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。
js方法
<script src="http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js" type="text/javascript"></script>
<script type="text/javascript">
function getIpPlace() {
alert(remote_ip_info["province"] + "省" + , + remote_ip_info["city"] + "市")
}
</script>
