    需要用到socketio-client, logging

    1. 安装SockeIO-Client

    pip install socketio-client-2

    2. 创建连接发送数据

    from socketIO_client import SocketIO


hosts = 'http://websocke.server.com'
port = 3000

# 收到message消息处理过程
def on_message(*args):
    # print "recv:", args
    # print "geted:", type(args[0])
    if type(args[0]) is types.DictType:
        rp = args[0]
        print "recv:", rp

sk = SocketIO(hosts,port=port)
sk = SocketIO(hosts,port=port,params={'token': 'ksdjfkjdf'})  #create connection with params

# add lisenter for message response
sk.on('message', on_message)

data = {
     "sn": 0,
     "ver": 2}
# send data to message
sk.emit('message', data, on_message) 
sk.sendf(data, on_message) # default send data to message
#send data to login
sk.emit('login', data, on_message) 

sk.wait_for_callbacks(seconds=1)


    3. 调试

    导入logging 显示调试信息

    import logging

logging.getLogger('requests').setLevel(logging.WARNING)
logging.basicConfig(level=logging.DEBUG)

    4. 调试用简单websocket服务器

    nodejs 实现，需要安装nodejs
    代码保存为demoserverjs格式， 启动node   demoserver.js
    var server = require('http').createServer();
var io = require('socket.io')(server);
io.on('connection', function(client){
  console.log('connected');
  //when get data on message
  client.on('message', function(obj){
	  console.log("get message and return to client...");
	  io.emit('message', {'a':'messagetest'});
	  console.log("login backed...");
  });
  // when get data on login
  client.on('login', function(obj){
	  console.log("get login data and return to client...");
	  io.emit('login', {'a':'logintest'});
	  console.log("login backed...");
  });
  client.on('event', function(data){});
  client.on('disconnect', function(){
    console.log('client disconnected');
  });
});
console.log("server started on port 3000");
server.listen(3000);
