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:
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
