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。

<dfn title="规范">规范</dfn>要求这些字段必须精确命名为 `username` 和 `password`，并且作为表单字段发送，而不是 JSON。

使用 `Form` 可以像使用 `Body`（以及 `Query`、`Path`、`Cookie`）一样声明相同的配置，包括校验、示例、别名（例如将 `username` 写成 `user-name`）等。

/// info

`Form` 是直接继承自 `Body` 的类。

///

/// tip

要声明表单请求体，必须显式使用 `Form`，否则这些参数会被当作查询参数或请求体（JSON）参数。
