uniapp小程序使用高德地图api实现路线规划的示例代码
书中枫叶 人气:0路线规划
简介
路线规划常用于出行路线的提前预览，我们提供4种类型的路线规划，分别为：驾车、步行、公交和骑行，满足各种的出行场景。
高德开放平台
本例是驾车路线规划功能和位置选择地图api:chooseLocation
示例：
1、在页面的 js 文件中，实例化 AMapWX 对象，请求进行驾车路线规划。
首先，引入 amap-wx.js 文件（amap-wx.js 从相关下载页面下载的 zip 文件解压后得到）。
import amapFile from "@/libs/amap-wx.js";
然后在 onLoad 实例化 AMapWX 对象
onLoad() {
this.myAmapFunT = new amapFile.AMapWX({
key: 你申请的key
})
},最后生成请求进行驾车路线规划数据
