Java 使用现有客户付款方式(卡)创建 Stripe 订阅

我无法在客户已有付款方式的情况下创建订阅.仪表板在新的订阅对象旁边只有一个"不完整"标记.

下面的端点接受客户ID和支付方法ID.其中大部分是从他们的示例中提取出来的，但我在其中添加了".setDefaultPaymentMethod"

@GetMapping("/subscriptions/create/{customerId}/{defaultPaymentMethod}")
public void createSubscription(@PathVariable String customerId, @PathVariable String defaultPaymentMethod) throws StripeException {

    Stripe.apiKey = "sk_test_XXXXX";
    String priceId = "XXXXX";

    // Automatically save the payment method to the subscription
    // when the first payment is successful.
    SubscriptionCreateParams.PaymentSettings paymentSettings =
            SubscriptionCreateParams.PaymentSettings
                    .builder()
                    .setSaveDefaultPaymentMethod(SubscriptionCreateParams.PaymentSettings.SaveDefaultPaymentMethod.ON_SUBSCRIPTION)
                    .build();

    // Create the subscription. Note we're expanding the Subscription's
    // latest invoice and that invoice's payment_intent
    // so we can pass it to the front end to confirm the payment
    SubscriptionCreateParams.Builder subCreateParams = SubscriptionCreateParams.builder()
            .setCustomer(customerId)
            .addItem(
                    SubscriptionCreateParams
                            .Item.builder()
                            .setPrice(priceId)
                            .build()
            )
            .setPaymentSettings(paymentSettings)
            .setDefaultPaymentMethod(defaultPaymentMethod)
            .setPaymentBehavior(SubscriptionCreateParams.PaymentBehavior.DEFAULT_INCOMPLETE)
            .setCollectionMethod(SubscriptionCreateParams.CollectionMethod.CHARGE_AUTOMATICALLY)
            .addAllExpand(Arrays.asList("latest_invoice.payment_intent"));

    Subscription subscription = Subscription.create(subCreateParams.build());
}

请注意，如果我最初从我的终结点创建订阅，并获得客户端秘密，该秘密用于通过Stride JavaScript/Reaction库收集支付信息，并让用户通过"stripe.confirmCardPayment"提交这些支付详细信息，则我能够创建成功的订阅.终结点如下:

@GetMapping("/subscriptions/create/{customerId}")
public void receiveCreateSubscriptionRequestWithoutPaymentMethod(@PathVariable String customerId) throws StripeException {

    Stripe.apiKey = "sk_test_XXXXX";
    String priceId = "XXXXX";

    // Automatically save the payment method to the subscription
    // when the first payment is successful.
    SubscriptionCreateParams.PaymentSettings paymentSettings =
            SubscriptionCreateParams.PaymentSettings
                    .builder()
                    .setSaveDefaultPaymentMethod(SubscriptionCreateParams.PaymentSettings.SaveDefaultPaymentMethod.ON_SUBSCRIPTION)
                    .build();

    // Create the subscription. Note we're expanding the Subscription's
    // latest invoice and that invoice's payment_intent
    // so we can pass it to the front end to confirm the payment
    SubscriptionCreateParams.Builder subCreateParams = SubscriptionCreateParams.builder()
            .setCustomer(customerId)
            .addItem(
                    SubscriptionCreateParams
                            .Item.builder()
                            .setPrice(priceId)
                            .build()
            )
            .setPaymentSettings(paymentSettings)
            .setPaymentBehavior(SubscriptionCreateParams.PaymentBehavior.DEFAULT_INCOMPLETE)
            .setCollectionMethod(SubscriptionCreateParams.CollectionMethod.CHARGE_AUTOMATICALLY)
            .addAllExpand(Arrays.asList("latest_invoice.payment_intent"));

    Subscription subscription = Subscription.create(subCreateParams.build());
}

有什么 idea 吗？
