如何将XMPP IQ包发送到PHP JAXL脚本？

我有一个问题。我使用asmack在Android和OpenFire之间连接和发送数据。

现在我想用PHP和Jaxl获取这些数据（工作正常）。

问题是我修改了发送的消息（到JSON和XML）并将HEADER添加到XML / JSON。这似乎运作良好，但它不是一个合适的解决方案。

现在我正在考虑发送包含Header信息的IQ包。

这是Android / Java中的部分。

      CommandIQPacket iq1 = new CustomIQPacket();
            iq1.setTo(to);
            iq1.setType(IQ.Type.GET);
            iq1.setCommand("test");
            iq1.setPriority(1);
            iq1.setJid(message.getMessage());
            iq1.setDate(new Date(System.currentTimeMillis()));
        mConnection.sendPacket(iq1);

CustomIQPacket类通过覆盖getChildElementXML（）来扩展IQ并添加所需的数据。

示例：

public class CommandIQPacket extends IQ {


private int priority;
private String jid, command;
//some getter and setter

@Override
public CharSequence getChildElementXML() {

    StringBuilder builder = new StringBuilder("<query xmlns=\"urn:xmpp:ts\">");
    builder.append("<jid command=\"");
    builder.append(command).append("\"");
    builder.append(" date=\"");
    builder.append(date).append("\"");
    builder.append(" priority=\"");
    builder.append(priority).append("\"");
    builder.append(">");
    builder.append(jid);
    builder.append("</jid>");
    builder.append("</query>");
    return builder.toString();

}

}

现在我使用JAXL获取了PHP CLI脚本。看起来就是这样。

 <?php

  // configs, stuff, etc. 

$client = new JAXL(array(
'jid' => "myopenfireuser",
'pass' => "myopenfirepass",
'bosh_url' => "http://url-to-bosh.com:7070/http-bind/",
'log_level' => JAXL_INFO,
'strict' => TRUE
    ));

$client->require_xep(array(
'0115', // Entity Capabilities
'0203', // Delayed Delivery
'0114', // jabber component protocol
'1337'
));

我在这里添加了1337，它应该是解析IQ包的XEP。

$client->add_cb('on_chat_message', function($stanza) {
global $client;

$iq = $client->xeps['1337']->get_raw_iq_pkt();
  // some more stuff
}

现在似乎$ iq没有任何rawdata。我无法访问XML，这意味着我无法解析IQ包。

1337 XEP看起来就是这样。

class XEP_1337 extends XMPPXep {

public function init() {
    return array(
        'on_get_iq' => 'on_xmpp_iq'
    );
}

public function get_raw_iq_pkt() {

    $attrs = array(
        'type' => 'get',
        'from' => $this->jaxl->full_jid->to_string(),
        'to' => $this->jaxl->full_jid->domain
    );

    return $this->jaxl->get_iq_pkt(
                    $attrs, new JAXLXml('query', "ts")
    );
} 
}

我找不到任何关于JAXL和IQ包的好教程。这是我发现的唯一自述文件（https://media.readthedocs.org/pdf/jaxl/latest/jaxl.pdf）

发送的数据例如是

 <iq id='qEfml-14' to='openfirebot@openfirebot.com/Ressource' type='get'><query xmlns="ts"><jid command="test" date="Mon Jul 28 12:36:15 MESZ 2014" priority="1">...</query></iq>

来自openfire（jaxl）的返回值是

<iq type="error" id="NP3HP-12" from="bot..@myopenfire.com" to="maclient@ts.com/Ressource"><query xmlns="ts" action="create"><jid command="test" date="Mon Jul 28 23:04:22 MESZ 2014" priority="1">...</jid></query><error code="503" type="cancel"><service-unavailable xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error></iq>

1 个答案:

答案 0 :(得分：0)

这就是我现在发现的：

Its important that to has the fullname with ressource.  user@domain/Ressource

并且..接收客户必须在线。来自OpenFire的IQ PAckets（默认情况下）不接受离线消息

并且..关于这篇文章，它必须以某种方式注册。怎么能在jaxl中完成？我认为添加XEP并使用init（）就足够了。     Sending and Receiving custom XMPP IQs with aSmack on Android

并且..我修改了PAcketListener但结果仍然相同。

        PacketFilter filter = new PacketFilter() {
            @Override
            public boolean accept(Packet packet) {
                return true;
            }
        };

        mConnection.addPacketListener(mPacketListener, filter);
        ProviderManager.addIQProvider("query", "ts", new CommandIQProvider());

而mPacketListener是一个从PacketListener扩展的类。

 public class ChatPacketListener implements PacketListener {

public void processPacket(Packet packet) {
    if (packet instanceof  Message) {
        Message message = (Message) packet;
        String from = message.getFrom();
        if (message.getBody() != null) {

            Log.d("ChatPacketLsitener", "XMPP packet received - sending Intent: " + XmppService.ACTION_XMPP_MESSAGE_RECEIVED);
            XmppService.maybeAcquireWakeLock();
            XmppTools.startSvcXMPPMsg(mCtx, message.getBody(), from);
        }
    } else {
        Log.e("Packet", "Packet is not from type Message. Its from type " + packet.getClass());

    }
}
