效果图:
一、准备阶段
- 1、在高德开放平台注册成为开发者
- 2、申请开发者密钥(key)。
- 3、下载并解压高德地图微信小程序SDK
高德开放平台:
注册账号(https://lbs.amap.com/)) 申请小程序应用的 key
应用管理(https://console.amap.com/dev/key/app)) -> 我的应用 -> 创建新应用
生成的 key 即可用在程序中
- 下载相关 sdk 文件,导入 amap-wx.js 到项目中:https://lbs.amap.com/api/wx/download
微信小程序:
1.在创建的项目中,新建一个名为 libs 目录,将 amap-wx.js (amap-wx.js 从相关下载页面下载的 zip 文件解压后得到)文件拷贝到 libs 的本地目录下,如下图所示。
2.设置小程序安全通讯域名,为了保证高德小程序 SDK 中提供的功能的正常使用,需要设置安全域名。
登录微信公众平台,在 “设置”->“开发设置” 中设置 request 合法域名,将 https://restapi.amap.com 中添加进去,如下图所示:
- app.json中加入
"permission": {"scope.userLocation": {"desc": "你的位置信息将用于小程序位置接口的效果展示","dowload": "您的文件访问权限用于打开文件"}},
在你需要引用地图的页面的js文件中引入 amap-wx.js 文件。
var amapFile = require('../../../libs/amap-wx.130'); //如:../../libs/amap-wx.js

} from "../../../utils/api/car.js";
