https://developers.weixin.qq.com/miniprogram/dev/api/media/map/MapContext.addGroundOverlay.html 这个API使用没有效果

使用的基础库：2.14 wxml为 <map name="dongshan" longitude="117.431" latitude="23.7144" style="height:100%;width:100%"></map> JS为： this.dongshanmap = wx.createMapContext('dongshan')     this.dongshanmap.addGroundOverlay({       id:1,       src:'/image/2.png',       visible:true,       bounds:{         southwest:{           longitude:117.2841,           latitude:23.5565         },         zIndex:100,         opacity:1,         northeast:{           longitude:117.56,           latitude:23.7726         }       },       success(e){         console.log('dia')       },       fail(e){         console.log('失败')       }     }) 最终不显示 [图片]

申请后什么时候能给通过呀
