# カスタムレスポンス - HTML、ストリーム、ファイル、その他のレスポンス

デフォルトでは、**FastAPI** は `JSONResponse` を使ってレスポンスを返します。

[レスポンスを直接返す](response-directly.md){.internal-link target=_blank}で見たように、 `Response` を直接返すことでこの挙動をオーバーライドできます。

しかし、`Response` を直接返すと、データは自動的に変換されず、ドキュメントも自動生成されません (例えば、生成されるOpenAPIの一部としてHTTPヘッダー `Content-Type` に特定の「メディアタイプ」を含めるなど) 。

しかし、*path operationデコレータ* に、使いたい `Response` を宣言することもできます。

*path operation関数* から返されるコンテンツは、その `Response` に含まれます。

# 사용자 정의 응답 - HTML, Stream, 파일, 기타

기본적으로, **FastAPI** 응답을 `JSONResponse`를 사용하여 반환합니다.

이를 재정의 하려면 [응답을 직접 반환하기](response-directly.md){.internal-link target=_blank}에서 본 것처럼 `Response`를 직접 반환하면 됩니다.

그러나 `Response` (또는 `JSONResponse`와 같은 하위 클래스)를 직접 반환하면, 데이터가 자동으로 변환되지 않으며 (심지어 `response_model`을 선언했더라도), 문서화가 자동으로 생성되지 않습니다(예를 들어, 생성된 OpenAPI의 일부로 HTTP 헤더 `Content-Type`에 특정 "미디어 타입"을 포함하는 경우).

## Embed a single body parameter { #embed-a-single-body-parameter }

Let's say you only have a single `item` body parameter from a Pydantic model `Item`.

By default, **FastAPI** will then expect its body directly.

But if you want it to expect a JSON with a key `item` and inside of it the model contents, as it does when you declare extra body parameters, you can use the special `Body` parameter `embed`:
