I have a decent size MVC 4 app that is making heavy use of Areas, plus the basic Home and Account controller. What I need to do is have a URL pattern that goes to a Controller and passing the rest of the URL. I've tried just about every combination, but nothing seems to be working.
I created a controller called AutoInController with the following method:
[AllowAnonymous]
public ActionResult Index(string url)
{
string mes = string.Empty;
return View();
}
And I want to pass any URLs requested, starting with 'AutoIn' to this method with the rest of the url as the parameter. Here's the route I've tried, along with various others including using constraints. I'm adding this last, after the default.
routes.MapRoute(
"Autologin",
"AutoIn/{*url}",
new { controller = "AutoIn", action = "Index" }
);
Any ideas what I'm doing wrong. It shouldn't be this hard. Thanks.
I tried just about everything and the problem was that I couldn't get it to catch all that prefixed with 'AutoIn', just ALL.
I ended up changing my AccountController to handle this on the Login method to interrogate the URL and then if it was prefixed with 'AutoIn', take appropriate action.
Thanks for the answers. Routes can be tricky when you want to do some special stuff.

I am working on an ASP.NET MVC project. I need to be able to map a route such as this:
http://www.mysite.com/Products/Tennis-Shoes
Where the "Action" part of the URL (Tennis-Shoes") could be one of a list of possibilities. I do not want to have to create a separate Action method in my controller for each. I want to map them all to one Action method and I will handle the View that is displayed from there.
I have this working fine by adding a route mapping. However, there are some "Actions" that will need to have a hyphen in them. ASP.NET MVC routing is trying to parse that hyphen before I can send it to my action. I have tried to create my own custom Route Handler, but it's never even called. Once I had a hyphen, all routes are ignored, even my custom one.
Any suggestions? Details about the hyphen situation? Thanks you.
Looking at the URL and reading your description, Tennis-Shoes in your example doesn't sound like it should be an action, but a Route parameter. Let's say we have the following controller
public class ProductsController : Controller
{
public ActionResult Details(string product)
{
// do something interesting based on product...
return View(product);
}
}
The Details action is going to handle any URLs along the lines of
http://www.mysite.com/Products/{product}
using the following route
routes.MapRoute(
null,
"Products/{product}",
new
{
controller = "Products",
action = "Details"
});
You might decide to use a different View based on the product string, but this is just a basic example.
I have a rather archaic login system, and this is part of the login action:
// login action
return RedirectToAction("Action", new {
id = aVal,
name = aName,
// other params
});
It redirects the user to the Action action, and i noticed that name and the other params ended up being part of the final url scheme. I need to pass all those values to Action.
[HttpGet]
public ActionResult Action(int id, string name, ...) {
Is it possible to pass them to Action and having the url like this: /Controller/Action/123.
I need to restrict the Action method to only those who pass through the login action, the long url + query string make it almost impossible to make it through, but is there another more profesional way to do it.
Thanks and greetings to the SO and SE community.
In order to get Restful styled url's you need to setup an appropriate route.
So in your case something like
routes.MapRoute("MyRoute", "MyController/MyAction/{id}/{name}", new { controller = "MyController", action = "MyAction" });
you can see some other examples here
The second part of your question is more vague - you may want to tag your class with an [Authorize] attribute and then override OnAuthorization where you can do any checks. Not sure if this is what you are looking for.
There is an example of this here
I'm trying to put in some new routes but not sure where to start. What I would like to do is to have my routes translate as follows:
/transport class A/23 translated to /info/classes/A-23
I understand the basics of using MapRoute but can I do things like the above?
I hope someone can give advice.
This seems to me that you're actually after something like UrlRewrite since you're going from one Url to another.
But MVC doesn't rewrite Urls - it maps them to controller actions based on route patterns you provide.
So, if you're asking if you can split up the first url to a controller/action pair (with parameters) then of course you can. You just set up a route with the necessary parameters in the right place. So you could call MapRoute with something like (I would use hyphens for the spaces):
/*route pattern:*/ "transport-class-{class1}/{class2}"
/*with route defaults:*/ new { controller = "Info", action = "ViewInfo" }
Then you could write a controller as follows:
public class InfoController : ControllerBase
{
public ActionResult ViewInfo(string class1, string class2)
{
//presumably get model data from the class parameters here
//and pass it as parameter to below:
return View();
}
}
Although it would depend also if the transport and class constants in this route are actually also variable I guess - in which case you could push those down as route parameters, and into the parameter list of your controller method.
I am fairly new to asp.net and I have a starting URL of http://localhost:61431/WebSuds/Suds/Welcome and routing code
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{page}", // URL with parameters
new { controller = "Suds", action = "Welcome", page = 1 } // Parameter defaults
);
routes.MapRoute(
"Single",
"{controller}/{action}",
new { controller = "Suds", action = "Welcome" }
);
I am receiving the following error: 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.
Can anyone please help me figure out how to route the beginning url to the controller.
Because the first part of your URL is WebSuds, the framework is trying to map the request to WebSudsController instead of SudsController. One thing you can try is to change the url parameter of your route to "WebSuds/{controller}/{action}".
Route tables are searched on a first come first served basis. Once an appropriate match is found any following routes will be ignored.
You need to add "WebSuds/{controller}/{action}" and put it above the default route. The most specific routes should always go above the more generic ones.
With the following Routes and Url you have given make sure you have these Methods in your Controller
public class SudsController
{
public ActionResultWelcome(int? page)
{
return View();
}
}
Since you have created two routes of the same Action, one with a parameter page and another without. So I made the parameter int nullable. If you don't make your parameter in Welcome nullable it will return an error since Welcome is accepting an int and it will always look for a Url looks like this, /WebSuds/Suds/Welcome/1. You can also make your parameter as string to make your parameter nullable.
Then you should have this in your View Folder
Views
Suds
Welcome.aspx
If does doesn't exist, it will return a 404 error since you don't have a corresponding page in your Welcome ActionResult.
If all of this including what BritishDeveloper said. This should help you solve your problem.
I have an action method, and depending on what is passed to it, I want to redirect to another action in another controller. The action and controller names are determined at run time.
If I return RedirectToAction(), it will force a redirect and change the URL in the browser. What I would like is something like TransferToAction() that can transfer processing of the current request to another action, without doing a redirect. I seem to remember a method behaving like this in earlier previews, but I can't seem to find it in the RC of ASP.NET MVC.
Do you know how I would do this?
UPDATE
I added the following route:
routes.MapRoute(
"PageRouter",
"{site}/{*url}",
new { controller = "PageRouter",
action = "RoutePage", site = "", url = "" }
);
And the PageRouter controller action RoutePage:
public ActionResult RoutePage(string site, string url)
{
var controller = new HomeController {ControllerContext = ControllerContext};
controller.RouteData.Values["controller"] = "Home";
controller.RouteData.Values["action"] = "Index";
return controller.Index(site, url);
}
I had to set the controller and action in RouteData for the Home Index view to be rendered. Otherwise, it would look for an Index view in PageRouterController.
I still need to figure out how to create a controller and its action knowing only their names. e.g. I'd like to be able to just call something like this:
public ActionResult RoutePage(string site, string url)
{
return InvokeAction("Home", "Index");
}
What should go in InvokeAction() ? Do I need to pass it any context?
You should be able to just call the other method directly and, assuming that it returns a ViewResult, it will render that view in response to the request and the url will not change. Note, you'll be responsible for making sure that all of the data that the other method needs is available to it. For example if your other method requires some form parameters that weren't provided, you may need to construct a suitable FormCollection and set the ValueProvider of the controller to a ValueProvider based on your FormCollection. Likewise with any arguments required by the method.
