ios - 从 magento 2.0 REST Api 获取多个产品图像以用于购物车列表 - Swift 4
<p><p>我们正在使用 <strong>Magento 2.0</strong>。我在购物车列表页面中苦苦挣扎以显示产品图片。 </p>
<p>有了这个:</p>
<p><code>V1/carts/mine/items</code>(购物车列表 api)我无法获取产品图片。 </p>
<p>所以我使用 <code>V1/products/(sku)/media</code> api 来获取产品图像，通过在产品 sku/s 的 for 循环中调用它来在列表中显示它从购物车列表 api 中获得。 </p>
<p>我认为这不公平。因为如果我在购物车中有 10 个产品，那么我需要调用 <code>V1/products/(sku)/media</code> api 10 次，这会使我的应用程序变慢，也让我的用户厌倦了等待。当然，我可以异步加载产品图像，但即使是 10 个产品图像 api 调用 + 1 个购物车列表 api + 1 个购物车总计 api (<code>carts/mine/totals</code>) = 每个列表 12 个 api。如果发生任何编辑或删除，这应该再次发生。</p>
<p>建议一种更好的方法，或者是否有任何 url 或过滤选项可以在一个 api 中获取所有购物车产品图像？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我特此粘贴此问题的模块。</p>
<p>为rest api创建一个模块</p>
<p>按照步骤通过 Rest API 获取购物车中的产品缩略图，无需 POST 任何值。它将采用产品的当前缩略图图像。休息网址:</p>
