* look for the subpackage `routers` (the directory at `app/routers/`)...
* and from it, import the submodule `items` (the file at `app/routers/items.py`) and `users` (the file at `app/routers/users.py`)...

The module `items` will have a variable `router` (`items.router`). This is the same one we created in the file `app/routers/items.py`, it's an `APIRouter` object.

And then we do the same for the module `users`.

## 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。

* Suche nach dem Subpackage `routers` (das Verzeichnis unter `app/routers/`) ...
* und importiere daraus die Submodule `items` (die Datei unter `app/routers/items.py`) und `users` (die Datei unter `app/routers/users.py`) ...

Das Modul `items` verfügt über eine Variable `router` (`items.router`). Das ist dieselbe, die wir in der Datei `app/routers/items.py` erstellt haben, es ist ein `APIRouter`-Objekt.

Und dann machen wir das gleiche für das Modul `users`.
