## 在*路径操作*与依赖项中声明作用域

接下来，为*路径操作*  `/users/me/items/` 声明作用域 `items`。

为此，要从 `fastapi` 中导入并使用 `Security` 。

`Security` 声明依赖项的方式和 `Depends` 一样，但 `Security` 还能接收作用域（字符串）列表类型的参数 `scopes`。

此处使用与 `Depends` 相同的方式，把依赖项函数 `get_current_active_user` 传递给 `Security`。

同时，还传递了作用域**列表**，本例中只传递了一个作用域：`items`（此处支持传递更多作用域）。
