尝试使用twig功能时Twig环境未注入shopware 6.5.4.0如何解决

Question

我正在开发一个自定义插件，它接受来自 api 的数据。

我正在尝试使用 twig 函数来获取如下数据

twig功能类：

<?php declare(strict_types=1);

namespace Nst\Twig;

use Nst\Service\StoryblokService;
use Twig\Extension\AbstractExtension;
use Twig\TwigFunction;

class StoryblokTwigExtension extends AbstractExtension
{
    public function __construct(private StoryblokService $storyblokService)
    {
  
    }

    public function getFunctions(): array
    {
        return [
            new TwigFunction('get_story', [$this, 'getStory']),
        ];
    }

    public function getStory(string $slug): array
    {
        return $this->storyblokService->getStory($slug);
    }
}

也在我的服务中：

<?xml version="1.0" ?>

<container xmlns="http://symfony.com/schema/dic/services">
    <services>
        <service id="Nst\Service\StoryblokService" public="true">
            <argument type="service" id="Storyblok\Client"/>
        </service>
        
        <service id="Storyblok\Client" class="Storyblok\Client">
            <argument>%env(dumpcode)%</argument>
        </service>

        <service id="Nst\Storefront\Controller\CodesController" public="true">
            <argument type="service" id="twig"/>
            <call method="setContainer">
                <argument type="service" id="service_container"/>
            </call>
        </service>
    </services>
</container>

然后在我渲染页面的控制器中，我尝试注入到我的构造中以供使用。

<?php declare(strict_types=1);

namespace Nst\Storefront\Controller;

use Shopware\Storefront\Controller\StorefrontController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Twig\Environment;

/**
 * @Route(defaults={"_routeScope"={"storefront"}})
 */
class CodesController extends StorefrontController
{    


    public function __construct(Environment $twig)
    {
        $this->twig = $twig;
    }
    
    public function setTwig(Environment $twig): void
{
    $this->twig = $twig;
    error_log('Twig has been set.'); // or use your preferred logging method
}

    /**
    * @Route("/mystore", name="frontend.example.example", methods={"GET"}, defaults={"_routeScope"={"storefront"}})
    */
    public function showPage(): Response
    {
        if (!$this->twig) {
            error_log('Twig is not set.');
        }
        
        return $this->renderStorefront('@Nst/storefront/page/example.html.twig', [
            'example' => 'Hello world'
        ]);
    }
}

我的 twig 页面的副本，我需要这个 twig 函数来显示从 api 消耗的数据。

{% sw_extends '@Storefront/storefront/base.html.twig' %}

{% block base_content %}
    <h1>Our example controller!</h1>
{% endblock %}

{% set story = get_story('ola-landing-page') %}

{% if story %}
    {# Display your story content here #}
    {{ story.content.title }}
    {# Add more fields as required from the story #}
{% endif %}

但我不断

hp.CRITICAL: Uncaught Error: Too few arguments to function Nst\Storefront\Controller\CodesController::__construct(), 0 passed in 

Uncaught PHP Exception Shopware\Storefront\Controller\Exception\StorefrontException: "Class Nst\Storefront\Controller\CodesController does not have twig injected. Add to your service definition a method call to setTwig with the twig instance" at 

我不知道该怎么办，已经坚持了很长时间，请帮忙

您可以通过添加needs_environment选项并将其设置为true来自动注入twig环境，然后正确的实例将自动传递给您的TwigFunction

<?php declare(strict_types=1);

namespace Nst\Twig;

use Nst\Service\StoryblokService;
use Twig\Extension\AbstractExtension;
use Twig\TwigFunction;

class StoryblokTwigExtension extends AbstractExtension
{
    public function __construct(private StoryblokService $storyblokService)
    {
  
    }

    public function getFunctions(): array
    {
        return [
            new TwigFunction('get_story', [$this, 'getStory'], [ 'needs_environment' => true),
        ];
    }

    public function getStory(\Twig\Environment $twig, string $slug): array
    {
        /*
            Now you can use $twig to render something
            or you could even pass it to the service if needed/wanted
            ....
            return $twig->render(....);
            $this->storyblockService->setTwig($twig);
            ...
        */   
        return $this->storyblokService->getStory($slug);
    }
}
