我有这个 Android 应用程序,我一直在尝试设置 XMPP MultiUserChat。
至于连接到 XMPP,登录并创建一个 MUC(以及加入一个已经创建的)一切都很好。
我似乎无法正确收听发送的消息,我不知道为什么。
我之前曾使用过几次使用 Javascript 的 XMPP(带有 Bosh 的 StropheJS),所以我对它的协议有点熟悉。
正如我已经尝试过以下帖子中的建议(我发现的关于此事的唯一帖子):
如何在 Smack 中正确收听 MultiUserChat?
所以,我决定问你一些方向,因为我认为这可能只是我一直错过的一个设置。
所以,为了简单起见,我将提供我的整个序列。
我创建了一个服务,因此我的 XMPP 连接可以在整个应用程序中普遍存在。因为我需要在我的应用程序登录后立即连接到 XMPP,并且 MUC 房间只会在其他活动中进一步使用。好吧,你明白了。所以,这里是代码:
(对不起,如果它有点太长了,我并不是要烦人,我只想提供解决问题所需的一切)
//everything is alright here.
//it's connecting correctly to XMPP
public void connect()
{
Thread t = new Thread(new Runnable() {
@Override
public void run()
{
boolean flConnected = false;
System.setProperty("smack.debugEnabled", "true");
SmackConfiguration.setDefaultPacketReplyTimeout(10000);
ConnectionConfiguration ConnectionConfiguration = new ConnectionConfiguration(Host, Port);
ConnectionConfiguration.setSecurityMode(org.jivesoftware.smack.ConnectionConfiguration.SecurityMode.disabled);
ConnectionConfiguration.setDebuggerEnabled(true);
ConnectionConfiguration.setSendPresence(true);
connection = new XMPPTCPConnection(ConnectionConfiguration);
try
{
connection.connect();
login();
}
//there are many exceptions being treated, I
//suppressed them here for simplicity's sake
catch (Exception e)
{
Log.e(TAG, "connection exception: " + e.getMessage());
}
}
});
t.start();
}
public void login()
{
try
{
connection.login(this.User, Pwd);
Presence presence = new Presence(Presence.Type.available);
connection.sendPacket(presence);
this.setLoginAttempts();
}
catch (Exception e)
{
Log.e(TAG, "connection exception: "+e.getMessage());
}
}
因此,当用户应该是某个聊天组的管理员时,我创建传递 GroupName (id) 的组
public void createGroup(String strRoom)
{
try
{
muc = new MultiUserChat(connection, strRoom+"@"+this.GroupChat);
muc.create(this.User);
Form form = muc.getConfigurationForm();
Form submitForm = form.createAnswerForm();
for (Iterator fields = form.getFields().iterator(); fields.hasNext();) {
FormField field = (FormField) fields.next();
if (!FormField.TYPE_HIDDEN.equals(field.getType())
&& field.getVariable() != null) {
submitForm.setDefaultAnswer(field.getVariable());
}
}
List<String> owners = new ArrayList<>();
owners.add(this.User + "@"+this.Host);
muc.sendConfigurationForm(submitForm);
//here, it's another FAILED attempt of putting the
//listener to an async class. Didn't work at all!!
//just kept it here so you can see my attempts!
//new MessageRunner().execute(connection);
}
catch (Exception ex)
{
Log.e(TAG, " exception :"+ex.getMessage());
}
}
当它只是一个参与者时,它会加入该组:
public void joinGroup(String strRoom)
{
try
{
DiscussionHistory history = new DiscussionHistory();
history.setMaxStanzas(50);
muc = new MultiUserChat(connection, strRoom+"@"+this.GroupChat);
muc.join(strRoom, this.Pwd, history, connection.getPacketReplyTimeout());
this.addMessageListener(muc);
this.listen2Group();
}
catch (Exception ex)
{
Log.e(TAG, "Exception :"+ex.getMessage());
}
}
因此,我使用了 3 种方法来尝试让用户正确收听传入的消息。
其中之一是在登录后立即设置: setListener(connection);
其他两个在用户加入群聊后被调用:
addMessageListener(muc); 和listen2Group();
我把它们都留在这里,这样你就可以看到我走了多远:
private void addMessageListener(MultiUserChat muc)
{
//it's never coming here! never ever!!!
if(null != muc){
muc.addMessageListener(new PacketListener() {
@Override
public void processPacket(Packet packet) {
Log.i("processPacket", "receiving message");
}
});
}
}
private void listen2Group()
{
//also, NEVER EVER getting here at any time!!
PacketFilter filter = new MessageTypeFilter(Message.Type.groupchat);
connection.addPacketListener(new PacketListener() {
@Override
public void processPacket(Packet packet) throws NotConnectedException
{
Message message = (Message) packet;
if (message.getBody() != null)
{
//message should be treated here,
//but I suppressed it as well.
}
}
}, filter);
}
public void setListener(XMPPConnection cnx)
{
this.connection = cnx;
if (connection != null) {
PacketFilter filter = new MessageTypeFilter(Message.Type.groupchat);
connection.addPacketListener(new PacketListener() {
@Override
public void processPacket(Packet packet) {
Message message = (Message) packet;
if (message.getBody() != null)
{
//message will be treated here.
}
}
}, filter);
}
}
这是我发送消息的方式:
public void sendMessage(String msgText)
{
try
{
Message msg = new Message();
msg.setBody(msgText);
msg.setType(Message.Type.groupchat);
muc.sendMessage(msg);
//I tried sending with this one as well, nope!
//connection.sendPacket(msg);
}
catch(Exception ex)
{
Log.e(TAG, " exception :"+ex.getMessage());
}
}
所以,可能你已经看到我做错了。但我已经为此工作了好几天。什么都没有通过!
当我检查我的服务器( openfire )时,所有用户都被设置为在线,并且正在正确登录到 MUC,当消息发送时,没有任何反应!
我在我展示给你的所有侦听器上都设置了断点,但无论我做什么,它们都不会触发。消息已发送,但它永远不会到达任何地方。
有任何想法吗?
