当我收到Stripe的webhook，说已经创建了订阅时，我正在尝试更新我的数据库，让该用户访问我的订阅服务。webhook说已经创建了一个订阅，所以我获取UserID并使用它在数据库中查找用户。然后我更新用户记录，将SubscriptionStatus更改为1，表示它处于活动状态。当我试图将该信息保存到数据库时，它会抛出一个异常，我从Stripe收到一个错误，说webhook失败，出现错误400(错误请求(。根据Stripe的回应；由于语法不正确，服务器无法理解该请求">
这是我从Stripe:收到的回复

问题可能是由于数据库逻辑出现问题，导致服务器将完整错误返回给Stripe，Stripe无法读取。相反，您应该提前返回一个200，以指示收到了webhook事件，然后处理您的业务逻辑：https://stripe.com/docs/webhooks/build#return-a-2xx-status-cod-fast
