Question

还有其他问题相同，但没有一个问题具有明确的功能。我试图通过python-xmpp发送聊天消息：

import xmpp

username = 'test@server.com'
passwd = 'password'
to='test2@server.com'
msg='hello :)'


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

但是我不明白返回的错误：

我可以看到我成功连接到服务器，但之后就没有意义了。我怀疑客户端= xmpp.Client（'Adium'）中的“客户端”存在问题，但不确定应该去哪里或者甚至是问题。你觉得怎么样？

我在python 2.7上使用python-xmpp并想知道这是不兼容的还是什么。

在你的代码中你有这一行：

client = xmpp.Client('Adium')

应该是：

client = xmpp.Client('server.com')

此处的参数是您要连接的XMPP主机。因为＆＃39; Adium＆＃39;不是服务器上可识别的主机，它根据您的日志返回主机未知错误：

   <stream:error>
   <host-unknown xmlns='urn:ietf:params:xml:ns:xmpp-streams'/>
   </stream:error>

更好的方法是重写您的登录代码：

import xmpp

jid = xmpp.protocol.JID('test@server.com')
passwd = 'password'
to='test2@server.com'
msg='hello :)'

client = xmpp.Client(jid.getDomain())
client.connect()
client.auth(jid.getNode(), passwd, 'botty')

现在只有一个jid变量包含您的XMPP地址（简称为Jabber ID＆＃39;或简称JID）。 jid.getDomain()返回服务器部分，jid.getNode()返回JID的用户部分。

我还从client.connect()删除了主机和端口的手动规范。如果您的服务器和DNS配置正确，则不需要这些。
