已传入CustomerId但Stripe付款仍显示未知客户问题求助

核心问题：你在后端创建PaymentIntent时，没有将其与对应的Stripe Customer ID关联，导致Stripe无法识别该付款所属的客户，默认标记为访客。

查看你的后端代码，无论是新创建客户还是使用已有客户的分支，stripe.paymentIntents.create方法都只传入了amount和currency参数，缺少关键的customer字段。

修改后的后端代码 #

const user = await strapi.entityService.findOne(
  "plugin::users-permissions.user",
  ctx.state.user.id
);

if (user.stripeCustomerId == null) {
  const customer = await stripe.customers.create({ email: user.email });
  const result = await strapi.entityService.update(
    "plugin::users-permissions.user",
    ctx.state.user.id,
    {
      data: {
        stripeCustomerId: customer.id,
      },
    }
  );

  const ephemeralKey = await stripe.ephemeralKeys.create(
    { customer: customer.id },
    { apiVersion: "2024-06-20" }
  );

  // 新增customer字段关联到PaymentIntent
  const paymentIntent = await stripe.paymentIntents.create({
    amount: 4444,
    currency: "usd",
    customer: customer.id
  });

  return {
    ephemeralKey: ephemeralKey.secret,
    paymentIntent: paymentIntent.client_secret,
    customerId: customer.id,
  };
} else {
  const ephemeralKey = await stripe.ephemeralKeys.create(
    { customer: user.stripeCustomerId },
    { apiVersion: "2024-06-20" }
  );

  // 新增customer字段关联到PaymentIntent
  const paymentIntent = await stripe.paymentIntents.create({
    amount: 4444,
    currency: "usd",
    customer: user.stripeCustomerId
  });

  return {
    ephemeralKey: ephemeralKey.secret,
    paymentIntent: paymentIntent.client_secret,
    customerId: user.stripeCustomerId,
  };
}

说明 #

前端传递customerId和临时密钥只是用于Payment Sheet的客户身份验证和信息展示，但付款与客户的绑定逻辑必须在后端创建PaymentIntent时完成。只有当PaymentIntent明确关联了Customer ID，Stripe后台才会将该付款归属到对应的客户名下。
