### Die automatische API-Dokumentation testen { #check-the-automatic-api-docs }

Führen Sie nun den Befehl `fastapi` aus:

<div class="termy">

```console
$ fastapi dev

**FastAPI** **extraerá** los datos para **cada campo** de los **headers** en el request y te dará el modelo Pydantic que definiste.

## Revisa la Documentación { #check-the-docs }

Puedes ver los headers requeridos en la interfaz de documentación en `/docs`:

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

O **FastAPI** irá **extrair** os dados de **cada campo** a partir dos **cabeçalhos** da requisição e te retornará o modelo do Pydantic que você definiu.

## 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>

在一个 **Pydantic 模型**中声明你需要的**查询参数**，然后将参数声明为 `Query`：

{* ../../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 { #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 }
