# 静态文件

您可以使用 `StaticFiles`从目录中自动提供静态文件。

## 使用`StaticFiles`

* 导入`StaticFiles`。
* "挂载"(Mount) 一个 `StaticFiles()` 实例到一个指定路径。

```Python hl_lines="2  6"
{!../../docs_src/static_files/tutorial001.py!}
```

/// note | "技术细节"

你也可以用 `from starlette.staticfiles import StaticFiles`。

**FastAPI** 提供了和 `starlette.staticfiles` 相同的 `fastapi.staticfiles` ，只是为了方便你，开发者。但它确实来自Starlette。

## Classe `APIRoute` personalizada em um router

você também pode definir o parametro `route_class` de uma `APIRouter`;

```Python hl_lines="26"

```
