【问题描述】：

我正在尝试让 TLS XMPP 客户端在 Ubuntu 14.04 上使用 python 2.7.6 工作。我启用了调试模式，整个连接看起来都很好，直到我收到错误消息error Failed SASL authentification: <incorrect-encoding />。我已经通过桌面 Jabber 客户端验证了用户和密码帐户。这是我正在使用的代码。任何想法为什么这不起作用？：

#!/usr/bin/python

import xmpp

username= 'testxmpp'
passwd  = 'testtesttest'
to='jabber.somedomain.com'
msg='hello :)'



client = xmpp.Client('jabber.somedomain.com')
client.connect(server=('jabber.somedomain.com',5222))
client.auth(username, passwd, 'botty')
client.sendInitPresence()
message = xmpp.Message(to, msg)
message.setAttr('type', 'chat')
client.send(message)

这是程序调试输出的摘录：

      </failure>

【参考方案1】：

如果它对其他人有帮助，必须在 /usr/lib/python2.7/dist-packages/xmpp/auth.py 文件中进行编辑：

...
      elif "PLAIN" in mecs:
            sasl_data='%s\x00%s\x00%s'%(self.username+'@'+self._owner.Server,self.username,self.password)
            # ko - 2017-01-09 - fix for 'incorrect-encoding' error 
            # node=Node('auth',attrs='xmlns':NS_SASL,'mechanism':'PLAIN',payload=[base64.encodestring(sasl_data)])
            node=Node('auth',attrs='xmlns':NS_SASL,'mechanism':'PLAIN',payload=[base64.encodestring(sasl_data).replace('\r','').replace('\n','')]) 
        else:
