java后台发起get请求获取响应数据

本文实例为大家分享了java后台发起get请求获取响应数据，供大家参考，具体内容如下

学习记录：

话不多说直接上代码：

package com.jl.chrometest;

import java.io.bufferedreader;
import java.io.inputstreamreader;
import java.net.httpurlconnection;
import java.net.url;
import java.net.urlconnection;
import java.nio.charset.standardcharsets;

/**
 * get请求测试
 * @author liujilong
 * @since 2019-7-18 10:26:49
 */
public class test {

 @org.junit.test
  public void test() throws exception{
  string result = get("http://www.baidu.com");
  system.out.println("result====="+result);
 }

 /**
  * get请求
  * @param url
  * @return
  * @throws exception
  */
 public string get(string url) throws exception {
  string content = null;
  urlconnection urlconnection = new url(url).openconnection();
  httpurlconnection connection = (httpurlconnection) urlconnection;
  connection.setrequestmethod("get");
  //连接
  connection.connect();
  //得到响应码
  int responsecode = connection.getresponsecode();
  if (responsecode == httpurlconnection.http_ok) {
   bufferedreader bufferedreader = new bufferedreader(new inputstreamreader
     (connection.getinputstream(), standardcharsets.utf_8));
   stringbuilder bs = new stringbuilder();
   string l;
   while ((l = bufferedreader.readline()) != null) {
    bs.append(l).append("\n");
   }
   content = bs.tostring();
  }
  return content;
 }
}

结果如图:
