# 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).
