HarmonyOS 使用requestPermissionsFromUser获取权限，弹窗未按照预期弹出

系统弹窗，在整个应用周期内只会弹出一次？即使断点已经走到了return中，也无法弹出。

handleReloadCountChange() {
  if (!this.context) {
    return
  }
  this.xComponentController.setXComponentSurfaceRotation({ lock: true })
  let permissions: Array<Permissions> = ['ohos.permission.CAMERA', 'ohos.permission.MICROPHONE']
  let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
  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) {
        toast('请去设置打开相机以及麦克风权限～')
        return;
      }
    }
    this.getCameraImage()
  }).catch((err: BusinessError) => {
  })
}
