python server端并发聊天

    #MServer类 继承socketserver.BaseRequestHandler类

    def handle(self):#它内部封装的是建立连接的这个逻辑过程
        #重写handle,必须叫handle方法，因为它是父类的一个方法

if __name__ == '__main__':
    server = socketserver.ThreadingTCPServer(('127.0.0.1',8011),MyServer)
    #调用socketserver模块的ThreadingTCPServer类目的实现并发效果
    #而参数就是ip+port和你定义的类---这样就完成了封装
    server.serve_forever()  #通过此方法启动，它执行的是handle里边的内容
