解决办法
上面的几种异常是请求不信任的https网站或配置有问题的https网站代码所抛出的异常。处理这几种异常,在代码添加一个静态的static代码块,做一下相关的配置,代码如下:
static { TrustManager[] trustAllCertificates = new TrustManager[] { new X509TrustManager() { @Override public X509Certificate[] getAcceptedIssuers() { return null; // Not relevant. } @Override public void checkClientTrusted(X509Certificate[] certs, String authType) { // Do nothing. Just allow them all. } @Override public void checkServerTrusted(X509Certificate[] certs, String authType) { // Do nothing. Just allow them all. } } }; HostnameVerifier trustAllHostnames = new HostnameVerifier() { @Override public boolean verify(String hostname, SSLSession session) { return true; // Just allow them all. } }; try { System.setProperty("jsse.enableSNIExtension", "false"); SSLContext sc = SSLContext.getInstance("SSL"); sc.init(null, trustAllCertificates, new SecureRandom()); HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory()); HttpsURLConnection.setDefaultHostnameVerifier(trustAllHostnames); } catch (GeneralSecurityException e) { throw new ExceptionInInitializerError(e); } }
