在 asp.net mvc4 中设置会话超时?

Setting session timeout in asp.net mvc4?

简而言之,我想在会话 expires.For 时显示登录页面,我在 web.config 中修改了一些细节,如下所示,以便我可以测试逻辑是否 works.But 可悲下面的逻辑没有触发

我的期望是在会话到期时进入 Account Controller 中的 Login Action

还有 authentication sectionsession state 部分的超时有什么区别

<authentication mode="Forms">     
  <forms loginUrl="~/Account/Login"  timeout="1" />
</authentication>

<sessionState mode="InProc" timeout="1" customProvider="DefaultSessionProvider">
  <providers>
    <add name="DefaultSessionProvider" type="System.Web.Providers.DefaultSessionStateProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="DefaultConnection" />
  </providers>
</sessionState>

您可以使用如下自定义属性来实现:

public class SessionTimeOutAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpContext context = HttpContext.Current;

            // check if session supported
            if ( context.Session != null ) {
                if( context.Session["username"] == null ) {
                   context.Response.Redirect ( "~/Account/Login" );
                }
            }
            base.OnActionExecuting(filterContext);
        }
    }

然后您可以将此属性应用于您的控制器或特定操作,例如:

      [SessionTimeOut]
      public class HomeController : Controller
      {

      }

或行动:

      [SessionTimeOut]
      public ActionResult Index()
      {
         return Index();
      }

根据this回答,这些超时属性的基本区别是:

<authentication mode="Forms">     
  <forms loginUrl="~/Account/Login"  timeout="1" />
</authentication>

"The Forms Authentication Timeout value sets the amount of time in minutes that the authentication cookie is set to be valid"

<sessionState mode="InProc" timeout="1" customProvider="DefaultSessionProvider">
  <providers>
    <add name="DefaultSessionProvider" type="System.Web.Providers.DefaultSessionStateProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="DefaultConnection" />
  </providers>
</sessionState>

"The SessionState timeout value sets the amount of time a Session State provider is required to hold data in memory (or whatever backing store is being used, SQL Server, OutOfProc, etc) for a particular session."

您是否在 RegisterGlobalFilters 中注册了授权过滤器?

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
    filters.Add(new AuthorizeAttribute());
} 

并且还为您的控制器配置了 [Authorize] 注释?
