骑行路线规划可以根据起终点获取骑行路线规划数据，并可以通过添加Polyline绘制出骑行路线。

效果图如下：

br: BikingRoute = new BikingRoute();
// 获取骑行路线规划
br.getRouteLines(fromArr, toArr, (res:routeres) => {
      let resultLine: Array<Latlng> = []
      for (let i = 0; i < res.routes.length; i++) {
            // 选取第一个路线规划方案
            let routes = res.routes[i]; 
            // 解析路线
            let line:Array<Latlng> = [];
            line = parseStringToLatLngArray(routes.path);
            resultLine = resultLine.concat(line)
      }
      // 绘制路线
      let polyline:Polyline = new Polyline({
            points: resultLine,
            fillcolor: '#6af',
            width: 10,
            join: SysEnum.LineJoinType.ROUND,
            cap: SysEnum.LineCapType.ROUND,
            isThined: true,
            isGeodesic: true
      });
      this.mapController?.addOverlay(polyline);
}, {})
