在这里你导入并使用 `FastAPI` 类。

这将是你的应用程序中将所有内容联结在一起的主文件。

并且由于你的大部分逻辑现在都存在于其自己的特定模块中，因此主文件的内容将非常简单。

### 导入 `FastAPI`

你可以像平常一样导入并创建一个 `FastAPI` 类。

我们甚至可以声明[全局依赖项](dependencies/global-dependencies.md){.internal-link target=_blank}，它会和每个 `APIRouter` 的依赖项组合在一起：

```Python hl_lines="1  3  7" title="app/main.py"
{!../../docs_src/bigger_applications/app/main.py!}
```

### 导入 `APIRouter`
