我正在使用 ASP.NET MVC 4、.NET Braintree Payments API 和 Braintree.js。
这是我为 Braintree 构建的一个简单包装器:
public class PaymentBL
{
private static BraintreeGateway _braintreeGateway = new BraintreeGateway
{
Environment = Braintree.Environment.SANDBOX,
MerchantId = "xxxxxxx",
PublicKey = "xxxxxxxxxxxx",
PrivateKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
};
public Result<Transaction> ChargeCardOnce(decimal amount, string cardholderName, string cardNumber, string expiration,
string cvv)
{
TransactionCreditCardRequest creditCardRequest = new TransactionCreditCardRequest();
creditCardRequest.CardholderName = cardholderName;
creditCardRequest.Number = cardNumber;
creditCardRequest.ExpirationDate = expiration;
creditCardRequest.CVV = cvv;
TransactionOptionsRequest optionsRequest = new TransactionOptionsRequest();
optionsRequest.SubmitForSettlement = true;
TransactionRequest transactionRequest = new TransactionRequest();
transactionRequest.Amount = amount;
transactionRequest.CreditCard = creditCardRequest;
transactionRequest.Options = optionsRequest;
return _braintreeGateway.Transaction.Sale(transactionRequest);
}
/// <summary>
/// Stores a credit card in the Braintree vault. In some cases, will put a $1 temporary charge
/// on the credit card that will come off a few days later.
///
/// From BrainTree: Regardless of card type, any instance where a $1 authorization returns a successful result,
/// we immediately follow-up with an automatic void request to ensure that the transaction will fall off
/// of the cardholder's statement as soon as possible.
/// </summary>
public Result<CreditCard> StoreCustomer(int customerId, string cardholderName, string cardNumber, string expiration, string cvv)
{
//CreditCardAddressRequest addressRequest = new CreditCardAddressRequest();
//addressRequest.PostalCode = postalCode;
CreditCardOptionsRequest optionsRequest = new CreditCardOptionsRequest();
optionsRequest.VerifyCard = true;
optionsRequest.VerificationMerchantAccountId = _braintreeGateway.MerchantId;
CreditCardRequest creditCard = new CreditCardRequest();
creditCard.CustomerId = customerId.ToString();
creditCard.Token = customerId.ToString(); // Use same token to ensure overwrite
creditCard.CardholderName = cardholderName;
creditCard.Number = cardNumber;
creditCard.ExpirationDate = expiration;
creditCard.CVV = cvv;
creditCard.Options = optionsRequest;
return _braintreeGateway.CreditCard.Create(creditCard);
}
/// <summary>
/// Search BrainTree vault to retrieve credit card
/// </summary>
/// <param name="customerId"></param>
public CreditCard GetCreditCardOnFile(int customerId)
{
Customer customer = null;
try
{
customer = _braintreeGateway.Customer.Find(customerId.ToString());
}
catch (Braintree.Exceptions.NotFoundException)
{
return null;
}
if (customer.CreditCards == null || customer.CreditCards.Length == 0)
{
return null;
}
if (customer.CreditCards.Length >= 2)
{
throw new Exception(string.Format("Customer {0} has {1} credit cards",
customerId, customer.CreditCards.Length));
}
return customer.CreditCards[0];
}
}
当我调用此方法时,它可以工作:
Result<Transaction> result = paymentBL.ChargeCardOnce(
2.34m
, formCollection["name"]
, formCollection["number"]
, formCollection["exp"]
, formCollection["cvv"]
);
随后,我可以在 Braintree 仪表板中查看已完成的测试事务。因此,我知道来自 Braintree.js 的加密表单值正确地到达了我的控制器操作,并且我的密钥和商家帐户 ID 都已正确设置。
当我将上述对 ChargeCardOnce 的调用替换为对 StoreCustomer 的以下调用时,我在该行收到 Braintree.Exceptions.AuthorizationExceptionreturn _braintreeGateway.CreditCard.Create(creditCard);
Result<CreditCard> result = paymentBL.StoreCustomer(
systemHost.Customer.CustomerId
, formCollection["name"]
, formCollection["number"]
, formCollection["exp"]
, formCollection["cvv"]
);
来自 Braintree 支持:“您可以在沙盒中创建客户和信用卡,因为它的构建完全反映了生产环境的样子。”
有没有人也经历过这个?我指的是 Braintree 对这个问题的支持,但如果 SO 上的任何人都看到了这一点并且知道解决方案或解决方法,我会松一口气。
