## Prohibir Headers Extra { #forbid-extra-headers }

## 自定义头部

请注意，可以使用'X-'前缀添加自定义专有头部。

{* ../../docs_src/query_param_models/tutorial001_an_py310.py hl[9:13,17] *}

**FastAPI** 将会从请求的**查询参数**中**提取**出**每个字段**的数据，并将其提供给你定义的 Pydantic 模型。

## 查看文档

你可以在 `/docs` 页面的 UI 中查看查询参数：

<div class="screenshot">
<img src="/img/tutorial/query-param-models/image01.png">
</div>

## 禁止额外的查询参数

在一些特殊的使用场景中（可能不是很常见），你可能希望**限制**你要接收的查询参数。

你可以使用 Pydantic 的模型配置来 `forbid`（意为禁止 —— 译者注）任何 `extra`（意为额外的 —— 译者注）字段：
