There may be a silly mistake and easy solution. 可能存在一个愚蠢的错误和简单的解决方案。 I googled but somehow I am not getting the right solution.
我用谷歌搜索,但不知何故,我没有得到正确的解决方案。
public void connectAndLogin( {
connect();
login();
}
private void connect() {
/**
* Set server configuration
*
* connect to server
*/
setConfiguration();
try {
getConnection().connect();
} catch (XMPPException e) {
e.printStackTrace();
setConnection(null);
}
}
private void setConfiguration() {
ConnectionConfiguration config = new ConnectionConfiguration(Constants.IP);
SmackConfiguration.setPacketReplyTimeout(Constants.PACKET_TIME_OUT);
System.out.println(SmackConfiguration.getVersion());
config.setRosterLoadedAtLogin(false);
// config.setCompressionEnabled(true);
config.setVerifyChainEnabled(false);
config.setReconnectionAllowed(true);
config.setSASLAuthenticationEnabled(false);
config.setSecurityMode(SecurityMode.disabled);
config.setDebuggerEnabled(false);
connection = new XMPPConnection(config);
}
private void login() {
if(getConnection()!=null){
String USER_NAME="";
String PASSWORD="";
try {
getConnection().login(USER_NAME,PASSWORD, Constants.RESOURCE);
} catch (Exception e) {
e.printStackTrace();
}
}
}
尝试使用端口5222而不是5223.这是旧的SSL方式,通常不再使用。
