Question

我正在尝试将Paypal支付整合到.NET 4.0 C＃WinForm应用程序中，执行DirectPayment（无需使用paypal网站打开浏览器），从webMethod调用此方法的asmx webservices

public DoDirectPaymentResponseType DoDirectPaymentAPIOperation(string 
    amountinUSDollar, string creditCardType, string creditCardNumber, int 
    exp_month, int exp_year, string firstName, string middleName, string 
    lastName, string address1, string address2, string city, string state, 
    string zip, string phoneNumber, string CVV2)
{
    DoDirectPaymentResponseType response = new 
    DoDirectPaymentResponseType();
    DoDirectPaymentReq wrapper = new DoDirectPaymentReq();
    DoDirectPaymentRequestType request = new DoDirectPaymentRequestType();
    DoDirectPaymentRequestDetailsType requestDetails = new 
        DoDirectPaymentRequestDetailsType();
    requestDetails.PaymentAction = (PaymentActionCodeType)               
        Enum.Parse(typeof(PaymentActionCodeType), "SALE");
    CreditCardDetailsType creditCard = new CreditCardDetailsType();
    PayerInfoType cardOwner = new PayerInfoType();
    PersonNameType payer = new PersonNameType();
    payer.FirstName = firstName;
    payer.MiddleName = middleName;
    payer.LastName = lastName;
    cardOwner.PayerName = payer;
    creditCard.CardOwner = cardOwner;
    creditCard.CreditCardNumber = creditCardNumber; 
    if (creditCardType == "VISA")
    {
        creditCard.CreditCardType = CreditCardTypeType.VISA;
    }
    else if (creditCardType == "MasterCard")
    {
        creditCard.CreditCardType = CreditCardTypeType.MASTERCARD;
    }
    creditCard.CVV2 = CVV2;
    creditCard.ExpMonth = exp_month;
    creditCard.ExpYear = exp_year;
    requestDetails.PaymentDetails = new PaymentDetailsType();
    requestDetails.PaymentDetails.NotifyURL = "http://IPNhost";
    BasicAmountType paymentAmount = new 
        BasicAmountType(CurrencyCodeType.USD, amountinUSDollar);
    requestDetails.PaymentDetails.OrderTotal = paymentAmount;
    wrapper.DoDirectPaymentRequest = request;
    Dictionary<string, string> config = getConfigDict();
    PayPalAPIInterfaceServiceService service = new 
        PayPalAPIInterfaceServiceService(config);
    response = service.DoDirectPayment(wrapper);
}

当它尝试调用API时，在代码的最后一行我收到此错误： “HttpConnection中的异常执行：无效的HTTP响应请求被中止：无法创建SSL / TLS安全通道。”} System.Exception {PayPal.Exception.PayPalException}。

我有一个集成了Paypal的.NET 4.5 WebForm Web应用程序，我必须在其中定义

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

在其Global.asax文件中，它解决了该特定应用程序的问题，我发现我必须使用此

ServicePointManager.SecurityProtocol = (SecurityProtocolType) 3072;

对于.NET 4.0，但我的问题是：

如果这可能是问题的解决方案，我应该把这一行放在我的代码中？因为我的asmx webservice中没有Global.asax。

根据OP中的评论概述上述报告问题的来源。抛出异常是因为NotifyURL不在https。
