c# - 在C#中为PayPal身份验证 header 生成签名

我的目标是代表第三方商家将发票发送到另一个Paypal帐户。我正在使用权限服务来成功获取权限，从而产生访问令牌和关联的机密。

但是，我不理解在创建/发送发票时如何使用访问令牌和关联的机密来构建标题。

我正在使用C# .NET Invoicing SDK与Invoicing Service API进行通信。

这是我用来创建和发送发票的代码。

RequestEnvelope envelopeRequest = new RequestEnvelope();
envelopeRequest.errorLanguage = "en_GB";

List<InvoiceItemType> invoiceItemList = new List<InvoiceItemType>();

InvoiceItemType invoiceItem = new InvoiceItemType("Item", Convert.ToDecimal("2"), Convert.ToDecimal("4.00"));
invoiceItemList.Add(invoiceItem);

InvoiceItemListType itemList = new InvoiceItemListType(invoiceItemList);

InvoiceType invoice = new InvoiceType("[email protected]", "[email protected]", itemList, "USD");

CreateAndSendInvoiceRequest requestCreateAndSendInvoice = new CreateAndSendInvoiceRequest(envelopeRequest, invoice);

InvoiceService service = new InvoiceService();

responseCreateAndSendInvoice = service.CreateAndSendInvoice(requestCreateAndSendInvoice);

最佳答案

在黑暗中摸索了一段时间之后，我发现.NET Invoicing SDK负责创建标头。 InvoiceService有两种将令牌和秘密分配给标头的方法。有关详情，请参见下文。

RequestEnvelope envelopeRequest = new RequestEnvelope();
envelopeRequest.errorLanguage = "en_GB";

List<InvoiceItemType> invoiceItemList = new List<InvoiceItemType>();

InvoiceItemType invoiceItem = new InvoiceItemType("Item", Convert.ToDecimal("2"), Convert.ToDecimal("4.00"));
invoiceItemList.Add(invoiceItem);

InvoiceItemListType itemList = new InvoiceItemListType(invoiceItemList);

InvoiceType invoice = new InvoiceType("[email protected]", "[email protected]", itemList, "USD");

CreateAndSendInvoiceRequest requestCreateAndSendInvoice = new CreateAndSendInvoiceRequest(envelopeRequest, invoice);

Dictionary<string, string> list = new Dictionary<string, string>();
list.Add("mode", "sandbox");
list.Add("account1.apiUsername", "contact-facilitator_api1.testdomain.com");
list.Add("account1.apiPassword", "xxxx");
list.Add("account1.apiSignature", "xxxx--xxx");

InvoiceService service = new InvoiceService(list);

service.SetAccessToken(accessToken);
service.SetAccessTokenSecret(secret);

responseCreateAndSendInvoice = service.CreateAndSendInvoice(requestCreateAndSendInvoice);
