JAVA如何调用对方http接口得到返回数据

​​https://tcc.taobao.com/cc/json/mobile_tel_segment.htm?tel="手机号码"​​

jsp代码：

<form action="https://tcc.taobao.com/cc/json/mobile_tel_segment.htm" method="post">
请输入手机号:<input type="text" name="tel" value="">
<input type="submit" value="查询 ">
</form>

访问jsp页面，输入测试手机号码：13535382112，点击查询按钮，得到以下返回结果

__GetZoneResult_ = {
mts:'1353538',
province:'广东',
catName:'中国移动',
telString:'13535382112',
areaVid:'30517',
ispVid:'3236139',
carrier:'广东移动'
}

通过JAVA代码访问：

package com.interfaces.demo1;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class InterfaceTest {
public static void main(String[] args) throws Exception {
// 方法一
System.out.println(InterfaceTest.getURLContent());
// 方法二
String urlStr = "https://tcc.taobao.com/cc/json/mobile_tel_segment.htm?tel=13535382112";
System.out.println(InterfaceTest.getURLContent(urlStr));
}

public static String getURLContent() throws Exception {
String strURL = "https://tcc.taobao.com/cc/json/mobile_tel_segment.htm?tel=13535382112";
URL url = new URL(strURL);
HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
httpConn.setRequestMethod("GET");
httpConn.connect();

BufferedReader reader = new BufferedReader(new InputStreamReader(httpConn.getInputStream()));
String line;
StringBuffer buffer = new StringBuffer();
while ((line = reader.readLine()) != null) {
buffer.append(line);
}
reader.close();
httpConn.disconnect();
System.out.println(buffer.toString());
System.out.println(buffer);
System.out.println(buffer.toString());
return buffer.toString();
}

/**
* 程序中访问http数据接口
*/
public static String getURLContent(String urlStr) {
/** 网络的url地址 */
URL url = null;
/** http连接 */
HttpURLConnection httpConn = null;
/**//** 输入流 */
BufferedReader in = null;
StringBuffer sb = new StringBuffer();
try {
url = new URL(urlStr);
in = new BufferedReader(new InputStreamReader(url.openStream(), "GBk"));
String str = null;
while ((str = in.readLine()) != null) {
sb.append(str);
}
} catch (Exception ex) {

} finally {
try {
if (in != null) {
in.close();
}
} catch (IOException ex) {
}
}
String result = sb.toString();
return result;
}
}
