微信小程序引用Map地图规划制定路径行走并显示路径

先上个效果图：    

//index.wxml


  <map id="map"
    latitude="{{latitude}}"
    longitude="{{longitude}}"
    scale="{{scale}}"
    markers="{{calloutMarkers}}" 
    polyline="{{polyline}}"
    ></map>

//index.wxss


map{
  width: 100%;
  height: 100vh;
}

//index.js


const app = getApp()
// 路径数据
const INIT_POLYLINE = {
  points: [{
      latitude: 40.040129,
      longitude: 116.274968
    },
    {
      latitude: 40.038974,
      longitude: 116.275214
    },
    {
      latitude: 40.038974,
      longitude: 116.275214
    },
    {
