HarmonyOS beta1中，startRecording会调起用户授权，有什么方法可以拿到用户的授权结果？

参考以下代码：

let permissions: Array<Permissions> =['ohos.permission.WRITE_IMAGEVIDEO','ohos.permission.READ_IMAGEVIDEO']
let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
//requestPermissionsFromUser会判断权限的授权状态来决定是否唤起弹窗
atManager.requestPermissionsFromUser(this.context, permissions).then((data: PermissionRequestResult) => {
  let grantStatus: Array<number> = data.authResults;
  let length: number = grantStatus.length;
  for (let i = 0; i < length; i++) {
    if (grantStatus[i] != 0) {
      //这里是用户拒绝授权，提示用户必须授权才能访问当前页面的功能，并引导用户到系统设置中打开相应的权限
      return;
    }
  }
  //这里是用户同意授权后进行的操作
  console.info(`Success to request permissions from user. authResults is ${grantStatus}.`);
}).catch((err: BusinessError) => {
  console.error(`Failed to request permissions from user. Code is ${err.code}, message is ${err.message}`);
})

需要根据弹框使用添加一下对应permissions
