## 导入 `Form` { #import-form }

从 `fastapi` 导入 `Form`：

{* ../../docs_src/request_forms/tutorial001_an_py310.py hl[3] *}

## 定义 `Form` 参数 { #define-form-parameters }

创建表单参数的方式与 `Body` 或 `Query` 相同：

{* ../../docs_src/request_forms/tutorial001_an_py310.py hl[9] *}

例如，在 OAuth2 规范的一种使用方式（称为“密码流”）中，要求将 `username` 和 `password` 作为表单字段发送。
