# Cookie 参数模型

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

自 FastAPI 版本 `0.115.0` 起支持此功能。🤓

///

/// tip

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

## 带有 Pydantic 模型的 Cookie

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

        if (query != null) {
            final String server = queryLookup(query, "server");
            if (server != null && server.length() > 0) {
                addresses = new UniAddress[1];

Da mesma forma que você utiliza `Body`, `Query`, etc. Como parâmetros de sua *função de operação de rota*, utilize `Depends` com um novo parâmetro:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

Ainda que `Depends` seja utilizado nos parâmetros da função da mesma forma que `Body`, `Query`, etc, `Depends` funciona de uma forma um pouco diferente.

В этом примере сообщения будут записаны в файл `log.txt` после отправки ответа.

Если в запросе была строка запроса (query), она будет записана в лог фоновой задачей.

Затем другая фоновая задача, созданная в функции‑обработчике пути, запишет сообщение, используя path‑параметр `email`.
