Stripe - 检索结帐会话的 line_items

Question

我正在尝试获取 Stripe 中结帐会话的 line_items，以便我可以发送一封包含产品下载链接的电子邮件，但不幸的是，当我尝试检索时，line_items我checkout_session得到一个空值。

这是我的代码/pages/api/webhooks/index.ts：

当我尝试登录时，line_items我checkout_session得到一个空值。

如API 参考中所述，会话line_items的 Session 是“可扩展的”并且默认情况下不包含在内。这意味着它们在 Webhook 事件中传递时不包含在对象中，并且您在检索对象时必须通过扩展显式请求该值。

要获取这些，您需要检索会话并请求line_items将其包含在响应中：

const session = await stripe.checkout.sessions.retrieve(
  'cs_test_123', {
  expand: ['line_items']
});
