java如何通过IP解析地理位置

java通过IP解析地理位置

在项目开发中,需要在登录日志或者操作日志中记录客户端ip所在的地理位置。

目前根据ip定位地理位置的第三方api有好几个,淘宝、新浪、百度等,这三种其实也有些缺点的:

在此整理一下,便于后期使用。

根据以上使用指南,注册百度账号,成为地图开放平台开发者,获取密钥(AK),根据服务文档使用。

把上边的百度密钥换成你自己的,下边是API返回的json数据格式。

{  
    address: "CN|北京|北京|None|CHINANET|1|None",    #地址  
    content:    #详细内容  
    {  
        address: "北京市",    #简要地址  
        address_detail:    #详细地址信息  
        {  
            city: "北京市",    #城市  
            city_code: 131,    #百度城市代码  
            district: "",    #区县  
            province: "北京市",    #省份  
            street: "",    #街道  
            street_number: ""    #门址  
        },

        }  
    },  
    status: 0    #返回状态码

java获取IP归属地(省、市)

1、添加依赖

	<artifactId>fastjson</artifactId>
	<version>1.2.3</version>
</dependency>

2、工具类代码

    /**

     */
    public static String getIpAddr(HttpServletRequest request) {
        String ip = null;
        try {
            ip = request.getHeader("x-forwarded-for");
            if (StringUtils.isEmpty(ip) || "unknown".equalsIgnoreCase(ip)) {
                ip = request.getHeader("Proxy-Client-IP");
            }
            if (StringUtils.isEmpty(ip) || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

        }
 
        //使用代理,则获取第一个IP地址
        if(StringUtils.isEmpty(ip) ) {
            if(ip.indexOf(",") > 0) {
                ip = ip.substring(0, ip.indexOf(","));
            }
        }
 
        return ip;
    }
 
    /**
     * 根据ip获取归属地
     * @param ip
     * @return
     */
    public static IpAddress getAddress(String ip) {
        String url = "http://ip.ws.126.net/ipquery?ip=" + ip;
        String str = HttpUtil.get(url);
        if(!StrUtil.hasBlank(str)){
            String substring = str.substring(str.indexOf("{"), str.indexOf("}")+1);
            JSONObject jsonObject = JSON.parseObject(substring);
            String province = jsonObject.getString("province");
            String city = jsonObject.getString("city");
            IpAddress ipAddress = new IpAddress();
            ipAddress.setProvince(province);
            ipAddress.setCity(city);
            System.out.println("ip:"+ ip + ",省份:" + province + ",城市:" + city);
            return ipAddress;
        }
        return null;
    }
 
    @Data
    public static class IpAddress{
        private String province;
        private String city;
    }
 
    public static void main(String[] args) {
        System.out.println(getAddress("36.25.225.250"));
    }
 
}

3、测试结果

测试ip:36.25.225.250

返回数据:

ip:36.25.225.250,省份:浙江省,城市:湖州市                  

iptes.IpAddress(province=浙江省, city=湖州市)

总结

以上为个人经验,希望能给大家一个参考,也希望大家多多支持。
