mvc 控制器忽略某些方法

需求：登录信息验证，需要忽略登录注册这些接口的验证，通过给方法加忽略过滤器实现

1.需要忽略的方法加[IgnoreLoginFilter]

2.定义忽略过滤器

public class IgnoreLoginFilterAttribute :Attribute
    {
        

       
    }

3.Global.asax注册全局过滤器

public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }
    }

4.过滤器配置注册过滤器

public class FilterConfig
    {
        public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {
            filters.Add(new HandleErrorAttribute());
            filters.Add(new UserAuthorizationFilter());
        }
    }

5.通过过滤器个数来判断是否需要验证登录信息（这个效果不太好，应该判断是否有忽略验证登录信息过滤器）

public class UserAuthorizationFilter : IAuthorizationFilter
    {
        private static readonly string SID = "SID";
        private static readonly string UID = "UID";

        public void OnAuthorization(AuthorizationContext filterContext)
        {
            var action = filterContext.ActionDescriptor.ActionName;
            var attributes = filterContext.ActionDescriptor.GetCustomAttributes(typeof(IgnoreLoginFilterAttribute),false);
            if (attributes.Length == 0)
            {
                HttpCookie cookie = filterContext.HttpContext.Request.Cookies.Get(SID);
                var cookieSID = filterContext.HttpContext.Request.Cookies[SID];
                var cookieUID = filterContext.HttpContext.Request.Cookies[UID];
                if (cookieSID != null && cookieUID != null)
                {
                    var sessionEnabel = checkSession(cookieSID.Value, cookieUID.Value);
                    
                    if (!sessionEnabel)
                    {
                        filterContext.Result = new JsonResult()
                        {
                            JsonRequestBehavior = JsonRequestBehavior.AllowGet,
                            Data = new ResultInfo(1500, "登录超时")
                        };
                    }
                }
                else
                {
                    filterContext.Result = new JsonResult()
                    {
                        JsonRequestBehavior = JsonRequestBehavior.AllowGet,
                        Data = new ResultInfo(1500, "登录超时")
                    };
                }
            }
        }

        private static bool checkSession(string sid, string uid)
        {
            //服务名：ZJCX.ZJCD.APP.Session.Service
            var resourceUri = string.Format("Session/CheckSessionStatus?sessionID={0}&zjID={1}", sid, uid);
            var result = ZJCX.WebAPI.Connect.WebAPIConnector.Default.Get("ZJCX.ZJCD.APP.Session.Service", resourceUri).Content.ReadAsStringAsync().Result;
            var resultObj = Newtonsoft.Json.JsonConvert.DeserializeAnonymousType(result, new { code = 100 });

            //apiResponse = webApiConnector.Get(serviceName, resourceUri, requestServiceModel2);
            return resultObj.code == 0;
        }
    }

6.方法加过滤器

/// <summary>
        /// 登录接口
        /// </summary>
        /// <param name="mobile"></param>
        /// <param name="code"></param>
        /// <returns></returns>
        [HttpPost]
        [IgnoreLoginFilter]
        public ActionResult Login(string mobile, string code)
        {
            //登录业务代码...
        }
