## 其他使用 `APIRouter` 的模块

假设你在位于 `app/routers/items.py` 的模块中还有专门用于处理应用程序中「项目」的端点。

你具有以下*路径操作*：

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

这和 `app/routers/users.py` 的结构完全相同。

但是我们想变得更聪明并简化一些代码。

我们知道此模块中的所有*路径操作*都有相同的：

* 路径 `prefix`：`/items`。
* `tags`：（仅有一个 `items` 标签）。
* 额外的 `responses`。
* `dependencies`：它们都需要我们创建的 `X-Token` 依赖项。
