После моего входа в Facebook в Windows Phone 8 токен доступа не обновляется. В чем может быть проблема?
Вот мой FacebookLoginPage.cs:
namespace MyApp.Pages
{
public partial class FacebookLoginPage : PhoneApplicationPage
{
private string message;
public FacebookLoginPage()
{
InitializeComponent();
message = String.Empty;
this.Loaded += FacebookLoginPage_Loaded;
}
protected override void OnBackKeyPress(System.ComponentModel.CancelEventArgs e)
{
NavigationService.GoBack();
base.OnBackKeyPress(e);
}
private async void FacebookLoginPage_Loaded(object sender, RoutedEventArgs e)
{
if (String.IsNullOrEmpty(App.AccessToken))
{
App.isAuthenticated = true;
await Authenticate();
}
}
private FacebookSession session;
private async Task Authenticate()
{
try
{
if (App.FacebookSessionClient.LoginInProgress == true && !String.IsNullOrEmpty(message))
{
App.FacebookSessionClient.LoginInProgress = false;
}
else
{
session = await App.FacebookSessionClient.LoginAsync("user_about_me,read_stream");
App.AccessToken = session.AccessToken;
App.appSettings["accessToken"] = App.AccessToken;
App.appSettings.Save();
App.FacebookId = session.FacebookId;
Dispatcher.BeginInvoke(() => NavigationService.Navigate(new Uri("/Pages/MainPage.xaml?token=" + App.AccessToken, UriKind.Relative)));
}
}
catch (InvalidOperationException)
{
message = "failed";
App.FacebookSessionClient.LoginInProgress = true;
NavigationService.GoBack();
}
}
}
}
В моем App.xml.cs:
public static bool isAuthenticated = false;
public static FacebookSessionClient FacebookSessionClient = new FacebookSessionClient(Constants.FacebookAppId);
