無法使用 smack-Android 在 openfire 中創建新用戶

Question

我正在嘗試使用 smack 為 android 的即時消息應用程序創建一個新用戶，該用戶將存儲在 openfire 數據庫中，但每次我運行它時，用戶記錄都沒有顯示在 openfire 中

創建用戶活動

 private void setConnection() {

        // Create the configuration for this new connection

        //this function or code given in official documention give an error in openfire run locally to solve this error
        //first off firewall
        //then follow my steps

        new Thread() {
            @Override
            public void run() {

                InetAddress addr = null;
                try {
                    // inter your ip4address now checking it
                    addr = InetAddress.getByName("192.168.23.150");
                } catch (UnknownHostException e) {
                    e.printStackTrace();
                }
                HostnameVerifier verifier = new HostnameVerifier() {
                    @Override
                    public boolean verify(String hostname, SSLSession session) {
                        return false;
                    }
                };
                DomainBareJid serviceName = null;
                try {
                    serviceName = JidCreate.domainBareFrom("localhost");
                } catch (XmppStringprepException e) {
                    e.printStackTrace();
                }
                XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
                        .setUsernameAndPassword("admin","kalaBOOK98")
                        .setPort(9090)
                        .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
                        .setXmppDomain(serviceName)
                        .setHostnameVerifier(verifier)
                        .setHostAddress(addr)
                        .setDebuggerEnabled(true)
                        .build();
                Log.v(TAG,"connection configured");
                mConnection = new XMPPTCPConnection(config);
                        //now send message and receive message code here
                        AccountManager accountManager = AccountManager.getInstance(mConnection);
                        try {
                            Log.v(TAG,"Creating new user");
                            accountManager.createAccount(Localpart.from(userId),userPassword);
                        } catch (SmackException.NoResponseException e) {
                            Log.v(TAG,"Error in creating user"+e);
                            e.printStackTrace();
                        } catch (XMPPException.XMPPErrorException e) {
                            Log.v(TAG,"Error in creating user"+e);
                            e.printStackTrace();
                        } catch (SmackException.NotConnectedException e) {
                            Log.v(TAG,"Error in creating user"+e);
                            e.printStackTrace();
                        } catch (InterruptedException e) {
                            Log.v(TAG,"Error in creating user"+e);
                            e.printStackTrace();
                        } catch (XmppStringprepException e) {
                            Log.v(TAG,"Error in creating user"+e);
                            e.printStackTrace();
                        }
                    }

// Now we create the account:

// The account has been created, so we can now login

        }.start();
    }

每次我嘗試運行它時都會出現此日志錯誤

任何幫助將不勝感激提前致謝

Answer 1

正如您在日志中看到的，您必須連接到服務器才能創建新用戶。 您的連接有問題，在重新連接成功之前您無法創建用戶。 您可以通過以下方法在創建用戶之前檢查您的連接或身份驗證狀態：

connection.isAuthenticated()
connection.isConnected()

Answer 2

mConnection = new XMPPTCPConnection(config);
//now send message and receive message code here
AccountManager accountManager = AccountManager.getInstance(mConnection);
try {
    accountManager.createAccount(Localpart.from(userId),userPassword);
} …

創建連接實例后，它未連接。 這就是為什么當您嘗試執行需要連接的操作時會收到NotConnectedException原因。 為了在您的 XMPP 服務上創建帳戶，您首先必須通過調用連接到服務

`mConnection.connect()`.
