MVC URL re-writing - c#

I have Login action method in my home controller like this
[HttpGet]
public ActionResult Login()
{
return View();
}
I am having this Action method as start page of my application, however I want to re-write it like this
www.abc.com/MySite/security/login
I write this attribute after [HttpGet]
[Route("MySite/security/Login")]
Now the problem is,when I am running the application,its giving me error
The resource cannot be found.
This is my RoutConfig
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 = "Login" , id = UrlParameter.Optional }
);
}
How can I fix this issue,Also I am having same name method with HttpPost attribute,should I have to write Rout Attribute on it as well?

This should do the work:
[RoutePrefix("MySite/Security")]
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
[HttpGet]
[HttpPost]
[Route("Login")]
public ActionResult Login()
{
return View("~/Views/Home/Index.cshtml");
}
}
EDITED:
There is one way, but I'm not sure if it's the best way. You need to create another controller called DefaultController like this:
public class DefaultController : Controller
{
//
// GET: /Default/
public ActionResult Index()
{
return RedirectToAction("Login","Home");
}
}
In your RouteConfig.cs, change the 'Default' route with this:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Default", action = "Index", id = UrlParameter.Optional }
);
This should do the job. I'm still trying to find other better ways.

First, you should add custom route on the top of a default route, since you have 2 action methods with different HTTP protocols and want to make custom routing with same action name.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes();
// custom route
routes.MapRoute(
name: "Login",
url: "MySite/{controller}/{action}/{id}",
defaults: new { controller = "Security", action = "Login", id = UrlParameter.Optional }
);
// default route
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home" , action = "Index" , id = UrlParameter.Optional }
);
}
Note that your controller with Login method should be named SecurityController, then you can set attribute routing like this code:
// set all default prefix to /Security path
[RoutePrefix("Security")]
public class SecurityController : Controller
{
[Route("Login")]
public ActionResult Login()
{
return View();
}
}
Additionally, make sure you already registered the route in Global.asax file.
Any improvements & suggestions welcome.

Can't change default action in RouteConfig MVC5

I've a strange behavior of configured route in Route Config in MVC5 app.
So, actually I try to do pretty much easy thing - change default action of a route.
To do that I've changed the defaults of a route, instead of having action = "Index", I've changed it to my required action AddUser (Look at the code below).
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "ManageUser",
url: "{controller}/{action}/{id}",
defaults: new { controller = "ManageUser", action = "AddUser", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
And I've next controller:
[Authorize(Roles ="Admin")]
public class ManageUserController : Controller
{
// GET: ManageUser/AddUser
[HttpGet]
public ActionResult AddUser()
{
return View();
}
}
So, now I expect that whenever user goes by URL: ManageUser/ he'll be redirected to defined default action but it doesn't happen, I just have 404 error. I can fix it simply by adding Index action and then redirect to AddUser, but it doesn't seem right to me. Could somebody help me understand what I've done wrong?
I think, your config should look like this:
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"ManageUser",
"ManageUser/{action}/{id}",
new { controller = "ManageUser", action = "AddUser", id = UrlParameter.Optional }
);
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
The first parameter is the name of the route. Second is the URL, which match URLs that start with ManageUser, and allows for other actions in your ManageUser controller. As you can see, it will default to the AddUser action.
And if you want to call AddUser with paramater, you must call it by full url ManageUser/AddUser/1

C# Asp.Net MVC - Parameter Only Action Request [duplicate]

This question already has answers here:
Routing in ASP.NET MVC, showing username in URL
(2 answers)
Closed 4 years ago.
I have an Asp.Net MVC project whereby we allow our users to have public profiles.
I would like to improve the url, so that it is more friendly, and shorter.
The existing code is as follows -
public class ProfileController : Controller
{
private readonly IUserProfileService _userProfileService;
public ProfileController(IUserProfileService userProfileService)
{
this._userProfileService = userProfileService;
}
public ActionResult Index(string id)
{
//Get users profile from the database using the id
var viewModel = _userProfileService.Get(id);
return View(viewModel);
}
}
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
//Required for the route prefix attributes to work!
routes.MapMvcAttributeRoutes();
routes.MapRoute(
"ProfileUrlIndexActionRemoval",
"Profile/{id}",
new { controller = "Profile", action = "Index" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
The aforementioned code allows the following url to work (based on the default MVC routing) - www.mydomain.com/profile/john-doe
What routing do I need to implement, in order to allow the following url to work instead - www.mydomain.com/john-doe
Thanks.
This is a little tricky as you want the friendly URL in the root of the site while not conflicting with any other routes.
That would mean that if you have any other routes like About or Contact you would need to make sure that are in the route table before the friendly route to avoid route conflicts.
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
//Required for the route prefix attributes to work!
routes.MapMvcAttributeRoutes();
routes.MapRoute(
"ProfileUrlIndexActionRemoval",
"Profile/{id}",
new { controller = "Profile", action = "Index" }
);
routes.MapRoute(
name: "Home",
url: "Home/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "About",
url: "About/{action}/{id}",
defaults: new { controller = "About", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Contact",
url: "Contact/{action}/{id}",
defaults: new { controller = "Contact", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
"Default_Frieldly",
"{*id}",
new { controller = "Profile", action = "Index" }
);
}
}
And finally because the default route will capture all unmatched routes, you will need to take not found profiles into account.
public class ProfileController : Controller {
//...code removed for brevity
public ActionResult Index(string id) {
//Get users profile from the database using the id
var viewModel = _userProfileService.Get(id);
if(viewModel == null) {
return NotFound();
}
return View(viewModel);
}
}
By having the profile controller prefix in the original URL it made it unique so as to avoid route conflicts, but in wanting the root friendly URL, while not impossible, you see the hoops needed to jump through in order to get the desired behavior.
This is how I would do it. Register a route that matches any string after the root slash.
Note that this severely limits the routes you can use for the application since not everything matching /{id} may actually be a user ID, which is why applications will typically prefix the route with /profile or /p.
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapRoute(
name: "UserIdRoute",
url: "{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
public ActionResult Index(string id)
{
//Get users profile from the database using the id
var viewModel = _userProfileService.Get(id);
return View();
}

get specific URI working in asp.net mvc

I aim to get these URIs to work in ASP.NET MVC:
http://localhost:57165/Blas/bla1.xml
http://localhost:57165/Blas/bla2.xml
...
http://localhost:57165/Blas/blan.xml
As you can see the file name can vary and the controller action is ultimately meant to spew out xml file given the file name.
I have this controller:
public class BlasController : Controller
{
// GET: SiteMaps
public ActionResult Index(string fileName)
{
return View();
}
}
and this routing code:
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapRoute(
"Blas",
"{controller}/{fileName}"
);
}
Unfortunately, I get a 404. Is it possible to get this to work?
PS:
I think this is related:
Create a MVC route ending ".js" and returning JavaScript?
First, you should fix your RegisterRoutes method this way:
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapRoute(
name: "FileRoute",
url: "{controller}/{fileName}",
defaults: new { action = "Index" },
constraints: new { fileName = #"^[\w\-. ]+$" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
Second, add this rows to web.config:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
</system.webServer>
P.S. You can process requests to files only at Index action.
Start using Routes which is available in App_Start/RouteConfig.cs
it has some documentation here:
//This is Static Route.
routes.MapRoute(
name: "BlaBla",
url: "/Blas/bla.txt",
defaults: new { controller = "YourController", action = "YourAction" }
);
if you want to send some file to user try an action in controller to send it as ContentResult for you. then Route all of them in RouteConfig.
You can add route config on the method :
[Route("Blas")]
public class BlasController : Controller
{
[HttpGet("{fileName}")]
public ActionResult Index(string fileName)
{
return View();
}
}

Setting route attribute prevent the default route(Controller/Action)

If I set route attribute on my action as mentioned below.
public class AccountController : Controller
{
[Route("Login")]
public ActionResult Login()
{
}
}
My default route is not working that is /Account/Login
I want both url should work
/Login
/Account/Login
Ok, now i get what you want. In your RouteConfig.cs (App_Start folder) you have:
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 }
);
}
You should just add another route AFTER default:
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 }
);
//this is your additional route
routes.MapRoute(
name: "Login",
url: "Login",
defaults: new { controller = "Account", action = "Login"}
);
}
Delete your Route attribute above Login method. Now you will be able to call your method with both urls.
Alternative after your comment. Change your controller like this:
public class AccountController : Controller
{
public ActionResult Login()
{
return Login();
}
[Route("Login")]
public ActionResult Login2()
{
return Login();
}
}

ASP.NET Routing where two controller actions have the same number of parameters

We have a route config like so:
public static void RegisterRoutes(RouteCollection routes) {
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "About",
url: "{controller}/{action}/{aboutId}",
defaults: new { controller = "Home", action = "About" }
);
routes.MapRoute(
name: "Contact",
url: "{controller}/{action}/{contactId}",
defaults: new { controller = "Home", action = "Contact" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
You will notice that there are two routes that have one mandatory extra parameter. The routes About and Contact.
In our app we have two urls
www.myapp.com/Home/About/2 which works fine.
But when we navigate our browser to www.myapp.com/Home/Contact/5 we get the dreaded routing exception:
The parameters dictionary contains a null entry for parameter 'contactId' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Contact(Int32)' in 'RoutingTest.Controllers.HomeController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
If we change the sequence of the routing so that it looks like so:
public static void RegisterRoutes(RouteCollection routes) {
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Contact",
url: "{controller}/{action}/{contactId}",
defaults: new { controller = "Home", action = "Contact" }
);
routes.MapRoute(
name: "About",
url: "{controller}/{action}/{aboutId}",
defaults: new { controller = "Home", action = "About" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
Then the Contact url works but the About url does not.
The HomeController looks like this:
public class HomeController : Controller {
public ActionResult Index() {
ViewBag.Message = "Modify this template to jump-start your ASP.NET MVC application.";
return View();
}
public ActionResult About(int aboutId) {
ViewBag.Message = "Your app description page.";
return View();
}
public ActionResult Contact(int contactId) {
ViewBag.Message = "Your contact page.";
return View();
}
}
What this seems to imply is that two routings cannot have the same number of parameters regardless of the name of the Controller Action. If the two controller actions have a parameter with the same name, then all works fine. I know I can start doing very hacky things to work around this problem such as calling all parameters the same name or giving the actions meaningless parameters to change the number of parameters but I would actually like to know what is happening under the hood.
How do I solve this problem?
The root (no pun intended) of your issue ISN'T that routes can't have the same number of params. They can. The issue is that the routing engine will select the first route that matches the incoming request. Your routes are only different by the defaults, and pattern matching-wise they are exactly the same. So in each and every case you should be hitting the Contact route.
It looks like you are trying to have different routes based on the action. Which I can't actually see why you NEED.
You CAN use the following for that effect.
public static void RegisterRoutes(RouteCollection routes) {
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Contact",
url: "Home/Contact/{contactId}"
);
routes.MapRoute(
name: "About",
url: "Home/About/{aboutId}"
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
However. I HIGHLY recommend against this approach, as your "default" route would be the Contact route. This means that (under Razor) the #Html.ActionLink() and related methods will be...wrong.
Honestly, it should just work perfectly if you actually just use...
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 }
);
}
Specify controller and/or action in a route explicitly to allow routing to pick correct route:
routes.MapRoute(
name: "About",
url: "{controller}/About/{aboutId}",
defaults: new { controller = "Home", action = "About" }
);
You also can add constraints to parameters to distinguish between routes, but it looks like in your case both actions have the same integer parameter.
Couldn't you just delete your custom routes and just reuse the {id} parameter (turn {contactId} and {aboutId} into just "id" in your action code)?
public class HomeController : Controller {
public ActionResult Index() {
ViewBag.Message = "Modify this template to jump-start your ASP.NET MVC application.";
return View();
}
public ActionResult About(int id) {
int aboutId = id;
ViewBag.Message = "Your app description page.";
return View();
}
public ActionResult Contact(int id) {
int contactId = id;
ViewBag.Message = "Your contact page.";
return View();
}
}
