这是我的第一篇文章，我会尽力做到尽可能清楚(对不起我的英语)。

这是我的麻烦，我正在使用 retrofit:1.9.0 和 okhttp:2.7.5 来执行 API 调用。一切都很好，直到我的服务器提供商禁用 SLLv2 和 SSLv3 导致安全问题(3 月 1 日发现 Drown 失败)。

现在我检查有关我的提供商的信息，他只允许来自 https://www.ssllabs.com/ 的 TLSv1 with cypher (TLS 1.0 TLS_RSA_WITH_3DES_EDE_CBC_SHA No FS) .

好的，这是我完成的所有测试和结果:

[更新问题已解决]

在我的第二个答案中找到解决这个问题的方法。

更新 看来问题出在 google API 版本上。当我在 API 18 上测试时，一切正常。当它在 Android 大于或等于 5.0.0 时失败。

第一次测试

session 。回顾:

• compileSdkVersion 23
• buildToolsVersion '23.0.2'
• minSdkVersion 18
• targetSdkVersion 21
• 改造:1.9.0
• okhttp:2.7.5
• Android 版本 > 5.0.0(但在每台设备上都一样...)

休息客户端(LoginRestClient):

public class LoginRestClient
{
    private static final String BASE_URL = "";
    private LoginApiService apiService;

    public LoginRestClient()
    {
        Gson gson = new GsonBuilder()
                .setDateFormat("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'SSS'Z'")
                .create();

        RestAdapter restAdapter = new RestAdapter.Builder()
                .setLogLevel(RestAdapter.LogLevel.FULL)
                .setEndpoint(ApiIntentService.getHostAddress())
                .setConverter(new GsonConverter(gson))
                .setClient(new OkClient(ApiIntentService.getConnectionHttpClient()))
                .build();

        apiService = restAdapter.create(LoginApiService.class);
    }

    public LoginApiService getApiService() {
        return apiService;
    }
}

创建客户端OkHttpClient getConnectionHttpClient()函数

public static OkHttpClient getConnectionHttpClient()
{
    OkHttpClient okHttpClient = new OkHttpClient();
    okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
    okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);



        ConnectionSpec specs = new ConnectionSpec.Builder(ConnectionSpec.COMPATIBLE_TLS)
                .tlsVersions(TlsVersion.TLS_1_0)
                .cipherSuites(CipherSuite.TLS_RSA_WITH_3DES_EDE_CBC_SHA)
                .build();

        okHttpClient.setConnectionSpecs(Collections.singletonList(specs));

    return okHttpClient;
}

自定义回调导致公共(public)无效失败(RetrofitError 错误)

java.net.UnknownServiceException:无法找到可接受的协议(protocol)。 isFallback=false，模式=[ConnectionSpec(cipherSuites=[TLS_RSA_WITH_3DES_EDE_CBC_SHA]，tlsVersions=[TLS_1_0]，supportsTlsExtensions=true)]，支持的协议(protocol)=[SSLv3、TLSv1、TLSv1.1、TLSv1.2]

第二次测试

我制作了一个自定义 SSLSocketFactory 来禁用 SSLv3 并强制使用 TLS:

/**
 * @author fkrauthan
 */
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();
    }

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

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

    @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[] {"TLSv1"});
        }
        return socket;
    }
}

我是这样使用的:

public static OkHttpClient getConnectionHttpClient()
    {
        OkHttpClient okHttpClient = new OkHttpClient();
        okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
        okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);

        try {
            TLSSocketFactory tlsSocketFactory = new TLSSocketFactory();
            HttpsURLConnection.setDefaultSSLSocketFactory(tlsSocketFactory);
            okHttpClient.setSslSocketFactory(tlsSocketFactory);
        } catch (KeyManagementException e) {
            e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }

 return okHttpClient;
}

自定义回调导致公共(public)无效失败(RetrofitError 错误)

javax.net.ssl.SSLProtocolException:SSL 握手中止:ssl=0x7f87885280:SSL 库失败，通常是协议(protocol)错误 错误:14077410:SSL 例程:SSL23_GET_SERVER_HELLO:sslv3 警报握手失败(外部/openssl/ssl/s23_clnt.c:770 0x7f87c2fdf0:0x00000000)

如果有人能帮助我，那就太好了。我所有的应用程序都关闭了，从昨天早上开始我就在与这个问题作斗争以恢复我的服务。我正在一根一根地脱头发...

提前致谢。

大家好，折腾了三天三夜，终于解决了。 所以感谢这里的解决方案:

How to disable SSLv3 in android for HttpsUrlConnection?

和这个图书馆:https://guardianproject.info/code/netcipher

它允许在禁用 SSLv2 和 SSlv3 的情况下为 Android 提供更好的密码和 TLS 工作方式。

        public boolean equals(Object o) {
            return delegate.equals(o);
        }
    }
}

现在(在我的改造案例中)像这样使用它:

所以首先，添加一个静态方法(或者您希望在使用时创建它)以使用我们之前创建的 NoSSLv3Factory.java 类创建一个 okHttpClient。

public static OkClient createClient(int readTimeout, TimeUnit readTimeoutUnit, int connectTimeout, TimeUnit connectTimeoutUnit)
{
    final OkHttpClient okHttpClient = new OkHttpClient();
    okHttpClient.setReadTimeout(readTimeout, readTimeoutUnit);
    okHttpClient.setConnectTimeout(connectTimeout, connectTimeoutUnit);

    try {
        URL url = new URL(ApiIntentService.getHostAddress());
        SSLSocketFactory NoSSLv3Factory = new NoSSLv3SocketFactory(url);
        okHttpClient.setSslSocketFactory(NoSSLv3Factory);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return new OkClient(okHttpClient);

}

然后，在我的例子中，当你创建你的 RestAdapter 时就这样，并且不要忘记设置你的客户端。

public class LoginRestClient
{
    private static final String BASE_URL = "";
    private LoginApiService apiService;

    public LoginRestClient()
    {
        Gson gson = new GsonBuilder()
                .setDateFormat("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'SSS'Z'")
                .create();

        RestAdapter restAdapter = new RestAdapter.Builder()
                .setLogLevel(RestAdapter.LogLevel.FULL)
                .setEndpoint(ApiIntentService.getHostAddress())
                .setConverter(new GsonConverter(gson))
                .setClient(ApiIntentService.createClient(60, TimeUnit.SECONDS, 20, TimeUnit.SECONDS))
                .build();

        apiService = restAdapter.create(LoginApiService.class);
    }

    public LoginApiService getApiService() {
        return apiService;
    }
}

有了这个，它应该可以工作了。 我希望它对其他人有用。
