在 Braintree Net 如何生成 PaymentNonce

Question

我工作的公司有一个旧版 WinForms 应用程序，销售和客户服务部门使用它来帮助客户创建订单，而不是客户在网站上创建订单。我们想将我们的 CC 支付网关转换为 Braintree，但我不知道如何创建一个 Payment Nonce，以便我可以使用 CC 信息创建一种支付方式。有没有人成功地将 Braintree SDK 集成到 WinForms 项目中？

我尝试创建交易请求，但没有 PaymentNonce。我只使用了使用该客户的默认付款方式的客户 ID。如果

• 有客户
• 有默认付款方式

但是，如果我想为不存在的客户创建交易，或者客户没有用户提供的信用卡的付款方式，那我就难住了。我不知道如何提供 CC 信息以及在什么对象中传递卡数据（编号、到期日期、CVV），Braintree.CreditCard 对象由于其保护级别而无法访问，所以这不是如何传递它. ????‍♂️

以下是我尝试传递信用卡信息的交易：

  transaction = new TransactionRequest()
            {
                Amount = paymentData.Amount,
                CustomerId = customerId,
                DiscountAmount = paymentData.CouponDiscount + paymentData.DiscAmount,
                ShippingAmount = paymentData.ShipCharge,
                LineItems = lineItems.ToArray(),
                TaxAmount = paymentData.Taxes,
                TaxExempt = paymentData.Taxes == 0 ? true : false,
                BillingAddress = new AddressRequest()
                {
                    Company = address.Company,
                    FirstName = paymentData.FirstName,
                    LastName = paymentData.LastName,
                    Locality = address.City,
                    Region = address.State,
                    PostalCode = address.Zip,
                    StreetAddress = address.Address1,
                    ExtendedAddress = address.Address2,
                    CountryCodeAlpha2 = address.CountryCode
                },
                Options = new TransactionOptionsRequest()
                {
                    SubmitForSettlement = paymentData.TransType == "A" ? false : true
                },
                Braintree.CreditCard = new Braintree.CreditCard()
                {
                    CardholderName = paymentData.AccountName,
                    Cvv = paymentData.CVV,
                    ExpirationMonth = paymentData.ExpMonth,
                    ExpirationYear = paymentData.ExpYear,
                    UniqueNumberIdentifier = paymentData.AccountNumber
                },
            };

            var customFields = new Dictionary<string, string>();
            customFields.Add("cartid", paymentData.IsCart ? paymentData.Id.ToString() : "0");
            customFields.Add("orderid", paymentData.IsCart ? "0" : paymentData.Id.ToString());
            customFields.Add("userid", paymentData.CustId);
            transaction.CustomFields = customFields;
  

            Result<Braintree.Transaction> result = GetGateway().Transaction.Sale(transaction);

要在不使用 DropIn 或托管字段的情况下使用 Braintree SDK 创建信用卡交易，您需要先创建信用卡对象，然后再创建交易。

//create the credit card
                var creditCardRequest = new CreditCardRequest
                {
                    CustomerId = customerId,
                    Number = paymentData.AccountNumber,
                    CardholderName = paymentData.AccountName,
                    ExpirationMonth = paymentData.ExpMonth.ToString("d2"),
                    ExpirationYear = paymentData.ExpYear.ToString(),
                    CVV = paymentData.CVV,
                    Options = new CreditCardOptionsRequest()
                    {
                        FailOnDuplicatePaymentMethod = false,
                        VerifyCard = true
                    },
                };
                Result<Braintree.CreditCard> result = GetGateway().CreditCard.Create(creditCardRequest);
                if (result.IsSuccess())
                    creditCard = result.Target;




 transaction = new TransactionRequest()
                {
                    Amount = paymentData.Amount,
                    CustomerId = customerId,
                    PaymentMethodToken = creditCard.Token,
                    DiscountAmount = paymentData.CouponDiscount + paymentData.DiscAmount,
                    ShippingAmount = paymentData.ShipCharge,
                    LineItems = lineItems.ToArray(),
                    TaxAmount = paymentData.Taxes,
                    TaxExempt = paymentData.Taxes == 0 ? true : false,
                    BillingAddress = new AddressRequest()
                    {
                        Company = address.Company,
                        FirstName = paymentData.FirstName,
                        LastName = paymentData.LastName,
                        Locality = address.City,
                        Region = address.State,
                        PostalCode = address.Zip,
                        StreetAddress = address.Address1,
                        ExtendedAddress = address.Address2,
                        CountryCodeAlpha2 = address.CountryCode
                    },
                    Options = new TransactionOptionsRequest()
                    {
                        SubmitForSettlement = paymentData.TransType == "A" ? false : true
                    },
                    TransactionSource = "moto"
                };

                var customFields = new Dictionary<string, string>();
                customFields.Add("cartid", paymentData.IsCart ? paymentData.Id.ToString() : "0");
                customFields.Add("orderid", paymentData.IsCart ? "0" : paymentData.Id.ToString());
                customFields.Add("userid", paymentData.CustId);
                transaction.CustomFields = customFields;
      

                Result<Braintree.Transaction> result = GetGateway().Transaction.Sale(transaction);
                if (result.IsSuccess())
                { //do something here}
