在检查输出之前，如果安装了正确的方法，则可以检查var/generation/Magento/Quote/Api/Data/CartItemExtension.php具有如下值:
Before checking your out put, If you installed the correct method you can check your var/generation/Magento/Quote/Api/Data/CartItemExtension.php has the value like this:
<?php
namespace Magento\Quote\Api\Data;
/**
* Extension class for @see \Magento\Quote\Api\Data\CartItemInterface
*/
class CartItemExtension extends \Magento\Framework\Api\AbstractSimpleObject implements \Magento\Quote\Api\Data\CartItemExtensionInterface
{
/**
* @return string|null
*/
public function getImageUrl()
{
return $this->_get('image_url');
}
/**
* @param string $imageUrl
* @return $this
*/
public function setImageUrl($imageUrl)
{
$this->setData('image_url', $imageUrl);
return $this;
}
}
