在Java的编程世界里面,我们有的时候,会经常访问一些HTTPS的网站,那么访问这些HTTPS的网站的时候,如果当前这个网站是自己企业内部的已知 的网站,或者我们信任的网站,这个时候,我们为了编写程序的方便,就不需要把当前网站的服务器的根证书以及中间证书导入到JKS里面,让在程序在调用HTTP协议的时候对服务器的服务器名和证书名进行对比。说了这么多,那么应该如何做呢?其实也挺简单的,请看下面的Java代码。
# 在类的开头加入一段static的代码
static { try { trustAllHttpsCertificates(); HttpsURLConnection.setDefaultHostnameVerifier ( new HostnameVerifier() { @Override public boolean verify(String urlHostName, SSLSession session) { // TODO Auto-generated method stub return true; } } ); } catch (Exception e) {} }
# trustAllHttpsCertificates()方法的实现
private static void trustAllHttpsCertificates() throws NoSuchAlgorithmException, KeyManagementException{ TrustManager[] trustAllCerts = new TrustManager[1]; trustAllCerts[0] = (TrustManager) 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 { } } }
简单吧!!!!!
