java - Android 4.4.2 SSL 握手中止

Question

代码适用于我的 Genymotion Android 4.4.4 模拟器，但不适用于我正在使用的设备 (4.4.2)。

我尝试了很多“信任所有证书”的解决方法，但都无济于事(我认为这不是问题，因为证书是 AOK)。

我想我已经识别了密码(使用我桌面上的 wireshark 跟踪)； TLS 0x00 0x1E 这似乎有点少见？

知道如何解决吗？

这是我的代码

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
CloseableHttpClient client = HttpClientBuilder.create().setSSLSocketFactory(sslsf).build();
String baseURL = "https://mysite.co.uk/api/";
HttpGetHC4 request = new HttpGetHC4(baseURL + "/authenticate?user=abcd&password=1234");
CloseableHttpResponse response = client.execute(request);

还有错误；

尝试使用不同的技术/库；

        RequestQueue queue = Volley.newRequestQueue(this);
        String url ="https://mysite.co.uk/api/authenticate?user=abcd&password=1234";

        // Request a string response from the provided URL.
        StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        // Display the first 500 characters of the response string.
                        Log.d("response: ", response);
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Log.d("response: ", error.toString());
            }
        });
        // Add the request to the RequestQueue.
        queue.add(stringRequest);

或者使用来自 Javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: Failure in SSL library, usually a protocol error 的 NoSSLv3SocketFactory hack ;

        HttpStack stack = new HurlStack(null, new NoSSLv3SocketFactory());
        RequestQueue queue = Volley.newRequestQueue(this, stack);

Answer 1

Android 使用不同的协议(protocol)进行网络操作。

不同安卓版本的默认配置。

我找到了 OkHttpClient 的解决方案。

Protocol    Supported (API Levels)  Enabled by default (API Levels)

SSLv3       1–25                    1–22
TLSv1       1+                      1+
TLSv1.1     16+                     20+
TLSv1.2     16+                     20+

所以我们必须在 Android VERSION >= 16 & VERSION < 22 中更改连接协议(protocol)。

创建java文件Tls12SocketFactory.java

/**
 * Enables TLS v1.2 when creating SSLSockets.
 * <p/>
 * For some reason, android supports TLS v1.2 from API 16, but enables it by
 * default only from API 20.
 * @link https://developer.android.com/reference/javax/net/ssl/SSLSocket.html
 * @see SSLSocketFactory
 */
public class Tls12SocketFactory extends SSLSocketFactory {
    private static final String[] TLS_V12_ONLY = {"TLSv1.2"};

    final SSLSocketFactory delegate;

    public Tls12SocketFactory(SSLSocketFactory base) {
        this.delegate = base;
    }

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

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

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

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

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

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

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

    private Socket patch(Socket s) {
        if (s instanceof SSLSocket) {
            ((SSLSocket) s).setEnabledProtocols(TLS_V12_ONLY);
        }
        return s;
    }
}

将此方法放在代码中的某个位置。

public static OkHttpClient.Builder enableTls12OnPreLollipop(OkHttpClient.Builder client) {
        if (Build.VERSION.SDK_INT >= 16 && Build.VERSION.SDK_INT < 22) {
            try {
                SSLContext sc = SSLContext.getInstance("TLSv1.2");
                sc.init(null, null, null);
                client.sslSocketFactory(new Tls12SocketFactory(sc.getSocketFactory()));

                ConnectionSpec cs = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
                        .tlsVersions(TlsVersion.TLS_1_2).build();

                List<ConnectionSpec> specs = new ArrayList<>();
                specs.add(cs);
                specs.add(ConnectionSpec.COMPATIBLE_TLS);
                specs.add(ConnectionSpec.CLEARTEXT);

                client.connectionSpecs(specs);
            } catch (Exception exc) {
                Log.e("OkHttpTLSCompat", "Error while setting TLS 1.2", exc);
            }
        }

        return client;
    }

    public OkHttpClient getNewHttpClient() {
        OkHttpClient.Builder client = new OkHttpClient.Builder().followRedirects(true).followSslRedirects(true)
                .retryOnConnectionFailure(true).cache(null).connectTimeout(5, TimeUnit.SECONDS)
                .writeTimeout(5, TimeUnit.SECONDS).readTimeout(5, TimeUnit.SECONDS);

        return enableTls12OnPreLollipop(client).build();
    }

如下创建 OkHttp 实例:

private OkHttpClient getNewHttpClient() {
    OkHttpClient.Builder client = new OkHttpClient.Builder()
            .followRedirects(true)
            .followSslRedirects(true)
            .retryOnConnectionFailure(true)
            .cache(null)
            .connectTimeout(5, TimeUnit.SECONDS)
            .writeTimeout(5, TimeUnit.SECONDS)
            .readTimeout(5, TimeUnit.SECONDS);

    return enableTls12OnPreLollipop(client).build();
}

像这样使用客户端对象:

OkHttpClient client = getNewHttpClient();
Request.Builder requestBuilder = new Request.Builder();
URL url = new URL("YOUR_URL_LINK");
Request request = requestBuilder.url(url).build();
Call call = client.newCall(request);
Response response = call.execute();
