百度地图 百度坐标 （BD-09）
腾讯地图 火星坐标(GCJ-02)
高德地图 火星坐标(GCJ-02)
微信小程序中使用的是腾讯地图作为底图。因此如果使用百度地图时，需要注意坐标的转换。此类坐标的转换函数在网上都有，这里不做过多解释
准备工作：
1、在做小程序 ---- 路线规划之前，需要准备小程序APPID 以及相应使用地图的KEY值。
2、微信小程序API 之 位置 API wx.getLocation(OBJECT)、wx.chooseLocation(OBJECT)、wx.openLocation(OBJECT)的相应用法：https://www.jb51.net/article/166968.htm
各地图平台-------小程序开发的官方文档
1、高德地图： 微信小程序-路线规划,地图导航功能基于高德地图API官方文档 https://lbs.amap.com/api/wx/guide/route/route
2、百度地图： 微信小程序JavaScript API ----- （百度地图路线规划适用于：android / ios / web,故不适用，排除百度地图）
3、腾讯地图： 微信小程序JavaScript SDK 路线规划 --------- https://lbs.qq.com/qqmap_wx_jssdk/method-direction.html
因此使用高德地图和腾讯地图都可以进行路线规划，通过学习官方文档，了解到其实这两个平台的代码思路是一样的，以下以高德地图为例作详细的说明：
高德地图-路线规划开发：根据官方文档demo进行开发 ：https://lbs.amap.com/api/wx/guide/route/route
注意：数组数据在setData时候的使用方法
var markesName = "markers[" + 0 + "].name"; that.setData({ [markesName]: name, })
注意需要先加载头部的相关文件
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;
效果图：
相关代码：
location.js
