Stripe Java API 投射到客户时出现 Webhook 错误

Question

我找到了这个 post: "" 它告诉你要从 StripeObject 中获取你必须转换的对象类型，比如
Invoice invoice = (Invoice) event.getData().getObject();
Class: StripeWebhook

41    Event event = ApiResource.GSON.fromJson(request.body(), Event.class);
42    if (event.getType().equals("invoice.payment_failed") || event.getType().equals("charge.failed") || event.getType().equals("charge.refunded") || event.getType().equals("customer.subscription.deleted")) {
43 ->     Customer customer = (Customer)event.getData().getObject();`
44        Plan plan = (Plan)event.getData().getObject();
45    }

堆栈跟踪：

我不明白为什么会这样说，因为它从来都不是订阅对象。

Answer 1

您的问题是，如果 webhook 描述了发票、收费或订阅（customer.subscription 描述的是订阅而不是客户 https://stripe.com/docs/api/events/types#event_types-customer.subscription.deleted），您的 if 语句的内容将会执行

在这种情况下，我怀疑您正在接收 customer.subscription.deleted webhook，但随后试图将 Subscription 对象转换为 Customer 对象。

您需要重构代码以分别处理每个对象类型并相应地转换它们。或者，您可以使用 StripeObject 类型，它将自动进行转换：

StripeObject stripeObject = event.getData().getObject();
