推荐答案
在firstData网关中实现定期付款，永远，接受来自不安全的网站的代码处理任何与真钱有关的事情。
你不知道是谁给你代码，你不知道它做了什么，你不知道它将资金正确地放入适当的帐户，而不将细节传递给任何第三方。
只能从FirstData获取此类代码 - 否则欺诈的范围很远太大了。请记住，如果您的行为被视为疏忽，您个人可能要承担任何损失的责任 - 从公共论坛获取您的代码肯定会是！
Never, ever, accept code from a insecure website to handle anything to do with real money.
You do not know who is giving you the code, you do not know what it does, you do not know that it places the monies correctly into the appropriate account, without passing the details to any third parties.
Only get such code from FirstData themselves - the scope for fraud otherwise is far too large. And remember, you personally could be liable for any monies lost if your action is seen to be negligent - which getting your code from a public forum would most certainly be!
我使用下面的代码：
on index.aspx
I m using below code:
on index.aspx
public async Task<ActionResult> Index()
{
var amount = "1";
var cardExpirtyDate = "1215";
var cardHolderName = "Card Holder Name";
var cardNumber = "4111111111111111";
var customerId = 23;//Internal purpose to track which customer made the transaction....
//var paymentService = new PaymentService(amount, cardExpirtyDate, cardHolderName, cardNumber, customerId.ToString());
var paymentService = new PaymentService(amount, cardExpirtyDate, cardHolderName, cardNumber, customerId.ToString(), "091515", "091530", "1", "2");
var transactionResult = await paymentService.PostAsync();
if (transactionResult == null) return View();
if (transactionResult.TransactionApproved && !transactionResult.TransactionError
&& transactionResult.CustomerRef == customerId.ToString())
{
//transaction success....
TempData["TRANSACTION_STATUS"] = "APPROVED";
}
else
{
var message = transactionResult.Message;
}
return View();
}
