问题：在http请求https接口过程中经常会遇到SSL证书检查或者证书过期

** sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed **

解决办法：绕过证书检查

代码如下：

public static byte[] getFile(String url) throws  Exception {log.info("get file url:"+url);try {/*HttpClientBuilder builder = HttpClients.custom();builder.setSSLHostnameVerifier((hostName, sslSession) -> {return true; // 证书校验通过});*///CloseableHttpClient httpclient = builder.build();//CloseableHttpClient httpclient =  createSSLClientDefault();DefaultHttpClient httpclient = new DefaultHttpClient();enableSSL(httpclient);HttpGet request = new HttpGet(url);CloseableHttpResponse response = httpclient.execute(request);int statusCode = response.getStatusLine().getStatusCode();if (statusCode == HttpStatus.SC_OK) {HttpEntity entity = response.getEntity();if(entity == null) return null;byte[] imgByte = EntityUtils.toByteArray(entity);return imgByte;}}catch (Exception ex){log.error("get file error:"+ex.getMessage());ex.printStackTrace();throw ex;}return null;}/*** 访问https的网站* @param httpclient*/private static void enableSSL(DefaultHttpClient httpclient){//调用ssltry {SSLContext sslcontext = SSLContext.getInstance("TLS");sslcontext.init(null, new TrustManager[] { truseAllManager }, null);SSLSocketFactory sf = new SSLSocketFactory(sslcontext);sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);Scheme https = new Scheme("https", sf, 443);httpclient.getConnectionManager().getSchemeRegistry().register(https);} catch (Exception e) {e.printStackTrace();}}/*** 重写验证方法，取消检测ssl*/private static TrustManager truseAllManager = new X509TrustManager(){public void checkClientTrusted(java.security.cert.X509Certificate[] arg0, String arg1)throws CertificateException {// TODO Auto-generated method stub}public void checkServerTrusted(java.security.cert.X509Certificate[] arg0, String arg1)throws CertificateException {// TODO Auto-generated method stub}public java.security.cert.X509Certificate[] getAcceptedIssuers() {// TODO Auto-generated method stubreturn null;}};
};
