Question

在HarmonyOS NEXT开发中requestPermissionsFromUser 用户点了允许了之后，getBundleInfoForSelf返回的BundleInfo里，permissionGrantStates里还是-1 ？

Answer 1

参考以下代码：

async reqPermissionsFromUser(): Promise<number[]> { 
  let context = getContext() as common.UIAbilityContext; 
  let atManager = abilityAccessCtrl.createAtManager(); 
  let grantStatus = await atManager.requestPermissionsFromUser(context, ['ohos.permission.CAMERA']); 
  return grantStatus.authResults; 
} 
// 申请相机权限 
async requestCameraPermission() { 
  let grantStatus = await this.reqPermissionsFromUser() 
  for (let i = 0; i < grantStatus.length; i++) { 
    if (grantStatus[i] === 0) { 
      // 用户授权，可以继续访问目标操作 
      this.userGrant = true; 
    } 
  } 
} 
 
async onPageShow() { 
  await this.requestCameraPermission(); 
}
