這篇文章給大家分享的是有關微信小程序中如何實現高德地圖路線規劃的內容。小編覺得挺實用的,因此分享給大家做個參考,一起跟隨小編過來看看吧。
前言
最近項目中做到相關網約車小程序。需要使用到地圖中的路線規劃,對3種地圖進行了分析。這里稍微做一下總結:
百度地圖 百度坐標 (BD-09)
騰訊地圖 火星坐標(GCJ-02)
高德地圖 火星坐標(GCJ-02)
微信小程序中使用的是騰訊地圖作為底圖。因此如果使用百度地圖時,需要注意坐標的轉換。此類坐標的轉換函數在網上都有,這里不做過多解釋
準備工作:
1、在做小程序 ---- 路線規劃之前,需要準備小程序APPID 以及相應使用地圖的KEY值。
2、微信小程序API 之 位置 API wx.getLocation(OBJECT)、wx.chooseLocation(OBJECT)、wx.openLocation(OBJECT)的相應用法:https://www.jb51.net/article/166968.htm
各地圖平臺-------小程序開發的官方文檔
1、高德地圖: 微信小程序-路線規劃,地圖導航功能基于高德地圖API官方文檔 https://lbs.amap.com/api/wx/guide/route/route
2、百度地圖: 微信小程序JavaScript API ----- http://lbsyun.baidu.com/index.php?title=wxjsapi (百度地圖路線規劃適用于:android / ios / web,故不適用,排除百度地圖)
3、騰訊地圖: 微信小程序JavaScript SDK 路線規劃 --------- https://lbs.qq.com/qqmap_wx_jssdk/method-direction.html
因此使用高德地圖和騰訊地圖都可以進行路線規劃,通過學習官方文檔,了解到其實這兩個平臺的代碼思路是一樣的,以下以高德地圖為例作詳細的說明:

注意:數組數據在setData時候的使用方法
var markesName = "markers[" + 0 + "].name"; that.setData({ [markesName]: name, })
注意需要先加載頭部的相關文件
var amapFile = require('../../libs/amap-wx.js'); var config = require('../../libs/config.js');
文件config.js
var config = { key: '1***********************' } module.exports.Config = config;
效果圖:

這只是個人的一個demo用例。
