如何使用UserSearchManager检查用户是否已在xmpp中注册？

Question

我已经开始开发聊天应用程序。 我需要检查用户是否已在xmpp服务器中注册。因此，当用户尝试注册时，我要检查用户是否已在xmpp服务器中注册。 xmpp服务器成功连接后，尝试使用Usersearchmanager作为号码进行搜索。

Answer 1

您要查找的字符串必须是JID，而不是用户名：

您需要类似：

user1@myserver

而不仅仅是

user1

然后，在您的用例中检查JID完全没有用。

Answer 2

我已经在smack 4.1上使用以下代码注册用户：-

   //Login User
   public XMPPTCPConnection loginUser(Context objContext, XMPPTCPConnection objXmpptcpConnection, String strUsername, String strPassword) {

       try {
           AccountManager objAccountManager = AccountManager.getInstance(objXmpptcpConnection);
           objAccountManager.createAccount(strUsername, strPassword);
           objXmpptcpConnection = loginToServer(objXmpptcpConnection, strUsername, strPassword);
       } catch (SmackException | XMPPException e) {

           System.out.println("Msg=" + e.getMessage() + "\nCause =" + e.getCause() + "\n Local msg=" + e.getLocalizedMessage() + "\n stack=" + e.getStackTrace() + "\n class " + e.getClass());
           System.out.println("Code=" + e.getStackTrace()[0].getLineNumber());
           if (e.getMessage().contains("conflict")) {
               objXmpptcpConnection = loginToServer(objXmpptcpConnection, strUsername, strPassword);
           }
       }
       return objXmpptcpConnection;
   }

   private XMPPTCPConnection loginToServer(XMPPTCPConnection objXmpptcpConnection, String strUsername, String strPassword) {

       try {
           objXmpptcpConnection.login(strUsername + "@" + AppConstants.HOST, strPassword, "example");
          // objXmpptcpConnection.sendPacket(new Presence(Presence.Type.unavailable));
//objXmpptcpConnection.sendPacket(new Presence(Presence.Type.available));
       } catch (XMPPException e) {
           e.printStackTrace();
       } catch (SmackException e) {
           e.printStackTrace();
       } catch (IOException e) {
           e.printStackTrace();
       }
       Log.i("XMPPChatDemoActivity", "Logged in as "
               + objXmpptcpConnection.getUser());
       Toast.makeText(
               objContext,
               "log in as "
                       + objXmpptcpConnection.getUser(),
               Toast.LENGTH_SHORT).show();

       return objXmpptcpConnection;
   }

使用以上两种方法成功注册用户到ejabberd。

和连接方法是：-

public XMPPTCPConnection connect(String strUsername, String strPassword) throws IOException, XMPPException, SmackException {
    objXmpptcpConnection = null;
    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }
    // Create a connection
    XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();
    config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
    config.setServiceName(Constants.HOST);
    config.setPort(Constants.PORT);
    config.setHost(Constants.HOST);
    config.setDebuggerEnabled(true);
    config.setSendPresence(true);
    config.setUsernameAndPassword(strUsername + "@" + Constants.HOST, strPassword);


    SASLAuthentication.blacklistSASLMechanism("SCRAM-SHA-1");
    SASLAuthentication.blacklistSASLMechanism("DIGEST-MD5");
    SASLAuthentication.unBlacklistSASLMechanism("PLAIN");
    objXmpptcpConnection = new XMPPTCPConnection(config.build());
    objXmpptcpConnection.setUseStreamManagement(true);
    objXmpptcpConnection.setUseStreamManagementResumption(true);
    try {
        ProviderManager objProviderManager = new ProviderManager();
        ProviderManager.addExtensionProvider(DeliveryReceipt.ELEMENT, DeliveryReceipt.NAMESPACE, new DeliveryReceipt.Provider());
        ProviderManager.addExtensionProvider(DeliveryReceiptRequest.ELEMENT, new DeliveryReceiptRequest().getNamespace(), new DeliveryReceiptRequest.Provider());
        ProviderManager.addIQProvider("query", "http://jabber.org/protocol/bytestreams", new BytestreamsProvider());
        ProviderManager.addIQProvider("query", "http://jabber.org/protocol/disco#items", new DiscoverItemsProvider());
        ProviderManager.addIQProvider("query", "http://jabber.org/protocol/disco#info", new DiscoverInfoProvider());

        //  Offline Message Requests
        objProviderManager.addIQProvider("offline", "http://jabber.org/protocol/offline", new OfflineMessageRequest.Provider());

        //  Offline Message Indicator
        objProviderManager.addExtensionProvider("offline", "http://jabber.org/protocol/offline", new OfflineMessageInfo.Provider());
        objXmpptcpConnection.connect();
        System.out.println("Connected to===>" + objXmpptcpConnection.getHost());
        objXmpptcpConnection.login();

        objDeliveryReceiptManager = DeliveryReceiptManager.getInstanceFor(objXmpptcpConnection);
        objDeliveryReceiptManager.autoAddDeliveryReceiptRequests();
        objDeliveryReceiptManager.setAutoReceiptMode(DeliveryReceiptManager.AutoReceiptMode.disabled);
        objDeliveryReceiptManager.addReceiptReceivedListener(this);

    } catch (XMPPException e) {
        e.printStackTrace();
        return objXmpptcpConnection;
    } catch (SmackException e) {
        e.printStackTrace();
        return objXmpptcpConnection;
    } catch (IOException e) {
        e.printStackTrace();
        return objXmpptcpConnection;
    }
    return objXmpptcpConnection;
}

另外，您还想检查ejabberd端的配置。

它为我工作的尝试使用答案： -Smack API用户搜索 。

希望它对您有用。
