OnActionExecuting造成无限重定向处理会话超时 [英] OnActionExecuting Causing Infinite Redirect for handling Session Timeout

问题描述

我想使用OnActionExecuting我BaseController处理重定向如果用户会话超时登录屏幕。但是它是导致无限重定向我之前也被记录到日志IN-任何人都可以就如何克服这个建议？

I am trying to use OnActionExecuting in my BaseController to handle redirecting to LogOn screen if the User Session is timed out. However it is causing infinite redirects even before I get Logged in- Can anyone advise on how to get round this?

所以在我的基地控制器我有以下几点：

So in my Base controller I have the following:

    protected override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        if (SessionManager.Instance().GetUser() == null) 
        {
            filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary {
                    { "Controller", "Home" },
                    { "Action", "LogOn" }
            });
        }

        base.OnActionExecuting(filterContext);
    }

所以基本上我有一个可以获取/设置用户等一个Session Manager类 - 我有点知道在的getUser问题也将是空的，因为它只是用我的SETUSER法登录已验证后置

So basically I have a Session Manager class that can get/set a user etc - I kind of know the problem in that GetUser will also be null as it is only set using my SetUser method after LogOn has been validated.

不过，而不是我在其他控制器的每一个方法有像检查：

But rather than having every method in my other controllers having a check like:

public ActionResult SomeOtherMethod()
{
     if(SessionManager.Instance().GetUser() != null)
     {

             //Go Do Useful View stuff

     }
     else
     {
          //Redirect To Logon
     }

}

我想在基地控制器使用OnActionExcuting。但由于它是在登录页上运行（因为它应该）我越来越infinte redierct因为的getUser将永远是空？

I wanting to use OnActionExcuting in the Base Controller. But because it is running on the LogOn pages (as it should) I am getting infinte redierct because the GetUser will always be null?

是否有过这样一个更好的办法

Is there a better way off doing this

推荐答案

也许你可以尝试这样的事：

Maybe you can try something like this :

protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
    string controllerName = filterContext.Controller.GetType().Name;
    string actionName = filterContext.ActionDescriptor.ActionName;

    if (SessionManager.Instance().GetUser() == null ) 
    {
        if(!controllerName.Equals(typeof(HomeController).Name,StringComparison.InvariantCultureIgnoreCase)
        || !actionName .Equals("LogOn",StringComparison.InvariantCultureIgnoreCase)))
        filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary {
                { "Controller", "Home" },
                { "Action", "LogOn" }
        });
    }

    base.OnActionExecuting(filterContext);
}
