更新记录

1.0.1（2023-05-31）

更新ios适配

1.0.0（2023-04-04）

初始版本

平台兼容性

注意事项

因为是nvue页面所以只能使用手机调试

map地图标点nvue支持更多属性，所以用了nvue，更具情况可换成vue

nvue使用map地图polyline属性重新赋值应先清空在赋值，不然map监测不到不会更新

路线规划使用了高德web服务APi 需要申请web服务key

因为是纯前端调用高德web服务key，相同的地点每次规划可能会有偏差，如有需要可和后端配合，保证路线的一致性

uni.getLocatio获取位置信息ios不支持高精度定位，可把isHighAccuracy属性设为false

工具函数使用说明

    import common from '@/common/js/common.js' //引入js
    //typ==1 获取全部信息
    //typ==2 获取经度
    //typ==3 获取纬度
    common.getLocation(typ) //返回Promise

路线规划核心代码

    //路线规划 默认骑行
    RoutePlanning(type = "bicycling") {
        let origin = this.longitude + ',' + this.latitude
        let destination = Number(this.infodata.store_lon) + ',' + Number(this.infodata.store_lat)
        let destination1 = Number(this.infodata.user_lon) + ',' + Number(this.infodata.user_lat)
        let url = ''
        let edition = null //版本
        if (type == 'bicycling') {
            url = `https://restapi.amap.com/v4/direction/${type}`
            edition = 4
        } else {
            url = `https://restapi.amap.com/v3/direction/${type}`
            edition = 3
        }
        //这里的type == 4为绘制一条路线，可自行修改
        if (this.type == 4) {
            this.getDriverLine(url, edition, origin, destination1, '#02a85c', 1)
        } else {
            this.getDriverLine(url, edition, origin, destination, '#fc6112', 2)
            this.getDriverLine(url, edition, destination, destination1, '#02a85c', 2)
        }
    },

    //路线规划，调用高德地图的api实现规划路线的功能。
