功能描述：
1.百度地图实现点击地图出现起点，再次点击出现终点（起点终点能拖动）绘制完终点后获取该路的路况并且起点和终点可以拖动实现实时更新（新绘制的路段的）路况
2.地点搜索
效果如下：
关键代码：
new BMapGL.DrivingRouteLine(this.bdMap, {
renderOptions: {
map: this.bdMap,
enableDragging: true,
autoViewport: true,
lineLayerStyle: {
// strokeTextureUrl: null,
showTraffic: true
}
},
onSearchComplete: searchComplete,
onPolylinesSet: () => {
this.drivingTime = drivingTime;
this.drivingDistance = this.convertDistance(drivingDistance);
this.pointsArr = deepClone(pointsArr);
},
});完整代码：
