Shopify购买按钮的最大数量

问题描述

使用Shopify购买按钮向网络应用的用户发布免费产品。需要确保用户最多只能订购1件商品。关于如何执行此操作的任何想法？

Shopify扩展程序是不行的，因为购买按钮不会加载它们。还对结帐链接进行了实验，这些链接将无法防止出现双重订单。

以下是“购买”按钮的代码：

<script type="text/javascript">
/*<![CDATA[*/
(function () {
  var scriptURL = 'https://sdks.shopifycdn.com/buy-button/latest/buy-button-storefront.min.js';
  if (window.ShopifyBuy) {
    if (window.ShopifyBuy.UI) {
      ShopifyBuyInit();
    } else {
      loadScript();
    }
  } else {
    loadScript();
  }
  function loadScript() {
    var script = document.createElement('script');
    script.async = true;
    script.src = scriptURL;
    (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(script);
    script.onload = ShopifyBuyInit;
  }
  function ShopifyBuyInit() {
    var client = ShopifyBuy.buildClient({
      domain: 'heavysoundlabs.myshopify.com',storefrontAccessToken: '28703a091818546612d47f7c83047f6f',});
    ShopifyBuy.UI.onReady(client).then(function (ui) {
      ui.createComponent('product',{
