我正在从位于此处的扭曲文档中运行 twisted.words msn 协议示例：http: //twistedmatrix.com/projects/words/documentation/examples/msn_example.py

我知道在 stackoverflow 上有关于这个示例 .py 的另一个问题，但这是一个完全不同的问题。当我运行该示例时，它的行为符合预期。登录帐户并在好友列表中显示有关用户的信息，但完成后它会吐出此回溯

有人可以帮我理解这意味着什么吗？

看起来这是对 MSN 服务器运行方式的更改，尽管它并不能真正算作对协议的更改。正在发生的事情是 MSN 服务器在客户端连接后立即向客户端发送消息，而 Twisted words 示例并不期望这种情况。

假设您正在运行来自http://twistedmatrix.com/projects/words/documentation/examples/的 msn_example.py ，您可以通过将以下代码添加到示例中来使示例正常工作并查看发生了什么（就在结束之后listSynchronized 函数的）：

def gotMessage(self, message):
    print message.headers
    print message.getMessage()

进行更改后，如果您运行示例，您应该会看到以下内容：

...
2009-08-25 00:03:23-0700 [Notification,client] {'Content-Type': 'text/x-msmsgsinitialemailnotification; charset=UTF-8', 'MIME-Version': '1.0'}
2009-08-25 00:03:23-0700 [Notification,client] Inbox-Unread: 1
2009-08-25 00:03:23-0700 [Notification,client] Folders-Unread: 0
2009-08-25 00:03:23-0700 [Notification,client] Inbox-URL: /cgi-bin/HoTMaiL
2009-08-25 00:03:23-0700 [Notification,client] Folders-URL: /cgi-bin/folders
2009-08-25 00:03:23-0700 [Notification,client] Post-URL: http://www.hotmail.com
2009-08-25 00:03:23-0700 [Notification,client]

我们可以看到服务器正在向客户端发送一条消息，该消息指定了该帐户的未读电子邮件数量。

希望有帮助！

The method gotMessage claims to not be implemented. That likely means that you have subclassed a class that needs gotMessage to be overridden in the subclass, but you haven't done the overriding.
