发送和接收的智商XMPP ASMACK的Andr​​oid [英] Send and Receive IQ XMPP ASMACK Android

问题描述

背景：

我已经能够实现一对一的使用 asmack 库通过 XMPP Android中聊天。我能送presence到服务器上。我使用的Openfire 服务器基于我的聊天应用程序。

I have been able to implement one to one chatting through XMPP in android using asmack library. I am able to send presence to the server as well. I am using OpenFire server for my Chat based application.

问题：
我使用 connection.addPacketListener（新PacketListener（）来接收消息和智商的数据包，因为我已经把它归类这样的消息包

Problem: I am using connection.addPacketListener(new PacketListener() to receive message and IQ packets, for message packets I have classified it like this

PacketFilter Chatfilter = new MessageTypeFilter(Message.Type.chat);
connection.addPacketListener(new PacketListener() {
        public void processPacket(Packet packet) {
            Message message = (Message) packet;
            if (message.getBody() != null) {
                String fromName = StringUtils.parseBareAddress(message.getFrom());
                Log.i("XMPPClient", "Got text [" + message.getBody() + "] from [" + fromName + "]");
                messages.add(fromName + ":");
                m1=message.getBody();
                messages.add(message.getBody());
                // Add the incoming message to the list view
                /* mHandler.post(new Runnable() {
                public void run() {
                setListAdapter();
                recieve.setText(m1);
                }
                });*/
            }
        }
}, Chatfilter);

和它工作一切正常，但当我用类似的东西来接收数据包智商的出现问题

And it is working all fine, but problem arises when I use something similar to receive IQ packets

下面是code，我现在用的接收IQ PACKETS

Here is the code which I am using to receive IQ PACKETS

PacketFilter Iqfilter = new IQTypeFilter(IQ.Type.RESULT);
connection.addPacketListener(new PacketListener() {
    public void processPacket(Packet packet) {
        IQ iq = (IQ) packet;
        String fromName = StringUtils.parseBareAddress(iq.getFrom());
        Log.i("XMPPClient", "Got text [" + iq.toString() + "] from [" + fromName + "]");
        m1=iq.getFrom();
        mHandler.post(new Runnable() {
            public void run() {
                setListAdapter();
                recieve.setText(m1);
            }
        });
    }
}, Iqfilter);

我发送一个简单的迪斯科＃项目查询，并没有作出回应，甚至不进入的功能，我试图调试它，以及，我也试图发送简单 PING 命令，但它并没有给它要么回应。 什么我在这里丢失？

I am sending a simple disco#items query and it does not respond, even it does not enter into the function, I have tried to debug it as well, I have also tried to send simple PING command but it does not respond to it either. what am I missing here?

其次，我的智商发送数据包到服务​​器，以及或其他一些客户面临的问题也是如此。我读的地方，我不喜欢这样。但它不工作

Secondly I am facing problems in sending IQ packets to the server as well or to some other client as well. I read somewhere that I should do it like this. but it does not work.

final IQ iq = new IQ() {
            public String getChildElementXML() { 
            return "<query xmlns='http://jabber.org/protocol/disco#info'/>"; // here is your query
            //this returns "<iq type='get' from='User@YourServer/Resource' id='info1'> <query xmlns='http://jabber.org/protocol/disco#info'/></iq>";
             }};
            // set the type
            iq.setType(IQ.Type.GET);

            // send the request
            connection.sendPacket(iq);

混乱的事情是，当我读到的XMPP为Android有人写了送你需要有接收器的地址以及智商的文档和asmack。但在这个code，我们不设置任何接收器。

The confusing thing is when I read the documentation of XMPP and asmack for android it was written that to send an IQ you need to have receiver's address as well. but in this code we are not setting up any receiver.

有对XMPP asmack和Android互联网上提供很少的信息。

There is much less information available on internet for XMPP asmack and Android.

推荐答案

我认为问题是，你的供应商没有注册。请看看这个。在Android上你有你形成一个XMPP连接之前手动注册供应商。下面的类复制到项目

I think the problem is that your providers aren't registered. Please take a look at this. On Android you have to register the providers manually before you form an XMPP connection. Copy the class below into your project

调用此方法像这样

Call this method like this

ServiceProviders.Register_Providers(ProviderManager.getInstance());

于是尝试调用你的应用程序的开始或形成连接之前，此方法。

So try calling this method at the start of your app or before forming a connection.
