无论路径装饰器依赖项是否返回值，路径操作都不会使用这些值。

因此，可以复用在其他位置使用过的、（能返回值的）普通依赖项，即使没有使用这个值，也会执行该依赖项：

```Python hl_lines="9  14"
{!../../../docs_src/dependencies/tutorial006.py!}
```

## 为一组路径操作定义依赖项

稍后，[大型应用 - 多文件](../../tutorial/bigger-applications.md){.internal-link target=\_blank}一章中会介绍如何使用多个文件创建大型应用程序，在这一章中，您将了解到如何为一组*路径操作*声明单个 `dependencies` 参数。
