我正在开发一个聊天应用程序，但它不能正常工作，给出不同的错误，如 406 或 407，所以请告诉我我的以下代码是否正确，
应用程序启动时首次登录：
public void LoginWithUser() {
Thread t = new Thread(new Runnable() {
@Override
public void run() {
SASLAuthentication.unregisterSASLMechanism("org.jivesoftware.smack.sasl.javax.SASLDigestMD5Mechanism");
SmackInitialization initialization = new SmackInitialization();
XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();
config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
config.setServiceName(Constants.SERVICE);
config.setHost(Constants.HOST);
config.setPort(Constants.PORT);
config.setResource("myresource");
config.setDebuggerEnabled(true);
config.setKeystoreType("AndroidCAStore");
config.setConnectTimeout(100000);
try {
config.setUsernameAndPassword(getUserName(), password);
} catch (Exception e) {
e.getMessage();
}
Constants.connection = new XMPPTCPConnection(config.build()); //new XMPPConnection(Constants.connConfig);
try {
if (!Constants.connection.isConnected()) {
Constants.connection.connect();
}
Log.i("ChatActivity", "Connected to "
+ Constants.connection.getHost());
} catch (XMPPException ex) {
Log.e("ChatActivity",
"Failed to connect to " + Constants.connection.getHost());
Log.e("ChatActivity", ex.toString());
// setConnection(null);
} catch (IOException | SmackException e) {
e.printStackTrace();
Log.e("my error outer", e.getMessage() + " <- Understand 0 ? !!!");
}
try {
Log.d("chat : user name", getUserName());
try {
Log.d("chat : password", AESCrypt.decrypt(Constants.key_store_pair, enc_login_key));
} catch (Exception e) {
e.printStackTrace();
}
try {
SASLAuthentication.blacklistSASLMechanism("SCRAM-SHA-1");
Constants.connection.login(getUserName(), password);
Constants.connection.getServiceName();
Log.d("service name=", Constants.connection.getServiceName());
} catch (Exception e) {
e.printStackTrace();
Log.e("my error inner", e.getMessage() + " <- Understand 1 ? !!!");
}
Log.i("ChatActivity", "Logged in as "
+ Constants.connection.getUser());
Log.i("You are valid user",
"your Token is " + Constants.connection.getUser());
} catch (Exception ex) {
}
}
});
t.start();
}
它连接成功...
在我创建新会议室之后，我通过调用以下方法注册该会议室：
private MultiUserChat createGroupChat(XMPPConnection connection,String room_id, String groupName, String registered_beam_iddd) throws XMPPException, SmackException {
// This code call when creating new conference room
Constants.mucM = MultiUserChatManager.getInstanceFor(connection); //new MultiUserChatManager(connection, registered_beam_iddd + "@" + groupName);
Constants.muc = Constants.mucM.getMultiUserChat(registered_beam_iddd + "@" + groupName);
if(Constants.connection.isConnected())
{
if(Constants.connection.isAuthenticated()) {
Constants.muc.createOrJoin(room_id + "@" + groupName); //
Form form = Constants.muc.getConfigurationForm();
Form submitForm = form.createAnswerForm();
Constants.muc.sendConfigurationForm(submitForm);
Log.d("Room Created : Name : " , room_id + "@" + groupName);
}
else
{
//Toast.makeText(getActivity(),"Authenicated false",Toast.LENGTH_LONG).show();
Log.d("ooo", "authentication failed in AddBeam");
}
}
else
{
Toast.makeText(getActivity(),"Connection Loss",Toast.LENGTH_LONG).show();
}
return Constants.muc;
//onesecond
}
当我点击会议室号码（列表视图）时，这意味着当我进入我的任何会议室时，我会调用以下方法加入会议室并获取历史记录，
private MultiUserChat joinGroupChat(XMPPConnection connection, String room_id, String groupName, String registered_beam_iddd) throws XMPPException, SmackException {
// This code called when user enter in Chat-conference room
if (Constants.connection.isConnected()) {
if (Constants.muc == null) {
Constants.mucM = MultiUserChatManager.getInstanceFor(connection); //new MultiUserChatManager(connection, registered_beam_iddd + "@" + groupName);
Constants.muc = Constants.mucM.getMultiUserChat(registered_beam_iddd + "@" + groupName);
}
if (Constants.connection.isAuthenticated()) {
if (!Constants.muc.isJoined()) {
DiscussionHistory history = new DiscussionHistory();
history.setMaxStanzas(20);
Constants.muc.join(room_id + "@" + groupName, "password", history, Constants.connection.getPacketReplyTimeout()); // @conference.tubsystems.com
} else {
Log.d("joined: ", room_id + "@" + groupName);
}
} else {
Log.d("ooo", "authentication failed in AddBeam");
}
} else {
Toast.makeText(getApplicationContext(), "Connection Loss", Toast.LENGTH_LONG).show();
try {
Constants.connection.connect();
Log.i("ChatActivity", "Connected to "
+ Constants.connection.getHost());
} catch (Exception ex) {
Log.e("ChatActivity",
"Failed to connect to " + Constants.connection.getHost());
Log.e("ChatActivity", ex.toString());
// setConnection(null);
}
}
return Constants.muc;
//onesecond
}
对于向会议发送消息：
private void sendmessage(String text, String room) {
String to = beamId + "@"+groupname;
Message msg = new Message(to, Message.Type.groupchat);
msg.setBody(text);
if (Constants.connection != null) {
try {
Constants.connection.sendPacket(msg);
Log.d("Send to room : Name : ", to);
} catch (Exception e) {
Log.d("ooo", "msg exception" + e.getMessage());
}
messages.add(text);
msg_send_receive_val = 1;
new setListAdapter().execute();
}
}
但是它有时会出现连接错误，有时会出现406或407错误，当我当时第一次进入会议室时，它只会显示过去的历史消息，然后自动删除，并且消息也有时不发送，有时发送，我不知道是什么问题，在发送消息时它给出 406-407 修改 - 不可接受的错误，有时会给出其他错误。
我不知道上面的代码中是否缺少任何内容，或者配置会议室所需的任何其他内容？请尽快帮助我。
提前致谢。
