uniapp小程序使用高德地图api实现路线规划

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

		/**
			 *@author ZY
			 *@date 2023/1/9
			 *@Description:生成规划路线
			 *@param {string} start 开始位置
			 *@param {string} end 结束位置
			 *@param {number} strategy 10 默认多策略 策略 https://lbs.amap.com/api/webservice/guide/api/direction#driving
			 *
			 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
			 */
			getPlanningRoute(start, end, strategy = 10) {
				let that = this
				uni.showLoading({
					title: '加载中'
				});
				that.myAmapFunT.getDrivingRoute({
					origin: start,
					destination: end,
					strategy: strategy, //备选方案
					success: function(data) {
						// console.log('所有路径',data)
						if (data.paths && data.paths[0] && data.paths[0].steps) {
							// 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++) {
									points.push({
										longitude: parseFloat(poLen[j].split(',')[0]),
										latitude: parseFloat(poLen[j].split(',')[1])
									})
								}
							}
							that.polyline = [{
								points: points,
								color: strategy === 10 ? '#0ee532' : strategy === 2 ? '#0742d9' :
									'#ee6b06',
								width: 8,
							}]
						}
						uni.hideLoading();
					},
					fail: function(info) { //失败回调
						console.log('路线规划失败')
						console.log(info)
						uni.hideLoading();
						uni.showToast({
							title: '路线规划失败',
							icon: 'error'
						});
					},
				})
			},
