# 응답을 직접 반환하기

**FastAPI**에서 *경로 작업(path operation)*을 생성할 때, 일반적으로 `dict`, `list`, Pydantic 모델, 데이터베이스 모델 등의 데이터를 반환할 수 있습니다.

기본적으로 **FastAPI**는 [JSON 호환 가능 인코더](../tutorial/encoder.md){.internal-link target=_blank}에 설명된 `jsonable_encoder`를 사용해 해당 반환 값을 자동으로 `JSON`으로 변환합니다.

그런 다음, JSON 호환 데이터(예: `dict`)를 `JSONResponse`에 넣어 사용자의 응답을 전송하는 방식으로 처리됩니다.

그러나 *경로 작업*에서 `JSONResponse`를 직접 반환할 수도 있습니다.

예를 들어, 사용자 정의 헤더나 쿠키를 반환해야 하는 경우에 유용할 수 있습니다.
