微信小程序中调用腾讯地图获取 jsonp 数据的实例解析

//根据经纬度对象获取位置详细信息

getLocationInfo: function (location){

  let _this = this;   

  var data = {

    location: location.latitude + "," + location.longitude,     

    /*腾讯地图key*/

    key: "************************",

    get_poi: 0 

  };    var url = 'https://apis.map.qq.com/ws/geocoder/v1/?';

  wx.request({

    type: "get",

    dataType: 'jsonp',

    data: data,

    jsonp: "callback",

    jsonpCallback: "QQmap",

    url: url,

    success: function(res) {

      let data = res.data;    #此处data是格式化的字符串，并不是对象        var json = JSON.parse(data);    #把data转换成对象        if (json.status == 0) {

        #此处写业务逻辑

      }

    },

    fail: function(res) {

      console.log(res)

    },

}
