Some pages have an extra screen before the real site appears, e.g. for age verification (like porn, for now anyways, or drug sites) or country/currency selection (like travel and big company sites). As far as I researched this, sometimes the selection is stored in a cookie, sometimes in Web Storage.

Crawling with Cookies is no problem with Guzzle.

But for example, at https://cannabis.wiki the age verification is stored in the Local Storage as you can see in the Chrome DevTools:

Using spatie/crawler we can inject a Browsershot (puppeteer) instance, that sets the localStorage key ageConfirmed through custom JavaScript:

$js = "localStorage.setItem('ageConfirmed', '1');";
$browsershot->setOption('addScriptTag', json_encode(['content' => $js]));

However, the code is only injected after the side is already loaded. Therefore we have to use JavaScript to reload the page:

$js = "localStorage.setItem('ageConfirmed', '1');location.reload()";
$browsershot->setOption('addScriptTag', json_encode(['content' => $js]));

You can test this on the console e.g. by using ->save($pathToFile); and have a look at the screenshot to see if it worked.
