httpclient4.3访问https

1、创建一个访问https的工具类

import com.alibaba.fastjson.JSONObject;

public class HttpClientUtil {
	private static Logger logger = Logger.getLogger(HttpClientUtil.class);
	private static final int TIME_OUT = 120000;

	public static CloseableHttpClient createSSLClientDefault(){
		try {
		             SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
		                 //信任所有
		                 public boolean isTrusted(X509Certificate[] chain,
		                                 String authType) throws CertificateException {
		                     return true;
		                 }
		             }).build();
		             SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);
		             return HttpClients.custom().setSSLSocketFactory(sslsf).build();
		         } catch (KeyManagementException e) {
		             e.printStackTrace();
		         } catch (NoSuchAlgorithmException e) {
		             e.printStackTrace();
		         } catch (KeyStoreException e) {
		             e.printStackTrace();
		         }
		         return  HttpClients.createDefault();
		}
 }

2测试

1 CloseableHttpClient httpClient = HttpClientUtil.createSSLClientDefault();
2 HttpGet get = new HttpGet();
3 get.setURI(new URI("你的https://地址"));
4 httpClient.execute(get）
