URL Routing with an MVC - c#

I am making a website that displays a bunch of articles. It is built off a MVC I want to be able to search for articles by day and then by an ID number via url.
If the domain name is website.com, I'm trying to figure out how to make routes so that website.com/yyyymmdd hits a specific controller+method and displays all the articles for that day and website.com/yyyymmdd/111 searches that day's articles for article #111.
The issue I'm having is that all the tutorials for routing within an MVC assume I will specify the controller and method in the URL. They show something like:
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = "" });
}
If anybody could suggest a way to automatically make "website.com/yyyymmdd/111" use a specified controller and method, that'd be amazing. Thanks in advance!
EDIT:
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapRoute(
"Today",
"{date}/{id}",
new { controller = "Articles", action = "Index", date = DateTime.Today.ToString("yyyyMMdd"), id = UrlParameter.Optional });
}
I've done this as my route and my method is as follows:
public ActionResult ArticlesByDate(string date, int id)
{
if(id > 1)
{
return View(Contact());
}
else
{
return View(About());
}
}
I hope I am understanding your guys' suggestions, but this is giving me a "Resource can not be found" error when i try to navigate to: "http://localhost:52159/20160908/2"

One way this can be solved by using the date as a parameter to the action.
Your action would look like
public ActionResult Index(string articleDate,string id) ...
The your route definition would be something like
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapRoute(
"Default",
"{controller}/{action}/{articleDate}/{id}",
new { controller = "Home", action = "Index",articleDate=DateTime.Today.ToString("yyyyMMdd"), id = "" });
}
Then you can take it from there

Second route for default mvc routing mechanism.
First route is for articles.Controller and action value is static. You can change date and id values for website.com/20160911/111 , website.com/20160912/112 etc.
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapRoute(
name: "Articles",
url: "{date}/{id}",
defaults: new { controller = "Articles", action = "Info"});
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional });
}
public class ArticleController : Controller {
public ActionResult Info(string date, int id){
return View();
}
}
you cant redirect two view in an action. Use one view and partial views within.
for example
Info.cshtml
#if(id > 1)
{
#Html.Partial("_Contact")
}
else
{
#Html.Partial("_About")
}

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();
}

MVC4 Custom Routing - Validating Personalized Urls

I have a website in MVC4 that I am developing that requires some custom routing. It is a simple website with a few pages. For example:
/index
/plan
/investing
... etc.. a few others
Through an admin panel the site administrator can create "branded" sites, that basically mirror the above content, but swap out a few things like branded company name, logo etc. Once created, the URLs would look like
/{personalizedurl}/index
/{personalizedurl}/plan
/{personalizedurl}/investing
... etc... (exact same pages as the non branded pages.
I am validating the personalized urls with an action filter attribute on the controller method and returning a 404 if not found in the database.
Here is an example of one of my actions:
[ValidatePersonalizedUrl]
[ActionName("plan")]
public ActionResult Plan(string url)
{
return View("Plan", GetSite(url));
}
Easy-peasy so far and works pretty well with the following routes:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Admin",
url: "Admin/{action}/{id}",
defaults: new { controller = "Admin", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{action}",
defaults: new { controller = "Default", action = "Index" }
);
routes.MapRoute(
"Branded", // Route name
"{url}/{action}", // URL with parameters
new { controller = "Default", action = "Index" } // Parameter defaults
);
/*
routes.MapRoute(
"BrandedHome", // Route name
"{url}/", // URL with parameters
new { controller = "Default", action = "Index" } // Parameter defaults
);
*/
}
The problem I currently have is with the bottom commented out route. I'd like to be able to go to /{personalizedurl}/ and have it find the correct action (Index action in default controller). right now with the bottom line commented out, I get a 404 because it thinks its an action and its not found. When I un-comment it, the index pages, work however the individual actions do not /plan for example because it thinks its a pUrl and can't find it in the database.
Anyway, sorry for the long question. Any help or suggestions on how to set this up would be greatly appreciated.

The problem is that MVC will use the first matching url and since the second route is:
routes.MapRoute(
name: "Default",
url: "{action}",
defaults: new { controller = "Default", action = "Index" }
);
and that matches your /{personalizedurl}/ it will route to Default/{action}.
What you want gets a bit tricky! I assume the personalizing is to be dynamic, not some static list of branded companies and you wouldn't want to recompile and deploy every time you add/remove a new one.
I think you will need to handle this in the controller, it won't work well in routing; unless it is a static list of personalized companies. You will need the ability to check if the first part is one of your actions and to check if it is a valid company, I will give you an example with simple string arrays. I believe you will be building the array by query some sort of data store for your personalized companies. I also have created a quick view model called PersonalizedViewModel that takes a string for the name.
Your routing will be simplified:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Admin",
url: "Admin/{action}/{id}",
defaults: new { controller = "Admin", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{url}/{action}",
defaults: new { controller = "Default", action = "Index", url = UrlParameter.Optional }
);
}
Here is the view model my example uses:
public class PersonalizedViewModel
{
public string Name { get; private set; }
public PersonalizedViewModel(string name)
{
Name = name;
}
}
And the Default controller:
public class DefaultController : Controller
{
private static readonly IEnumerable<string> personalizedSites = new[] { "companyA", "companyB" };
private static readonly IEnumerable<string> actions = new[] { "index", "plan", "investing", "etc" };
public ActionResult Index(string url)
{
string view;
PersonalizedViewModel viewModel;
if (string.IsNullOrWhiteSpace(url) || actions.Any(a => a.Equals(url, StringComparison.CurrentCultureIgnoreCase)))
{
view = url;
viewModel = new PersonalizedViewModel("Default");
}
else if (personalizedSites.Any(s => s.Equals(url, StringComparison.CurrentCultureIgnoreCase)))
{
view = "index";
viewModel = new PersonalizedViewModel(url);
}
else
{
return View("Error404");
}
return View(view, viewModel);
}
public ActionResult Plan(string url)
{
PersonalizedViewModel viewModel;
if (string.IsNullOrWhiteSpace(url))
{
viewModel = new PersonalizedViewModel("Default");
}
else if (personalizedSites.Any(s => s.Equals(url, StringComparison.CurrentCultureIgnoreCase)))
{
viewModel = new PersonalizedViewModel(url);
}
else
{
return View("Error404");
}
return View(viewModel);
}
}

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();
}
}

MVC URL re-writing

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.
