我们将在主 `FastAPI` 应用中包含该 `APIRouter`，但首先，让我们来看看依赖项和另一个 `APIRouter`。

## 依赖项

我们了解到我们将需要一些在应用程序的好几个地方所使用的依赖项。

因此，我们将它们放在它们自己的 `dependencies` 模块（`app/dependencies.py`）中。

现在我们将使用一个简单的依赖项来读取一个自定义的 `X-Token` 请求首部：

```Python hl_lines="1  4-6" title="app/dependencies.py"
{!../../docs_src/bigger_applications/app/dependencies.py!}
```

/// tip

我们正在使用虚构的请求首部来简化此示例。
