how to route custome url in MVC - model-view-controller

I have return my Controller with attribute routing like below.
[Route("{CourseName}/{CourseCode}")]
public ActionResult getAllProductList(string CourseName,string CourseCode)
{
ViewBag.CourseName = CourseName;
ViewBag.CourseCode = CourseCode;
return View("CoursePage");
}
it works fine. but if there is any ajax method calls (for ex. ../controllername/methodname) from JS then its hitting my above controller/Action instead of "methodname" . Please suggest.
My RouteConfig Code:
routes.MapRoute(
name: "CoursePage",
url: "{CourseName}/{CourseCode}",
defaults: new { controller = "Course", action = "getAllProductList" },
constraints: new { CourseName = "\\d +", CourseCode = "\\d +" }
);

mvc core2.0 routing is not Workin

Here i'm new to mvc core2.0 please help me why my Routing Is not working
My Routing Class
public static class ApplicationRoteProfiler
{
public static void Routeing(IRouteBuilder builder)
{
builder.MapRoute("route1", "", new
{
Controllers = "Department",
Action = "Add",
});
builder.MapRoute("route2", "Department/Add", new
{
Controllers = "Department",
Action = "Index"
});
}
This class file i register in startup.config file
public void Configure(IApplicationBuilder app)
{
app.UseStaticFiles();
app.UseMvc();
app.UseMvcWithDefaultRoute();
app.UseMvc(routes =>
{
ApplicationRoteProfiler.Routeing(routes);
});
}
When i hit my server as http://localhost:1588/Department/Add its should redirect to Department/Index But its hitting Department/Add
Should it be just Controller not Controllers??
builder.MapRoute("route1", "", new { controller = "department", action = "index" });
My 2 cents
You shouldn't use app.UseMvcWithDefaultRoute() and app.UseMvc() at the same time. You only need to pick 1 of them.
I don't see benefits of using a static class to configure routing for MVC. You can just put all the route configurations right there inside UseMvc lamba function. Also I don't think you need to put customized route specifically for your "route1" as it follows the standard MVC routing convention.
app.UseMvc(routes =>
{
// The order of these routes matters!
routes.MapRoute(
name: "route2",
template: "department/add",
defaults: new { area = "", controller = "department", action = "index" });
routes.MapRoute(
name: "default",
template: "{controller=home}/{action=index}/{id?}");
}
You can also return RedirectToAction("index"); inside your Department controller Add method so whenever /deparment/add route is hit, it redirects to /deparment/index, assuming you have the default MVC routing setup, either use the "default" route I put on #2, or use UseMvcWithDefaultRoute(). That way you don't need to create custom routes just for redirecting.
public class DepartmentController : Controller
{
public IActionResult Index()
{
return View();
}
public IActionResult Add()
{
return RedirectToAction("index");
}
}

Why won't my call to a Web API route to the correct method?

I have my first Web API working, but the even when I call it and pass an an id is gets routed to the method that has no arguments.
Here is my controller code:
public class ChartController : ApiController
{
Chart[] _charts = new Chart[]
{
new Chart { Name = "Chart 1" },
new Chart { Name = "Chart 2" },
new Chart { Name = "Chart 3" }
};
// GET api/chart
[Route("api/chart")]
public IEnumerable<Chart> Get()
{
return _charts;
}
// GET api/chart/{id}
[Route("api/chart/{id}")]
public IEnumerable<Chart> Get(int chartId)
{
Chart[] charts = new Chart[]
{
Charts.Database.ChartsDB.GetChart(chartId)
};
return charts;
}
}
Here is my routing in my global.asax
RouteTable.Routes.MapHttpRoute(
name: "ChartApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = System.Web.Http.RouteParameter.Optional }
);
This is my request uri
http://localhost:42311/api/chart
And the results
[
{
"Name": "Chart 1"
},
{
"Name": "Chart 2"
},
{
"Name": "Chart 3"
}
]
When I change the uri to
http://localhost:42311/api/chart/1
I get the same results, as both calls are routed to
public IEnumerable<Chart> Get()
What am I doing wrong?
Please note that WebApi works based on reflection this means that your curly braces {vars} must match the same name in your methods.
Therefore to match this api/chart/{id} your method needs to be declare like this:
[Route("api/chart/{chartId}"), HttpGet]
public IEnumerable<Chart> Get(int chartId)
return userId;
}
Where the parameter {id} was replaced by chartId.
Another option can be:
[Route("api/chart/{id}"), HttpGet]
public IEnumerable<Chart> Get(int id)
return userId;
}

Wrong route selected in ASP.NET MVC 3

Could please someone shed some light into this issue, it drives me crazy!
The routes:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"DefaultOrderingRoute", // Route name
"{controller}/{action}/{id}/{slug}", // URL with parameters
new { controller = "Order", slug = UrlParameter.Optional }, // Parameter defaults
new { controller = "^Order$" }
);
routes.MapRoute(
"DefaultImageRoute", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Image", }, // Parameter defaults
new { controller = "^Image$" }
);
routes.MapRoute(
"FooterRoute", //route for invoking actions for the Footer
"{controller}/{action}", // URL with parameters
new { controller = "Footer", }, // Parameter defaults
new { controller = "^Footer$" }
);
routes.MapRoute(
"DefaultDealRoute", // Route name
"{city}/{category}/{id}/{slug}", // URL with parameters
new { category = Deals.Globals.Global.CATEGORY_ALL_NAME, controller = "Deal", action = "Details", slug = UrlParameter.Optional }, // Parameter defaults
new { controller = "^Deal$", id = #"\d+" }
);
routes.MapRoute(
"DealRouteForCategory", // Route name
"{city}/{category}", // URL with parameters
new { city = "", category = Deals.Globals.Global.CATEGORY_ALL_NAME, controller = "Deal", action = "Details" }, // Parameter defaults
new { controller = "^Deal$" }
);
}
I have add a reference to routedebugger to see what is going on under the hood.
So for the selected URL:
http://my.SERVER.IP/VirtualDirectoryName/Order/PayPalNotify/9/blabla
the URL debugger shows the following:
AppRelativeCurrentExecutionFilePath: ~/Order/PayPalNotify/9/adfaf (exactly what i have expected)!!!
The debugger also shows that routes DefaultOrderingRoute and DefaultDealRoute are matched (this i didn't expect! since i have constraints on the routes!!).
It also shows that the matched route is:
Matched Route: {controller}/{action}/{id}/{slug}
with route data:
controller: Deal
action: Details
id: 9
slug: adfaf
city: Athens
category: All
How is this possible?? What am i doing wrong?
PS. I've noticed that by reissuing the URL the correct route gets executed!!!
Mystery solved: i was doing something very bad(!):
in Session_Start() i had somewhere code which did the following (amongst others)
Session_Start()
{
// code snippet out for brevity
//setup the city route values
HttpContext.Current.Request.RequestContext.RouteData.Values["city"] = cityToBeginWith;
//setup the category route values
HttpContext.Current.Request.RequestContext.RouteData.Values["category"] = Deals.Globals.Global.CATEGORY_ALL_NAME;
//setup the controller route values
HttpContext.Current.Request.RequestContext.RouteData.Values["controller"] = "Deal";
//setup the action route values
HttpContext.Current.Request.RequestContext.RouteData.Values["action"] = "Details";
}
This caused the selection of the "false" route... very bad!!

ASP MVC 3 switching language with ActionLink

In an ASP MVC 3 project i want to enable language switching.
The routing is defined like this:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"DefaultWithLanguage", // Route name
"{language}/{controller}/{id}/{slug}", // URL with parameters
new { language = "en", controller = "Front", action = "Details", id = UrlParameter.Optional, slug = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
Trying to switch languages (in _Layout.cshtml) works like this:
<li>#Html.ActionLink("Spanish", ViewContext.RouteData.Values["action"].ToString(), ViewContext.RouteData.Values["controller"].ToString(), new { language = "es" })</li>
Instead of getting a URL like the following (after having selected Spanish)
.../es/ControllerName/ActionName
i 'm getting this:
.../ControllerName/ActionName?Length=11
If i set the ActionLink to the following (notice the last null parameter):
<li>#Html.ActionLink("Spanish", ViewContext.RouteData.Values["action"].ToString(), ViewContext.RouteData.Values["controller"].ToString(), new { language = "es" }, null)</li>
i get this:
.../ControllerName/ActionName?language=es
What am i missing?
Thanks in advance!
There are some issues with your routes registration DefaultWithLanguage route registration. It doesn't allow you to specify the {action}. This means that this route will only match a Details action (since you have specified it in the default values). Another issue is that you made the {id} parameter optional. But that's impossible. Only the last parameter of a route can be optional. In your case it is followed by a {slug} parameter.
So one possibility is the following:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"DefaultWithLanguage",
"{language}/{controller}/{action}/{id}",
new
{
language = "en",
controller = "Front",
action = "Details",
id = UrlParameter.Optional
}
);
}
and then:
#Html.ActionLink(
"Spanish",
ViewContext.RouteData.GetRequiredString("action"),
ViewContext.RouteData.GetRequiredString("controller"),
new { language = "es" },
null
)
If you wanted to add a {slug} parameter then your {id} can no longer be optional:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"DefaultWithLanguage",
"{language}/{controller}/{action}/{id}/{slug}",
new
{
language = "en",
controller = "Front",
action = "Details",
slug = UrlParameter.Optional
}
);
}
and then:
#Html.ActionLink(
"Spanish",
ViewContext.RouteData.GetRequiredString("action"),
ViewContext.RouteData.GetRequiredString("controller"),
new {
language = "es",
id = ViewContext.RouteData.GetRequiredString("id")
},
null
)
This is a follow up to Darin's answer.
I want to have routes like this:
.../en/ControllerName/Id
.../en/ControllerName/Id/Slug
.../en/ControllerName
This last route causes the problem (see the answer of Darin). The "hack" to keep getting this routes is to define also another route (the second named DefaultWithLanguageWithoutId) :
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"DefaultWithLanguage", // Route name
"{language}/{controller}/{id}/{slug}", // URL with parameters
new { language = "en", controller = "Front", action = "Details", id = UrlParameter.Optional, slug = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"DefaultWithLanguageWithoutId", // Route name
"{language}/{controller}", // URL with parameters
new { language = "en", controller = "Front", action = "Details"} // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
This is causing the code to be adjusted in the master page to the following
<li>#Html.ActionLink("Deutsch", ViewContext.RouteData.Values["action"].ToString()
, ViewContext.RouteData.Values["controller"].ToString(), new { language = "de"
, id = ViewContext.RouteData.Values["id"]!=null ? ViewContext.RouteData.Values["id"].ToString():null }, null)</li>
<li>#Html.ActionLink("English", ViewContext.RouteData.Values["action"].ToString()
, ViewContext.RouteData.Values["controller"].ToString(), new { language = "en"
, id = ViewContext.RouteData.Values["id"] != null ? ViewContext.RouteData.Values["id"].ToString() : null }, null)</li>
Works perfect!
The only "drawback" is the fact that there is some code involved (i would have liked to avoid) in the view, but i think it is worth since it is very simple!

ASP.NET MVC 3.0 Routing behaviour

I have controller BlogController with a couple of actions:
1)Index(string id) - show all posts/show single post if parameter id specified
2)New() - add new post
3)Delete() - delete post
4)And some more another actions
So if i type in browser mysite/blog i could see all posts if i type mysite/blog/postnameid i want to see single post.
the problem is when i type mysite/blog/postnameid it is not working (The resource cannot be found.), but if i type mysite/blog/index/postnameid this way it is working. How could i make mysite/blog/postnameidto work as well.
Here is my blog route in global.ascx
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRouteLowercase(
"Blog", // Route name
"Blog/{action}/{id}", // URL with parameters
new { controller = "Blog", action = "Index" } // Parameter defaults
);
routes.MapRouteLowercase(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
Than if i change it like that
routes.MapRouteLowercase(
"Blog", // Route name
"Blog/{id}", // URL with parameters
new { controller = "Blog", action = "Index" } // Parameter defaults
);
the mysite/blog/postnameid working but all another actions like New(), Delete() stop working after that (The resource cannot be found. )
UPDATE:
I forgot to mention that id is sting, not int. so from #Darin answer i changed new { id = #"\w+" } to new { id = #"\d+" } and all seams to be working but now when i typed blog/new for example, it is routing to show/new insteard blog/new
It is a bad idea and against RESTful conventions to have a single controller action that do 2 things and of course violating the single responsibility principle (list all posts if no id is specified and show a given post if an id is specified). The correct way would be to have the following:
/blog => BlogController/Index => list all posts
/blog/123 => BlogController/Show(id = 123) => show details of a given post
/blog/new => BlogController/New() => start writing a new post
/blog/delete/123 => BlogController/Delete(id = 123) => delete given post
which would be achieved with the following routes:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Blog",
"blog/{id}",
new { controller = "Blog", action = "Show" },
new { id = #"\d+" }
);
routes.MapRoute(
"Default",
"blog/{action}/{id}",
new { controller = "Blog", action = "Index", id = UrlParameter.Optional }
);
}
Notice the required route constraint on the first definition which indicates what form all ids must be so that the routing engine could disambiguate between an id and an action name.
This being said if you want to violate the 2 principles I mentioned earlier and have the routes you want a slight adaptation would be required:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Blog",
"blog/{id}",
new { controller = "Blog", action = "Index" },
new { id = #"\d+" }
);
routes.MapRoute(
"Default",
"blog/{action}/{id}",
new { controller = "Blog", action = "Index", id = UrlParameter.Optional }
);
}
Now:
/blog => BlogController/Index(id = null) => list all posts
/blog/123 => BlogController/Index(id = 123) => show details of a given post
/blog/new => BlogController/New() => start writing a new post
/blog/delete/123 => BlogController/Delete(id = 123) => delete given post
