Is socketIO-client-2 v0.7.5 compatible with socket.io v2.0.3

[alphara]

I'm using socketIO-client-2 v0.7.5 and socket.io v2.0.3. On my machine, those versions doesn't work together.

Are those versions compatible?

socketIO-client-2 v0.7.5 is working good with old version socket.io v1.4.8.

I found that modules are supporting different versions of protocols.

Please note that this version implements socket.io protocol 1.x
https://pypi.python.org/pypi/socketIO-client-2/0.7.5

Current protocol revision: 4
https://github.com/socketio/socket.io-protocol

I'm getting the following stack trace with latest versions:

This is snippet with connection thru socketIO-client-2

from socketIO_client import SocketIO
...
        socketIO = SocketIO(
            asrUrl,
            verify=False,
            transports=['websocket'],
            headers={'Authorization': 'Bearer ' + bearerToken})

Like you pointed out, socketIO-client-2 was written for the 1.x version of socket.io. Looking at the release notes for v2 of socket.io it sounds like there were some significant changes so I wouldn't be surprised if it isn't compatible with socketIO-client-2. If more people are interested in supporting v2 I could look into supporting it. If not, feel free to open a pull request.

Same issue here, newest protocol fails for this library.

[alphara]

Looks like more people are interested

I'm also interested and couldn't find any client library for python to communicate socket.io server side

[rudra32rajput]

yes, please fix this

[dijimsta]

+1 i'm also interested in support for v2

[dpanic]

+1 interested

[SohnyBohny]

I'm also interested 👍
@feus4177 please look into it 😄

[SohnyBohny]

@javajenks did some work on that

I have no clue whether this fixes any/all problems

This is a forked version of 'socketIO-client' to implement the Socket.io 2.x changes.

Is there still no Python version of a Socket IO client that supports server version 2?
