【问题描述】：

我正在使用来自 msdn 的 ASP.NET(Web-Form) 和 WingtipToys 教程编写一个商店应用程序。

我在使用 paypal 按钮时遇到问题。我有错误：

10401
Transaction refused because of an invalid argument. See additional error messages for details.
Order total is invalid.

这是我认为有问题的代码的一部分：

public bool ShortcutExpressCheckout(string amt, ref string token, ref string retMsg)
{
    if (bSandbox)
    {
        pEndPointURL = pEndPointURL_SB;
        host = host_SB;
    }

    string returnURL = "https://localhost:44317/Checkout/CheckoutReview.aspx";
    string cancelURL = "https://localhost:44317/Checkout/CheckoutCancel.aspx";

    NVPCodec encoder = new NVPCodec();
    encoder["METHOD"] = "SetExpressCheckout";
    encoder["RETURNURL"] = returnURL;
    encoder["CANCELURL"] = cancelURL;
    encoder["BRANDNAME"] = "Shop";
    encoder["PAYMENTREQUEST_0_AMT"] = amt;
    encoder["PAYMENTREQUEST_0_ITEMAMT"] = amt;
    encoder["PAYMENTREQUEST_0_PAYMENTACTION"] = "Sale";
    encoder["PAYMENTREQUEST_0_CURRENCYCODE"] = "PLN";

    // Get the Shopping Cart Products
    using (Shop.Logic.ShoppingCartActions myCartOrders = new Shop.Logic.ShoppingCartActions())
    {
        List<ElementKoszyka> myOrderList = myCartOrders.GetCartItems();

        for (int i = 0; i < myOrderList.Count; i++)
        {
            encoder["L_PAYMENTREQUEST_0_NAME" + i] = myOrderList[i].Produkt.nazwa_produkt.ToString();
           // string tmp = Math.Round(myOrderList[i].Produkt.cena, 2).ToString();
           // encoder["L_PAYMENTREQUEST_0_AMT" + i] = Math.Round(myOrderList[i].Produkt.cena, 2).ToString();
            encoder["L_PAYMENTREQUEST_0_AMT" + i] = "22.50";
            encoder["L_PAYMENTREQUEST_0_QTY" + i] = myOrderList[i].ilosc.ToString();
        }
    }

    string pStrrequestforNvp = encoder.Encode();
    string pStresponsenvp = HttpCall(pStrrequestforNvp);

    NVPCodec decoder = new NVPCodec();
    decoder.Decode(pStresponsenvp);

    string strAck = decoder["ACK"].ToLower();
    if (strAck != null && (strAck == "success" || strAck == "successwithwarning"))
    {
        token = decoder["TOKEN"];
        string ECURL = "https://" + host + "/cgi-bin/webscr?cmd=_express-checkout" + "&token=" + token;
        retMsg = ECURL;
        return true;
    }
    else
    {
        retMsg = "ErrorCode=" + decoder["L_ERRORCODE0"] + "&" +
            "Desc=" + decoder["L_SHORTMESSAGE0"] + "&" +
            "Desc2=" + decoder["L_LONGMESSAGE0"];
        return false;
    }
}

总订单已永久分配 (22.50)，但仍有问题。

有什么建议吗？

【解决方案1】：

价格分配在

encoder["L_PAYMENTREQUEST_0_AMT" + i] = "22.50";

也许应该是这样的

encoder["L_PAYMENTREQUEST_0_AMT" + i] = myOrderList[i].Produkt.nazwa_price.ToString();

【讨论】：

还是同样的问题 ;)

【解决方案2】：

好的，问题解决了。我必须在不同的班级将 amt 更改为十进制。

所以paypal订单的正确格式是：“xx.xx”

【解决方案3】：

如果您的计算机使用小数点，那么您应该将分配更改为：

encoder["L_PAYMENTREQUEST_0_AMT" + i] = (myOrderList[i].Produkt.nazwa_price.ToString()).Replace(",",".");

我也遇到了同样的问题。原因是波兰的十进制格式不同。要查看要更改的行，请在下面的代码中查找 // 注释：

public bool ShortcutExpressCheckout(string amt, ref string token, ref string retMsg)
{
    if (bSandbox)
    {
        pEndPointURL = pEndPointURL_SB;
        host = host_SB;
    }

    string returnURL = "https://localhost:44304/Checkout/CheckoutReview.aspx";
    string cancelURL = "https://localhost:44304/Checkout/CheckoutCancel.aspx";

    amt = amt.Replace(",",".");  // <---------SOLUTION------------>

    NVPCodec encoder = new NVPCodec();
    encoder["METHOD"] = "SetExpressCheckout";
    encoder["RETURNURL"] = returnURL;
    encoder["CANCELURL"] = cancelURL;
    encoder["BRANDNAME"] = "Wingtip Toys Sample Application";
    encoder["PAYMENTREQUEST_0_AMT"] = amt;
    encoder["PAYMENTREQUEST_0_ITEMAMT"] = amt;
    encoder["PAYMENTREQUEST_0_PAYMENTACTION"] = "Sale";
    encoder["PAYMENTREQUEST_0_CURRENCYCODE"] = "PLN";

    // Get the Shopping Cart Products
    using (WingtipToys.Logic.ShoppingCartActions myCartOrders = new WingtipToys.Logic.ShoppingCartActions())
    {
        List<CartItem> myOrderList = myCartOrders.GetCartItems();

        for (int i = 0; i < myOrderList.Count; i++)
        {
            encoder["L_PAYMENTREQUEST_0_NAME" + i] = myOrderList[i].Product.ProductName.ToString();
            encoder["L_PAYMENTREQUEST_0_AMT" + i] = myOrderList[i].Product.UnitPrice.ToString().Replace(",", ".");  // <---------SOLUTION------------>
            encoder["L_PAYMENTREQUEST_0_QTY" + i] = myOrderList[i].Quantity.ToString();
        }
    }

    string pStrrequestforNvp = encoder.Encode();
    string pStresponsenvp = HttpCall(pStrrequestforNvp);

    NVPCodec decoder = new NVPCodec();
    decoder.Decode(pStresponsenvp);

    string strAck = decoder["ACK"].ToLower();
    if (strAck != null && (strAck == "success" || strAck == "successwithwarning"))
    {
        token = decoder["TOKEN"];
        string ECURL = "https://" + host + "/cgi-bin/webscr?cmd=_express-checkout" + "&token=" + token;
        retMsg = ECURL;
        return true;
    }
    else
    {
        retMsg = "ErrorCode=" + decoder["L_ERRORCODE0"] + "&" +
            "Desc=" + decoder["L_SHORTMESSAGE0"] + "&" +
            "Desc2=" + decoder["L_LONGMESSAGE0"];
        return false;
    }
}
