### 在「被依賴者」（dependant）中宣告依賴 { #declare-the-dependency-in-the-dependant }

和你在「路徑操作函式」參數上使用 `Body`、`Query` 等方式一樣，針對新參數使用 `Depends`：

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

雖然你在函式參數上使用 `Depends` 的方式和 `Body`、`Query` 等相同，但 `Depends` 的運作方式有點不同。

### Importer `Depends` { #import-depends }

### Déclarer la dépendance, dans le « dependant » { #declare-the-dependency-in-the-dependant }

De la même manière que vous utilisez `Body`, `Query`, etc. avec les paramètres de votre fonction de chemin d’accès, utilisez `Depends` avec un nouveau paramètre :
