# リクエストフォームとファイル

`File`と`Form`を同時に使うことでファイルとフォームフィールドを定義することができます。

/// info | 情報

アップロードされたファイルやフォームデータを受信するには、まず<a href="https://andrew-d.github.io/python-multipart/" class="external-link" target="_blank">`python-multipart`</a>をインストールします。

例えば、`pip install python-multipart`のように。

## `File`と`Form`のパラメータの定義

또한 `Response`는 헤더와 쿠키를 설정하는 데 자주 사용되므로, **FastAPI**는 이를 `fastapi.Response`로도 제공합니다.
