paypal - 什么是有效的支付方式 token ？

Question

我正在尝试创建一张信用卡，因此我需要调用 paymentMethodNone()。根据文档我可以

Use PaymentMethod.create() to create a payment method for an existing customer:

// It's not clear what A_PAYMENT_METHOD_TOKEN has to be
Result<PaymentMethodNonce> result = bt.paymentMethodNonce()
                                      .create("A_PAYMENT_METHOD_TOKEN");

String nonceFromTheClient = result.getTarget().getNonce();
Customer customer = customerResult.getTarget();

PaymentMethodRequest paymentMethodRequest = new PaymentMethodRequest()
        .customerId(customer.getId())
        .paymentMethodNonce(nonceFromTheClient);

Result<? extends PaymentMethod> paymentMethodResult = bt.paymentMethod()
                                                        .create(paymentMethodRequest);

PaymentMethod paymentMethod = paymentMethodResult.getTarget();

但是，文档中没有关于有效 token 的信息。都不是here也不here - 还是我只是瞎了眼？

您不需要 payment_method_token 来创建 PaymentMethod。

要创建信用卡，您需要创建一个 PaymentMethod .首先，从传入请求中检索 payment_method_nonce。接下来，使用 PaymentMethodRequest 创建 PaymentMethod。

//payment_method_nonce will be a post parameter in the request
//set nonceFromTheClient to equal payment_method_nonce
PaymentMethodRequest paymentMethodRequest = new PaymentMethodRequest()
            .customerId(customer.getId())
            .paymentMethodNonce(nonceFromTheClient);
Result<? extends PaymentMethod> result = gateway.paymentMethod().create(request);
