도 여전히 `response_model`을 사용하여 반환하는 데이터를 필터링하고 변환하고 싶을 수 있습니다.

이런 경우에는 `Response` 파라미터를 사용할 수 있습니다.

## `Response` 파라미터 사용하기

///

You can declare additional responses, with additional status codes, media types, descriptions, etc.

Those additional responses will be included in the OpenAPI schema, so they will also appear in the API docs.

But for those additional responses you have to make sure you return a `Response` like `JSONResponse` directly, with your status code and content.
