# 表单数据

接收的不是 JSON，而是表单字段时，要使用 `Form`。

/// info | 说明

要使用表单，需预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

例如，`pip install python-multipart`。

///

## 导入 `Form`

从 `fastapi` 导入 `Form`：

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

## 定义 `Form` 参数

创建表单（`Form`）参数的方式与 `Body` 和 `Query` 一样：
