Android（23）-Smack（4.1.8）-XMPP-“ SSL23_GET_SERVER_HELLO：未知协议”错误

Question

我正在尝试使用Smack 4.1.8库通过XMPP在Android（23）中构建聊天应用程序。 我正在直接在手机（Galaxy S6和Galaxy E7）上对此进行测试。 我正在尝试连接到xmpp.jp。 尝试连接时出现此异常：

使用本教程 。 我尝试了DummySSLSocketFactory ，[NoSSLFactory]和[TLSFactory]解决方案（无法发布两个以上的链接：|）。 他们都没有为我工作。

我的连接代码是：

private void initialiseConnection() {

    XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration
            .builder();
    //config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
    config.setSecurityMode(ConnectionConfiguration.SecurityMode.required);
    config.setServiceName(serverAddress);
    config.setHost(serverAddress);
    //config.setPort(5222);
    config.setPort(5222);
    config.setDebuggerEnabled(true);

    SSLContext sslContext = null;
    try {
        sslContext = createSSLContext(context);
        //sslContext.getSupportedSSLParameters();

    } catch (KeyStoreException e) {
        e.printStackTrace();
    } catch (KeyManagementException e){
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (CertificateException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();

    //} catch(NoSuchProviderException e){
    //    e.printStackTrace();
    }

    //config.setSocketFactory(new DummySSLSocketFactory());
    //config.setSocketFactory(SSLSocketFactory.getDefault());
    config.setCustomSSLContext(sslContext);
    //SSLSocketFactory socketFactory = sslContext.getSocketFactory();
    //NoSSLv3SocketFactory socketFactory = new NoSSLv3SocketFactory(sslContext.getSocketFactory());
    TLSSocketFactory socketFactory = new TLSSocketFactory(sslContext);
    //SSLSocketFactory noSSLv3Factory = new TlsOnlySocketFactory(sslContext.getSocketFactory());

    config.setSocketFactory(socketFactory);
    config.setEnabledSSLProtocols(new String[]{"TLSv1", "TLSv1.1", "TLSv1.2"});


    XMPPTCPConnection.setUseStreamManagementResumptiodDefault(true);
    XMPPTCPConnection.setUseStreamManagementDefault(true);
    connection = new XMPPTCPConnection(config.build());

    XMPPConnectionListener connectionListener = new XMPPConnectionListener();
    connection.addConnectionListener(connectionListener);
}

private SSLContext createSSLContext(Context context) throws KeyStoreException,
        NoSuchAlgorithmException, KeyManagementException, IOException, CertificateException {

    KeyStore trustStore;
    InputStream in = null;
    trustStore = KeyStore.getInstance("BKS");

    in = context.getResources().openRawResource(R.raw.keystore1);

    trustStore.load(in, "MY_STORE_PASSWORD".toCharArray());

    TrustManagerFactory trustManagerFactory = TrustManagerFactory
            .getInstance(KeyManagerFactory.getDefaultAlgorithm());
    trustManagerFactory.init(trustStore);
    //SSLContext sslContext = SSLContext.getInstance("TLS");
    SSLContext sslContext = null;
    try {
        //sslContext = SSLContext.getInstance("TLSv1", "AndroidOpenSSL");
        sslContext = SSLContext.getInstance("TLS");
    }
    catch(Exception e){
        e.printStackTrace();
    }

    sslContext.init(null, trustManagerFactory.getTrustManagers(), new SecureRandom());


    Log.d("SSL Protocol: ", sslContext.getProtocol());
    Log.d("SSL Provider: ", sslContext.getProvider().toString());
    String[] protocols = sslContext.getDefaultSSLParameters().getProtocols();
    sslContext.getDefaultSSLParameters().setProtocols(protocols);

    return sslContext;
}

TLSFactory代码为：

public class TLSSocketFactory extends SSLSocketFactory {

    private SSLSocketFactory internalSSLSocketFactory;

    public TLSSocketFactory() throws KeyManagementException, NoSuchAlgorithmException {
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, null, null);
        internalSSLSocketFactory = context.getSocketFactory();
    }

    public TLSSocketFactory(SSLContext sslContext){
        internalSSLSocketFactory = sslContext.getSocketFactory();
    }

    @Override
    public String[] getDefaultCipherSuites() {
        return internalSSLSocketFactory.getDefaultCipherSuites();
    }

    @Override
    public String[] getSupportedCipherSuites() {
        return internalSSLSocketFactory.getSupportedCipherSuites();
    }

    @Override
    public Socket createSocket() throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket());
    }

    @Override
    public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
    }

    @Override
    public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
    }

    @Override
    public Socket createSocket(InetAddress host, int port) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
    }

    private Socket enableTLSOnSocket(Socket socket) {
        if(socket != null && (socket instanceof SSLSocket)) {
            //((SSLSocket)socket).setEnabledProtocols(new String[] {"SSLv3","TLSv1", "TLSv1.1", "TLSv1.2"});
            ((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1", "TLSv1.1", "TLSv1.2"});
            Log.d("TLSSocketFactory: ", "setting TLS list");
        }
        if(socket!= null) {
            Log.d("TLSSocketFactory: ", "socket class: " +socket.getClass());
        }
        Log.d("TLSSocketFactory: ","Returning TLS Enabled Socket");

        return socket;
    }
}

我已经尝试了所有可以找到的解决方案，但仍然无法连接到xmpp服务器。 我也尝试过在wtfismyip.com上使用jabber服务器，结果相似。 现在停留在此超过2周。 希望能帮助您克服这一障碍。

Answer 1

回答的时间还不算晚，但是仍然..我想问题是因为您使用5222作为端口。 如果检查服务器设置，则可能会在服务器中找到5223作为客户端SSL端口设置。 如果是这样，只需进行更改即可解决此问题。
