【问题描述】：

我想开发一个连接到 Google Talk 并允许用户与其朋友聊天的 Java 应用程序。我正在使用 smack API 和下面的代码：

ConnectionConfiguration config = new ConnectionConfiguration("talk.google.com",5222,"gmail.com");
SASLAuthentication.supportSASLMechanism("PLAIN", 0);
XMPPConnection connection  = new XMPPConnection(config);
try 
    connection.connect();
 catch (XMPPException e) 
    e.printStackTrace();

try 
    connection.login("username", "password");
 catch (XMPPException e) 
    e.printStackTrace();

但我得到了休闲异常：

SASL authentication PLAIN failed: invalid-authzid: 
    at org.jivesoftware.smack.SASLAuthentication.authenticate(SASLAuthentication.java:337)
    at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:203)
    at org.jivesoftware.smack.Connection.login(Connection.java:348)
    at Main.main(Main.java:21)

谁能帮我解决这个问题？

【参考方案1】：

这应该可以解决问题，非常简单

import org.jivesoftware.smack.Chat;
import org.jivesoftware.smack.ChatManager;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.MessageListener;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Message;
import org.jivesoftware.smack.packet.Presence;

 public class SenderTest 

public static void main(String args[])

    //ConnectionConfiguration connConfig = new ConnectionConfiguration("localhost", 5222);
        //connConfig.setSASLAuthenticationEnabled(false);
     //ConnectionConfiguration connConfig = new ConnectionConfiguration("localhost", 5222);
     ConnectionConfiguration connConfig = new ConnectionConfiguration("talk.google.com", 5222, "gmail.com");
       XMPPConnection connection = new XMPPConnection(connConfig);

        try 
            connection.connect();
            System.out.println("Connected to " + connection.getHost());
         catch (XMPPException ex) 
            //ex.printStackTrace();
            System.out.println("Failed to connect to " + connection.getHost());
            System.exit(1);
        
        try 
            connection.login("[e-mail]", "a");
            System.out.println("Logged in as " + connection.getUser());

            Presence presence = new Presence(Presence.Type.available);
            connection.sendPacket(presence);

         catch (XMPPException ex) 
            //ex.printStackTrace();
            System.out.println("Failed to log in as " + connection.getUser());
            System.exit(1);
        

    ChatManager chatmanager = connection.getChatManager();
    Chat newChat = chatmanager.createChat("[e-mail]", new MessageListener() 
        public void processMessage(Chat chat, Message message) 
            System.out.println("Received message: " + message);
        
    );

    try 
        newChat.sendMessage("Howdy!");
        System.out.println("Message Sent...");
    
    catch (XMPPException e) 
        System.out.println("Error Delivering block");
    

【参考方案2】：

这是我使用 smack 连接到 google talk 的方法。

 private ConnectionStatus status;
 private XMPPConnection xmppConnection;

public void connect(String server, int port, String s) throws Exception

xmppConnection = new XMPPConnection(new ConnectionConfiguration(server, port,s));
xmppConnection.connect();
xmppConnection.addConnectionListener(this);
xmppConnection.getChatManager().addChatListener(this); 

和身份验证。

public void authenticate(String username, String password) throws Exception

  xmppConnection.login(username, password);
buddyList.setSession(xmppConnection);
setStatus(ConnectionStatus.AUTHENITCATED);

【讨论】：

谢谢，我成功登录了，但由于某种原因，我得到了一个异常，我不知道如何发布它

可以登录但出现异常？能发第一行吗？

【参考方案3】：

这拯救了我的一天

connectionConfig = new ConnectionConfiguration(host, port, service);
connectionConfig.setSASLAuthenticationEnabled(false);
connectionConfig.setTruststoreType("BKS");
connection = new XMPPConnection(connectionConfig);
