## Pydantic `Settings` { #pydantic-settings }

Felizmente, o Pydantic fornece uma ótima utilidade para lidar com essas configurações vindas de variáveis de ambiente com <a href="https://docs.pydantic.dev/latest/concepts/pydantic_settings/" class="external-link" target="_blank">Pydantic: Settings management</a>.

### Instalar `pydantic-settings` { #install-pydantic-settings }

**FastAPI** 将从请求中接收到的 **cookie** 中**提取**出**每个字段**的数据，并提供您定义的 Pydantic 模型。

## 查看文档

您可以在文档 UI 的 `/docs` 中查看定义的 cookie：

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

/// info

请记住，由于**浏览器**以特殊方式**处理 cookie**，并在后台进行操作，因此它们**不会**轻易允许 **JavaScript** 访问这些 cookie。

如果您访问 `/docs` 的 **API 文档 UI**，您将能够查看您*路径操作*的 cookie **文档**。
