MVC PayPal集成

我有我的網站工作，所以用戶可以通過卡支付，但現在我也需要使用貝寶，我似乎無法將產品從購物車發送到貝寶控制器，每個單獨的產品需求按順序發送。MVC PayPal集成

這是我的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); 
     } 
    } 
}

而我的結算視圖，我需要的細節;

@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 + ')'); 
        }); 
      } 
     }); 
    }); 
</script> 
<center> 
    <h3> 
     Review your cart: 
    </h3> 
    <p class="button"> 
     @using (Html.BeginForm("ValidateCommand", "PayPal")) 
      { 
       <input type="submit" name="btnConfirm" value="Check Out with Paypal" /> 
      } 


     @Html.ActionLink((string)ViewBag.CartStatus, (string)ViewBag.Link, (string)ViewBag.Link2) 

     @Html.ActionLink("Continue Shopping ", "Index", "Store") 



</p> 
<div id="update-message"> 
</div> 
<table> 
    <tr> 
     <th> 
      Product Name 
     </th> 
     <th> 
      Price (each) 
     </th> 
     <th> 
      Quantity 
     </th> 
     <th></th> 
    </tr> 
    @foreach (var item in 
       Model.CartItems) 
    { 
     <tr id="[email protected]"> 
      <td> 
       @Html.ActionLink(item.Product.Title, 
"Details", "Store", new { id = item.ProductId }, null) 
      </td> 
      <td> 
       @item.Product.Price 
      </td> 
      <td id="[email protected]"> 
       @item.Count 
      </td> 
      <td> 
       <a href="#" class="RemoveLink" 
        data-id="@item.RecordId"> 
        Remove 
        from cart 
       </a> 
      </td> 
     </tr> 
    } 
    <tr> 
     <td> 
      Total 
     </td> 
     <td></td> 
     <td></td> 
     <td id="cart-total"> 
      @Model.CartTotal 
     </td> 
    </tr> 
</table> 
</center>

而控制器;

namespace T_shirt_Company_v3.Controllers 
{ 
    public class ShoppingCartController : Controller 
    { 
     TshirtStoreDB storeDB = new TshirtStoreDB(); 
     // 
     // GET: /ShoppingCart/ 
     public ActionResult Index() 
     { 

      var cart = ShoppingCart.GetCart(this.HttpContext); 

       // Set up the ViewModel 
       ShoppingCartViewModel viewModel = new ShoppingCartViewModel 
       { 
        CartItems = cart.GetCartItems(), 
        CartTotal = cart.GetTotal() 
       }; 


      if (viewModel.CartItems.Any()) 
      { 
       ViewBag.CartStatus = "Proceed to checkout or "; 
       ViewBag.Link = "AddressAndPayment"; 
       ViewBag.Link2 = "Checkout"; 

      } 
      else 
      { 
       ViewBag.CartStatus = "Cart is empty please "; 
       ViewBag.Link = "Index"; 
       ViewBag.Link2 = "Store"; 
      } 

      // Return the view 
      return View(viewModel); 
     } 


     // 
     // GET: /Store/AddToCart/5(ID) 
     public ActionResult AddToCart(int id) 
     { 
      // Retrieve the Product from the database 
      var addedProduct = storeDB.Products 
       .Single(product => product.ProductId == id); 

      // Add it to the shopping cart 
      var cart = ShoppingCart.GetCart(this.HttpContext); 

      cart.AddToCart(addedProduct); 

      // Go back to the main store page for more shopping 
      return RedirectToAction("Index"); 
     } 
     // 
     // AJAX: /ShoppingCart/RemoveFromCart/5(ID) 
     [HttpPost] 
     public ActionResult RemoveFromCart(int id) 
     { 
      // Remove the item from the cart 
      var cart = ShoppingCart.GetCart(this.HttpContext); 

      // Get the name of the product to display confirmation 
      string productName = storeDB.Carts 
       .Single(item => item.RecordId == id).Product.Title; 

      // Removes item from cart 
      int itemCount = cart.RemoveFromCart(id); 

      // Display the confirmation message saying removed from cart 
      var results = new ShoppingCartRemoveViewModel 
      { 
       Message = Server.HtmlEncode(productName) + 
        " has been removed from your shopping cart.", 
       CartTotal = cart.GetTotal(), 
       CartCount = cart.GetCount(), 
       ItemCount = itemCount, 
       DeleteId = id 
      }; 
      return Json(results); 
     } 
     // 
     // GET: /ShoppingCart/CartSummary 
     [ChildActionOnly] 
     public ActionResult CartSummary() 
     { 
      var cart = ShoppingCart.GetCart(this.HttpContext); 

      ViewData["CartCount"] = cart.GetCount(); 
      return PartialView("CartSummary"); 
     } 


     //test close connection when done 
     protected override void Dispose(bool disposing) 
     { 
      storeDB.Dispose(); 
     } 
    } 
}
