無法連接到Openfire服務器（使用smack api）

Question

我試圖使用smack 4.1.0運行此代碼

 Thread D= new Thread(new Runnable() {

            @Override
            public void run() {
                SmackConfiguration.setDefaultPacketReplyTimeout(10000);
                XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
                        .setUsernameAndPassword("harsh", "pass")
                        .setServiceName("192.168.0.200")
                        .setHost("192.168.0.200")
                        .setPort(5223).setSecurityMode(ConnectionConfiguration.SecurityMode.ifpossible)
                        .build();

                AbstractXMPPConnection conn2 = new XMPPTCPConnection(config);
                try {
                    conn2.connect();

                    conn2.login();

                    Presence presence = new Presence(Presence.Type.unavailable);
                    presence.setStatus("Gone fishing");
                    // Send the packet (assume we have an XMPPConnection instance called "con").
                    conn2.sendStanza(presence);

                } catch (SmackException | IOException | XMPPException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                    Log.d("TAG", e.toString());
                }

                ChatManager chatmanager = ChatManager.getInstanceFor(conn2);


                Chat newChat = chatmanager.createChat("harsh@192.168.0.200");

                try {
                    newChat.sendMessage("Howdy!");
                }
                catch (SmackException.NotConnectedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }



            }
        });





        D.start();


    }

這給了我一個錯誤：

並且，在本地openfire服務器中啟用調試后，我收到以下消息：

2015.05.15 14:50:03 index.jsp - Failed to fetch RSS feed: javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: root certificate not trusted of [vanity2.jiveon.com]

我哪里錯了？

Answer 1

根據用戶問題的討論是在XMPPTCPConnectionConfiguration .Port 5223中的.setPort(5223)默認情況下Openfire中的客戶端SSL端口，

you can change this port setting in  Openfire 3.10 from Admin panel 

服務器>>服務器設置>>客戶端連接

錯誤

org.jivesoftware.smack.SmackException $ NoResponseException：在回復超時內沒有收到響應。 超時為10000毫秒（~10秒）。

意味着您正在嘗試連接啟用SSL的端口[5223]而不執行SASL協商。 意味着您需要在應用程序中存儲由XMPP服務器[Opnefire]提供的SSL證書[在您的內部/外部存儲器中的某些位置]，並使用相同的證書與SSL端口上的Xmpp服務器進行進一步通信。

對於SSL身份驗證，您可以使用Truststore
