使用 .NET 中的 CyberSource API 取消/退款交易

Question

我正在使用 CyberSource API 作为支付网关。 我浏览了所有可用的文档并提出了以下代码：

1. 首先，我使用 url https://ics2wstest.ic3.com/commerce/1.x/transactionProcessor/CyberSourceTransaction_1.60.ZDD3BDA2F06064AEFDCC0EDE添加了对 CyberSource 的服务引用

2. 然后我添加了以下代码来进行交易然后取消它。 但不知何故，取消似乎不起作用。 我不确定我做错了什么，因为网络上可用的文档很少。

    using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; using PaymentGatewayConsole.CyberSourceTest; namespace PaymentGatewayConsole { class Program { private const String MERCHANT_ID = "removed"; private const String TRANSACTION_KEY = "removed"; private static string REQUEST_TOKEN = string.Empty; private static string REQUEST_ID = string.Empty; static void Main(string[] args) { MakePayment(); RequestRefund(); } private static void MakePayment() { RequestMessage request = new RequestMessage(); request.merchantID = MERCHANT_ID; // replace request.merchantReferenceCode with reference number for the current transaction. request.merchantReferenceCode = "123"; request.clientLibrary = ".NET WCF"; request.clientLibraryVersion = Environment.Version.ToString(); request.clientEnvironment = Environment.OSVersion.Platform + Environment.OSVersion.Version.ToString(); request.ccAuthService = new CCAuthService(); request.ccAuthService.run = "true"; BillTo billTo = new BillTo(); billTo.firstName = "John"; billTo.lastName = "Doe"; billTo.street1 = "1295 Charleston Road"; billTo.city = "Mountain View"; billTo.state = "CA"; billTo.postalCode = "94043"; billTo.country = "US"; billTo.email = "null@cybersource.com"; billTo.ipAddress = "10.7.111.111"; request.billTo = billTo; Card card = new Card(); card.accountNumber = "4111111111111111"; card.expirationMonth = "12"; card.expirationYear = "2020"; card.cardType = "Visa"; request.card = card; PurchaseTotals purchaseTotals = new PurchaseTotals(); purchaseTotals.currency = "USD"; request.purchaseTotals = purchaseTotals; request.item = new Item[1]; Item item = new Item(); item.id = "0"; item.unitPrice = "49.00"; request.item[0] = item; try { TransactionProcessorClient proc = new TransactionProcessorClient(); proc.ChannelFactory.Credentials.UserName.UserName = request.merchantID; proc.ChannelFactory.Credentials.UserName.Password = TRANSACTION_KEY; ReplyMessage reply = proc.runTransaction(request); REQUEST_ID = reply.requestID; REQUEST_TOKEN = reply.requestToken; Console.WriteLine("decision = " + reply.decision); Console.WriteLine("reasonCode = " + reply.reasonCode); Console.WriteLine("requestID = " + reply.requestID); Console.WriteLine("requestToken = " + reply.requestToken); Console.WriteLine("ccAuthReply.reasonCode = " + reply.ccAuthReply.reasonCode); } catch (TimeoutException e) { Console.WriteLine("TimeoutException: " + e.Message + "\n" + e.StackTrace); } catch (FaultException e) { Console.WriteLine("FaultException: " + e.Message + "\n" + e.StackTrace); } catch (CommunicationException e) { Console.WriteLine("CommunicationException: " + e.Message + "\n" + e.StackTrace); } Console.ReadLine(); } /// <summary> /// Method for requesting refund /// </summary> private static void RequestRefund() { RequestMessage request = new RequestMessage(); request.merchantID = MERCHANT_ID; request.merchantReferenceCode = "123"; request.clientLibrary = ".NET WCF"; request.clientLibraryVersion = Environment.Version.ToString(); request.clientEnvironment = Environment.OSVersion.Platform + Environment.OSVersion.Version.ToString(); request.ccAuthService = new CCAuthService(); request.ccAuthService.run = "true"; //request.ccAuthReversalService = new CCAuthReversalService(); //request.ccAuthReversalService.run = "true"; //request.ccAuthReversalService.authRequestID = REQUEST_ID; //request.orderRequestToken = REQUEST_TOKEN; //request.purchaseTotals = new PurchaseTotals(); //request.purchaseTotals.currency = "USD"; //request.purchaseTotals.grandTotalAmount = "10"; VoidService reqVoid = new VoidService(); reqVoid.voidRequestID = REQUEST_ID; reqVoid.voidRequestToken = REQUEST_TOKEN; reqVoid.run = "true"; request.voidService = reqVoid; try { TransactionProcessorClient proc = new TransactionProcessorClient(); proc.ChannelFactory.Credentials.UserName.UserName = request.merchantID; proc.ChannelFactory.Credentials.UserName.Password = TRANSACTION_KEY; ReplyMessage reply = proc.runTransaction(request); Console.WriteLine("decision = " + reply.decision); Console.WriteLine("reasonCode = " + reply.reasonCode); Console.WriteLine("requestID = " + reply.requestID); Console.WriteLine("requestToken = " + reply.requestToken); } catch (TimeoutException e) { Console.WriteLine("TimeoutException: " + e.Message + "\n" + e.StackTrace); } catch (FaultException e) { Console.WriteLine("FaultException: " + e.Message + "\n" + e.StackTrace); } catch (CommunicationException e) { Console.WriteLine("CommunicationException: " + e.Message + "\n" + e.StackTrace); } Console.ReadLine(); } } }

在方法请求退款中，我实际上得到了 Request.ReasonCode = 102 的响应，这意味着错误。 理想情况下它应该是 100。102 表示“请求中的一个或多个字段包含无效数据。”。

非常感谢您的帮助...

尝试这个。 这个对我有用。

            RequestMessage request = new RequestMessage();
            request.ccAuthReversalService = new CCAuthReversalService();
            request.ccAuthReversalService.run = "true";
            request.ccAuthReversalService.authRequestID = order.Transactionno;
            request.ccAuthReversalService.authRequestToken = order.RequestToken;
            request.purchaseTotals = new PurchaseTotals();
            request.purchaseTotals.currency = "USD";
            request.purchaseTotals.grandTotalAmount = (order.Total).ToString("0.00");
            request.merchantID = MerchantId;
            request.merchantReferenceCode = order.OrderNumber;
            TransactionProcessorClient proc = new TransactionProcessorClient();
            proc.ChannelFactory.Credentials.UserName.UserName = request.merchantID;
            proc.ChannelFactory.Credentials.UserName.Password = Key;
            ReplyMessage reply = proc.runTransaction(request);

Answer 2

如果您已经在使用来自初始授权的 requestId，则不需要请求令牌。 因此，您可以安全地删除该行：

request.ccAuthReversalService.authRequestToken = order.RequestToken;

此外，purchaseTotals.currency 不是必需的，通过您的 requestId CyberSource 将为您获取该信息。 另一行保存：

request.purchaseTotals.currency = "USD";

Answer 3

request.ecDebitService = new ECDebitService();
request.ecDebitService.run = "true";

request.ecCreditService = new ECCreditService();
equest.ecCreditService.run = "true";

您可以使用此贷记和借记服务，如果最终用户想要借记一些金额，例如：100.00 美元，他可以输入 - 100.00 美元，然后如果总金额小于零，您可以将贷记服务设置为真，反之亦然。

试试这个，如果您需要更多帮助，请随时通过邮件 ID 与我联系。

Answer 4

一旦您发布了作者，您可以向用户帐户发布信用金额，这将向他/她发送这笔钱。 为此，您需要指定 request.ccCreditService 并将其运行字段设置为 true。 同样的事情也可以在他们的 Business Center UI 中完成。

但是，这与取消实际授权/结算交易无关。
