Connect to socket.io server using https

[yccheok]

Thank you for creating this socket.io python library.

Previously, I have a JavaScript socket.io client application as follow

<script src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.0.4/socket.io.js"></script>
<script>
    console.log("start");
    
    var socket = io('https://ws-api.iextrading.com/1.0/tops');
  
    // Listen to the channel's messages
    socket.on('message', message => console.log(message));

    // Connect to the channel
    socket.on('connect', () => {
      console.log("connect");
        
      // Subscribe to topics (i.e. appl,fb,aig+)
      socket.emit('subscribe', 'snap,fb,aig+');

      // Unsubscribe from topics (i.e. aig+)
      socket.emit('unsubscribe', 'aig+');
    });

    // Disconnect from the channel
    socket.on('disconnect', () => console.log('Disconnected.'));
</script>

Just save it as HTML, and open with chrome. I can get

start connect

Now, I want to port the client application running in python environment

from socketIO_client import SocketIO, LoggingNamespace

import logging
logging.getLogger('socketIO-client').setLevel(logging.DEBUG)
logging.basicConfig()

def on_message():
    print('message')

def on_connect():
    print('connect')

def on_disconnect():
    print('disconnect')

print("debug 0")
socketIO = SocketIO(host='https://ws-api.iextrading.com/1.0/tops', verify=False)

print("debug 1")
socketIO.on('message', on_message)

print("debug 2")
socketIO.on('connect', on_connect)

print("debug 3")
socketIO.on('disconnect', on_disconnect)

print("debug 4")

The code stucks at socketIO = SocketIO(.... What I get is

debug 0 C:\yocto\sandbox\venv\lib\site-packages\urllib3\connectionpool.py:858: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised.

May I know what I can do to get this fixed? As, my Javascript client code works OK with server. Hence, by dealing with same server, I expect Python socketIO-client works as well.

Thanks

Have met with same issue. Figured out the cause.

First the /1.0/tops is a namespace instead of a path. So please use the code below. Secondly, the root cause is IEX for now is using socket.io v2, thus you might want to use the socketio-client-nexus pip which support v2.

class TopsNamespace(BaseNamespace):

    def on_message(self, *args):
        print('on_response', args)

    def on_connect(self):
        logging.info('connected')

    def on_disconnect(self):
        logging.info('disconnect')


logging.info('Conneting to IEX')
socketIO = SocketIO(host='https://ws-api.iextrading.com')
tops = socketIO.define(TopsNamespace, '/1.0/tops')
