You can generate the url from the request object:

<pre><code>$baseurl = $request-&gt;getScheme() . '://' . $request-&gt;getHttpHost() . $request-&gt;getBasePath();
</code></pre>

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

see <code>Symfony\Component\Routing\Generator\UrlGenerator::doGenerate</code> for a more solid implementation.

Also, Twig has access to the request from <code>app.request</code>.

You can use the <code>templating.helper.assets</code> service.

First define your <a href="http://symfony.com/doc/current/reference/configuration/framework.html#assets-base-urls" rel="noreferrer">assets base URL</a> :

<pre><code># app/config/config.yml
framework:
 templating:
 assets_base_url: "http://www.mywebsite.com/"
</code></pre>

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

<pre><code>&lt;?php

// src/Acme/Bundle/DemoBundle/Controller/DemoController.php

namespace Acme\Bundle\DemoBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class DemoController extends Controller
{
 public function indexAction()
 {
 $myAssetUrl = $this
 -&gt;get('templating.helper.assets')
 -&gt;getUrl('bundles/acmedemo/js/main.js', $packageName = null)
 ;

 // $myAssetUrl is "http://www.mywebsite.com/bundles/acmedemo/js/main.js"

 return array();
 }
}
</code></pre>

Method <code>app.request.uriForPath()</code> gives an absolute URL from a path. Helper <code>asset()</code> gives the path of an asset.

<pre><code>{{ app.request.uriForPath(asset('bundles/mybundle/images/name.png')) }}

It's important to have both for the case where the application is not at the root of the domain, for eg:

The best solution would be IMHO to look at <code>Twig</code>'s implementation of <code>asset</code>, which you can find in:

<pre><code>\Symfony\Bundle\TwigBundle\Extension\AssetsExtension
</code></pre>

in the method:

<pre><code>public function getAssetUrl($path, $packageName = null, $absolute = false, $version = null)
</code></pre>

which basically uses the <code>templating.helper.assets</code> service similar to @iamdto's answer:

<pre><code>$url = $this-&gt;container-&gt;get('templating.helper.assets')-&gt;getUrl($path, $packageName, $version);
</code></pre>

Or directly use the <code>AssetsExtension</code> service or class respectively.

Working solution in Symfony 3.3+

<pre><code># app/config/config.yml
parameters:
 ...
 base_url: 'http://mywebsite.com'
</code></pre>

To get it in your controller action:

<pre><code>$baseUrl = $this-&gt;getParameter('base_url');
</code></pre>

You can now append your image to it e-g: <code>$baseUrl . '/uploads/' . $image</code> or if you like you can define uploaded assets base url in config.yml and access it in controller action.

Best thing about this solution would be the ability to pre-define it for different environments e-g: in <code>config.yml</code>, <code>config_dev.yml</code> and <code>config_test.yml</code> so when you move your project between different environments, you don't have to change it as it's already there..

For CDNs, you can also inject the <code>Packages</code> directly into your service.

First the asset base url in config.yml:

<pre><code>framework:
 assets:
 base_url:
 - 'http://cdn.mysite.com'
</code></pre>

Then the fun part:

<pre><code>namespace App\Service;

use Symfony\Component\Asset\Packages;

class SomeClass
{
 private $packages;

 public function __construct(Packages $packages)
 {
 $this-&gt;packages = $packages;
 }

 public function proxyToAssetUrl(string $path): string
 {
 return $this-&gt;packages-&gt;getUrl($path);
 }
}
</code></pre>

If you have autowiring enabled then you won't need to configure anything in your <code>services.yml</code>, otherwise something like:

<pre><code>services:
 App\Service\SomeClass:
 class: App\Service\SomeClass
 arguments: ['@assets.packages']
</code></pre>
