如何从Paypal调用DoDirectPayment API调用

Question

首先，这涉及桌面应用程序而不是ASP .Net应用程序。

我已经为我的项目添加了一个Web引用，并构建了各种数据对象，如PayerInfo，Address和CreditCard。问题是，我如何实际调用DoDirectPaymentRequest并传入对象？根据文档，我使用CallerService和ProfileFactory对象，但我没有这些可用。

我是如何从EXE调用API的？

此致

在项目中使用服务参考而不是Web参考。 您应该创建 PayPalAPIInterfaceClient 或 PayPalAPIAAInterfaceClient 的实例。之后，您将能够调用DoDirectPayment。

示例：

        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);
        }
