在休息api中，我使用“/ rest / V1 / guest-carts / e3e1fd447e0e315dd761942cf949ce5d / items”方法来获取magento购物车项目。它运作良好，结果是
[
{
"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"
}
]
现在我想要获取列表中每个产品的图像（可能是缩略图）。有没有办法达到这个结果？
按照步骤在购物车中通过Rest API获取产品缩略图图像，无需POST任何值。它将采用产品的当前缩略图。休息网址：
