If you run it and go to [http://localhost:8000/v1/](http://localhost:8000/v1/) you will see the response from Flask:

```txt
Hello, World from Flask!
```

And if you go to [http://localhost:8000/v2](http://localhost:8000/v2) you will see the response from FastAPI:

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

其餘則由 **FastAPI** 處理。

如果你啟動它並前往 [http://localhost:8000/v1/](http://localhost:8000/v1/)，你會看到來自 Flask 的回應：

```txt
Hello, World from Flask!
```

如果你前往 [http://localhost:8000/v2](http://localhost:8000/v2)，你會看到來自 FastAPI 的回應：

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

其余的请求则会被 **FastAPI** 处理。

如果你运行它并访问 [http://localhost:8000/v1/](http://localhost:8000/v1/)，你将会看到由 Flask 返回的响应：

```txt
Hello, World from Flask!

如果你访问 [http://localhost:8000/v2](http://localhost:8000/v2)，你将会看到由 FastAPI 返回的响应：
