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

10，返回结果会躲避拥堵，路程较短，尽量缩短时间，与高德地图的默认策略也就是不进行任何勾选一致
* 4，躲避拥堵，但是可能会存在绕路的情况，耗时可能较长
2，距离优先，仅走距离最短的路线，但是可能存在穿越小路/小区的情况

// 默认 10 会 对返回多条路径的方案 按照时间短的
let goodRouter = data.paths.sort((a, b) => {
return a.duration - b.duration
})[0]
that.distance = (goodRouter.distance * 0.001).toFixed(2) + '公里'
that.duration = '大约' + (goodRouter.duration / 60).toFixed(2) + '分钟'
let steps = goodRouter.steps
let points = []
for (var i = 0; i < steps.length; i++) {
var poLen = steps[i].polyline.split(';');
for (var j = 0; j < poLen.length; j++) {
