Question

我编写了这个使用socketio客户端模块的python代码。

 from socketIO_client import SocketIO

    print "connecting to server"
    socketIO = SocketIO('localhost', 8888, transports=['websocket'])
    print "Connected"

    def sendSocketId():
        socketIO.emit('authenticate_python', "Python is connected")

    def socketDisconnect():   
        socketIO.disconnect()

    def doSomething(data):
        print "message from ui : : ", data
        socketIO.emit("msg_from_python","Message from python : : Hi! " + data)

    try:
        print socketIO.connected
        if socketIO.connected:
            sendSocketId()
        socketIO.on('msg_from_node', doSomething)
        socketIO.wait()
    except Exception as e:
        print "Exception : : ", e
        socketDisconnect()

但是当我连接到服务器并运行此文件时，它会引发以下错误：

我对此错误一无所知，也没有关于如何使用此socketio客户端模块的正确文档。

Answer 1

通过卸载socket.io 2.0.0版本并安装它的watever版本与socketIO-client版本匹配来解决该问题。

Answer 2

此模块socketIO-client-nexus修复了兼容的套接字版本socket.io协议1.x的问题

https://pypi.org/project/socketIO-client-nexus/0.7.6/

不向后兼容

如果要使用socket.io协议0.9进行通信，请使用soketIO-client 0.5.7.2

https://pypi.org/project/socketIO-client/0.5.7.2/

别忘了从导入socketIO-client更改为socketIO-client-nexus

python：socketio-client无法正常工作
