I have this url:
http://localhost:3256/publicview/details?username=mvcpro4
which works and returns the view with data.
which i would like to be this url:
http://localhost:3256/publicview/details/mvcpro4
which doesnt work, when it gets the controller the username parameter is null.
How do i need to configure the publicview route, so it doesn't break the default routing.
I have these routes in place.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"publicview",
"publicview/details",
new { controller = "publicview", action = "details" }
);
routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
pretty much just like you have already
routes.MapRoute(
"publicview",
"publicview/details/{userName}",
new { controller = "publicview", action = "details", userName=UrlParamter.Optional }
);
Make sure that you call the string parameter userName in your details action so it populates.
or you can just remove the above route and change the parameter to id in your details action so it uses the standard route
be careful of special characters in the url, or .net runtime will kick off and throw exceptions at you.

I have 3 routes total in my code.
If I change the position of 1st with 2nd, then 2nd starts to work but 1st gives 404 error.
Am I doing anything wrong in below code?
This is GET route and works perfectly.
routes.MapRoute(
name: "Default",
url: "{controller}/{action}",
defaults: new {
controller = "Category",
action = "Index",
Category = UrlParameter.Optional
}
);
This is GET route and always give 404 error.
routes.MapRoute(
name: "Default1",
url: "{Category}",
defaults: new {
controller = "Product",
action = "Index",
Category = UrlParameter.Optional
}
);
This is POST route and works perfectly.
routes.MapRoute(
name: "Default_Without_Action",
url: "{controller}/{action}/{Category}",
defaults: new {
controller = "Product",
action = "GetProducts",
Category = UrlParameter.Optional
}
);
test if you put url: "{controller}" and see if this works
routes.MapRoute(
name: "Default1",
url: "{controller}",
defaults: new {
controller = "Product",
action = "Index",
Category = UrlParameter.Optional
}
);
I checked both routes and working fine.
RouteConfig.cs
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
//Route -1
routes.MapRoute(
name: "Default1",
url: "{Category}",
defaults: new { controller = "Product", action = "Index", Category = UrlParameter.Optional }
);
//Route - 2
routes.MapRoute(
name: "Default",
//url: "{controller}/{action}/{id}",
//defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
url: "{controller}/{action}/{Category}",
defaults: new { controller = "Category", action = "Index", Category = UrlParameter.Optional }
);
}
On initial/first request it matches the route-1 and calls the Index Action Method of Product Controller as shown in the picture below. Reason - We defined the defaults parameter for controller Products.
If we remove the defaults parameter from route 1 then on initial/first request route-2 URL pattern matches and Index Action method of Category Controller will be called, Reason - We defined the defaults parameter for controller Category.
Browser response with 404 error only when any request doesn't match with the registered URL pattern.
I would like to add custom default page in Asp.net mvc so instead the page going to Home/Index , i would like to go to Account/Login. I have implement the following but it still go to Home/Index. Please advise what i did wrong. Thank you
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Custom",
url: "{controller}/{Account}/{page}",
defaults: new
{
category = UrlParameter.Optional,
page = 1,
action = "Login"
},
constraints: new
{
controller = "Account"
}
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
Assuming the case that you want the users to be redirected to the login page or a custom page if they are not 'signed-in'.
You could create a filter attribute.
example:
[RequireHttps]
[AuthorizationFilter]
public class MyController : Controller
{
}
public class AuthorizationFilter : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
//do some validation, find if the user is signed-in.
filterContext.Result = new RedirectResult(..Some where in the site..);
}
}
Change your route. The default route is set to /Home/Index
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters*
new { controller = "Home", action = "Index",
id = UrlParameter.Optional }
);
You can change that to be any route you wish
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters*
new { controller = "ControllerName", action = "ControllerActionName",
id = UrlParameter.Optional }
);
replace your default route (the last one) with this
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional }
);
I want to create simple blog engine. For fancy and clean url I'd like to use routing mechanism implemented in MVC4.
I added to RouteConfig.cs this lines:
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "ArticleList",
url: "Articles/{category}/{page}",
defaults: new
{
controller = "Articles",
category = UrlParameter.Optional,
page = 1
});
}
}
And if I write in web browser url:
http://localhost:6666/Articles/SomeCategory/3
I want to move to this controller:
public class ArticlesController : ControllerBase<IHomeService>
{
public ActionResult Index(string category, int page = 0)
{
return View("~/Views/Article/Articles.cshtml");
}
}
with parameters category = "SomeCategory" and page = 1.
All I recieve is
Server Error in '/' Application.
The resource cannot be found.
What is wrong?
routes.MapRoute(
name: "ArticleList",
url: "{controller}/{category}/{page}",
defaults: new
{
category = UrlParameter.Optional,
page = 1,
action = "Index"
},
constraints: new
{
controller = "Articles"
}
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
EDIT
I should have added this to the answer but I was in a hurry:
Register your custom routes first, the more custom the more priority they have.
In the example above using the constraints or hard-coding the route produces the same result. Constraints are more flexible because you can use regex to restrict the controllers/actions/parameters values that your route is for. For instance, if you add a new route that uses the /category/page pattern your can then modify the controller constraint accordingly:
constraints: new
{
controller = #"^(Articles|AnotherController)$"
}
The problem is, you have an optional parameter in the middle of your {controller}/{category}/{page} path. ASP.NET routing has problem with that, because if category is not provided, it has no way to detect that the category is not provided.
To enable attribute routing, call MapMvcAttributeRoutes during configuration. Following are the code snipped.
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes();
}
}
In MVC5, we can combine attribute routing with convention-based routing. Following are the code snipped.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes();
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
It is very easy to make a URI parameter optional by adding a question mark to the route parameter. We can also specify a default value by using the form parameter=value.
Below is my routeconfig.cs file in mvc4 application
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{bizId}",
defaults: new { controller = "Home", action = "Index", bizId = UrlParameter.Optional }
);
routes.MapRoute(
"Outlet",
"Outlet/{bizId}",
new { controller = "Home", action = "Index" },
new { bizId = UrlParameter.Optional }
);
}
When i run the application, i need to enter /Home/Index?bizId=1 or any Id after the localhost port to run my application. It is working fine. But, now as the second route.maproute, I want the url to show as for ex: localhost:49787/Outlet?bizId=1 but this doesnt work. Please help! Thanks in advance
got the fix:
routes.MapRoute(
name: "Outlet",
url: "Outlet/{bizId}",
defaults: new { controller = "Home", action = "Index", bizId = 1 }
);
Route
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Contact",
url: "Contact",
defaults: new { controller = "Home", action = "Contact" }
);
my controller
public class HomeController : BaseController
{
public ActionResult Contact()
{
ViewBag.Message = "Your contact page.";
return View();
}
}
My Global.asax
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
AuthConfig.RegisterAuth();
}
Finally my request url
http://localhost:1234/Contact/
Error on browser
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its
dependencies) could have been removed, had its name changed, or is
temporarily unavailable. Please review the following URL and make
sure that it is spelled correctly.
Requested URL: /Contact/
Version Information: Microsoft .NET Framework Version:4.0.30319;
ASP.NET Version:4.0.30319.18033
What am I doing wrong?
Solution:
Custom route should take the precedence
routes.MapRoute(
name: "Contact",
url: "Contact",
defaults: new { controller = "Home", action = "Contact" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
The Framework always tries to match the URL of the request to a route in the order of the Routes added to the RouteCollection
So you should put the custom routes before the default route,
//Custom route
routes.MapRoute(
name: "Contact",
url: "Contact",
defaults: new { controller = "Home", action = "Contact" }
);
//default route
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
You can use:
routes.MapRoute(
name: "Default",
url: "{*p}",
defaults: new { controller = "Home", action = "Index", p = UrlParameter.Optional }
);
The asterisk indicates that it's a catch-all route. Keep in mind that these routes are extremely greedy, make sure that this stays below any specific routes.
You could also add a route constraint to this route which can determine whether the page exists in the database or something.
