magento 2 rest api：獲取帶有圖像的購物車項目

Question

在其他api中，我使用「/ rest/V1/guest-carts/e3e1fd447e0e315dd761942cf949ce5d/items」方法獲取magento購物車物品。它效果很好，結果是

[ 
{ 
    "item_id": 100, 
    "sku": "abc-1", 
    "qty": 1, 
    "name": "Product one", 
    "price": 19, 
    "product_type": "simple", 
    "quote_id": "e3e1fd447e0e315dd761942cf949ce5d" 
}, 
{ 
    "item_id": 101, 
    "sku": "abc-2", 
    "qty": 1, 
    "name": "Product two", 
    "price": 54, 
    "product_type": "simple", 
    "quote_id": "e3e1fd447e0e315dd761942cf949ce5d" 
} 
] 

現在我想獲得列表中每個產品的圖像（可能是縮略圖圖像）。有什麼辦法可以達到這個結果嗎？

       } 
      } 
     } 
}

按照步驟通過Rest API獲取產品縮略圖圖像在沒有POST任何值的Rest API中。它將採用當前產品的縮略圖圖像。 REST URL：

方法：GET - >休息/ V1 /客推車/ 3f260b6e818d2fe56894ed6222e433f8 /項目

之前檢查你出來說，如果你安裝你可以檢查你的VAR /生成/ Magento的/報價/原料藥/數據/ CartItemExtension.php具有這樣的價值的正確方法：

<?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; 
    } 
}
