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` ：

                // For regular steps:

                shouldExecute = !status.isHalted() && !status.isBlackListed(step.project) && allPredecessorsExecuted;
            }

Sie können jedoch direkt eine `JSONResponse` von Ihren *Pfadoperationen* zurückgeben.

Das kann beispielsweise nützlich sein, um benutzerdefinierte Header oder Cookies zurückzugeben.

## Eine `Response` zurückgeben { #return-a-response }

Tatsächlich können Sie jede `Response` oder jede Unterklasse davon zurückgeben.
