java调用新浪接口根据Ip查询所属地区

        String[] areaArr = new String[10]; 
        String[] newAreaArr = new String[3];
        urlString = "http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip="+ip;
        try {

            }
            br.close();
            is.close();
            conn.disconnect();

        return newAreaArr;
    }

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。
