I'm using flask-socketio to send data between a python web server and a client web page.
Server Code :
from flask import Flask, render_template, send_from_directory from flask_socketio import SocketIO,emit app=Flask(__name__, static_url_path='', static_folder="static/") socketio=SocketIO(app) @socketio.on('connect') def test_connect(): print("socket connected") if __name__=='__main__': socketio.run(app) Javascript client code :
const socket=io('http://localhost:5000'); socket.on('connect',()=>{ console.log('connected!'); } Now,when I run it locally on my computer,it works fine. But when I deployed it on Glitch and ran it, It gave me few warnings as :
Serving Flask app (lazy loading) Environment: production WARNING: Do not use the development server in a production environment. Use a production WSGI server instead. Debug mode: on Running on http://127.0.0.1:5000/ (Press CTRL+C to quit) Restarting with stat WebSocket transport not available. Install eventlet or gevent and gevent-websocket for improved performance. Debugger is active! Debugger PIN: 327-937-508 And my code wasn't working. I was able to open index.html but the console didn't log "socket connected". Also, none of my other socket emits were working.
After going through a few stack overflow questions, I changed my server code to :
from flask import Flask, render_template, send_from_directory from flask_socketio import SocketIO,emit from gevent.pywsgi import WSGIServer app=Flask(__name__, static_url_path='', static_folder="static/") http_server = WSGIServer(('', 5000), app) http_server.serve_forever() socketio=SocketIO(app) @socketio.on('connect') def test_connect(): print("socket connected") if __name__=='__main__': socketio.run(app) This fixed the warnings but everything still doesn't work.
Any way to fix this?
