如何从symfony 2控制台访问twig中的基本URL？

Question

I am porting my website which is in Kohana to Symfony 2 gradually. Right now I am writing backend command in Symfony2, eg cron to send email notifications.

How can I access base url in twig. Can I do some configuration so that accessing urls in twig from console and from http request to be same ?

I have already reffered to this,

http://symfony.com/doc/current/cookbook/console/sending_emails.html

http://symfony.com/doc/current/cookbook/templating/global_variables.html

here, it is given how to configure it, but it is not mentioned how to access it, I assume I have to use {{ router.request_context.host }}.

But my question is, isn't there any way to be consistent between console and HTTP ?

eg {{ url }} ?

Answer 1

Add following setting in parameters.yml,

router.request_context.scheme: http
router.request_context.host: domain.com
base_url: '%router.request_context.scheme%://%router.request_context.host%/'

and inside console command controller you can access like,

$host =  $this->getContainer()->get('router')->getContext()->getHost();
$scheme =  $this->getContainer()->get('router')->getContext()->getScheme();
$baseURL = $this->getContainer()->getParameter('base_url');

First, you must set the url (you're calling it base_url) in a route by adding the following lines to /app/config/routing.yml:

base_url:
    pattern:  /

After that, you must set the router.request_context parameters as mentioned in the Symfony cookbook.

Now that everything's setup, you can simply use the same url functions in Twig as you would do in your webpages:

{{ url('base_url') }}

This worked for me.

In config.yml:

twig:
   globals:
       base_url: "http://www.example.com/"

In twig template:

{{ base_url }}
