小程序 獲取openid

 wx.login({       

        success: function(res) {                    
               
              if (res.code) {

                var APPID='***************'

                  data: {},

                  method: 'POST',

                  success : function(ret){

                      that.globalData.openid = ret.data.openid;       //獲取openid  （這個地方已經獲取到了，也可以後臺去獲取，這裏就不多說了）
                      
                      wx.getLocation({

                          type: 'wgs84',
