我如何从Paypal调用DoDirectPayment API调用

Question

首先，这与桌面应用程序有关，而不与ASP .Net应用程序有关。

我向项目添加了Web参考，并建立了各种数据对象，例如PayerInfo，Address和CreditCard。 问题是，我实际上该如何调用DoDirectPaymentRequest并传入对象？ 根据文档，我使用CallerService和ProfileFactory对象，但是我没有这些可用。

任何想法，我怎么从EXE调用API？

在项目中使用Service Reference而不是Web Reference。 您应该创建PayPalAPIInterfaceClient或PayPalAPIAAInterfaceClient的实例。 之后，您将可以调用DoDirectPayment。

例：

        DoDirectPaymentResponseType result;
        using (_client = new PayPalAPIAAInterfaceClient())
        {

            DoDirectPaymentRequestType pp_Request = new DoDirectPaymentRequestType();
            pp_Request.Version = _version;
            pp_Request.DoDirectPaymentRequestDetails = new DoDirectPaymentRequestDetailsType();
            pp_Request.DoDirectPaymentRequestDetails.IPAddress = ipAddress;
            pp_Request.DoDirectPaymentRequestDetails.CreditCard = new CreditCardDetailsType();
            pp_Request.DoDirectPaymentRequestDetails.CreditCard.CreditCardNumber = CCNum;

            // ..FILL DATA

            // NOTE: The only currency supported by the Direct Payment API at this time is US dollars (USD).
            pp_Request.DoDirectPaymentRequestDetails.PaymentDetails.OrderTotal.currencyID = CurrencyCodeType.USD;
            pp_Request.DoDirectPaymentRequestDetails.PaymentDetails.OrderTotal.Value = amountOfUSD;

            var dp = new DoDirectPaymentReq
            {
                DoDirectPaymentRequest = pp_Request
            };

            var credentials = new CustomSecurityHeaderType
            {
                Credentials = new UserIdPasswordType
                {
                    Username = _username,
                    Password = _password,
                    Signature = _signature,
                    AppId = ApiId
                }
             };

            result = _client.DoDirectPayment(ref credentials, dp);
        }
