Tobot@jabber.org

Der Chatbot ist wieder offline und war als Experiment zur Einarbeitung in Smack gedacht.

"Smack is an Open Source XMPP (Jabber) client library for instant messaging and presence. A pure Java library, it can be embedded into your applications to create anything from a full XMPP client to simple XMPP integrations such as sending notification messages and presence-enabling devices."

Jemand fragte mich auch nach dem Source-Code (tut mir leid, sehr hässlich ohne syntax-highlighting):

import org.jivesoftware.smack.*;
import org.jivesoftware.smack.packet.Message;

public class Smacko implements ChatManagerListener {
 public static void main(String[] args) throws XMPPException, IOException {
  new Smacko();
 }

 public Smacko() throws XMPPException, IOException {
  // open database with saved answers, names, etc.
  // Create the configuration for this new connection
  ConnectionConfiguration config = 
   new ConnectionConfiguration("jabber.org", 5222, "jabber.org");
  XMPPConnection connection = new XMPPConnection(config);
  connection.connect();
  SASLAuthentication.supportSASLMechanism("PLAIN", 0);
  connection.login("tobot", "nearly forgot to remove the password here");
  
  // prints all contacts
  // Roster roster = connection.getRoster();
  // Collection entries = roster.getEntries();
  
  System.out.println("\n\n" + entries.size() + " buddy(ies):");
  for(RosterEntry r:entries){
   System.out.println(r.getUser());
  }
  
  ChatManager chatmanager = connection.getChatManager();
  chatmanager.addChatListener(this);
  
  new Thread(){
   @Override 
   public void run() {
    while(true){
     try {
     Thread.sleep( 1000000 );
     System.out.print( "." );
     } catch ( InterruptedException e ) { e.printStackTrace(); }
    }
   }
  }.start();
 }
 
 @Override
 public void chatCreated(Chat chat, boolean arg1) {
  //System.out.println(chat.getParticipant());
  chat.addMessageListener(new MessageListener(){
   public void processMessage(Chat chat, Message message) {
       System.out.print(".");
          try {
     chat.sendMessage(answer(chat, message));
    } catch (XMPPException e) {
     System.out.println("Error Delivering block"+e.getMessage());
    }
      }
  });
 }
 
 public String answer(Chat chat, Message message){
  String text = message.getBody();
  if(text == null) return "Hi";
  // remove all regex-metachars and some 
  text = text.replaceAll("[\\[\\]\\(\\)\\{\\}\\|\\?\\+\\-\\*\\^\\$\\.!\"#%&',/:;<=>@_`~\\\\]", "");
  // restliche Antwortlogik
 }
 
}
