Smack android 传入的 onStanza 与调试器不同

Question

windows 上的 Gajim 客户端和 smack debbuger return 这种节，与 xmpp 规范中的相同。

<message id='aeb213' to='juliet@capulet.lit/chamber'>
  <result xmlns='urn:xmpp:mam:2' queryid='f27' id='28482-98726-73623'>
    <forwarded xmlns='urn:xmpp:forward:0'>
      <delay xmlns='urn:xmpp:delay' stamp='2010-07-10T23:08:25Z'/>
      <message xmlns='jabber:client' from="witch@shakespeare.lit" to="macbeth@shakespeare.lit">
        <body>Hail to thee</body>
      </message>
    </forwarded>
  </result>
</message>

然而在 onStanza 中它 return 是这个：

<message to="juliet@capulet.lit/chamber" from="juliet@capulet.lit/chamber">
  <result xmlns="urn:xmpp:mam:0">
    <body>Hail to thee</body>
    <stanza-id/>
    <delay/>
    <archived/>
    <data/>
  </result>
</message>

你如何解决这个问题？这是部分代码。

public class XmppServiceSmackImpl implements XmppService, StanzaListener, ConnectionListener {
    XmppServiceListener xmppServiceListener;
    Logger logger = Logger.getLogger(XmppServiceSmackImpl.class.getName());

    XMPPTCPConnection connection;
    String password;

    public XmppServiceSmackImpl(XmppServiceListener xmppServiceListener) {
        this.xmppServiceListener = xmppServiceListener;
    }

    @Override
    public void setup(String jid, String password, String authMethod, String hostname, Integer port) {
        final String[] jidParts = jid.split("@");
        String[] serviceNameParts = jidParts[1].split("/");
        String serviceName = serviceNameParts[0];

        XMPPTCPConnectionConfiguration.Builder confBuilder = XMPPTCPConnectionConfiguration.builder()
                .setServiceName(serviceName)
                .setUsernameAndPassword(jidParts[0], password)
                .setConnectTimeout(3000)
                //.setDebuggerEnabled(true)
                .setSecurityMode(ConnectionConfiguration.SecurityMode.required);

        if (serviceNameParts.length>1){
            confBuilder.setResource(serviceNameParts[1]);
        } else {
            confBuilder.setResource(Long.toHexString(Double.doubleToLongBits(Math.random())));
        }
        if (hostname != null){
            confBuilder.setHost(hostname);
        }
        if (port != null){
            confBuilder.setPort(port);
        }
        if (trustedHosts.contains(hostname) || (hostname == null && trustedHosts.contains(serviceName))){
            confBuilder.setCustomSSLContext(UnsafeSSLContext.INSTANCE.getContext());
        }
        XMPPTCPConnectionConfiguration connectionConfiguration = confBuilder.build();
        XMPPTCPConnection.setUseStreamManagementDefault(true);
        XMPPTCPConnection.setUseStreamManagementResumptionDefault(true);
        connection = new XMPPTCPConnection(connectionConfiguration);

        // Disable automatic roster request
        Roster roster = Roster.getInstanceFor(connection);
        roster.setRosterLoadedAtLogin(false);
        roster.setSubscriptionMode(Roster.SubscriptionMode.manual);

        connection.addAsyncStanzaListener(this, null);
        connection.addConnectionListener(this);
        connection.addStanzaAcknowledgedListener(this);
    }

    @Override
    public void processPacket(Stanza packet) throws SmackException.NotConnectedException {
        logger.log(Level.WARNING, "Received stanza: " + packet);
        this.xmppServiceListener.onStanza(packet);
      }
}

属于 XEP-0280 在 SMACK 中，这是一项实验性功能。您的 build.gradle

中需要额外的库

dependencies {
    compile "org.igniterealtime.smack:smack-android-extensions:4.2.0"
}

在使用 SMACK 做任何事情之前，您必须初始化实验性功能：

new ExperimentalInitializer().initialize();

顺便说一下，provider 是一个类似插件的节处理程序当您想在客户端和服务器之间使用自定义节时。您必须编写自己的提供程序以将其解析为 Message 对象下的扩展元素。看看 ProviderManager。
