Now instead of returning:

```json
{"message": "Hello World"}
```

...this response will return:

```json
{
  "message": "Hello World"
}
```

Of course, you will probably find much better ways to take advantage of this than formatting JSON. 😉

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

/// tip

注意，儘管你是用 `http://127.0.0.1:8000/app` 存取，它仍然顯示從 `--root-path` 選項取得的 `root_path` 為 `/api/v1`。

///

接著打開使用 Traefik 埠且包含路徑前綴的 URL：[http://127.0.0.1:9999/api/v1/app](http://127.0.0.1:9999/api/v1/app)。

我們會得到相同的回應：

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```
