asp.net - AuthenticationManager 引用丢失

Question

关注 this问题，缺少方法的引用文献 SignOut()和 SignIn() :

private async Task SignInAsync(User user, bool isPersistent)
{
    AuthenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie);
    var identity = await UserManager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie);
    AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, identity);
}

有人知道如何解决吗？

Answer 1

您是如何定义 AuthenticationManager 属性的？通常它应该如下所示:

private IAuthenticationManager AuthenticationManager
{
  get
  {
    return HttpContext.GetOwinContext().Authentication;
  }
}

有了它，您应该能够调用 SignOut 和 SignIn 方法。
