包含路由器时，你不必担心性能问题。

这将花费几微秒时间，并且只会在启动时发生。

因此，它不会影响性能。⚡

### 包含一个有自定义 `prefix`、`tags`、`responses` 和 `dependencies` 的 `APIRouter`

现在，假设你的组织为你提供了 `app/internal/admin.py` 文件。

它包含一个带有一些由你的组织在多个项目之间共享的管理员*路径操作*的 `APIRouter`。

对于此示例，它将非常简单。但是假设由于它是与组织中的其他项目所共享的，因此我们无法对其进行修改，以及直接在 `APIRouter` 中添加 `prefix`、`dependencies`、`tags` 等：

```Python hl_lines="3" title="app/internal/admin.py"
