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"];

        }
    }
}

这样可以正常但我唯一的问题是如何处理这种重复付款？我应该在样本中做出哪些改变？

提前致谢：）

Answer 1

检查PayPal API Reference.

有一个名为CreateRecurringPaymentsProfile

的方法

另请阅读Handling Recurring Payments

如何更改此代码以处理定期付款？
