如何只允许借记卡进行谷歌钱包整合Android

Question

我想只接受借记卡使用Google电子钱包付款，我没有找到任何有用的文章或解决方案。

以下是我遵循的代码示例：

private PaymentDataRequest createPaymentDataRequest() {
    PaymentDataRequest.Builder request =
            PaymentDataRequest.newBuilder()
                    .setTransactionInfo(
                            TransactionInfo.newBuilder()
                                    .setTotalPriceStatus(WalletConstants.TOTAL_PRICE_STATUS_FINAL)
                                    .setTotalPrice("10.00")
                                    .setCurrencyCode("USD")
                                    .build())
                    .addAllowedPaymentMethod(WalletConstants.PAYMENT_METHOD_CARD)
                    .addAllowedPaymentMethod(WalletConstants.PAYMENT_METHOD_TOKENIZED_CARD)
                    .setCardRequirements(
                            CardRequirements.newBuilder()
                                    .addAllowedCardNetworks(
                                            Arrays.asList(
                                                    WalletConstants.CARD_NETWORK_AMEX,
                                                    WalletConstants.CARD_NETWORK_DISCOVER,
                                                    WalletConstants.CARD_NETWORK_VISA,
                                                    WalletConstants.CARD_NETWORK_MASTERCARD))
                                    .setAllowPrepaidCards(false)
                                    .build());

    PaymentMethodTokenizationParameters params =
            PaymentMethodTokenizationParameters.newBuilder()
                    .setPaymentMethodTokenizationType(
                            WalletConstants.PAYMENT_METHOD_TOKENIZATION_TYPE_PAYMENT_GATEWAY)
                    .addParameter("gateway", "xxxx")
                    .addParameter("gatewayMerchantId", "xxxxxxx")
                    .build();

    request.setPaymentMethodTokenizationParameters(params);
    return request.build();
}

任何建议都将受到高度赞赏。

提前致谢。

目前无法过滤掉Google Pay API中的信用卡。

但是，您可以使用getCardClass()从意图中收到PaymentData后检查卡片类型：

PaymentData paymentData = PaymentData.getFromIntent(intent);
if (paymentData.getCardInfo().getCardClass() != WalletConstants.CARD_CLASS_DEBIT) {
    // show error to user
}
