如何使用Symfony2访问该站点的完整基本URL

Question

I would like to get all of the base url of the site in my twig extension:

$this->service_container->get('request')->getBaseUrl()

gives me a lot but the host is missing...

another method maybe to get everything or one to get the host ?

Goal : have this :

http://my_host/request_base_url

Answer 1

$request = $this->getRequest();
$scheme = $request->getScheme();
$host = $request->getHttpHost();
$base = sprintf('%s://%s', $scheme, $host);
