我有一个UWP应用程序,它使用ReactiveUI来查看视图模型以查看绑定。当用户登录到应用程序时(执行登录命令时),将调用以下方法:
private void RegisterActivityTrackingFunctionality()
{
Container = _container;
Container.Resolve<IDialogService>().IsActive = true;
_dispatcher = Window.Current.Dispatcher;
Window.Current.CoreWindow.PointerPressed += CoreWindow_PointerPressed;
Window.Current.CoreWindow.KeyDown += CoreWindow_KeyDown;
_timer = Observable.Timer(TimeSpan.Zero, TimeSpan.FromSeconds(30)).Subscribe(_ => CheckActivityTime());
}
创建计时器以监视应用程序中的用户活动。如果用户处于非活动状态超过15分钟,则他将从应用程序中注销。基本上,为此目的调用CheckActivityTime()方法:
private void CheckActivityTime()
{
_logger.Info("In a CheckActivityTime Method");
if (Container.Resolve<TokenHolder>().IsActivityTimeElapsed)
{
if (_timer != null)
{
_timer.Dispose();
}
Task.Run(async () => await CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal,
() =>
{
try
{
Container.Resolve<IDialogService>().IsActive = false;
var dialogService = Container.Resolve<IContentDialogService>();
if (dialogService.CurrentContentDialog != null)
{
dialogService.CurrentContentDialog.Hide();
}
var shellViewModel = Container.Resolve<ShellViewModel>();
if (shellViewModel.Router.NavigationStack.Count > 1)
{
shellViewModel.Router.NavigateBack.Execute(null);
}
}
catch (Exception ex)
{
_logger.Error("The unhandled exception occured in UI thread for logout mechanism", ex);
}
}
));
}
}
问题是这样的:当应用程序进入暂停模式时,如果不活动时间超过15分钟,它并不总是注销用户。 任何人都可以向我解释,问题是什么? 也许定时器设置有问题?或者我可能不应该在UI线程上进行注销操作?

您可以做的是将处理程序附加到应用程序的<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<div class="image-text">
<a data-toggle="collapse" aria-expanded="false" class="collapsed">

<div class="collapse" aria-expanded="false" style="height: 0px;"></div>

事件,每次应用程序从暂停状态恢复时调用该事件,然后检查OnResuming
并从那里锁定您的应用程序。
