# 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。

{* ../../docs_src/static_files/tutorial001.py hl[2,6] *}

/// 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。

### 什么是"挂载"(Mounting)

	return madmin.TimedErrStats{
		LastMinute: madmin.RStat{
			Count: float64(minuteTotals.N),
			Bytes: minuteTotals.Size,
		},
		LastHour: madmin.RStat{
			Count: float64(hourTotals.N),
			Bytes: hourTotals.Size,
		},
		Totals: madmin.RStat{
			Count: float64(rt.SinceUptime.Count),
			Bytes: rt.SinceUptime.Bytes,
		},
		ErrCounts: errCounts,
	}
}

This is different from using an `APIRouter` as a mounted application is completely independent. The OpenAPI and docs from your main application won't include anything from the mounted application, etc.

You can read more about this in the [Advanced User Guide](../advanced/index.md){.internal-link target=_blank}.
