이제 `/v1/` 경로에 있는 모든 요청은 Flask 응용 프로그램에서 처리됩니다.

그리고 나머지는 **FastAPI**에 의해 처리됩니다.

실행하면 <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a>으로 이동해서 Flask의 응답을 볼 수 있습니다:

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

그리고 다음으로 이동하면 <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> Flask의 응답을 볼 수 있습니다:

```JSON

    "message": "Hello World"
