How to get node url in context of ContentService?

Using Umbraco And Getting Started

Umbraco 8

Hi,

I have this code:

using System;
using Umbraco.Core;
using Umbraco.Core.Composing;
using Umbraco.Core.Services.Implement;

namespace Umbraco8.Components
{
    [RuntimeLevel(MinLevel = RuntimeLevel.Run)]
    public class SubscribeToPublishEventComposer : ComponentComposer<SubscribeToPublishEventComponent>
    { }

    public class SubscribeToPublishEventComponent : IComponent
    {
        public void Initialize()
        {
            ContentService.Publishing += ContentService_Publishing;
        }

        private void ContentService_Publishing(Umbraco.Core.Services.IContentService sender, Umbraco.Core.Events.ContentPublishingEventArgs e, RequestContext requestContext, UmbracoContext umbracoContext)
        {
            // From https://our.umbraco.com/documentation/reference/events/ContentService-Events
            foreach (var node in e.PublishedEntities)
            {
                if (
                    node.ContentType.Alias == "siteNewsPage" || 
                    node.ContentType.Alias == "siteEvent"
                )
                {
                    string[] dateArray = node.GetValue<string>("date").Split('/');
                    node.SetValue("umbracoUrlAlias", dateArray[2].Substring(0, 4) + "/" + dateArray[1] + "/" + dateArray[0] + "/" + node.Url);
                }
            }
        }
        public void Terminate()
        {
            //unsubscribe during shutdown
             ContentService.Publishing -= ContentService_Publishing;
        }
    }
}

In this line I have an error ("node.Url" is not valid):

node.SetValue("umbracoUrlAlias", dateArray[2].Substring(0, 4) + "/" + dateArray[1] + "/" + dateArray[0] + "/" + node.Url);

How can I get the url of the node in this context? (I want to use only the last segment of the url, but that I can manage)

Hi Martin.

If you need the whole URL I would suggest you listening to the CacheRefresher event instead of the ContentService events, as the IContent won't have the URL, only the UrlSegment for itself.

UrlSegment would be: Node name: "About us" Url Segment: "about-us"

But to me it seems more like you are trying to create a new URL for the content, is that right?

Yes, I want to create a new url for news and event items. Take a event with this url: domain.com/events/my-event with date = 2021-02-16

I want umbracoUrlAlias to be "/events/2021-02-16/my-event". So I want to take the url (events/my-event) and split it by "/" so I get two segments ( (first, "events", and last, "my-event") and then put date in between.

So what I need help for is to get the url ("events/my-event" - or "/events/my-event/")

I can see that you asked another question and one of the answers was to create a custom URL provider and content finder, I think that is the road you should be going.

As far as I am concerned the IContent won’t contain the full URL, as it doesn’t know its ancestors per se, only the path and parent Id.

You could though get the ancestors in the Content Service and then concatenate their URL segments to make an URL.

Hi Martin, You may be able to achieve that with the URL Provider https://our.umbraco.com/documentation/reference/routing/request-pipeline/outbound-pipeline

About the code you posted I think you can have access to the umbraco helper and get the URL from there. https://our.umbraco.com/forum/umbraco-8/96270-using-umbracohelper-in-a-custom-class-in-v8#comment-304421

Oh btw try the published event, maybe the URL is null because it doesn't exist yet or you generate the URL based on the parent node and the name of the node you are saving

Thank you both. :) I tried looking into custom URL provider as suggested by Malthe. It is the most right way to do it - I knew, but thought it was very difficult. It wasn´t.

I got it working with this (App_Code\dateRouting.cs):

using Umbraco.Core.Models;
using Umbraco.Core.Strings;

namespace Umbraco8.Routing
{
    public class DatePageUrlSegmentProvider : IUrlSegmentProvider
    {

            readonly IUrlSegmentProvider _provider = new DefaultUrlSegmentProvider();

            public string GetUrlSegment(IContentBase content, string culture = null)
            {

                if (!(content.ContentType.Alias == "siteEvent" || content.ContentType.Alias == "siteNewsPage")) return null;

                var segment = _provider.GetUrlSegment(content);
                string[] dateArray = content.GetValue<string>("date").Split('/');

                return string.Format("{1}-{0}", segment, dateArray[2].Substring(0, 4) + "-" + dateArray[1] + "-" + dateArray[0]);
            }
    }
}

And the registrating it (App_Code\registrateComposers.cs):

using Umbraco.Core;
using Umbraco.Core.Composing;
using Umbraco8.Routing;

namespace Umbraco8.Composers
{
    public class RegisterCustomSegmentProviderComposer : IUserComposer
    {
        public void Compose(Composition composition)
        {
            composition.UrlSegmentProviders().Insert<DatePageUrlSegmentProvider>();
        }
    }
}
