关键代码：使用淘宝提供的接口，使用JsonPath解析JSON字符串
public String getProvideByPhoneNum( String phoneNum){
String province = null;
try {
String url = "http://tcc.taobao.com/cc/json/mobile_tel_segment.htm?tel="+phoneNum;
String s = HttpUtils.doGet(url.trim());
s = s.replace("__GetZoneResult_ = ","");
province = JsonPath.parse(s).read("$.province");
} catch (Exception e) {
e.printStackTrace();
}
return province;
}
http请求工具类，使用HttpClient工具类
public class HttpUtils {
private static final Logger LOG = LoggerFactory.getLogger(HttpUtils.class);
public static String Curl(String PostUrl, String[] Parameters) throws Exception {
if (null == PostUrl || null == Parameters || Parameters.length == 0) {
return null;
}
String result = "";
PrintWriter out = null;
BufferedReader in = null;
try {
//建立URL之间的连接
URLConnection conn = new URL(PostUrl).openConnection();
//设置通用的请求属性
conn.setRequestProperty("Host", "data.zz.baidu.com");
conn.setRequestProperty("User-Agent", "curl/7.12.1");
conn.setRequestProperty("Content-Length", "83");
conn.setRequestProperty("Content-Type", "text/plain");
//发送POST请求必须设置如下两行
conn.setDoInput(true);
conn.setDoOutput(true);
//获取conn对应的输出流
out = new PrintWriter(conn.getOutputStream());
//发送请求参数
String param = "";
for (String s : Parameters) {
param += s + "\n";
}
out.print(param.trim());
//进行输出流的缓冲
out.flush();
//通过BufferedReader输入流来读取Url的响应
in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
result += line;
}
} catch (Exception e) {
System.out.println("发送post请求出现异常！" + e);
e.printStackTrace();
} finally {

out.close();

if (in != null) {
in.close();
}
} catch (IOException ex) {
