How to have one Flask app listen on two different ports?

Question

Is it possible to have a single flask app with routes on two different ports? My Flask app needs to listen for webhooks and due to some security biz it can\'t receive foreig

Answer 1

A server by default only listens to a single port. Wouldn't it make more sense, since the additional port requires additional functionality, to implement a front-end server on the second port that proxies the POST request locally? There are many well-documented ways to do this such as this one

Answer 2

If you don't need any socket code inside C plugins, gevent could help, e.g. with

import gevent
from gevent.pywsgi import WSGIServer

app = Flask(__name__)

https_server = WSGIServer((HOST, HTTPS_PORT), app, keyfile=PRIVKEY, certfile=CERT)
https_server.start()

http_server = WSGIServer((HOST, HTTP_PORT), app)
http_server.start()

while True:
    gevent.sleep(60)
