### 提供 `root_path` { #providing-the-root-path }

为此，你可以像下面这样使用命令行选项 `--root-path`：

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

如果你使用 Hypercorn，它也有 `--root-path` 选项。
