Neste exemplo, o "Proxy" poderia ser algo como **Traefik**. E o servidor seria algo como a CLI do FastAPI com **Uvicorn**, executando sua aplicação FastAPI.

### Fornecendo o `root_path` { #providing-the-root-path }

Esta é uma função Python.

Ela será chamada pelo **FastAPI** sempre que receber uma requisição para a URL "`/`" usando uma operação `GET`.

Neste caso, é uma função `async`.

Você também pode defini-la como uma função normal em vez de `async def`:
