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
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:
"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"
}
},
