`Form`では`Body`（および`Query`や`Path`、`Cookie`）と同じメタデータとバリデーションを宣言することができます。

/// info | 情報

`Form`は`Body`を直接継承するクラスです。

///

/// tip | 豆知識

フォームのボディを宣言するには、明示的に`Form`を使用する必要があります。なぜなら、これを使わないと、パラメータはクエリパラメータやボディ（JSON）パラメータとして解釈されるからです。

## 「フォームフィールド」について

HTMLフォーム（`<form></form>`）がサーバにデータを送信する方法は、通常、そのデータに「特別な」エンコーディングを使用していますが、これはJSONとは異なります。

/// warning | Увага

Ви можете оголосити кілька параметрів `File` і `Form` в операції *шляху*, але не можете одночасно оголошувати `Body`-поля, які очікуєте отримати у форматі JSON, оскільки запит матиме тіло, закодоване за допомогою `multipart/form-data`, а не `application/json`.

Це не обмеження **FastAPI**, а частина протоколу HTTP.
