SleekXMPP send a message at will and still listen for incoming messages.

Question

I am trying to modify the sleekxmpp echobot example to act more like a client. I am able to receive and print messages with the code below but how do I make the code also allow me to send messages to another JID at will and not as an auto response to a message received. I am relatively new to python so any help will be very useful THANK YOU.

I have figure out this problem. this problem can use xmlstream._start_thread to fix. but it still a litte ugly.

Answer 2

The answer to your question is given in the "sign in, send, logout" tutorial. The main changes to the standard EchoBot code you posted are that you

• do not register a method for incoming messages and

• call send_message in the start function:

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

obviously, you're not limited to the start function; you can call this function at any point in your program when you want to send a message.
