Java调用新浪api通过Ip查询地区

代码如下

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

import javax.servlet.http.HttpServletRequest;

public class sinaIpUtil {
  
  public static void main(String[] args) {
  
    String ip = "223.104.145.001";
    String[] areaArr = getAreaInfoList(ip);
    for (int i = 0; i < areaArr.length; i++) {
      System.out.println(areaArr[i]);
    }

  }
  
  public static String[] getAreaInfoList(String ip){
    String urlString = "";
    String[] areaArr = new String[10]; 
    String[] newAreaArr = new String[3];
    urlString = "http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip="+ip;
    try {
      URL url = new URL(urlString);
      HttpURLConnection conn = (HttpURLConnection) url.openConnection();
      conn.connect();
      InputStream is = conn.getInputStream();
      BufferedReader br = new BufferedReader(new InputStreamReader(is,"gb2312"));
      String line ="";
      StringBuffer resultBuffer = new StringBuffer();
      while ((line=br.readLine())!=null) {
 resultBuffer.append(line);
 
      }
      br.close();
      is.close();
      conn.disconnect();
      areaArr = (resultBuffer.toString()).split("  ");
      newAreaArr[0] = areaArr[3];
      newAreaArr[1] = areaArr[4];
      newAreaArr[2]=areaArr[5];
    } catch (Exception e) {
      // TODO: handle exception
    }
    
    return newAreaArr;
  }
  
  
  public static String getRemoteAddr(HttpServletRequest request, int flag) {
    String result = "";
    int port = 80;
    try {
      port = request.getServerPort();
      if (flag == 1) {
 if (port == 80)
   result = request.getHeader("X-Real-IP");
 else
   result = request.getRemoteAddr();
      } else {
 result = request.getRemoteAddr();
      }

    } catch (Exception e) {
      ;
    } finally {
      return result;
    }
  }

}

说说为什么我使用新浪的接口，起初是用的淘宝的接口，然后各种出错，因为我是想把库里以前的用户，根据Ip，新增对应的地区，需要大批量执行，结果用淘宝的接口，不是报超时，就是延缓，设置线程休眠，防止跨越淘宝规定的频率也不行，最后无奈只有舍去，结果用新浪的试下，什么都不用改，安静的稳定执行完毕，所以发出来供各位研究。
