android - 无法将 aSmack 客户端与我在 Android 中的 ejabberd2 服务器连接

Question

我使用 XMPP 创建一个聊天应用程序:

为此，我在我的 Android 应用程序中使用 eJabberd2 作为服务器，使用 asmack 库 (asmack-2010.05.07.jar) 作为客户端，

我可以连接到主机 talk.google.com 但无法连接到我的 eJabberd 主机。

我的代码是:

1) 工作正常:

    @Override
protected Void doInBackground(Void... arg0) {
    ConnectionConfiguration cc = new ConnectionConfiguration( "talk.google.com", 5222, "gmail.com" );
          XMPPConnection connection = new XMPPConnection(cc);
    try {
           SASLAuthentication.supportSASLMechanism("PLAIN");
                 cc.setSASLAuthenticationEnabled(true);
           connection.connect();    
           Roster.setDefaultSubscriptionMode(Roster.SubscriptionMode.manual);
                 Log.i("XMPPClient", "[SettingsDialog] Connected to "
                            + connection.getHost());

    } catch (XMPPException e1) {
        Log.e("XMPPClient", e1.toString());
      }
 }

2) 不工作: 我的 eJabberd 在 http://68.178.255.136:5280/admin/

@Override
protected Void doInBackground(Void... arg0) {
    ConnectionConfiguration cc = new ConnectionConfiguration( "68.178.255.136", 5280, "68.178.255.136" );
          XMPPConnection connection = new XMPPConnection(cc);
    try {
           SASLAuthentication.supportSASLMechanism("PLAIN");
                 cc.setSASLAuthenticationEnabled(true);
           connection.connect();    
           Roster.setDefaultSubscriptionMode(Roster.SubscriptionMode.manual);
                 Log.i("XMPPClient", "[SettingsDialog] Connected to "
                            + connection.getHost());

    } catch (XMPPException e1) {
        Log.e("XMPPClient", e1.toString());
      }
 }

Answer 1

我认为问题出在您提供的端口上，请使用 5222 而不是 5280，因为在 XMPP 中，客户端连接的是 5222 而不是 5280。
