OutboundPathProcessorInterface::processOutbound $options['absolute'] does not work

The closest related issue I could find is this: https://www.drupal.org/project/drupal/issues/2873293 🐛 OutboundPathProcessorInterface does not correctly handle absolute urls anymore Closed: works as designed

Which was never resolved.

Path processors are for paths not urls

What are you trying to achieve?

What I wish to achieve:

Let's say I have a node, /node/210.

I have a table called "source urls". This table contains local paths I want re-directed to external sites. If a match is found, then I would like the user automatically sent to the external site.

So, when someone clicks on a link for this "/node/210" anywhere on my site, they are automatically redirected to the appropriate external site url.

The reason for this: I am building an AI response API that would allow users to embed and deploy a chatbot on their site for their content without them having to build and maintain this infrastructure themselves. So, ideally, /node/210 would consist of data from their site that we have processed for AI interaction, and rather than have the end-user access the data on our site, they are directed to the actual source.

You could build that with a link field from core and the field_redirection → module

Add a link field to the node-type that contains the source URL.

Configure manage display for the node-type and set the formatter for the link field to a redirect.

That would be a zero-code approach.

If you'd prefer a code approach, I think you want an event subscriber that listens to KernelEvents::RESPONSE

In the event subscriber you'd want something like this, this assumes you have a field called field_link_url on the node type, adapt as appropriate.

/**
   * Force the redirect to a link field.
   */
  public function redirectToLinkField(ResponseEvent $event) {
    $request = $event->getRequest();
    if ($request->get('_route') !== 'entity.node.canonical') {
      return;
    }

    $node = $request->get('node');
    $bundle = $node->bundle();

    if ($bundle == 'YOUR_NODE_TYPE') {
      if ($node->hasField('field_link_url') && !$node->field_link_url->isEmpty()) {
        $uri = $node->field_link_url->first()->getUrl()->setAbsolute(TRUE);
        $redirect = new TrustedRedirectResponse($uri->toString(), 301 /* pick what you want here */);
        $redirect->setMaxAge(2764800 /* here too */);
        $event->setResponse($redirect);
      }
    }
  }

@larowlan

Thank you VERY much for that guidance. Exactly what I needed.

Anyone else need to do something similar, this is how I utilized the Event Subscriber:

namespace Drupal\solrai\EventSubscriber;

use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\HttpKernel\Event\ResponseEvent;
use Drupal\Core\Routing\TrustedRedirectResponse;

class SolraiEventSubscriber implements EventSubscriberInterface {

  public static function getSubscribedEvents() {
    $events[KernelEvents::RESPONSE][] = ['redirectToExternalUrl', 0];
    return $events;
  }

  public function redirectToExternalUrl(ResponseEvent $event) {
    $request = $event->getRequest();
    if ($request->get('_route') !== 'entity.node.canonical') {
      return;
    }

    $node = $request->get('node');
    $nodePath = '/node/' . $node->id();

    $externalUrl = $this->lookupPathInTable($nodePath);

    if ($externalUrl) {
      $redirect = new TrustedRedirectResponse($externalUrl, 301);
      $redirect->setMaxAge(2764800);
      $event->setResponse($redirect);
    }
  }

  private function lookupPathInTable($path) {
    $pathMappings = [
		'/node/7849' => 'https://churchages.net/en/sermon/wesley/laying-the-foundation-of-the-new-chapel/',
		'/node/7850' => 'https://churchages.net/en/sermon/wesley/death-of-rev-mr-john-fletcher/'
      // Add more mappings as needed
    ];

    return $pathMappings[$path] ?? null;
  }
}
