HTMLPurifier iframe Vimeo 和 Youtube 视频

How can I use HTMLPurifier to filter xss but also to allow iframe Vimeo and Youtube video?

require_once 'htmlpurifier/library/HTMLPurifier.auto.php';
$config = HTMLPurifier_Config::createDefault();
$config->set('HTML.Trusted', true);

$config->set('Filter.YouTube', true);
$config->set('HTML.DefinitionID', '1');
$config->set('HTML.SafeObject', 'true');
$config->set('Output.FlashCompat', 'true');

$config->set('HTML.FlashAllowFullScreen', 'true');

$purifier = new HTMLPurifier($config);
$temp = $purifier->purify($temp);

推荐答案

HTMLPurifier 4.4.0 版具有允许 YouTube 和 Vimeo iframe 的新配置指令:

//allow iframes from trusted sources
$cfg->set('HTML.SafeIframe', true);
$cfg->set('URI.SafeIframeRegexp', '%^(https?:)?//(www.youtube(?:-nocookie)?.com/embed/|player.vimeo.com/video/)%'); //allow YouTube and Vimeo
