I'm having an issue that is driving me nuts.
I have an MVC 4 WebAPI application that has several Areas defined.
My Jobs Area Send controller (SendController.cs) is defined like so:
namespace TargetAPI.Areas.Jobs.Controllers
{
public class SendController : ApiController
{
[HttpPost]
public HttpResponseMessage Index(SendRequest req)
{
try
{
//blah blah
}
catch (Exception ex)
{
//blah blah
}
}
}
}
My Jobs Area Registration (JobsAreaRegistration.cs) is defined like so:
namespace TargetAPI.Areas.Jobs
{
public class JobsAreaRegistration : AreaRegistration
{
public override string AreaName
{
get
{
return "Jobs";
}
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Jobs_long",
"Jobs/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional },
new[] { "TargetAPI.Areas.Jobs.Controllers" }
);
}
}
}
My RouteConfig.cs says:
namespace TargetAPI
{
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 },
namespaces: new string[] { "TargetAPI.Controllers" }
);
}
}
}
When I run the route debugger on it I get:
(source: boomerang.com)
But when I try to post to the URL "Jobs/Send" I get:
The controller for path '/Jobs/Send' was not found or does not implement IController.
I've tried so many iterations and combinations my head is spinning. Any ideas?
Thanks!
Turns out the WebAPI does NOT handles Areas! Imagine my surprise. So I found a GREAT post http://blogs.infosupport.com/asp-net-mvc-4-rc-getting-webapi-and-areas-to-play-nicely/. Now I am moving forward.
In addition to not supporting Areas (because MapHTTPRoute doesn't have namespace support), The API controller must use MapHttpRoute, not MapRoute as in this example (after removing area):
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
Note the absence of {action}, the Method's are not Actions, put are taken from the HTTP request: Get, Head, etc...
I had the same problem, the solution was simple: I forgot to add files _ViewStart.cshtml and _Layout.cshtml, and can help you

I just want to customize routes in asp.net mvc ,
This is a blog website and I want to access controller methods using
wwww.sitename.com/blog/{blogtitle}
www.sitename.com/blog/{action}
Blog Controller
public class BlogController : Controller
{
public ActionResult Index(string title)
{
return View();
}
[Route("post-blog")]
[HttpPost]
public ActionResult Post(Blog blog,HttpPostedFileBase blogimage)
{
//some coe
}
[Route("post-blog")]
public ActionResult Post()
{
if (Request.Cookies["userInfo"]==null)
{
return Redirect("/login");
}
return View();
}
}
Here is route Config
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
//routes.Canonicalize().Www();
routes.Canonicalize().Lowercase();
routes.MapMvcAttributeRoutes();
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "freelogomaker", id = UrlParameter.Optional }
);
}
But I am unable to hit action name "Index" using www.site.com/blog/titlename
But I can access "post-blog" using www.site.com/blog/post-blog
Please help me I am beginner in asp.net mvc routing.
Add your parameter to the route attribute within {} brackets to indicate that it should be read from the URL, and not from something else (such as POST body, dependency injections, etc)
[Route("{title}")]
public ActionResult Index(string title)
{
return View();
}
I also like to add the RoutePrefix attribute to the controller to make it a bit clearer.
[RoutePrefix("blog")]
public class BlogController : Controller
I am working on a new project and i have decided to use attribute routing alone. This is my RouteConfig file:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes();
//routes.MapRoute(
// name: "Default",
// url: "{controller}/{action}",
// defaults: new { controller = "HomeController", action = "Index", id = UrlParameter.Optional }
//);
}
This is my controller:
[RoutePrefix("home")]
public class HomeController : Controller
{
[Route]
[Route("~/")]
public ActionResult Index()
{
var status = HttpContext.User.Identity.IsAuthenticated;
ViewBag.Title = "Home Page";
return View();
}
[Route("test")]
public ActionResult Test()
{
return View();
}
}
I've realised that typically all my attributes are working but i want the Index method to run on application start. Say https://example.com and then the Index method is fired as if i entered the url https://example.com/home/index. I get a blank space when i do say https://example.com.
Can anyone please help me understand why i get a blank space and also how to set the default application start route using attribute routing? I've been surfing the internet for hours but i can't lay my hands on anything.
In your case you should still set a default route. That way the site knows where to start. From there everything else should work as you intended.
public static void RegisterRoutes(RouteCollection routes) {
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes();
routes.MapRoute(
name: "Default",
url: "{action}",
defaults: new { controller = "Home", action = "Index" }
);
}
Here is my Home Controller.
public class HomeController : FrontOfficeControllerBase {
public HomeController() {
}
public ActionResult Index() {
...
return View();
}
}
Other than that this keeps my route config clean as I use attribute routing everywhere else.
Try this:
[RoutePrefix("home")]
public class HomeController : Controller
{
[Route("index")]
[Route("~/", Name = "default")]
public ActionResult Index()
{
...
}
...
}
I tried write code what is working in MVC 4 using VS2012.
RouteConfig.cs
namespace MvcApplication2012
{
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "SayHello",
url: "hello",
defaults: new { controller = "hello" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
}
IController.cs
namespace MvcApplication2012.Controllers
{
public class HelloController : IController
{
public void Execute(System.Web.Routing.RequestContext requestContext)
{
requestContext.HttpContext.Response.Write("Hello, world!");
}
}
}
This code works fine in MVC 4 using VS2012, but not work in MVC 5 using VS2015.
What is defference? Why it not work?
Returns error
enter image description here
Bassically I found answer, I forgot set class HelloController as public:( But now all is works
I have a TextObject controller, which is meant to be accessed by "~/umt/text/{action}/{id?}", as defined in the controller using attribute routing, but the action link:
#Html.ActionLink("Index", "Index", "TextObject")
ignores Attribute Routing and uses the Conventional routing definitions, producing ~/TextObject/ instead of the desired ~/umt/text/
the TextObjectController:
[Authorize]
[RouteArea("umt")]
[RoutePrefix("text")]
[Route("{action=index}/{id?}")]
public class TextObjectController : Controller
{
.....
public async Task<ActionResult> Index()
{
return View(await db.TextObjects.ToListAsync());
}
.....
}
My route config:
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
//Enable Attribute Routing
routes.MapMvcAttributeRoutes();
AreaRegistration.RegisterAllAreas();
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
Is there any additional configuration required on the controller to make the action link work or does it not work with attribute routing?
I'd like to keep it simple, and it routes correctly going directly through the url, but the ActionLink helper seems to not like something about it.
I can't see that you specify your defauld area it RouteConfig so your action link should look like:
#Html.ActionLink("TextObject", "Index", "Index", new { area = "umt" }, null)
I have a controller for my entire database, the code is below:
public class YogaController : DbDataController<Yoga.Models.YOGAEntities>
{
public YogaController()
{
}
public IQueryable<Yoga.Models.Action> GetActions(int BugId)
//GetActions retrieves "actions" table from the db, not Actions in MVC term
{
return DbContext.Actions.Where(x => x.FK_BugsID == BugId);
}
public IQueryable<Yoga.Models.Label> GetRequiredLabels()
{
return DbContext.Labels.Where(x => x.IsRequired == true);
}
public IQueryable<Yoga.Models.Role> GetRoles()
{
return DbContext.Roles;
}
public IQueryable<Role> GetRoles2() //TODO: finish this
{
return DbContext.Roles.Where(x => x.RoleID == 1);
}
public IQueryable<Tag> GetTags(int actionid)
{
return DbContext.Tags.Where(x => x.J_Tags.Any(y => y.FK_ActionID == actionid));
}
}
As you can see I have multiple IQueryable in one controller, each querying a different table. Is it something that's forbidden? Because when I go to localhost/api/Yoga/GetActions or localhost/api/Yoga/GetRequiredLabels I get the error message:
Multiple actions were found that match the request:
System.Linq.IQueryable`1[Yoga.Models.Label] GetRequiredLabels() on type Yoga.Controllers.YogaController
System.Linq.IQueryable`1[Yoga.Models.Role] GetRoles() on type Yoga.Controllers.YogaController
System.Linq.IQueryable`1[Yoga.Models.Role] GetRoles2() on type Yoga.Controllers.YogaController
When I disable all but one IQueryable, the results came out fine.
I have googled for similar issues and checked my routing settings, there are no conflicts in controller path and names.
My Routes (default generated):
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
//routes.MapRoute(
// name: "Default",
// url: "{controller}/{action}/{id}",
// defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
Any ideas?
MVC4 is probably matching your HTTP Verb (Get) against all methods with names starting with 'Get' and no parameters. Try forcing the action name:
[ActionName("GetRequiredLabels")]
public IQueryable<Yoga.Models.Label> GetRequiredLabels()
...
[ActionName("GetActions")]
public IQueryable<Yoga.Models.Action> GetActions(int BugId)
... // etc
EDIT:
Based on the routes you pasted and your controller, I think your routes should be:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
i.e. it should have the {action} in there. The default MVC4 route would work if you only had a single 'Get' method. Since you have multiple, you'll have to force it to pick the action based on the route.
