ASP.Net MVC 5 w/identity 2.2.0 Log off not working

问题

I am using a the basic login on a test ASP.Net MVC 5 site (for an internet site).

The login works fine but when I try to logout it doesn't happen. The logout link does call the following controller action:

public ActionResult LogOff()
{
    AuthenticationManager.SignOut();
    return RedirectToAction("Index", "Home");
}

But the user stays logged in. How do I ensure that the user actually gets logged out?

回答1:

I had this problem before, change:

AuthenticationManager.SignOut();

To:

AuthenticationManager.SignOut(DefaultAuthenticationTypes.ApplicationCookie);

Assuming that you are using ApplicationCookie to store your login information.

Better way :

public ActionResult Logout()
{
    SignInManager.AuthenticationManager.SignOut();
    return RedirectToAction("Index", "support", new { area = "" });
}

or you can use injected SignInManager into your controller like this :

public ActionResult Logout()
{
    _signInManager.AuthenticationManager.SignOut();
    return RedirectToAction("Index", "support", new { area = "" });
}

there is no deference.

I had the same problem of not being able to logout. I would stay logged in and only redirect back to the home view. I was using Chrome and I tried it in firefox and ie and didn't have the problem. Then I cleared my cookies in chrome and it all worked fine. It could be a quick and easy first step if other encounter this problem.
