获取用户所在城市

获取用户所在城市

搜狐的方法：

https://pv.sohu.com/cityjson?ie=utf-8

<script src="https://pv.sohu.com/cityjson?ie=utf-8"></script>
<script type="text/javascript">
    var Ip = returnCitySN['cip'];
    var cityname = returnCitySN['cname'];
    localStorage.setItem('Ip', Ip);
    localStorage.setItem('cityname', cityname)
</script>

一定要写https！！！http在正式环境出不来，获取不到值，会被搜狐官方阻止
