Question

这是我使用信用卡结账的代码。使用PayPal Trans工作正常，但我错过了信用卡转换的东西。

HttpContext CurrContext = HttpContext.Current;    
APIContext apiContext = Configuration.GetAPIContext();    
Item item = new Item();
            item.name = _ItemDescription;
            item.currency = "USD";
            item.price = _Amount;
            item.quantity = "1";
            item.sku = _UPC;

            List<Item> itms = new List<Item>();
            itms.Add(item);
            ItemList itemList = new ItemList();
            itemList.items = itms;

            Address billingAddress = new Address();
            billingAddress.city = ciTxBx.Text;
            billingAddress.country_code = "US";
            billingAddress.line1 = ad1TxBx.Text;
            billingAddress.line2 = ad2TxBx.Text;
            billingAddress.postal_code = pcTxBx.Text;
            billingAddress.state = stRcb.SelectedValue.ToString();

            CreditCard crdtCard = new CreditCard();
            crdtCard.billing_address = billingAddress;
            crdtCard.cvv2 = scTxBx.Text;
            crdtCard.expire_month = Convert.ToInt32(emonthTxBx.Text);
            crdtCard.expire_year = Convert.ToInt32(eyearTxBx.Text);
            crdtCard.first_name = ccfnTxBx.Text;
            crdtCard.last_name = cclnTxBx.Text;
            crdtCard.number = ccnTxBx.Text;
            crdtCard.type = ConvertLower(cctRcb.SelectedValue.ToString());

            Details details = new Details();
            details.tax = "0";
            details.shipping = "0";
            details.subtotal = _Amount;

            Amount amont = new Amount();
            amont.currency = "USD";
            amont.total = _Amount;
            amont.details = details;

            Transaction tran = new Transaction();
            tran.amount = amont;
            tran.description = _ItemDescription;
            tran.item_list = itemList;

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

            FundingInstrument fundInstrument = new FundingInstrument();
            fundInstrument.credit_card = crdtCard;

            List<FundingInstrument> fundingInstrumentList = new List<FundingInstrument>();
            fundingInstrumentList.Add(fundInstrument);

            PayerInfo pi = new PayerInfo();
            pi.email = emTxBx.Text;
            pi.first_name = fnTxBx.Text;
            pi.last_name = lnTxBx.Text;
            pi.shipping_address = billingAddress;

            Payer payr = new Payer();
            payr.funding_instruments = fundingInstrumentList;
            payr.payment_method = "credit_card";
            payr.payer_info = pi;

            Payment paymnt = new Payment();
            paymnt.intent = "sale";
            paymnt.payer = payr;
            paymnt.transactions = transactions;
            try
            {
                Payment createdPayment = paymnt.Create(apiContext);
                CurrContext.Items.Add("ResponseJson", JObject.Parse(createdPayment.ConvertToJson()).ToString(Formatting.Indented));
            }
            catch (PayPal.Exception.PayPalException ex)
            {
                if (ex.InnerException is PayPal.Exception.ConnectionException)
                {
                    CurrContext.Response.Write(((PayPal.Exception.ConnectionException)ex.InnerException).Response);
                }
                else
                {
                    CurrContext.Response.Write(ex.Message);
                }
            }
            CurrContext.Items.Add("RequestJson", JObject.Parse(paymnt.ConvertToJson()).ToString(Formatting.Indented));

任何人都知道我为什么收到此请求的＃34;无有效负载＆＃34;消息？

在嘲笑你的代码（以及硬编码值）之后，我评论的那一行是唯一能让它工作的东西（我不知道你的代码如何编译/为什么会编译）： / p>

pi.shipping_address = new ShippingAddress
{
   city = "San Mateo",
   country_code = "US",
   line1 = "SO TEST",
   line2 = "",
   postal_code = "94002",
   state = "CA",
 };

最后来自PayPal（ResponseJson）的（成功）回复：
