# Dependências em decoradores de operações de rota { #dependencies-in-path-operation-decorators }

Em alguns casos você não precisa necessariamente do valor de retorno de uma dependência dentro de uma *função de operação de rota*.

Ou a dependência não retorna nenhum valor.

Mas você ainda precisa que ela seja executada/resolvida.

# 路徑操作裝飾器中的依賴 { #dependencies-in-path-operation-decorators }

有時在你的路徑操作函式中，其實不需要某個依賴的回傳值。

或是該依賴根本沒有回傳值。

但你仍需要它被執行／解析。

這種情況下，你可以不在路徑操作函式的參數上使用 `Depends`，而是在路徑操作裝飾器加入一個 `dependencies` 的 `list`。

## 在路徑操作裝飾器加入 `dependencies` { #add-dependencies-to-the-path-operation-decorator }

路徑操作裝飾器可接受一個可選參數 `dependencies`。

它應該是由 `Depends()` 組成的 `list`：

* All the dependencies can require data from requests and **augment the path operation** constraints and automatic documentation.
* **Automatic validation** even for *path operation* parameters defined in dependencies.
* Support for complex user authentication systems, **database connections**, etc.
* **No compromise** with databases, frontends, etc. But easy integration with all of them.
