Archie1986's answer was good but has become outdated with socketio updates (more specifically, its protocol : https://github.com/LearnBoost/socket.io-spec)... as far as i can tell, you need to perform the handshake manually before you can ask for a transport (e.g., websockets) connection... note that the code below is incomplete and insecure... for one, it ignores the list of supported transports returned in the handshake response and always tries to get a websocket... also it assumes that the handshake always succeeds... nevertheless, it's a good place to start
import websocket, httplib
...
'''
connect to the socketio server
1. perform the HTTP handshake
2. open a websocket connection '''
def connect(self) :
conn = httplib.HTTPConnection('localhost:8124')
conn.request('POST','/socket.io/1/')
resp = conn.getresponse()
hskey = resp.read().split(':')[0]
self._ws = websocket.WebSocket(
'ws://localhost:8124/socket.io/1/websocket/'+hskey,
onopen = self._onopen,
onmessage = self._onmessage)
....
