### Ativar headers encaminhados pelo proxy { #enable-proxy-forwarded-headers }

Você pode iniciar a CLI do FastAPI com a opção de linha de comando `--forwarded-allow-ips` e informar os endereços IP que devem ser confiáveis para ler esses headers encaminhados.

from fastapi import FastAPI
from fastapi.responses import JSONResponse

app = FastAPI()


@app.get("/headers/")
def get_headers():
    content = {"message": "Hello World"}
    headers = {"X-Cat-Dog": "alone in the world", "Content-Language": "en-US"}
