我的问题是Stripe的元数据对象有500个字符的限制。我有一个工作结帐流程，但我唯一的限制是我的购物车的字符限制。我的cartItems对象有额外的和客户注解，我想包括每个购物车项目。与此同时，元数据限制得到500个字符快。我读了另一个职位here，在我的应用程序中实现了websockets，这样我就可以在监听到stripes事件后使用它来创建订单。我该怎么做呢？还有其他的解决方法吗？

let endpointSecret;
endpointSecret =
  "whsec_bd73383ed0fcf9cfb27bd4929af341605ad32577dfd8825e1143425b846bb3c3";

router.post("/webhook", (request, response) => {
  const sig = request.headers["stripe-signature"];

  let data;
  let eventType;

  if (endpointSecret) {
    let event;

    try {
      event = stripe.webhooks.constructEvent(
        request.rawBody,
        sig,
        endpointSecret
      ); //@JA - Had to modify this to take the rawBody since this is what was needed.
    } catch (err) {
      response.status(400).send(`Webhook Error: ${err.message}`);
      return;
    }

    data = event.data.object;
    eventType = event.type;
  } else {
    data = request.body.data.object;
    eventType = request.body.type;
  }

  // Handle the event
  if (eventType === "checkout.session.completed") {
    stripe.customers
      .retrieve(data.customer)
      .then((customer) => {
        console.log("customer:", customer);
        console.log("data:", data);
        createOrder(customer, data);
      })
      .catch((err) => console.log(err.message));
  }
