OnActionExecuting循环MVC

Question

我正在使用动作过滤器在我的项目中做一项工作。我想这样做，如果用户的ip等于我的ip，它将转到索引，而不是看到登录页面。如果它的ip是不同的，我想把他重定向到登录页面。在登录页面中，我询问密码和id。我有一个问题，重定向到登录页面。这是我的代码，我如何修复这个循环呢？

过滤器

public class IntranetAction : ActionFilterAttribute
{
    private const string LOCALIP = "192.168";

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var request = filterContext.RequestContext.HttpContext.Request;

        string ip1 = request.UserHostAddress;
        string shortLocalIP;
        if (ip1 != null && ip1.Contains("."))
        {
            string[] ipValues = ip1.Split('.');
            shortLocalIP = ipValues[0] + "." + ipValues[1];
        }
        else
        {
            shortLocalIP = "192.168";
        }

        //var ip2 = request.ServerVariables["LOCAL_ADDR"];
        //var ip3 = request.ServerVariables["SERVER_ADDR"];

        if (shortLocalIP != LOCALIP)
        {

            filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new
            {
                controller = "Login", //TODO - Edit as per you controller and action
                action = "User"
            }));

        }
        else
        {
            filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new
            {
                controller = "Home", //TODO - Edit as per you controller and action
                action = "Index"
            }));
        }

        base.OnActionExecuting(filterContext);
    }
}

登录控制器

public class LoginController : Controller
{
    // GET: Login
    [IntranetAction]
    public ActionResult User()
    {         
        return View();
    }


    public void checkAuthentication(UserLoginInfo loginInfo)
    {         
        bool isAuthenticated = new LdapServiceManager().isAuthenticated(loginInfo);
        if (isAuthenticated)
        {

            //HttpContext.Response.Redirect("/Home/Index");
            Response.Redirect("/Home/Index");
            Response.End();
        }
        else
        {
            Response.Redirect("/", false);
        }         
    }
}

这是我的filter类中的循环。shortLocalIP不等于我的LOCALIP，它转到我的登录页面，但它转到inf循环

我认为你需要在登录控制器中添加另一个视图Index。

如果user ip和your ip相等，则转到Home/Index，否则转到Login/Index。

您的startup视图将是Login/User，其中将放置您的filter。

public class IntranetAction : ActionFilterAttribute
{
    private const string LOCALIP = "192.168";

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var request = filterContext.RequestContext.HttpContext.Request;

        string ip1 = request.UserHostAddress;
        string shortLocalIP;
        if (ip1 != null && ip1.Contains("."))
        {
            string[] ipValues = ip1.Split('.');
            shortLocalIP = ipValues[0] + "." + ipValues[1];
        }
        else
        {
            shortLocalIP = "192.168";
        }

        //var ip2 = request.ServerVariables["LOCAL_ADDR"];
        //var ip3 = request.ServerVariables["SERVER_ADDR"];

        if (shortLocalIP != LOCALIP)
        {

            filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new
            {
                controller = "Login", //TODO - Edit as per you controller and action
                action = "Index"
            }));

        }
        else
        {
            filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new
            {
                controller = "Home", //TODO - Edit as per you controller and action
                action = "Index"
            }));
        }

        base.OnActionExecuting(filterContext);
    }
}
