OR

Answer 1

$protocol = stripos($_SERVER['SERVER_PROTOCOL'],'https') === true ? 'https://' : 'http://';

$hostName = $request->server->get('HTTP_HOST');
$baseDirectory = "";
if(!empty($this->container->get('router')->getContext()->getBaseUrl())){
    $baseDirectory = str_replace('app_dev.php', '', $this->container->get('router')->getContext()->getBaseUrl());
}
$rootUrl = $protocol.$hostName.$baseDirectory; 

Answer 2

嗯......检查一下：

$base = $this->getRequest()->getSchemeAndHttpHost();

或在最旧的版本中（我不记得何时更改）：

$request = $this->getRequest();
$scheme = $request->getScheme();
$host = $request->getHttpHost();

$base = sprintf('%s://%s', $scheme, $host);
