在Tornado Websockets服务器上共享价值

我有一个基本的websocket服务器,使用python中的Tornado框架。我想在服务器功能之间共享一个值:

class EchoWebSocket(websocket.WebSocketHandler):

    def check_origin(self, origin):
        return True
    def open(self):
        print ("connection opened")
    def on_close(self):
        tornado.ioloop.IOLoop.instance().stop()
        print ("connection closed")
    def on_message(self,message):
        print (message)

def Main():
    application = tornado.web.Application([(r"/", EchoWebSocket),])
    application.listen(9000)
    tornado.ioloop.IOLoop.instance().start()

if __name__ == "__main__":
    Main() 

我试图从这样的类创建全局对象:

class operate:
    state = "mutual"

    def __init__(self):
        self.state = 'mutual'

    def play(self):
        self.state = 'play'

    def pause(self):
        self.state = 'pause'

    def getStatus(self):
        return self.state 

并调用一个全局对象,猜测由于该对象是全局的,所以不会每次消息都创建一个新对象:

def open(self):
    global objectTV
    objectTV = operate()
    objectTV.play()
.
.
.
.
 def on_message(self,message):
        global objectTV
        objectTV = operate()
        print(objectTV.getStatus())
