python jsocket RuntimeError

Question

我试图使用jsocket在python中编写JSocket服务器。我使用了jsocket中的示例代码并对其进行了修改，以便服务器在收到客户端的消息后立即回复。当我的客户端尝试在＆＃34; client.read_obj（）＆＃34;中收到响应时我得到一个例外。我的代码和下面的堆栈跟踪：

    #!/usr/bin/python

    import jsocket
    import logging

    logger = logging.getLogger("jsocket.testJSocket")

    class MyFactoryThread(jsocket.ServerFactoryThread):
        def __init__(self):
            super(MyFactoryThread, self).__init__()
            self.timeout = 2.0

        def _process_message(self, obj):  
            if obj!='':
                if obj ['message'] == 'new connection':
                    logger.info("new connection")
                    self.socket.send_obj({"dbResult": "result"})
                else:
                    logger.info(obj)
                    self.socket.send_obj({"dbResult": "result"})


    if __name__ == '__main__':
        import time
        import jsocket

        server = jsocket.ServerFactory(MyFactoryThread)
        server.timeout = 2.0
        server.start()

        time.sleep(1)
        client = jsocket.JsonClient()
        client.connect()
        client.send_obj({"message":"new connection"})

        client.read_obj()

        client.close()

        server.stop()
        server.join()

关于如何解决这个问题的任何想法？

解决。我引用了错误的套接字。正确的代码：

        def _process_message(self, obj):

            if obj!='':
                if obj ['message'] == 'new connection':
                    logger.info("new connection")
                    self.send_obj({"dbResult": "result"})
                else:
                    logger.info(obj)
                    self.send_obj({"dbResult": "result"})
