Canonical url: current url vs full url

[ver4rs]

Hi.
I found this. On config file you have comment ...set null for URL::current() //is without query string

seotools/src/resources/config/seotools.php

Line 13 in 34794e6

'canonical' => false, // Set null for using Url::current(), set false to total remove

On Fasade class SEOMeta.class you have methon getCanonical() check link

seotools/src/SEOTools/SEOMeta.php

Line 535 in 34794e6

return $this->canonical ?: (($canonical_config === null) ? app('url')->full() : $canonical_config);

Inside this method you have when is null use app('url')->full(); // url full is with query string

\Laravel documentation URL: https://laravel.com/docs/5.8/urls
copied code

// Get the current URL without the query string...
echo url()->current();

// Get the current URL including the query string...
echo url()->full();

// Get the full URL for the previous request...
echo url()->previous();
