HttpURLConnection绕过HTTPS的SSL验证

（这个jdk环境需要是1.8,以上）。

直接在类里面加一个static代码块

static {
        try {
            trustAllHttpsCertificates();
            HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
                public boolean verify(String urlHostName, SSLSession session) {
                    return true;
                }
            });
        } catch (Exception e) {
        }
    }

　　在调用如下方法：

private static void trustAllHttpsCertificates() throws NoSuchAlgorithmException, KeyManagementException {
        TrustManager[] trustAllCerts = new TrustManager[1];
        trustAllCerts[0] = new TrustAllManager();
        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, null);
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    }

    private static class TrustAllManager implements X509TrustManager {
        public X509Certificate[] getAcceptedIssuers() {
            return null;
        }

        public void checkServerTrusted(X509Certificate[] certs, String authType) throws CertificateException {
        }

        public void checkClientTrusted(X509Certificate[] certs, String authType) throws CertificateException {
        }
    }

这样就应该没有问题了。
