Facebook Logout Issues

Question

I have coded a Windows store app that authenticates via Facebook login, the issue I am facing is that whenever I click on the sign out button, I am not signed out completely.

function

fbLogout() {

    client.logout();

    sessionStorage.clear();

    Windows.Storage.ApplicationData.current.localSettings.values[

"User Name"] = null;

    Windows.Storage.ApplicationData.current.localSettings.values[

"User Picture"] = null;

    Windows.UI.Popups.MessageDialog(

"You have been Successfully Logged Out.").showAsync();

    WinJS.Navigation.navigate(

"/pages/login/login.html");

}

everything described in the above function happens but when I reopen the app, it automatically logs me in instead of asking for my credentials.

P.S.: I had checked the keep me logged in button during login, but I don't think that should create an issue after I log out

Answer 1

Hi Himanshu,

Seems still have HTML cache exist. Maybe session, maybe cookie, maybe something else.

I think it should be possible to set a breakpoint when login to Facebook by checking "keep me login" button, you would be able to know where the data goes. Or try to find the documentation on Fackbook for how they manage the user account storage in WinJS.

Probably clean the sessionState object ?
