Android 4 +https（如何启动TLS1 1 and TLS1 2）-白红宇

之前用的网络请求框架是鸿洋的OkHttpUtils，网络请求在5.0手机上使用https没有问题，但是最近突然使用了一个4.4的系统，就报错SSLException ....咋地咋地

然后我们的副总给我们找一个博客，如何解决4.+系统出现的这个问题（虽然我现在还很有点懵逼...），然后添加上去后，就可以使用了。在Okgo ，OkHttpUtils 都可以用，那么的网络请求应该也可以用？！！（别的没有测） -然后我先贴一下那个仁兄的博客吧，使用TLSSocketFactory 类

然后就是在全局初始化的时候使用这个类，那个第二次参数，就用他提供的。 ··· OkHttpClient okHttpClient = null; try { HttpsUtils.SSLParams sslParams = HttpsUtils.getSslSocketFactory(null, null, null); okHttpClient = new OkHttpClient.Builder() .addInterceptor(new LoggerInterceptor("history")) .sslSocketFactory(new TLSSocketFactory() , sslParams.trustManager)//这里使用！！！ .build(); } catch (KeyManagementException e) { e.printStackTrace(); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } OkHttpUtils.initClient(okHttpClient); ···

用OKgo也一样的，第二个参数如果不想用框架自带的我在下面贴出来。

这是 TSsX509TrustManager ···

public class SsX509TrustManager implements X509TrustManager { private static TrustManager[] trustManagers; private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[]{};

@Overridepublic void checkClientTrusted(java.security.cert.X509Certificate[] x509Certificates, String s) throws java.security.cert.CertificateException {    //To change body of implemented methods use File | Settings | File Templates.}@Overridepublic void checkServerTrusted(java.security.cert.X509Certificate[] x509Certificates, String s) throws java.security.cert.CertificateException {    //To change body of implemented methods use File | Settings | File Templates.}@Overridepublic java.security.cert.X509Certificate[] getAcceptedIssuers() {    return new java.security.cert.X509Certificate[0];}public boolean isClientTrusted(X509Certificate[] chain) {    return true;}public boolean isServerTrusted(X509Certificate[] chain) {    return true;}public static X509Certificate[] get_AcceptedIssuers() {    return _AcceptedIssuers;}/** * 允许所有的SSL请求，添加在new StringRequest()之前 */public static void allowAllSSL() {    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {        @Override        public boolean verify(String arg0, SSLSession arg1) {            // TODO Auto-generated method stub            return true;        }    });    SSLContext context = null;    if (trustManagers == null) {        trustManagers = new TrustManager[]{new SsX509TrustManager()};    }    try {        context = SSLContext.getInstance("TLS");        context.init(null, trustManagers, new SecureRandom());    } catch (NoSuchAlgorithmException e) {        e.printStackTrace();    } catch (KeyManagementException e) {        e.printStackTrace();    }    HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());}复制代码

}
