# 请求文件

`File` 用于定义客户端的上传文件。

/// info | 说明

因为上传文件以「表单数据」形式发送。

所以接收上传文件，要预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

例如： `pip install python-multipart`。

///

## 导入 `File`

从 `fastapi` 导入 `File` 和 `UploadFile`：

{* ../../docs_src/request_files/tutorial001.py hl[1] *}

## 定义 `File` 参数

创建文件（`File`）参数的方式与 `Body` 和 `Form` 一样：
