【问题描述】：
我正在尝试实施直接付款方式，因为我的数据库中有用户的信用卡信息等。这是我指的示例：
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"];
}
}
}

这很好用，但我唯一的问题是如何处理定期付款？我应该对示例进行哪些更改？
提前致谢:)
【问题讨论】：
-
如果你有他们的信用卡详细信息，为什么不每个月都给你的例程打电话呢？ （或任何频率...）
-
这是个好主意。但是，它需要我自己创建 Windows 服务或任何此类应用程序并处理线程等。如果我的线程错过了在适当的时间运行怎么办。付款是一项关键功能，我不想搞砸它。而不是我认为将这个过程委托给 Paypal 是可取的。
