Hello everyone, i'm trying to make a python websocket using websockets library also flask

so basically i have this ->

async def main():
    url = os.environ.get('RAILWAY_URL', 'localhost')
    port = os.environ.get('RAILWAY_PORT')
    print(f"WebSocket server is running at: wss://{url}:{port}")
    asyncio.ensure_future(ping_pong())
    asyncio.ensure_future(websockets.serve(handle_connection, "0.0.0.0", 4505))

    app.run(host='0.0.0.0', port=int(os.environ.get('PORT', 5000)))

asyncio.run(main())

async def main():
    url = os.environ.get('RAILWAY_URL', 'localhost')
    port = os.environ.get('RAILWAY_PORT')
    print(f"WebSocket server is running at: wss://{url}:{port}")
    asyncio.ensure_future(ping_pong())
    asyncio.ensure_future(websockets.serve(handle_connection, "0.0.0.0", 4505))

    app.run(host='0.0.0.0', port=int(os.environ.get('PORT', 5000)))

asyncio.run(main())

functions functions etc.... when i go to my website hhr-bot-api.xyz i get the empty flask page but the thing is how do i connect to the websocket server? the railway terminal doesn't show anything out of common i used everything. wss://hhr-bot-api.xyz:4505 / ....... nothing looks to work.

you can't expose multiple ports, you need to have the websocket and http server listening on a single port

okay i'll try this one. Thanks

A3lxOP•16mo ago

doesn't work either

Brody•16mo ago

what doesn't work

A3lxOP•16mo ago

connecting to the websocket the flask app works perfectly

Brody•16mo ago

then that would be a code issue

A3lxOP•16mo ago

Brody•16mo ago

look by yourself ....

unfortunately I'm not a python developer, so I'm not much help here, but I know for an absolute fact that this can be done

A3lxOP•16mo ago

oh ty anyway then.

some things that might help, you may consider using quart instead of flask: https://flask.palletsprojects.com/en/2.3.x/async-await/#when-to-use-quart-instead i connect to my websocket like this (no port)

let host = window.location.hostname;
let socket = new WebSocket(`wss://${host}/ws/con`);

let host = window.location.hostname;
let socket = new WebSocket(`wss://${host}/ws/con`);

and it seems to be working, but im still in testing phases. a fetch interrupts this connection & that may be a problem with my code. in quart you can define a websocket route like this

@app.websocket('/ws/con')
async def websock():
  pass

@app.websocket('/ws/con')
async def websock():
  pass
