uniapp 实现路线规划

UniApp是一个跨平台的应用开发框架，可以帮助开发者快速地在多个平台上构建应用程序。其中，实现路线规划是一个常见的需求，特别是对于地图类应用或者出行类应用来说，路线规划功能是非常重要的。

首先引入QQMapWX；

};module.exports = QQMapWX;

然后再return中声明

long: '', //初始经度lat: '', //初始纬度end_long: '', //目标经度end_lat: '', //目标纬度scale: 20,qqmapsdk: {}, // 腾讯地图小程序的SDKpolyline: [], // 路线map: null, // 创建的map对象

然后再onReady中创建map对象

onReady() {// 创建map对象this.map = uni.createMapContext('map')},

然后在onLoad中调用相关事件

this.long = this.data.buy_long;this.lat = this.data.buy_lat;this.end_lat = this.data.latit;this.end_long = this.data.longit;this.qqmapsdk = new QQMapWX({key: '33XBZ-7JJK5-6MNII-IFL5W-G7F6S-FWBYD' // 自己申请的key值});this.routePlanning(this.long, this.lat);

其中this.data为缓存的数据

然后是methods中的方法：

// 路线规划routePlanning(long, lat) {let that = thisconsole.log(long, '111');console.log(lat, '111');that.qqmapsdk.direction({mode: 'driving', // 驾车from: { // 起始位置(当前位置)坐标latitude: lat,longitude: long},to: { // 目的地坐标latitude: that.end_lat,longitude: that.end_long,},// 目的地位置坐标success(res) {var coors = res.result.routes[0].polylinevar pl = [] // 点串数组// 坐标解压(返回的点串坐标，通过前向差分进行压缩)var kr = 1000000for (var i = 2; i < coors.length; i++) {coors[i] = Number(coors[i - 2]) + Number(coors[i]) / kr}// 将解压后的坐标放入点串数组pl中for (var i = 0; i < coors.length; i += 2) {pl.push({latitude: coors[i],longitude: coors[i + 1]})}console.log('点串数组', pl)// 设置polyline属性，将路线显示出来，将解压坐标第一个数据作为起点that.polyline = [{points: pl,color: '#367EEF', // 线的填充色width: 3, // 折现宽度borderWidth: 2, // 边线宽度 borderColor: '#5B98FD', // 边线颜色lineCap: 'square', // 线端头showArrow: true, // 沿线路方向显示箭头}]},error(err) {console.log(err);}})},

最后放上view代码

<map id="map" class="map" :latitude="lat" :longitude="long" :show-location="false":polyline="polyline"></map>
