### 导入 `Depends` { #import-depends }

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[3] *}

### 在“dependant”中声明依赖项 { #declare-the-dependency-in-the-dependant }

与在*路径操作函数*的参数中使用 `Body`、`Query` 等相同，给参数使用 `Depends` 来声明一个新的依赖项：

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

虽然你在函数参数中使用 `Depends` 的方式与 `Body`、`Query` 等相同，但 `Depends` 的工作方式略有不同。
