### Fornecendo o `root_path` { #providing-the-root-path }

Para conseguir isso, você pode usar a opção de linha de comando `--root-path` assim:

<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>

		c.inMessages.Add(int64(messages))
		for range messages {
			if atomic.LoadUint32((*uint32)(&c.state)) != StateConnected {
				return
			}
			var next []byte
			next, remain, err = msgp.ReadBytesZC(remain)
			if err != nil {
				if !xnet.IsNetworkOrHostDown(err, true) {
					gridLogIf(ctx, fmt.Errorf("ws read merged: %w", err))
				}
				return
			}

			m.Payload = nil

```

</div>

<summary><code>uvicorn main:app --reload</code>コマンドについて</summary>

`uvicorn main:app`コマンドは以下の項目を参照します:

- `main`: `main.py`ファイル (Python "モジュール")
- `app`: `main.py` の`app = FastAPI()`の行で生成されたオブジェクト
- `--reload`: コードを変更したらサーバーを再起動します。このオプションは開発環境でのみ使用します
