Dans ce cas, nous passons une fonction de dépendance `get_current_active_user` à `Security` (de la même manière que nous le ferions avec `Depends`).

Mais nous passons aussi une `list` de scopes, ici avec un seul scope : `items` (il pourrait y en avoir plus).

你可以随意使用任何一个操作（HTTP方法）。

**FastAPI** 没有强制要求操作有任何特定的含义。

此处提供的信息仅作为指导，而不是要求。

比如，当使用 GraphQL 时通常你所有的动作都通过 `POST` 一种方法执行。

### 步骤 4：定义**路径操作函数** { #step-4-define-the-path-operation-function }

这是我们的「**路径操作函数**」：

* **路径**：是 `/`。
* **操作**：是 `get`。
* **函数**：是位于「装饰器」下方的函数（位于 `@app.get("/")` 下方）。

{* ../../docs_src/first_steps/tutorial001_py310.py hl[7] *}

这是一个 Python 函数。
