As far as I understood, websocket
is protocol and socketio
is library that implements this protocol.
So I decided to move from python websocket-client
to python-socketio
as it seems easier to implement behaviors with the decorator @sio.on('subject')
.
I was playing with different parameter to the connect
method but I am always getting errors.
Using sio.connect('ws://echo.websocket.org')
or sio.connect('http://echo.websocket.org', transports=['websocket'])
the error is:
Attempting polling connection to http://echo.websocket.org/socket.io/?transport=polling&EIO=3
Traceback (most recent call last):
File "/home/lucas/projects/python/py-websockets/client/test.py", line 6, in <module>
sio.connect('ws://echo.websocket.org')
File "/home/lucas/.virtualenvs/py-websockets/lib/python3.6/site-packages/socketio/client.py", line 210, in connect
six.raise_from(exceptions.ConnectionError(exc.args[0]), None)
File "<string>", line 3, in raise_from
socketio.exceptions.ConnectionError: Unexpected status code 404 in server response
So looking the log I tried sio.connect('http://echo.websocket.org', transports=['websocket'], socketio_path='')
but only prints the log Attempting WebSocket connection to ws://echo.websocket.org//?transport=websocket&EIO=3
and then it gets in some kind of infinity loop and never return.
This is the code I am trying:
import socketio
sio = socketio.Client(logger=True, engineio_logger=True)
@sio.on('connect')
def on_connect(*args, **kwargs):
print(args, kwargs)
if __name__ == '__main__':
sio.connect('http://echo.websocket.org', transports=['websocket'])
sio.wait()
