用于简单功能的twig is_safe不起作用

Question

我创建了一个简单的函数,用js渲染模板.我想它自动调用所以我已经将is_safe参数设置为array(html')而不必使用| raw filter

但它不起作用,jsis没有转义,而是呈现为纯文本.如果我使用原始过滤器,它可以正常工作.

我怎么解决这个问题？

我的简单功能:

<?php

namespace AppBundle\Extension\Twig;

use AppBundle\FoodMeUpParameters;
use AppBundle\Model\Interfaces\ViewCountInterface;
use ReflectionClass;
use Symfony\Component\DependencyInjection\ContainerInterface;

class FMUTwigExtension extends \Twig_Extension
{
    /**
     * @var ContainerInterface
     */
    private $container;

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

    public function getFunctions()
    {
        return array(
            'increaseViewCount' => new \Twig_SimpleFunction('increaseViewCount', array($this, 'increaseViewCount', array('is_safe' => array('html')))),
        );
    }


    public function increaseViewCount(ViewCountInterface $entity, $andFlush = true)
    {
        $reflect = new ReflectionClass($entity);

        $parameters = array(
            'short_name' => $reflect->getShortName(),
            'identifier' => $entity->getId(),
            'and_flush' => $andFlush
        );

        return $this->container->get('templating')->render(':Helper:increase_view_count.htmpl.twig', $parameters);
    }
}

我的模板:

<script>
    $(function(){
        $.ajax({
            url: '{{ path('increase_view_count') }}',
            type: "post",
            dataType: "json",
            data: {shortName: '{{ short_name }}', identifier: '{{ identifier }}', andFlush: '{{ and_flush }}'},
            success: function (result) {
                console.log(result);
            }
        });
    });
</script>

服务声明

fmu_twig_extension:
    class: %fmu_twig_extension.class%
    calls:
        - [setContainer, [@service_container]]
    tags:
        - { name: twig.extension }

Answer 1

您已将'is_safe'选项包含在回调中,而不是在next($options)参数中.

你需要改变....

'increaseViewCount' => new \Twig_SimpleFunction('increaseViewCount', array($this, 'increaseViewCount', array('is_safe' => array('html')))),

... 至 ...

'increaseViewCount' => new \Twig_SimpleFunction('increaseViewCount', array($this, 'increaseViewCount'), array('is_safe' => array('html'))),

Answer 2

我想，根据你的情况，你应该选择'is_safe' => ['js']. 如果由于某种原因它没有帮助，您可以使用 Twig 的过滤器中的定义raw，其中定义is_safe为all。
