JAVA连接HTTPS

使用Apache的HttpClient 和 HttpCore

https://hc.apache.org

package cn.getssl.https;

import java.io.BufferedReader;
import java.io.InputStreamReader;

import javax.net.ssl.SSLContext;

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContexts;
import org.apache.http.util.EntityUtils;



public class ConnectionHttps {


	public static void main(String[] args) throws Exception {
		// TODO Auto-generated method stub
		SSLContext sslcontext = SSLContexts.createSystemDefault();
        // Allow TLSv1 protocol only
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                sslcontext,
                new String[] { "TLSv1" },
                null,
                SSLConnectionSocketFactory.getDefaultHostnameVerifier());
        CloseableHttpClient httpclient = HttpClients.custom()
                .setSSLSocketFactory(sslsf)
                .build();
		try {

            HttpGet httpget = new HttpGet("https://www.baidu.com/");

            System.out.println("Executing request " + httpget.getRequestLine());

            CloseableHttpResponse response = httpclient.execute(httpget);
            try {
                HttpEntity entity = response.getEntity();
                BufferedReader in = new BufferedReader(new InputStreamReader(entity.getContent()));
                while(in.ready()){
                	System.out.println(in.readLine());
                }
                System.out.println("----------------------------------------");
                System.out.println(response.getStatusLine());
                
                
               
                EntityUtils.consume(entity);
            } finally {
                response.close();
            }
        } finally {
            httpclient.close();
        }
	}
