Symfony2: how to set the host/base url in CLI scripts

问题

I'm currently writing a newsletter tool, and therefore have to generate absolute URLs in a CLI script which is called via cron.

Unfortunately the Symfony CLI command does not know anything about my host/base_url, so the router generates absolute URLs with a wrong base_url. It always uses http://localhost as base.

Is there a way to tell the router the correct base_url?

My code:

$this->container->get('router')->generate($route, $parameters, true);

回答1:

You can do it in this way:

$host = $this->getContainer()->getParameter('host');
$this->getContainer()->get('router')->getContext()->setHost($host);

Similarly you can set baseurl and scheme:

$this->getContainer()->get('router')->getContext()->setScheme('https');
$this->getContainer()->get('router')->getContext()->setBaseUrl('/web');

Since 2.1 you can configure the default parameters of the router, which is probably the best approach. A CLI script will use these default parameters, however a web request will override them:

# app/config/parameters.yml
parameters:
    router.request_context.host: example.org
    router.request_context.scheme: https
    router.request_context.base_url: my/path

$host = $this->container->getParameter('host'); $this->container->get('router')->getContext()->setHost($host);
