1.Httpclient jar 版本:httpclient-4.5.3.jar

2.GET请求抛出异常:

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException

3.GET 方法解决异常, 修改GET方法如下:

public String doHttpClientGetRequestForSSL(String request) throws ClientProtocolException, IOException {
       CloseableHttpClient httpclient;
       BufferedReader in = null;
       String responseAsString = null;
       try {
           httpclient = HttpClients.custom().setSSLSocketFactory(new SSLConnectionSocketFactory(SSLContexts.custom().loadTrustMaterial(null, new TrustSelfSignedStrategy()).build())).build();
           HttpUriRequest httpGet = new HttpGet(request);
           CloseableHttpResponse response = httpclient.execute(httpGet);
//           System.out.println(response.getStatusLine());
           responseAsString = EntityUtils.toString(response.getEntity());
//           System.out.println(responseAsString);
           response.close();
       } catch (KeyManagementException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       } catch (NoSuchAlgorithmException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       } catch (KeyStoreException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
       return responseAsString;
   }
