javascript - How to obtain longitude and latitude through WeChat js and how to receive it in the background
wx.getLocation({
<code> 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
$.ajax({
url:"{:U('home/Share/index')}",
data:{latitude:latitude,longitude:longitude},
type:"POST",
dataType:"json",
success:function(){
}
})
},
})</code>When using ajax to transfer values to the background controller, var_dump($_POST) is a null value. What’s going on?

The writing is correct. As for why you can’t get it, you need to debug your code yourself.
Meat testing method:
Output the received data directly, and then accept the returned object in success.
<code>后台输出：
echo json_encode($_POST);exit();
前台输出：
success:function(msg){
console.log(msg);
}</code>ajax is an asynchronous request and cannot be output directly in the controller
