我有一个奇怪的问题，在这个问题上，改造一直把我抛在脑后

SSL握手中止: ssl=0x618d9c18:系统调用时I/O错误，由对等方重置连接

在kitkat中，相同的代码在棒棒糖设备中工作得很好。我正在使用OkHttpClient客户端，如下所示

public OkHttpClient getUnsafeOkHttpClient() {
    try {
        final TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
            @Override
            public void checkClientTrusted(
                    java.security.cert.X509Certificate[] chain,
                    String authType) {
            }
            @Override
            public void checkServerTrusted(
                    java.security.cert.X509Certificate[] chain,
                    String authType) {
            }
            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return new java.security.cert.X509Certificate[0];
            }
        } };

        int cacheSize = 10 * 1024 * 1024; // 10 MB
        Cache cache = new Cache(getCacheDir(), cacheSize);
        final SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, trustAllCerts,
                new java.security.SecureRandom());
        final SSLSocketFactory sslSocketFactory = sslContext
                .getSocketFactory();
        OkHttpClient okHttpClient = new OkHttpClient();
        okHttpClient = okHttpClient.newBuilder()
                .cache(cache)
                .sslSocketFactory(sslSocketFactory)
                .hostnameVerifier(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER).build();
        return okHttpClient;
    } catch (Exception e) {
        throw new RuntimeException(e);
    }

}

我正在利用这个客户进行这样的改造

Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(URL)
            .client(getUnsafeOkHttpClient())
            .addConverterFactory(GsonConverterFactory.create())
            .build();

编辑:在这里添加getUnsafeOkHttpClient()没有任何效果，因此不建议使用getUnsafeOkHttpClient()绕过ssl检查。

FYI :问题是因为api端点只支持TLS 1.2，默认情况下在16<device<20设备上禁用它。因此，对于16<device<20，，创建一个自定义SSLSocketFactory

tls1.2

sslhandshakeexception

android

retrofit2

最后找到了这个问题的解决方案，这不是一个完整的解决方案，因为它是https://stackoverflow.com/users/40013/jesse-wilson从okhttp，square 这里提到的一个黑客。正如我提到的，这是一个简单的黑客，我不得不将我的SSLSocketFactory变量重命名为

private SSLSocketFactory delegate;

请注意，如果您指定了委托以外的任何名称，则会引发错误。我在下面发布我的完整解决方案

这是我的TLSSocketFactory课

public class TLSSocketFactory extends SSLSocketFactory {

private SSLSocketFactory delegate;
private TrustManager[] trustManagers;

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

private void generateTrustManagers() throws KeyStoreException, NoSuchAlgorithmException {
    TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
    trustManagerFactory.init((KeyStore) null);
    TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();

    if (trustManagers.length != 1 || !(trustManagers[0] instanceof X509TrustManager)) {
        throw new IllegalStateException("Unexpected default trust managers:"
                + Arrays.toString(trustManagers));
    }

    this.trustManagers = trustManagers;
}


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

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

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

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

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

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

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

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

private Socket enableTLSOnSocket(Socket socket) {
    if(socket != null && (socket instanceof SSLSocket)) {
        ((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1.1", "TLSv1.2"});
    }
    return socket;
}

@Nullable
public X509TrustManager getTrustManager() {
    return  (X509TrustManager) trustManagers[0];
}

}

这就是我如何使用它与okhttp和改造

 OkHttpClient client=new OkHttpClient();
    try {
        TLSSocketFactory tlsSocketFactory=new TLSSocketFactory();
        if (tlsSocketFactory.getTrustManager()!=null) {
            client = new OkHttpClient.Builder()
                    .sslSocketFactory(tlsSocketFactory, tlsSocketFactory.getTrustManager())
                    .build();
        }
    } catch (KeyManagementException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    } catch (KeyStoreException e) {
        e.printStackTrace();
    }

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(URL)
            .client(client)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

编辑：现在不推荐使用public Builder sslSocketFactory(SSLSocketFactory sslSocketFactory)方法，我们应该使用public Builder sslSocketFactory( SSLSocketFactory sslSocketFactory, X509TrustManager trustManager)，因为我在答案中已经更新了。这是因为X509TrustManager是OkHttp需要构建一个干净的证书链的字段，这个字段在不推荐的方法中没有被暂停。

我修改了@Navneet Krishna答案，因为OkHttpClient.Builder方法。builder.sslSocketFactory(tlsSocketFactory)现在被否决了。

public class TLSSocketFactory extends SSLSocketFactory {

private final SSLSocketFactory delegate;
private TrustManager[] trustManagers;

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

private void generateTrustManagers() throws KeyStoreException, NoSuchAlgorithmException {
    TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
    trustManagerFactory.init((KeyStore) null);
    TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();

    if (trustManagers.length != 1 || !(trustManagers[0] instanceof X509TrustManager)) {
        throw new IllegalStateException("Unexpected default trust managers:"
                + Arrays.toString(trustManagers));
    }

    this.trustManagers = trustManagers;
}

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

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

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

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

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

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

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

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

private Socket enableTLSOnSocket(Socket socket) {
    if (socket instanceof SSLSocket) {
        ((SSLSocket) socket).setEnabledProtocols(new String[]{"TLSv1.1", "TLSv1.2"});
    }
    return socket;
}

@Nullable
public X509TrustManager getTrustManager() {
    return  (X509TrustManager) trustManagers[0];
}
}

你需要这样分配它：

TLSSocketFactory tlsTocketFactory = new TLSSocketFactory();
client = new OkHttpClient.Builder()
            .sslSocketFactory(tlsSocketFactory, tlsSocketFactory.getTrustManager());
            .build();

除了Navneet之外，我还必须在我的App类中做下一个：

ProviderInstaller.installIfNeededAsync

根据https://developer.android.com/training/articles/security-gms-provider的说法，这是因为我需要更新安全提供者以防止SSL攻击。

我的应用程序类：

public class AppClass extends MultiDexApplication {

private static final String TAG = AppClass.class.getName();

private static Context context;
private static AuthAPI authAPI;
private static RestAPI buyersAPI;

@Override
public void onCreate() {
    super.onCreate();
    /* enable SSL compatibility in pre-lollipop devices */
    upgradeSecurityProvider();

    createAuthAPI();
    createRestAPI();
}

private void upgradeSecurityProvider() {
    try{
        ProviderInstaller.installIfNeededAsync(this, new ProviderInstaller.ProviderInstallListener() {
            @Override
            public void onProviderInstalled() {
                Log.e(TAG, "New security provider installed.");
            }

            @Override
            public void onProviderInstallFailed(int errorCode, Intent recoveryIntent) {
                GooglePlayServicesUtil.showErrorNotification(errorCode, BuyersApp.this);
                Log.e(TAG, "New security provider install failed.");
            }
        });
    }catch (Exception ex){
        Log.e(TAG, "Unknown issue trying to install a new security provider", ex);
    }

}

private void createAuthAPI() {
    OkHttpClient.Builder authAPIHttpClientBuilder = new OkHttpClient.Builder();

    Retrofit retrofit = new Retrofit.Builder()
            .client(enableTls12OnPreLollipop(authAPIHttpClientBuilder).build())
            .baseUrl(DomainLoader.getInstance(context).getAuthDomain())
            .addConverterFactory(GsonConverterFactory.create())
            .build();
    authAPI = retrofit.create(AuthAPI.class);
}

private static OkHttpClient.Builder enableTls12OnPreLollipop(OkHttpClient.Builder client) {
    if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 22) {
        try {
            SSLContext sc = SSLContext.getInstance("TLSv1.2");
            sc.init(null, null, null);

            TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(
                    TrustManagerFactory.getDefaultAlgorithm());
            trustManagerFactory.init((KeyStore) null);
            TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
            if (trustManagers.length != 1 || !(trustManagers[0] instanceof X509TrustManager)) {
                throw new IllegalStateException("Unexpected default trust managers:"
                        + Arrays.toString(trustManagers));
            }
            X509TrustManager trustManager = (X509TrustManager) trustManagers[0];

            client.sslSocketFactory(new Tls12SocketFactory(sc.getSocketFactory()), trustManager);

            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;
}

private void createRestAPI() {
    OkHttpClient.Builder restAPIHttpClientBuilder = new OkHttpClient.Builder();
    buyersAPIHttpClientBuilder.readTimeout(60, TimeUnit.SECONDS);
    buyersAPIHttpClientBuilder.connectTimeout(60, TimeUnit.SECONDS);
    buyersAPIHttpClientBuilder.writeTimeout(600, TimeUnit.SECONDS);
    buyersAPIHttpClientBuilder.addInterceptor(new NetworkErrorInterceptor());
    buyersAPIHttpClientBuilder.addInterceptor(new TokenVerificationInterceptor());

    Retrofit retrofit = new Retrofit.Builder()
            .client(enableTls12OnPreLollipop(restAPIHttpClientBuilder).build())
            .baseUrl(DomainLoader.getInstance(context).getDomain())
            .addConverterFactory(GsonConverterFactory.create(new GsonBuilder().setLenient().create()))
            .addConverterFactory(ScalarsConverterFactory.create())
            .build();

    buyersAPI = retrofit.create(RestAPI.class);
}
}

我的Tls12SocketFactory课程：

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;
}
}

在所有KitKat及以上设备中，它的工作就像一种魅力。
