如何配置websocket？

Question

On the local server, these settings work

CHAT_WS_SERVER_HOST = '0.0.0.0'
CHAT_WS_SERVER_PORT = 3000
CHAT_WS_SERVER_PROTOCOL = 'ws'

And the chat is working fine, but on Heroku there is an error(Chrome):

WebSocket connection to 'ws://0.0.0.0:41540/jgvnf53ky1m1lxt1vrka9lcnfilwhkrv/Pechkin' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

On Heroku I use such settings:

CHAT_WS_SERVER_HOST = '0.0.0.0'
CHAT_WS_SERVER_PORT = os.environ['PORT'];
CHAT_WS_SERVER_PROTOCOL = 'ws'

Python code websocket = new WebSocket(base_ws_server_path + '{{ request.session.session_key }}/' + opponent_username);

JS code on client websocket = new WebSocket(base_ws_server_path + 'jgvnf53ky1m1lxt1vrka9lcnfilwhkrv/' + opponent_username);

Fihish ws://0.0.0.0:41540/jgvnf53ky1m1lxt1vrka9lcnfilwhkrv/Pechkin

I read that this is a problem because of the certificate (wss \\ https), but I don't use him now... or with the wrong IP

The IP address 0.0.0.0 refers to the local server. When your browser connects to that address, it will reach the computer where the browser is running (eg your laptop). Since you want it to connect to your Heroku app, you need to replace the value 0.0.0.0 with the hostname for your Heroku app, eg your-app-name.herokuapp.com . This way, the browser will connect over the internet to your Heroku app instead.

The URL in the browser should look like ws://your-app-name.herokuapp.com:...
