How can i get full url to include in newsletter sent with Symfony2?

Question

I'm going to use Symfony2 to sent periodically a newsletter to many users. I've to include a permalink to the HTML email for those who experience problems in reading them with an email client.

Anyway, assuming that i'm sending the newsletter this way:

// Assume success and create a new SentMessage to store and get permalink
$sent = new SentMessage();

$sent->setRecipients(/* ... */);
$sent->setSubject(/* ... */);
$sent->setContent(/* ... */);

// Get the slug for the new sent message
$slug = $sent->getSlug(); // Like latest-product-offers-546343

// Construct the full URL
// e.g. http://mydomain.com/newsletter/view/latest-product-offers-546343

// Actually send a new email
$mailer->send(/* .. */);

How can i construct the full URL (domain + controller + action + slug) to include it in a new email?

With the router, of course

By default, the router will generate relative URLs (e.g. /blog). To generate an absolute URL, simply pass true to the third argument of the generate() method:

Perhaps your code might look like this

Symfony2

$url = $router->generate(
    'slug_route_name',
    array('slug' => $sent->getSlug()),
    true // This guy right here
);

Symfony3

use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

$url = $router->generate(
    'slug_route_name',
    array('slug' => $sent->getSlug()),
    UrlGeneratorInterface::ABSOLUTE_URL // This guy right here
);
