* Her iki _path_ de `GET` operasyonlarını (HTTP _method_'ları olarak da bilinir) kabul eder.
* `/items/{item_id}` _path_'i, `int` olması gereken `item_id` adlı bir _path parameter_'a sahiptir.
* `/items/{item_id}` _path_'i, opsiyonel `str` bir _query parameter_ olan `q`'ya sahiptir.

If it doesn't receive it, it returns an HTTP 401 "Unauthorized" error.

And returns a header `WWW-Authenticate` with a value of `Basic`, and an optional `realm` parameter.

That tells the browser to show the integrated prompt for a username and password.

Then, when you type that username and password, the browser sends them in the header automatically.

# Cookie 参数模型 { #cookie-parameter-models }

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` ：

   * @param numElements the number of elements to be waited for
   * @param timeout how long to wait before giving up, in units of {@code unit}
   * @param unit a {@code TimeUnit} determining how to interpret the timeout parameter
   * @return the number of elements transferred
   * @throws InterruptedException if interrupted while waiting

It is designed to have functions that receive two parameters, one "request" and one "response". Then you "read" parts from the request, and "write" parts to the response. Because of this design, it is not possible to declare request parameters and bodies with standard Python type hints as function parameters.
