c# – Braintree API在Sandbox中的CreateCard.Create上抛出Brain

这是我为Braintree构建的一个简单的包装器：

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 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];
    }
}

当我调用这个方法时,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Braintree.js的加密表单值正确地到达我的控制器操作,并且我的密钥和商家帐户ID都已正确设置.

当我使用以下对StoreCustomer的调用将上述调用替换为ChargeCardOnce时,我在返回_braintreeGateway.CreditCard.Create(creditCard)行返回Braintree.Exceptions.AuthorizationException;

Result<CreditCard> result = paymentBL.StoreCustomer(
                systemHost.Customer.CustomerId,formCollection["cvv"]
            );

来自Braintree的支持：“您可以在沙箱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.”

有没有人经历过这个？我指的是Braintree对这个问题的支持,但是如果SO上的任何人看到了这个问题并且知道解决方案或解决方法,我会很放心.
