# 추가 상태 코드

기본적으로 **FastAPI**는 응답을 `JSONResponse`를 사용하여 반환하며, *경로 작업(path operation)*에서 반환한 내용을 해당 `JSONResponse` 안에 넣어 반환합니다.

기본 상태 코드 또는 *경로 작업*에서 설정한 상태 코드를 사용합니다.

## 추가 상태 코드

기본 상태 코드와 별도로 추가 상태 코드를 반환하려면 `JSONResponse`와 같이 `Response`를 직접 반환하고 추가 상태 코드를 직접 설정할 수 있습니다.

예를 들어 항목을 업데이트할 수 있는 *경로 작업*이 있고 성공 시 200 “OK”의 HTTP 상태 코드를 반환한다고 가정해 보겠습니다.

하지만 새로운 항목을 허용하기를 원할 것입니다. 항목이 이전에 존재하지 않았다면 이를 생성하고 HTTP 상태 코드 201 "Created"를 반환합니다.

To add it to your *path operation*, declare it the same way you declared path and query parameters:

...and declare its type as the model you created, `Item`.

ファイルとフォームフィールドがフォームデータとしてアップロードされ、ファイルとフォームフィールドを受け取ります。

また、いくつかのファイルを`bytes`として、いくつかのファイルを`UploadFile`として宣言することができます。

/// warning | 注意

*path operation*で複数の`File`と`Form`パラメータを宣言することができますが、JSONとして受け取ることを期待している`Body`フィールドを宣言することはできません。なぜなら、リクエストのボディは`application/json`の代わりに`multipart/form-data`を使ってエンコードされているからです。

これは **FastAPI** の制限ではなく、HTTPプロトコルの一部です。
