http://pv.sohu.com/cityjson?ie=utf-8获取外网ip接口

该方法调用返回的外网ip即可获取国家

    //通过ip获取国家
    public static String ipToCountry(String ip){
        String sohu="http://ip.taobao.com/service/getIpInfo.php?ip="+ip;
        String read="";

        Map data = FastJson.getJson().parse(readMap.get("data").toString(), Map.class);
        return data.get("country").toString();
    }

    public static void main(String[] args) {
        String s = IpUtils.ipToCountry("125.47.109.86");
        System.out.println(s);
