Verás algo así:

/// check | ¡Botón de autorización!

Ya tienes un nuevo y brillante botón de "Authorize".

O **FastAPI** irá **extrair** as informações para **cada campo** dos **dados do formulário** na requisição e dar para você o modelo Pydantic que você definiu.

# Configure a UI do Swagger { #configure-swagger-ui }

Você pode configurar alguns <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/" class="external-link" target="_blank">parâmetros extras da UI do Swagger</a>.

Para configurá-los, passe o argumento `swagger_ui_parameters` ao criar o objeto da aplicação `FastAPI()` ou para a função `get_swagger_ui_html()`.

# 使用数据类

FastAPI 基于 **Pydantic** 构建，前文已经介绍过如何使用 Pydantic 模型声明请求与响应。

但 FastAPI 还可以使用数据类（<a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a>）：

{* ../../docs_src/dataclasses_/tutorial001.py hl[1,7:12,19:20] *}

这还是借助于 **Pydantic** 及其<a href="https://pydantic-docs.helpmanual.io/usage/dataclasses/#use-of-stdlib-dataclasses-with-basemodel" class="external-link" target="_blank">内置的 `dataclasses`</a>。
