Getting protocol from the URL in controller

Question

I Googled it but maybe my search keywords are useless so how can I get URL protocol in controller? IS it http:// or https://

http://whatever.com/app_dev.php/welcome

//I need to echo http:// protocol here
echo $request->getHost(); //echos whatever.com
echo $request->getBaseUrl(); //echos app_dev.php/

Answer 1

You can use this in your controller :

$scheme = $this->getRequest()->getScheme();

Otherwise, here is a code allowing you to know all the values ​​returned by the server:

 foreach ($_SERVER as $key => $value) {
      echo $key.' => '.$value.'<br>';
    }

Answer 2

To check if request is https use:

$request->isSecure()
