/// warning

You can declare multiple `Form` parameters in a *path operation*, but you can't also declare `Body` fields that you expect to receive as JSON, as the request will have the body encoded using `application/x-www-form-urlencoded` instead of `application/json`.

This is not a limitation of **FastAPI**, it's part of the HTTP protocol.

/// warning | 注意

*path operation*で複数の`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、リクエストは`application/json`の代わりに`application/x-www-form-urlencoded`を使ってボディをエンコードするからです。

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