MVC PayPal整合

Question

我的网站正常运行，因此用户可以通过卡付款但是现在我还需要使用PayPal，我似乎无法将产品从购物车发送到paypal控制器，每个产品都需要在订单中发送。

这是我的PayPal控制器;

namespace T_shirt_Company_v3.Controllers
{
    public class PayPalController : Controller
    {
        public ActionResult RedirectFromPaypal()
        {
            return View();
        }
        public ActionResult CancelFromPaypal()
        {
            return View();
        }
        public ActionResult NotifyFromPaypal()
        {
            return View();
        }



        public ActionResult ValidateCommand(string RecordId, string CartTotal)
        {



            bool useSandbox = Convert.ToBoolean(ConfigurationManager.AppSettings["IsSandbox"]);
            var paypal = new PayPal(useSandbox);


            paypal.item_name = RecordId;
            paypal.amount = CartTotal;
            return View(paypal);
        }
    }
}

我的结帐视图，我需要详细信息;

@model T_shirt_Company_v3.ViewModels.ShoppingCartViewModel

@{
    ViewBag.Title = "Shopping Cart";
}
<script src="/Scripts/jquery-1.4.4.min.js"
        type="text/javascript"></script>
<script type="text/javascript">
    $(function () {
        // Document.ready -> link up remove event handler
        $(".RemoveLink").click(function () {
            // Get the id from the link
            var recordToDelete = $(this).attr("data-id");
            if (recordToDelete != '') {
                // Perform the ajax post
                $.post("/ShoppingCart/RemoveFromCart", {"id": recordToDelete },
                    function (data) {
                        // Successful requests get here
                        // Update the page elements
                        if (data.ItemCount == 0) {
                            $('#row-' + data.DeleteId).fadeOut('slow');
                        } else {
                            $('#item-count-' + data.DeleteId).text(data.ItemCount);
                        }
                        $('#cart-total').text(data.CartTotal);
                        $('#update-message').text(data.Message);
                        $('#cart-status').text('Cart (' + data.CartCount + ')');
                    });
            }
        });
    });

Answer 1

假设我正确阅读了你的代码，你只是渲染数据，而你根本就没有发送它。

• 您的form只有button（这是唯一发送的“数据”）
• 您需要将您呈现的数据包含为form字段（<input />）

H个。

Answer 2

由于PayPal Api依赖于在使用之前必须理解的一组操作，开发人员应该专注于理解操作摘要，在使用Api之前，在正式使用Api之前还可以使用沙箱进行测试。

您应该知道如何使用PayPal的RESTful端点结构。

您可以查看PayPal Api文档，详细了解如何使用REST API Reference.
