How to get the full url for an asset in Controller?

You can generate the url from the request object:

$baseurl = $request->getScheme() . '://' . $request->getHttpHost() . $request->getBasePath();

You could make a twig extension that cuts the /web part of your path and uses the request to generate the base url.

see Symfony\Component\Routing\Generator\UrlGenerator::doGenerate for a more solid implementation.

Also, Twig has access to the request from app.request.

You can use this in Controller:

$this->getRequest()->getUriForPath('/uploads/myimage.jpg');

EDIT : This method also includes the app.php and app_dev.php to the url. Meaning this will only work in production when url-rewriting is enabled!

You can use the templating.helper.assets service.

First define your assets base URL :

# app/config/config.ymlframework:    templating:        assets_base_url: "http://www.mywebsite.com/"

Then just call the service from within your controller, command or wherever you are :

<?php// src/Acme/Bundle/DemoBundle/Controller/DemoController.phpnamespace Acme\Bundle\DemoBundle\Controller;use Symfony\Bundle\FrameworkBundle\Controller\Controller;class DemoController extends Controller{    public function indexAction()    {        $myAssetUrl = $this            ->get('templating.helper.assets')            ->getUrl('bundles/acmedemo/js/main.js', $packageName = null)        ;        // $myAssetUrl is "http://www.mywebsite.com/bundles/acmedemo/js/main.js"        return array();    }}
