动态容器参数

您可以设置容器参数在位于 Acme\BlogBu​​ndle\DependencyInjection\AcmeBlogExtension 的捆绑包扩展名中动态地进行设置，之后，您可以在路由中使用这些参数，例如％parameter ％。

Dynamic Container Parameters

You can set container parameters dynamically in your bundle's extension located Acme\BlogBundle\DependencyInjection\AcmeBlogExtension afterwards you can use those parameters in your routes like %parameter%.

namespace Acme\BlogBundle\DependencyInjection;

use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\ContainerBuilder;

class AcmeBlogExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $container->setParameter(
            'current_year',
            date("Y")
        );

        $container->setParameter(
            'current_month',
            date("m")
        );

        $container->setParameter(
            'current_day',
            date("d")
        );
    }
}

路由配置

Routing Configuration

blog:
    path:      /blog/{year}/{month}/{day}
    defaults:  { _controller: AcmeBlogBundle:Blog:index, year: %current_year%, month: %current_month%, day: %current_day% }

静态参数

如果只需要可配置的静态参数，则可以将其添加到 config.yml 中。

parameters:
    static_parameter: "whatever"

...然后在您的路由中再次访问它们，例如％static_parameter％。

... then again access them in your routing like %static_parameter%.
