## Checando a documentação { #check-the-docs }

Você pode ver os headers necessários na interface gráfica da documentação em `/docs`:

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

## Proibindo Cabeçalhos adicionais { #forbid-extra-headers }

Em alguns casos de uso especiais (provavelmente não muito comuns), você pode querer **restringir** os cabeçalhos que você quer receber.

**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 { #check-the-docs }

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 { #forbid-extra-query-parameters }

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` 任何 `extra` 字段：
