JavaScript-WeChat JS get latitude and longitude how to send value and how to receive the background

Wx.getlocation ({

    type: 'wgs84', // 默认为wgs84的gps坐标，如果要返回直接给openLocation用的火星坐标，可传入'gcj02'    success: function (res) {        var latitude = res.latitude; // 纬度，浮点数，范围为90 ~ -90        var longitude = res.longitude; // 经度，浮点数，范围为180 ~ -180。        var speed = res.speed; // 速度，以米/每秒计        var accuracy = res.accuracy; // 位置精度                $.ajax({            url:"{:U('home/Share/index')}",            data:{latitude:latitude,longitude:longitude},            type:"POST",            dataType:"json",            success:function(){                            }        })    },})

So with the Ajax value in the background controller,var_dump ($_post) is a null value, what is going on?

The wording is correct, as to why you need to debug your code if you don't get it.

Meat testing Methods:

The direct output receives the data, and then the success returned object is accepted.

后台输出：echo json_encode($_POST);exit();前台输出：success:function(msg){        console.log(msg);           }

Ajax is an asynchronous request and cannot be output directly from the controller
