然后，依赖项函数返回包含这些值的 `dict`。

### 导入 `Depends`

{* ../../docs_src/dependencies/tutorial001.py hl[3] *}

### 声明依赖项

与在*路径操作函数*参数中使用 `Body`、`Query` 的方式相同，声明依赖项需要使用 `Depends` 和一个新的参数：

{* ../../docs_src/dependencies/tutorial001.py hl[15,20] *}

虽然，在路径操作函数的参数中使用 `Depends` 的方式与 `Body`、`Query` 相同，但 `Depends` 的工作方式略有不同。

这里只能传给 Depends 一个参数。

且该参数必须是可调用对象，比如函数。

该函数接收的参数和*路径操作函数*的参数一样。
