Braintree API在CreateCard上抛出Braintree. exceptions . authoriza

我使用的是ASP。.NET MVC 4， .NET Braintree Payments API和Braintree.js.

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 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];
    }
}

当我调用这个方法时，它工作了:

            Result<Transaction> result = paymentBL.ChargeCardOnce(
                2.34m
                , formCollection["name"]
                , formCollection["number"]
                , formCollection["exp"]
                , formCollection["cvv"]
            );

随后，我可以在Braintree仪表板中查看完成的测试事务。因此，我知道来自Braintree.js的加密表单值正确到达我的控制器操作，并且我的密钥和商家帐户id都正确设置。

当我用下面的StoreCustomer调用替换上面的ChargeCardOnce调用时，我在return _braintreeGateway.CreditCard.Create(creditCard);

行收到Braintree.Exceptions.AuthorizationException

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

来自Braintree的支持:"您可以在沙箱中创建客户以及信用卡，因为它被构建为准确地反映生产环境的样子。"

有人也有过这样的经历吗?我指的是Braintree对这个问题的支持，但如果有人在SO上看到这个并知道解决方案或变通方法，我会松一口气。

optionsRequest.VerificationMerchantAccountId = _braintreeGateway.MerchantId;
