.net - PayPal - 付款摘要不显示“设置付款选项”设置的项目

Question

我正在使用 PayPal SDK for .Net 来处理自适应支付。 我正在尝试使用 SetPaymentOptions 方法来设置我希望在“付款摘要”部分中显示的项目，但是，当我使用从“付款”方法收到的付款 key 将网站重定向到沙箱审批页面时，付款摘要仅显示一行写着“服务商帐户的测试商店”和总金额。

响应返回成功代码，此外我还看到页面上显示了其他参数，例如 BuisnessName(在 DisplayOptions 中)。

以下是我尝试执行的代码(参数被映射到实际帐户、网址、金额等的实际值替换)。 谁能告诉我我做错了什么？

谢谢!

我正在使用带有嵌入式结账功能的自适应链式支付。

使用自适应付款时，您无法自定义超出已完成的付款页面。

我花了很多时间与 PayPal 通电话讨论这个话题。您在付款选项中设置的 SenderOptions、ReceiverOptions 和 InvoiceData 信息仅在即时付款通知中可用。好消息是 IPN 很容易实现。

http://www.codeproject.com/Tips/84538/Setting-up-PayPal-Instant-Payment-Notification-IPN

您可以解析 IPN 信息并向买家和卖家发送电子邮件。

如果您希望 PayPal 的电子邮件包含任何其他信息，您只能使用 PaymentRequest 的备注字段。在您的示例中:

reqPay.sender = new SenderIdentifier();
reqPay.sender.email = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a7d4c2c9c3c2d5e7cac6cecb89c4c8ca" rel="noreferrer noopener nofollow">[email protected]</a>";
string memo = "Item: " + item_name + " " + item_price + SOME_NONSENSE_DELIMITER;
requestPay.memo = memo;
PayResponse responsePay = service.Pay(reqPay);

需要 SOME_NONSENSE_DELIMITER 来充当行尾，因为不幸的是，换行符和 html 会被忽略，但至少在 PayPal 与接收者的通信中会显示一些内容。
