# 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`：

```Python hl_lines="1"
{!../../docs_src/request_files/tutorial001.py!}
```

## 定义 `File` 参数
