What is the equivalent of domain_get_domain()?

Question

I need the equivalent of domain_get_domain() in the Domain Access module for Drupal 8, but I can't find it.

I need to find the domain for the current request.

Answer 1

Finally worked out the following ...

$domainNegotiator = \Drupal::service('domain.negotiator');
$current = $domainNegotiator->negotiateActiveHostname();

There are other methods on the DomainNegotiator service that I thought should work, particularly getActiveDomain() and getActiveId(), but they didn't return the domain I was actually on like I thought they would.

It's still a bit confusing to me, but I made it work.

EDIT: @berramou 's answer below helped as well. Originally, I was looking for the Domain object (from the Domain Access module), but it turns out the host was enough to match a Domain reference on my entity.

Answer 2

In drupal 8 there is \Drupal::request() to get request info.

For Example if your url something like https://example.com

If you want only the domain name example.com

$domain = \Drupal::request()->getHost();

if you want the domain name with schema http or https https://example.com use this:

  $domain_with_schema = \Drupal::request()->getSchemeAndHttpHost();
