从控制台运行时的Symfony资产URL

Question

I want to add a asset (image) full url (with domain and base) in a twig template when running from a command line (Console Command). It's meant to be sent to email.

The problem is, using absolute_url(asset()) doesn't include the host and base path when running on console.

Also, as specificed in http://symfony.com/doc/current/console/request_context.html, it just works for urls, not for assets.

I've also tried to set the router context when running from console:

$context = $this->getContainer()->get('router')->getContext();
$context->setHost($defaultDomain);
$context->setScheme($scheme);

With no success. Any idea?

In my application, special for this situation with emails, i added global variable into Twig configuration:

# app/config/config.yml
twig:
    globals:
        site_addr: "%site_addr%"

And setting this variable in parameters.yml

# app/config/parameters.yml
site_addr: https://some.site

And at last, in each email template i used this:

# AppBundle/Resources/views/Emails/layout.html.twig
<img src="{{ site_addr ~ asset('SomeAssetName') }}"/>
