Custom Routing
Learn everything you need to know about custom routing in Umbraco CMS.
There are a couple of ways of controlling the routing behavior in Umbraco: customizing how the inbound request pipeline finds content & creating custom MVC routes that integrate within the Umbraco pipeline.
Below lists the ways in which you can customize the inbound request pipeline, this is done by using native Umbraco plugin classes, notifications, or defining your own routes.
All Umbraco content is looked up based on the URL in the current request using an
IContentFinder
. IContentFinder's you can create and implement on your own which will allow you to map any URL to a Umbraco content item.A
IContentLastChanceFinder
is a special implementation of an IContentFinder
for use with handling 404's. You can implement one of these plugins to decide which Umbraco content page you would like to show when the URL hasn't matched a Umbraco content node.When creating packages or using class libraries, the
SetContentLastChanceFinder
is a part of the Umbraco.Cms.Web.Website
NuGet package.To set your own 404 finder create a
IContentLastChanceFinder
and set it as the ContentLastChanceFinder
. A ContentLastChanceFinder
will always return a 404 status code. Example:using Umbraco.Cms.Core.Composing;
using Umbraco.Cms.Core.DependencyInjection;
using Umbraco.Extensions;
namespace My.Website
{
public class UpdateContentFindersComposer : IComposer
{
public void Compose(IUmbracoBuilder builder)
{
//set the last chance content finder
builder.SetContentLastChanceFinder<My404ContentFinder>();
}
}
}
You can specify your own custom MVC routes to work within the Umbraco pipeline. It requires your controller to inherit from
UmbracoPageController
and either implement IVirtualPageController
or use .ForUmbracoPage
when registering your route, for more information and a complete example of both approaches see Custom routing documentationAn example of registering a
UmbracoPageController
using .ForUmbracoPage
:using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Mvc.Filters;
using Microsoft.Extensions.DependencyInjection;
using Umbraco.Cms.Core.Composing;
using Umbraco.Cms.Core.DependencyInjection;
using Umbraco.Cms.Core.Models.PublishedContent;
using Umbraco.Cms.Core.Web;
using Umbraco.Cms.Web.Common.ApplicationBuilder;
using Umbraco.Extensions;
namespace CustomRoutes
{
public class MyCustomRouteComposer : IComposer
{
public void Compose(IUmbracoBuilder builder)
{
builder.Services.Configure<UmbracoPipelineOptions>(options =>
{
options.AddFilter(new UmbracoPipelineFilter(nameof(MyController))
{
Endpoints = app => app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
"My custom controller",
"/custom/{action}",
new {Controller = "My", Action = "Index"})
.ForUmbracoPage(FindContent);
})
});
});
}
private IPublishedContent FindContent(ActionExecutingContext actionExecutingContext)
{
var umbracoContextAccessor = actionExecutingContext.HttpContext.RequestServices
.GetRequiredService<IUmbracoContextAccessor>();
var umbracoContext = umbracoContextAccessor.GetRequiredUmbracoContext();
return umbracoContext.Content.GetById(1064);
}
}
}
This is an approach for mapping a custom route to a custom MVC controller. For creating routes for existing content pages you can use a custom MVC controller to handle the request by naming convention: see Custom Controllers - Route Hijacking.
You can subscribe to the
RoutingRequestNotification
which is published right after the point when the PublishedRequestBuilder
is prepared - (but before it is ready to be processed). Here you can modify anything in the request before it is processed, eg. content, template, etc:using Umbraco.Cms.Core.Events;
using Umbraco.Cms.Core.Notifications;
namespace CustomRoutes
{
public class PublishedRequestHandler : INotificationHandler<RoutingRequestNotification>
{
public void Handle(RoutingRequestNotification notification)
{
var requestBuilder = notification.RequestBuilder;
// Do something with the IPublishedRequestBuilder here
}
}
}
For more information on how to register and use notification handlers see Notifications documentation
