Asp.Net-Mvc全局检测登录

创建一个新的类用于检测

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using ProcuracyRoom.Dll;

namespace ProcuracyRoom.Web.WebCode
{ 
    public sealed class LoginFilterAttribute:ActionFilterAttribute
    {       
      
        static string[] FreeModules = {"test","public", "mobile" };//整个Controller可以不登录直接使用
        static string[] FreeUrl = { "/home/login", "/home/logout" };//Controller里面的Action可以使用
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {            
            string path = filterContext.RequestContext.HttpContext.Request.Url.LocalPath.ToLower();            
            string action = filterContext.ActionDescriptor.ActionName ;
            string controller = filterContext.Controller.GetType().Name.ToLower();         
            if (FreeModules.Any(t=>controller.StartsWith(t))) return;
            if(FreeUrl.Any(t=>path.Contains(t)))return;
            MyUser user = MyWebApp.currentUser;          
            if(user==null )
            {
               filterContext.HttpContext.Response.Redirect(MyWebApp.LoginUrl);               
            }            
        }
    }
}

然后在Global.asax.cs文件中加入：（如果没有此文件 需自己创建）

 GlobalFilters.Filters.Add(new LoginFilterAttribute());
