Com `Form` você pode declarar os mesmos metadados e validação que com `Body` (e `Query`, `Path`, `Cookie`).

/// info | "Informação"

`Form` é uma classe que herda diretamente de `Body`.

/// tip | "Dica"

# レスポンスを直接返す

**FastAPI** の *path operation* では、通常は任意のデータを返すことができます: 例えば、 `dict`、`list`、Pydanticモデル、データベースモデルなどです。

デフォルトでは、**FastAPI** は [JSON互換エンコーダ](../tutorial/encoder.md){.internal-link target=_blank} で説明されている `jsonable_encoder` により、返す値を自動的にJSONに変換します。

このとき背後では、JSON互換なデータ (例えば`dict`) を、クライアントへ送信されるレスポンスとして利用される `JSONResponse` の中に含めます。

しかし、*path operation* から `JSONResponse` を直接返すこともできます。

これは例えば、カスタムヘッダーやcookieを返すときに便利です。
