Python XMPP简单客户端错误

Question

我遇到了以下错误：

AttributeError: Client instance has no attribute 'Dispatcher'

在Python 2.7中运行以下代码时：

import xmpp 

user= '[e-mail]'
password="pass"

jid = xmpp.JID(user) 
connection = xmpp.Client(jid.getDomain()) 
connection.connect() 
connection.auth(jid.getNode(),password)

如果有人知道如何修复它，我会很高兴。

P.S. 在 N3RO 提出修复建议之后，错误的完整回溯如下：

请包含完整的回溯跟踪以查找错误。 - Martijn Pieters

@Martijn Pieters。我做了。 - rok

AttributeError似乎是在连接由于超时而失败之后出现的问题。你是否在防火墙后面？ - Martijn Pieters

@Martijn Pieters。抱歉，我回复有些晚了。我已关闭Windows防火墙，但仍然遇到相同的错误。这台计算机连接到域网络。也许，仍有一种方法可以通过编程成功连接？在运行程序时运行wireshark，发现只发送了3个SYN消息到173.194.70.125，就像我使用Google Talk连接时一样，但是没有捕获到响应。 - rok

Answer 1

您需要指定要连接到的服务器。

connection.connect(server=('serveradress.com', portnumber))

修改后，我无法再现AttributeError错误。

我还建议您使用正确的JID来测试您的代码。JID类似于由@分隔的电子邮件地址，这就是为什么在您的示例代码中jid.getNode()返回空值的原因。

*我的代码示例更正如下：

import xmpp

user = '[e-mail]'
password = 'password'

jid = xmpp.JID(user)

connection = xmpp.Client(jid.getDomain())
connection.connect(server=('talk.google.com', 5223))
connection.auth(jid.getNode(), password)
connection.sendInitPresence()

谢谢。我仍然遇到错误，您可以在我编辑后的问题中看到完整的回溯信息。抱歉，在问题中已经修复了它。实际上，我的代码中确实有一个真正的JID。 - rok

我将我的可运行代码添加到了我的答案中。希望能对你有所帮助。 - N3RO

@ N3RO。谢谢，它在我家里运行正常，但连接到域网络的计算机上无法运行。 - rok

Answer 2

在您的追踪回溯中，看起来您正在尝试连接不存在的域名talk.gmail.com，因此connection.connect语句将无法打开连接。

尝试连接到talk.google.com，这可能是正确的服务器名称。
