java后台发起get请求获取响应数据学习记录: 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

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(http://www.amjmh.com/v/);
//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;
}
}
