【问题背景】

小程序转快应用，用户在使用快应用的过程中如果产生了一些授权行为，开发者是否有办法去收集到用户已经授权过的权限呢，从而进行更好管理呢？

【解决方案】

小程序转快应用中是可行的，方法有如下两种：

1、  通过qa.getSystemInfoSync()接口返回的信息。如下图所示：

代码：

  getset2() {const sysInfo = qa.getSystemInfoSync()console.log(sysInfo)}

运行结果：

 "devicePixelRatio":3,"albumAuthorized":false,"cameraAuthorized":false,"locationAuthorized":false,"microphoneAuthorized":false,"notificationAuthorized":false,"notificationAlertAuthorized":false,"notificationBadgeAuthorized":false,"notificationSoundAuthorized":false,"bluetoothEnabled":false,"locationEnabled":true,"wifiEnabled":true,

2、  通过qa.getSetting获取当前用户的设置。

代码：

     qa.getSetting({success(res) {console.log("getSetting success, authSetting = " + JSON.stringify(res.authSetting))}})

运行结果：

 getSetting success, authSetting = {"scope.userLocation":false,"scope.writePhotosAlbum":true,"scope.record":false,"scope.camera":false,"scope.userInfo":false,"scope.address":false,"scope.invoiceTitle":false,"scope.invoice":false,"scope.werun":false}
