REST payment.create不创建支付

Question

我有一个后端web服务(不是网页)，它试图从前端客户端创建一个支付。在一些细节和事务列表之间没有数据匹配的地方，我从沙坑那里得到了适当的错误消息，解释了出了什么问题后，我最终得到了payment.create方法来执行，而没有抛出异常。不幸的是，虽然我可以看到测试web服务和paypal之间存在SSL通信，但是当例程返回时，我没有链接，也没有创建状态。我可能完全误解了api的机制，但是在调用中没有任何错误或异常的情况下，我有点困惑。

下面是我使用的代码：

    var config = ConfigManager.Instance.GetProperties();
    var clientid = config[BaseConstants.ClientId];
    var clientSecret = config[BaseConstants.ClientSecret];
    var accessToken = new OAuthTokenCredential(clientid, clientSecret, config).GetAccessToken();
    var apiContext = new APIContext(accessToken);
    var itemList = new ItemList() { items = new List<Item>() };
    using (var context = new PETTEntities3())
    {
      SubscriptionType subType = context.SubscriptionTypes.FirstOrDefault(s => s.SubscriptionTypeID == Subscription.SubscriptionTypeID);
      itemList.items.Add(new Item()
      {
        name = subType.SubscriptionName,
        currency = "NZD",
        price = (Subscription.Amount / (decimal)1.15).ToString("0.00"),
        quantity = "1",
        sku = subType.SubscriptionTypeID.ToString()
       });
       var payer = new Payer() { payment_method = "paypal" };
       var redirectUrls = new RedirectUrls()
       {
         cancel_url = ConfigurationManager.AppSettings["PaymentConfirmationURL"] + Subscription.PaymentApprovalID,
           return_url = ConfigurationManager.AppSettings["PaymentCancellationURL"] + Subscription.PaymentApprovalID
       };
       var details = new Details()
       {
         tax = (Subscription.Amount - decimal.Parse((Subscription.Amount / (decimal)1.15).ToString("0.00"))).ToString("0.00"),
         subtotal = (Subscription.Amount / (decimal)1.15).ToString("0.00"),
         shipping="0"
        };
        var amount = new Amount()
        {
          currency = "NZD",
          total = Subscription.Amount.ToString("0.00"),
          details = details              
        };
        var transactionList = new List<Transaction>();
        transactionList.Add(new Transaction()
        {
          description = "PETT Subscription.",
          invoice_number = "PETT1420" + Subscription.SubscriptionID.ToString(),
          amount = amount,
          item_list = itemList
        });
        Payment payment = new Payment()
        {
          intent = "sale",
          payer = payer,
          transactions = transactionList,
          redirect_urls = redirectUrls
        };
        payment.Create(apiContext);
.... At this point the payment state is still null and no links are present even though I appear to have a successful call with no exceptions.

任何关于我所缺少的线索或洞察力都将不胜感激。

啊，太明显了。没有注意到函数签名payment.create，它返回了一个新的支付。这是您需要使用的，而不是用于调用创建的付款：

支付paymentToUse = payment.Create(apiContext)；

paymentToUse把所有的货物都买好了。
