Question

嗨，我如何在后端检索类别URL的值？我期望url值等于前端中的url，而不是后端中的url。在Magento 2中有没有办法实现这一目标？

好的，我找到了答案。解决方案是使用Magento中提供的App / Emulator。这个想法是在执行所需的前端类别URL检索之前开始仿真，并在完成后关闭仿真。

以下是有关如何实现它的链接App Emulation。不知道解决这个问题很简单。下面是我的代码的样子

class MenuCategory extends \Magento\Framework\Model\AbstractModel implements \Magento\Framework\DataObject\IdentityInterface
{

    public function getStoreCategories($storeManager, $emulator)
    {

        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
        $emulator->startEnvironmentEmulation(null, \Magento\Framework\App\Area::AREA_FRONTEND, true);

        $categoryFactory = $objectManager->create('Magento\Catalog\Model\ResourceModel\Category\CollectionFactory');
        $categories = $categoryFactory->create()                              
            ->addAttributeToSelect('*')
            ->setStore($storeManager->getStore())
            ->addAttributeToFilter('level', array('eq' => 2))
            ->addIsActiveFilter()
            ->addAttributeToSort('position', 'asc'); 

        foreach ($categories as $category) {    
            echo $category->getUrl() . " - " . $category->getUrl() . "\n";

        }

        $emulator->stopEnvironmentEmulation();
        return $content;
    }
}

因此，这里的想法是实例化模拟器，并使magento认为您将像在前端一样进行修改或执行，因此代码 \ Magento \ Framework \ App \ Area :: AREA_FRONTEND 当您关闭环境仿真时，它将回到原来的状态，无论您使用的是adminhtml还是前端

要获取类别网址，您需要像这样使用Magento\Catalog\Model\CategoryRepository函数getUrl()：

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$emulator->startEnvironmentEmulation(null, \Magento\Framework\App\Area::AREA_FRONTEND, true);

$categoryFactory = $objectManager->create('Magento\Catalog\Model\ResourceModel\Category\CollectionFactory');
$categories = $categoryFactory->create()                              
    ->addAttributeToSelect('*')
    ->setStore($storeManager->getStore())
    ->addAttributeToFilter('level', array('eq' => 2))
    ->addIsActiveFilter()
    ->addAttributeToSort('position', 'asc'); 

foreach ($categories as $category) {    
    $categoryObject = $objectManager->create('Magento\Catalog\Model\CategoryRepository')->get($category->getId());
    echo $categoryObject->getUrl()."\n";
}

在后端Magento中显示前端类别URL
