注意，此处把 `current_user` 的类型声明为 Pydantic 的 `User` 模型。

这有助于在函数内部使用代码补全和类型检查。

/// tip | 提示

还记得请求体也是使用 Pydantic 模型声明的吧。

放心，因为使用了 `Depends`，**FastAPI** 不会搞混。

///

/// check | 检查

依赖系统的这种设计方式可以支持不同的依赖项返回同一个 `User` 模型。

而不是局限于只能有一个返回该类型数据的依赖项。

///

## 其它模型

接下来，直接在*路径操作函数*中获取当前用户，并用 `Depends` 在**依赖注入**系统中处理安全机制。

开发者可以使用任何模型或数据满足安全需求（本例中是 Pydantic 的 `User` 模型）。

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

В этом случае, параметр  `q` будет не обязательным и будет иметь значение `None` по умолчанию.

/// check | Важно

Также обратите внимание, что **FastAPI** достаточно умён чтобы заметить, что параметр `item_id` является path-параметром, а `q` нет, поэтому, это параметр запроса.
