js根据IP地址获取当前的省市

3.阿里巴巴提供了接口，但不支持js跨域请求回调，我们可以在java代码中请求，返回参数：

//工具类
public class ResponseUtil {public static void write(HttpServletResponse response,Object o)throws Exception{response.setContentType("text/html;charset=utf-8");PrintWriter out=response.getWriter();out.println(o.toString());out.flush();out.close();}}

js:客户端调用java后台

<script type="text/javascript">$(function(){var ipServer = "localhost:8080/projectweb";$.ajax({url:ipServer+"/public/ipquery/getIpInfo?callback=?",async :false,dataType:"jsonp",type:'get',success:function(data){console.log(data)},error:function(XMLHttpRequest, textStatus, errorThrown) {console.log(XMLHttpRequest.status);console.log(XMLHttpRequest.readyState);console.log(textStatus);}});}
</script>

data 的内容：

{"nation":"中国","city":"兰州","cityCode":"620100","provice":"甘肃","isp":"电信","proviceCode":"620000","type":"taobao","status":"0"}

2.根据搜狐提供的API获取当前的地区：

<script src="http://pv.sohu.com/cityjson?ie=utf-8"></script>

调用该API返回值为：

var returnCitySN = {"cip": "42.91.160.**", "cid": "620000", "cname": "甘肃省"};

$(document).ready(function(){var areaCode = returnCitySN["cid"]; //地区编码var thisIp =  returnCitySN["cip"];  //IPvar areaName = returnCitySN["cname"]; //只能获取到省}

1.根据新浪提供的API获取：

<script src="http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js"></script>

调用该API 返回值：

 var remote_ip_info = {"ret":1,"start":-1,"end":-1,"country":"\u4e2d\u56fd","province":"\u7518\u8083","city":"\u5170\u5dde","district":"","isp":"","type":"","desc":""};

$(document).ready(function(){    alert("当前地区"+remote_ip_info["province"]+"省"+remote_ip_info["city"]+"市"+remote_ip_info["district"]+"区");
｝

注：新浪的暂时不能用了，请大家参考搜狐的或阿里巴巴的
