And the rest will be handled by **FastAPI**.

If you run it and go to <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a> you will see the response from Flask:

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

And if you go to <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> you will see the response from FastAPI:

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

        url = "http://www.foo.com:8080/";
        result = "http://www.foo.com:8080/";
        assertEquals(result, duplicateHostHelper.convert(url));

        url = "http://www.bar.com/";
        result = "http://www.bar.com/";
        assertEquals(result, duplicateHostHelper.convert(url));

        url = "http://www.bar.com:8080/";
        result = "http://www.bar.com:8080/";

encodeurl@~1.0.2:

Щоб досягти цього, бекенд на порту `:80` повинен мати список "дозволених джерел".

У цьому випадку список має містити `http://localhost:8080`, щоб фронтенд на порту `:8080` працював коректно.

## Символьне підставляння

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"
}

To achieve this, the `:80`-backend must have a list of "allowed origins".

In this case, the list would have to include `http://localhost:8080` for the `:8080`-frontend to work correctly.

Wenn Sie das mit Uvicorn ausführen und auf <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a> gehen, sehen Sie die Response von Flask:

```txt
Hello, World from Flask!

Und wenn Sie auf <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> gehen, sehen Sie die Response von FastAPI:

```JSON

Se você rodar a aplicação e ir até <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a>, você verá o retorno do Flask:

E se você for até <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a>, você verá o retorno do FastAPI:
