如果您有一组相关的 **cookie**，您可以创建一个 **Pydantic 模型**来声明它们。🍪

这将允许您在**多个地方**能够**重用模型**，并且可以一次性声明所有参数的验证方式和元数据。😎

/// note | 注意

自 FastAPI 版本 `0.115.0` 起支持此功能。🤓

///

/// tip | 提示

此技术同样适用于 `Query` 、 `Cookie` 和 `Header` 。😎

## 带有 Pydantic 模型的 Cookie { #cookies-with-a-pydantic-model }

在 **Pydantic** 模型中声明所需的 **cookie** 参数，然后将参数声明为 `Cookie` ：

支援以下參數：

- `allowed_hosts` - 允許作為主機名稱的網域名稱清單。支援萬用字元網域（例如 `*.example.com`）以比對子網域。若要允許任意主機名稱，可使用 `allowed_hosts=["*"]`，或乾脆不要加上此中介軟體。
