Android (23) - Smack (4.1.8) - XMPP - "SSL23_GET_SERVER_HELLO:unknown protocol"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。我直接在手机(Galaxy S6 和 Galaxy E7)上进行测试。我正在尝试连接到 xmpp.jp。尝试连接时出现此异常:

使用这个 tutorial .我试过 DummySSLSocketFactory 、[NoSSLFactory] ​​和 [TLSFactory] ​​解决方案(无法发布超过 2 个链接 :|)。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 代码是:

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;
    }
}

我已经尝试了我能找到的所有解决方案，但仍然无法连接到 xmpp 服务器。我还在 wtfismyip.com 上尝试了 jabber 服务器，结果相似。现在在这一点上停留了 2 个多星期。非常感谢帮助克服这个障碍。

Answer 1

回答的时间太晚了，但还是..我想问题是因为你使用 5222 作为端口。如果您检查服务器设置，您可能会发现 5223 作为服务器中设置的客户端 SSL 端口。如果是这样，只需更改它即可解决此问题。
