.NET形式身份验证问题

Question

我正在MVC.NET中的自定义登录页面上工作。我会检查登录名：

public bool Login(string login, string password, bool persistent)
{
  var loginEntity = this.AdminRepository.GetLogin(login, password);
  if (loginEntity != null)
  {
    FormsAuthentication.SetAuthCookie(login, persistent);

    HttpContext.Current.Session["AdminId"] = loginEntity.AdminId;
    HttpContext.Current.Session["AdminUsername"] = loginEntity.Username;

  return true;
  }

然后，我装饰任何需要使用过滤器属性的管理员访问的控制器：

public override void OnActionExecuting(ActionExecutingContext filterContext)
{
  var ctx = HttpContext.Current;

  // check if session is supported
  if (ctx.Session != null)
  {
    var redirectTargetDictionary = new RouteValueDictionary();

    // check if a new session id was generated
    if (ctx.Session.IsNewSession)
    {
        // If it says it is a new session, but an existing cookie exists, then it must
        // have timed out
        string sessionCookie = ctx.Request.Headers["Cookie"];
        if (((null != sessionCookie) && (sessionCookie.IndexOf("ASP.NET_SessionId") >= 0)) || null == sessionCookie)
        {
          redirectTargetDictionary = new RouteValueDictionary();
          redirectTargetDictionary.Add("area", "Admin");
          redirectTargetDictionary.Add("action", "LogOn");
          redirectTargetDictionary.Add("controller", "Home");

          filterContext.Result = new RedirectToRouteResult(redirectTargetDictionary);
        }
      } else if (SessionContext.AdminId == null) {
        redirectTargetDictionary = new RouteValueDictionary();
        redirectTargetDictionary.Add("area", "Admin");
        redirectTargetDictionary.Add("action", "LogOn");
        redirectTargetDictionary.Add("controller", "Home");

        filterContext.Result = new RedirectToRouteResult(redirectTargetDictionary);
      }
    }
    base.OnActionExecuting(filterContext);
}

我看到登录后，我有两个cookie：

1. ASPXAUTH（有效期将日期设置为“会话结束”（当持续时间为false）或（从现在开始30分钟（当持续时间设置为true时）
2. 和asp.net_sessionid，哪个到期时间始终是“会议结束”

问题：问题是，即使我设置为“持续”选项（即将设置Aspxauth到期时间从现在开始30分钟 - 很好）我的会话[“ adminid”]在我关闭并重新打开浏览器后始终是无效的。当我最初确实将“持续”设置为true并关闭，然后重新打开Browswer窗口时，如何确保我的会话（sessions [“ adminid”]和session [“ adminusername”]）将从cookie中撤出。谢谢

我在这里找到了我的解决方案：是否可以将.aspxauth用于我自己的记录系统？

这就是我所做的：

    public class SessionExpireFilterAttribute : ActionFilterAttribute
{
    /// <summary>
    /// Controller action filter is used to check whether the session is still active. If the session has expired filter redirects to the login screen.
    /// </summary>
    /// <param name="filterContext"></param>
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var ctx = HttpContext.Current;

        // check if session is supported
        if (ctx.Session != null)
        {
            // check if a new session id was generated
            if (ctx.Session.IsNewSession)
            {
                var identity = ctx.User.Identity;

                // If it says it is a new session, but an existing cookie exists, then it must
                // have timed out
                string sessionCookie = ctx.Request.Headers["Cookie"];
                if (((null != sessionCookie) && (sessionCookie.IndexOf("ASP.NET_SessionId") >= 0)) || null == sessionCookie)
                {
                    var redirectTargetDictionary = new RouteValueDictionary();
                    redirectTargetDictionary.Add("area", string.Empty);
                    redirectTargetDictionary.Add("action", "LogOn");
                    redirectTargetDictionary.Add("controller", "User");

                    filterContext.Result = new RedirectToRouteResult(redirectTargetDictionary);
                }

                // Authenticated user, load session info
                else if (identity.IsAuthenticated)
                {
                    var loginRepository = new LoginRepository(InversionOfControl.Container.Resolve<IDbContext>());
                    IAuthenticationService authenticationService = new AuthenticationService(loginRepository);
                    authenticationService.SetLoginSession(identity.Name);
                }
            }
            else if (SessionContext.LoginId == null)
            {
                var redirectTargetDictionary = new RouteValueDictionary();
                redirectTargetDictionary.Add("area", string.Empty);
                redirectTargetDictionary.Add("action", "LogOn");
                redirectTargetDictionary.Add("controller", "User");

                filterContext.Result = new RedirectToRouteResult(redirectTargetDictionary);
            }
        }
        base.OnActionExecuting(filterContext);
    }
}

有到期时间的饼干将写入磁盘。因此，如果cookie尚未过期，则将在下次打开浏览器时仍将登录。

会话cookie仅存储在内存中，并且一旦浏览器关闭，就会丢失。

会话cookie是没有到期日期的cookie。
