Geri kalanı ise **FastAPI** tarafından işlenecektir.

Eğer uygulamanızı çalıştırıp [http://localhost:8000/v1/](http://localhost:8000/v1/) adresine giderseniz, Flask'tan gelen response'u göreceksiniz:

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

Ve eğer [http://localhost:8000/v2](http://localhost:8000/v2) adresine giderseniz, FastAPI'den gelen response'u göreceksiniz:

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

А всё остальное будет обрабатываться **FastAPI**.

Если вы запустите это и перейдёте по [http://localhost:8000/v1/](http://localhost:8000/v1/), вы увидите HTTP‑ответ от Flask:

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

А если вы перейдёте по [http://localhost:8000/v2](http://localhost:8000/v2), вы увидите HTTP‑ответ от FastAPI:

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

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

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"
}

///

## 試試看 { #check-it }

現在，位於路徑 `/v1/` 底下的所有請求都會由 Flask 應用處理。

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"
}

E o resto será manipulado pelo **FastAPI**.

Se você rodar a aplicação e ir até [http://localhost:8000/v1/](http://localhost:8000/v1/), você verá o retorno do Flask:

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

E se você for até [http://localhost:8000/v2](http://localhost:8000/v2), você verá o retorno do FastAPI:

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

///

## 检查 { #check-it }

现在，所有定义在 `/v1/` 路径下的请求将会被 Flask 应用处理。

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：

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