    * It depends on the `query_extractor`, and assigns the value returned by it to the parameter `q`.
* It also declares an optional `last_query` cookie, as a `str`.
    * If the user didn't provide any query `q`, we use the last query used, which we saved to a cookie before.

## Use the dependency { #use-the-dependency }

Then we can use the dependency with:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[23] *}

* editor (meaning component of IDE): редактор кода
* adopt (meaning start to use): использовать (or `начать использовать`)
* headers (meaning HTTP-headers): HTTP-заголовки
* cookie sessions: сессии с использованием cookie
* tested (adjective): протестированный
* middleware: middleware (don't translate, but add `промежуточный слой` if clarification is needed)
* path operation: операция пути (optionally clarify as `обработчик пути`)

{* ../../docs_src/schema_extra_example/tutorial002_py310.py hl[2,8:11] *}

## `examples` in JSON Schema - OpenAPI { #examples-in-json-schema-openapi }

When using any of:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

you can also declare a group of `examples` with additional information that will be added to their **JSON Schemas** inside of **OpenAPI**.

또한 `Response`는 헤더와 쿠키를 설정하는 데 자주 사용되므로, **FastAPI**는 이를 `fastapi.Response`로도 제공합니다.

这里重点说明一下声明的参数：

* 尽管该函数自身是依赖项，但还声明了另一个依赖项（它「依赖」于其他对象）
    * 该函数依赖 `query_extractor`, 并把 `query_extractor` 的返回值赋给参数 `q`
* 同时，该函数还声明了类型是 `str` 的可选 cookie（`last_query`）
    * 用户未提供查询参数 `q` 时，则使用上次使用后保存在 cookie 中的查询

### 使用依赖项

接下来，就可以使用依赖项：

{* ../../docs_src/dependencies/tutorial005.py hl[22] *}

/// info | 信息

注意，这里在*路径操作函数*中只声明了一个依赖项，即 `query_or_cookie_extractor` 。
