SleekXMPP可以随意发送消息，并且仍然可以监听传入的消息。

Question

我正在尝试修改sleekxmpp echobot示例，使其更像一个客户机。我可以用下面的代码接收和打印消息，但如何使代码也允许我随意发送消息到另一个JID，而不是作为对收到消息的自动响应。我对python比较陌生，所以任何帮助都非常有用，谢谢。

我已经解决了这个问题。这个问题可以用xmlstream.u start.u线程来解决。但还是有点难看。

您的问题的答案在“sign in, send, logout”教程中给出。您发布的标准EchoBot代码的主要更改是

• 不为传入消息注册方法，并且

• 在start函数中调用send_message：

  self.send_message(mto="some@jid", mbody="some message text")
  

显然，您不仅限于start函数；当您想发送消息时，可以在程序中的任何点调用此函数。
