【中文标题】在 PayPal SandBox，MVC 中创建付款时出现 INTERNAL_SERVICE_ERROR【英文标题】：INTERNAL_SERVICE_ERROR while creating payment in PayPal SandBox, MVC 【发布时间】：2015-04-13 10:42:41 【问题描述】：

我的想法已经用完了，类似问题的答案都没有帮助，因此我现在很绝望。我正在尝试将贝宝付款集成到我的应用程序中。我已在我的沙盒帐户中将负面测试设置为关闭。我正在使用 Visual Studio 2013，这是我的示例代码：

Address billingAddress = new Address();
billingAddress.line1 = "52 N Main ST";
billingAddress.city = "Johnstown";
billingAddress.country_code = "US";
billingAddress.postal_code = "43210";
billingAddress.state = "OH";

CreditCard creditCard = new CreditCard();
creditCard.number = "4417119669820331";
creditCard.type = "visa";
creditCard.expire_month = 11;
creditCard.expire_year = 2018;
creditCard.cvv2 = "874";
creditCard.first_name = "Joe";
creditCard.last_name = "Shopper";
creditCard.billing_address = billingAddress;

var amountDetails = new Details();
amountDetails.subtotal = "7.41";
amountDetails.tax = "0.03";
amountDetails.shipping = "0.03";

Amount amount = new Amount();
amount.total = "7.47";
amount.currency = "USD"; 
amount.details = amountDetails;

Transaction transaction = new Transaction();
transaction.amount = amount;
transaction.description = "This is the payment transaction description.";

List<Transaction> transactions = new List<Transaction>();
transactions.Add(transaction);

FundingInstrument fundingInstrument = new FundingInstrument();
fundingInstrument.credit_card = creditCard;

List<FundingInstrument> fundingInstruments = new List<FundingInstrument>();
fundingInstruments.Add(fundingInstrument);

Payer payer = new Payer();
payer.funding_instruments = fundingInstruments;
payer.payment_method = "credit_card";

Payment payment = new Payment();
payment.intent = "sale";
payment.payer  = payer;
payment.transactions = transactions;

var config = ConfigManager.Instance.GetProperties();
var accessToken = new OAuthTokenCredential(config).GetAccessToken();

        try
        
            var apiContext = new APIContext(accessToken);
            var createdPayment = payment.Create(apiContext);
        
        catch (PayPal.HttpException e)
        
            return Json(e.InnerException, JsonRequestBehavior.AllowGet);

现在每次我尝试创建付款时，我都会收到以下信息：

"\"name\":\"INTERNAL_SERVICE_ERROR\",\"message\":\"An internal service error has occurred\",\"information_link\":\"https://developer.paypal.com/webapps/developer/docs/api/#INTERNAL_SERVICE_ERROR\",\"debug_id\":\"f0d2f70ac4693\""

debug_id 每次尝试都会更改。任何帮助将不胜感激。

【参考方案1】：

尝试将您使用的信用卡号码更改为其他号码。最近几周，这个错误在 PayPal 的沙盒环境中发生了很多，并且（大部分时间）与过度使用信用卡号有关。最好的尝试是通过开发者仪表板创建一个新的沙盒测试帐户，并在那里生成一个新的信用卡号。

PayPal 支付团队目前正在研究沙盒解决方案，以便在发生这种情况时返回更有意义的错误。

编辑：

作为创建新沙盒测试帐户以获取新信用卡号进行测试的替代方法，您还可以尝试 PayPal 技术支持网站上以下常见问题解答中提供的信用卡号生成器：
