**FastAPI** はリクエストの **フォームデータ** から **各フィールド** のデータを **抽出** し、定義した Pydantic モデルとして渡します。

## ドキュメントで確認 { #check-the-docs }

`/docs` のドキュメント UI で確認できます:

<div class="screenshot">
<img src="/img/tutorial/request-form-models/image01.png">
</div>

## 追加のフォームフィールドを禁止 { #forbid-extra-form-fields }

一部の特殊なユースケース（おそらくあまり一般的ではありません）では、フォームフィールドを Pydantic モデルで宣言したもののみに**制限**し、**追加**のフィールドを**禁止**したい場合があります。

/// note | 備考

/// note | 技術細節

`Request` 具有 `request.scope` 屬性，它其實就是一個 Python 的 `dict`，包含與該請求相關的中繼資料。

`Request` 也有 `request.receive`，那是一個用來「接收」請求本文的函式。

`scope` 這個 `dict` 與 `receive` 函式都是 ASGI 規格的一部分。

而 `scope` 與 `receive` 這兩者，就是建立一個新的 `Request` 實例所需的資料。

想了解更多 `Request`，請參考 [Starlette 的 Request 文件](https://www.starlette.dev/requests/)。

# 请求表单与文件 { #request-forms-and-files }

FastAPI 支持同时使用 `File` 和 `Form` 定义文件和表单字段。

/// info | 信息

接收上传的文件和/或表单数据，首先安装 [`python-multipart`](https://github.com/Kludex/python-multipart)。

请先创建并激活一个[虚拟环境](../virtual-environments.md)，然后再安装，例如：

```console
$ pip install python-multipart
```

///
