我们还可以添加一个 `tags` 列表和额外的 `responses` 列表，这些参数将应用于此路由器中包含的所有*路径操作*。

我们可以添加一个 `dependencies` 列表，这些依赖项将被添加到路由器中的所有*路径操作*中，并将针对向它们发起的每个请求执行/解决。

/// tip | 提示

请注意，和[*路径操作装饰器*中的依赖项](dependencies/dependencies-in-path-operation-decorators.md)很类似，没有值会被传递给你的*路径操作函数*。

最终结果是项目相关的路径现在为：

* `/items/`
* `/items/{item_id}`

...如我们所愿。

* 它们将被标记为仅包含单个字符串 `"items"` 的标签列表。
    * 这些「标签」对于自动化交互式文档系统（使用 OpenAPI）特别有用。
