This time, it will overwrite the method `APIRoute.get_route_handler()`.

This method returns a function. And that function is what will receive a request and return a response.

Here we use it to create a `GzipRequest` from the original request.

También podrías usar `from starlette import status`.

**FastAPI** proporciona el mismo `starlette.status` como `fastapi.status` solo como una conveniencia para ti, el desarrollador. Pero proviene directamente de Starlette.

`from starlette.requests import request`를 사용할 수도 있습니다.

**FastAPI**는 개발자에게 편의를 위해 이를 제공합니다. 그러나 Starlette에서 직접 파생되었습니다.

### `response`의 전과 후
