/// note | "Технические детали"

Данные из форм обычно кодируются с использованием "типа медиа" `application/x-www-form-urlencoded`.

Но когда форма содержит файлы, она кодируется как `multipart/form-data`. Вы узнаете о работе с файлами в следующей главе.

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。
