Question

我正在尝试实施直接付款方式，因为我在我的数据库中有用户的信用卡信息等。这是我所指的样本：

using System;
using System.Collections.Generic;
using System.Text;
using com.paypal.sdk.services;
using com.paypal.sdk.profiles;
using com.paypal.sdk.util;
using com.paypal.soap.api;

namespace ASPDotNetSamples
{
    public class DoDirectPayment
    {
        public DoDirectPayment()
        {
        }
        public string DoDirectPaymentCode(string paymentAction, string amount, string creditCardType, string creditCardNumber, string expdate_month, string cvv2Number, string firstName, string lastName, string address1, string city, string state, string zip, string countryCode, string currencyCode)
        {

            com.paypal.soap.api.DoDirectPaymentReq req = new com.paypal.soap.api.DoDirectPaymentReq();


            NVPCallerServices caller = new NVPCallerServices();
            IAPIProfile profile = ProfileFactory.createSignatureAPIProfile();
            /*
             WARNING: Do not embed plaintext credentials in your application code.
             Doing so is insecure and against best practices.
             Your API credentials must be handled securely. Please consider
             encrypting them for use in any production environment, and ensure
             that only authorized individuals may view or modify them.
             */

            // Set up your API credentials, PayPal end point, API operation and version.
            profile.APIUsername = "sdk-three_api1.sdk.com";
            profile.APIPassword = "QFZCWN5HZM8VBG7Q";
            profile.APISignature = "AVGidzoSQiGWu.lGj3z15HLczXaaAcK6imHawrjefqgclVwBe8imgCHZ";
            profile.Environment = "sandbox";
            caller.APIProfile = profile;

            NVPCodec encoder = new NVPCodec();
            encoder["VERSION"] = "51.0";
            encoder["METHOD"] = "DoDirectPayment";

            // Add request-specific fields to the request.
            encoder["PAYMENTACTION"] = paymentAction;
            encoder["AMT"] = amount;
            encoder["CREDITCARDTYPE"] = creditCardType;
            encoder["ACCT"] = creditCardNumber;
            encoder["EXPDATE"] = expdate_month;
            encoder["CVV2"] = cvv2Number;
            encoder["FIRSTNAME"] = firstName;
            encoder["LASTNAME"] = lastName;
            encoder["STREET"] = address1;
            encoder["CITY"] = city;
            encoder["STATE"] = state;
            encoder["ZIP"] = zip;
            encoder["COUNTRYCODE"] = countryCode;
            encoder["CURRENCYCODE"] = currencyCode;

            // Execute the API operation and obtain the response.
            string pStrrequestforNvp = encoder.Encode();
            string pStresponsenvp = caller.Call(pStrrequestforNvp);

            NVPCodec decoder = new NVPCodec();
            decoder.Decode(pStresponsenvp);
            return decoder["ACK"];

        }
    }
}

然而，我收到错误'NVPCallerServices'无法找到。我已经参考了paypal_base。谁能告诉我这是什么问题？

Answer 1

是的，那就是Pay Pal API :)

样本可能有点过时了。 NVPCallerServices类现在似乎被命名为CallerServices。

因此，请尝试替换

行

NVPCallerServices caller = new NVPCallerServices();

带

CallerServices caller = new CallerServices();
