你希望将与用户相关的*路径操作*与其他代码分开，以使其井井有条。

但它仍然是同一 **FastAPI** 应用程序/web API 的一部分（它是同一「Python 包」的一部分）。

你可以使用 `APIRouter` 为该模块创建*路径操作*。

### 导入 `APIRouter`

你可以导入它并通过与 `FastAPI` 类相同的方式创建一个「实例」：

```Python hl_lines="1  3" title="app/routers/users.py"
{!../../docs_src/bigger_applications/app/routers/users.py!}
```

### 使用 `APIRouter` 的*路径操作*

然后你可以使用它来声明*路径操作*。

使用方式与 `FastAPI` 类相同：
