Question

我正在解析事件webhooks，对于invoice.payment_succeeded事件，我需要获取Invoice对象，Subscription对象和Plan对象：

            if (event.getType().equals("invoice.payment_succeeded")) {
                Invoice invoice = (Invoice) event.getData().getObject();
                Subscription subscription = invoice.getSubscriptionObject();
                Plan plan = subscription.getPlan();

问题是它获取的Subscription对象为空，所以我无法获得计划，但是在webhook json中，发票显然不为空：

Answer 1

它在文档中指出，数据仅包含您的Webhook的relevant object。

在发票的情况下，它仅是发票对象。幸运的是，其中包含您的subscription ID：

"subscription": "sub_Ee8abQjuYiFJXx",

您可以将此ID用作

的retrieve the data

Subscription subscription = Subscription.retrieve("sub_Ee8abQjuYiFJXx");

Answer 2

首先，subscription属性的值可以为null，例如在one-off invoices的情况下。

默认情况下，整个Subscription对象不包括在Invoice对象中，仅包括其标识符。 Invoice对象中包含的Event对象遵循相同的规则。因此，您将需要检索Subscription及其标识符，如here

所述

if (event.getType().equals("invoice.payment_succeeded")) {
    Invoice invoice = (Invoice) event.getData().getObject();
    Subscription subscription = Subscription.retrieve(invoice.getSubscription());
}

仅当预订包含单个计划时，才会设置plan属性。

请注意，检索对象时可以“扩展” Stripe对象。请参阅Stripe API参考的Expanding Objects部分。

来自“发票”对象的“带区订阅”对象为null
