Incorrect Uri::root() with external PHP file

Question

The file /srv/http/components/com_mycomponent/ajax/editAction.php was initialized with https://github.com/joomla/joomla-cms/issues/34586#issuecomment-865080001, except that we use

define('JPATH_BASE', __DIR__ . '/../../../');

The server root is at /srv/http. However, Uri::root() would return http://localhost/components/com_mycomponent/ajax/.

How do I make it return http://localhost/?

Answer 1

In core applications the root URI is manually set by passing the root path as second parameter to Uri::root() method.

use Joomla\CMS\Uri\Uri;

Uri::root(false, rtrim(\dirname(Uri::base(true), 3), '/\\'));
