Question

我正在使用symfony 4.0和created a custom config file。我将此配置文件值设置为参数，以便我可以在控制器中获取它们。但我想将它们传递给twig。我怎么能这样做？可以直接在config.yml中分配应用程序配置，还是可以使用twig扩展名来实现？我找到了getGlobals()，但这已被弃用。仍然使用枝条功能，但似乎不是一个好方法。

最好，谢谢！

AppExtension.php：

namespace AppBundle\DependencyInjection;

use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
use Symfony\Component\Config\FileLocator;


class AppExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = $this->getConfiguration($configs, $container);
        $config = $this->processConfiguration($configuration, $configs);
        $container->setParameter('config', $config); 
    }

}

?>

资源/配置/ app.yml：

app:
  document_access:
    payment:
        bank_details:
          account_owner: xxx
          iban: Iban
          bic: Bic

ConfigExtension.php

namespace AppBundle\Twig;

use Symfony\Component\DependencyInjection\ContainerInterface;

class ConfigExtension extends \Twig_Extension
{

    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
    }

    public function getFunctions(){
        return array(
            new \Twig_SimpleFunction('config', array($this, 'getConfig')),
        );
    }

    public function getConfig()
    {
        return $this->container->getParameter('config');
    }
}

将所需的变量设置为环境变量和参数。

然后你可以将参数注入控制器或将变量注册为twig globals。

<强>控制器

class AngularController
{
    protected $twig;
    protected $accountOwner;
    protected $iban;
    protected $bic;

    /**
     * AngularController constructor.
     * @param $accountOwner
     * @param $iban
     * @param $bic
     */
    public function __construct(\Twig_Environment $twig, $accountOwner, $iban, $bic)
    {
        $this->twig=$twig;
        $this->accountOwner = $accountOwner;
        $this->iban = $iban;
        $this->bic = $bic;
    }


    /**
     * @Route("/uri", name="your_route")
     */
    public function yourActionAction()
    {
        $data=["account_owner"=>$this->accountOwner, "iban"=>$this->iban, "bic"=>$this->bic];
        $content=$this->twig->render('Bundle:Bundle:index.html.twig', $data);
        $response=new Response($content);
        return $response;
    }
}

controller.angular:
class: DJABundle\Controller\AngularController
arguments:
    - "@twig"
    - %bank_account_owner%
    - %bank_iban%
    - %bank_bic%

Twig globals

# app/config
twig:
    [...]
    globals:
        account_owner: %bank_account_owner%
        iban: %bank_iban%
        bic: "%bank_bic%"

控制器和全局变量的twig用法

Bank account owner: {{ account_owner }}
Bank account iban: {{ iban }}
Bank account bic: {{ bic }}

将配置值传递给twig
