一、在要检查登入的控制器上继承 CheckLoginController 类
2、 CheckLoginController 类的写法
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc; namespace TaskManagement.Controllers
{
public class CheckLoginController : Controller
{
/// <summary>
/// 实现统一登录验证检查
/// </summary>
/// <param name="filterContext"></param>
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
//如果没有设置Session值那么就跳转到登入页面
//实现登录检查
if (Session["userinfo"] == null)
{
//RedirectResult tourl = new RedirectResult("/Login/UserLogin");
//filterContext.Result = tourl;
ContentResult Cr = new ContentResult
{
Content = string.Format("<script type='text/javascript'>top.location.href='{0}';</script>", "/Login/UserLogin")
};
filterContext.Result = Cr;
}
}
}
}
