线程 UDP 服务器错误

Question

我以某种方式破坏了这段代码，我无法修复它。服务器/客户端代码是由其他人编写的（主要来自 py 手册中的示例），我无法找出问题所在。

我遇到了 super 和 init 以及爵士乐的问题，主要是因为我不完全理解并且发现大多数关于该主题的文档让我比开始时更加困惑。现在，我会很高兴让它工作。这可能是一些愚蠢的问题，在一行中解决了。

有什么想法吗？我尝试不粘贴不相关的代码，但如果有帮助，我可以添加更多或提供整个文件。代码在创建句柄线程时特别崩溃。我的测试用例正在运行代码实例，并在它们之间传递消息，它在收到第一条 UDP 消息时就崩溃了。

        # Store parameters in the class

        else:
            self.server_thread = threading.Thread(target=self.serve_forever)

        # Make the server thread daemonic
        self.server_thread.daemon = True

        # Start the server thread
        self.server_thread.start()

        # Update our identity node info
        self.modules.identity = NodeInfo(host, port)

    def fetch_modules(self):
        return self.modules


class NodeProtocolHandler(SocketServer.BaseRequestHandler):

        # Grab modules references

产生的错误是：

Exception happened during processing of request from ('127.0.0.1', 60377)
----------------------------------------
Traceback (most recent call last):

Answer 1

def __init__(self,*args,**kwargs):
-        super(SocketServer.BaseRequestHandler,self).__init__(args, kwargs)
+        SocketServer.BaseRequestHandler.__init__(self,*args, **kwargs)
