嗨,我知道這是一個noob問題,但我無法找到任何文檔,我想在同一交易中支付一個或多個項目,但是我得到了這個錯誤:使用PayPal REST API一次支付多個項目ASP.NET MVC
Exception in HttpConnection Execute: Invalid HTTP response The remote server returned an error: (400) Bad Request.
IM硬編碼的項目列表的一部分,但我不understan beetween Amount.Total的差異,我的所有項目的價格*數量的價格
public ActionResult CreatePayment(string description, decimal price, decimal tax = 0, decimal shipping = 0)
{
var viewData = new PayPalViewData();
var guid = Guid.NewGuid().ToString();
var paymentInit = new Payment
{
intent = "authorize",
payer = new Payer
{
payment_method = "paypal"
},
transactions = new List<Transaction>
{
new Transaction
{
item_list = new ItemList{
items = new List<Item>{
new Item{
name = "item 1",
currency = "USD",
price = "20",
quantity = "2"
},
new Item{
name = "item 2",
currency = "USD",
price = "40",
quantity = "1"
},
new Item{
name = "item 3",
currency = "USD",
price = "40",
quantity = "1"
}
}
},
amount = new Amount
{
currency = "EUR",
total = (price + tax + shipping).ToString(),
details = new Details
{
subtotal = price.ToString(),
tax = tax.ToString(),
shipping = shipping.ToString()
}
},
description = description
},
},
redirect_urls = new RedirectUrls
{
return_url = Utilities.ToAbsoluteUrl(HttpContext, String.Format("~/paypal/confirmed?id={0}", guid)),
cancel_url = Utilities.ToAbsoluteUrl(HttpContext, String.Format("~/paypal/canceled?id={0}", guid)),
},
};
viewData.JsonRequest = JObject.Parse(paymentInit.ConvertToJson()).ToString(Formatting.Indented);
try
{
var accessToken = new OAuthTokenCredential(ConfigManager.Instance.GetProperties()["ClientID"], ConfigManager.Instance.GetProperties()["ClientSecret"]).GetAccessToken();
var apiContext = new APIContext(accessToken);
var createdPayment = paymentInit.Create(apiContext);
var approvalUrl = createdPayment.links.ToArray().FirstOrDefault(f => f.rel.Contains("approval_url"));
if (approvalUrl != null)
{
Session.Add(guid, createdPayment.id);
return Redirect(approvalUrl.href);
}
viewData.JsonResponse = JObject.Parse(createdPayment.ConvertToJson()).ToString(Formatting.Indented);
return View("Error", viewData);
}
catch (PayPalException ex)
{
viewData.ErrorMessage = ex.Message;
return View("Error", viewData);
}
}
如果我刪除項目清單,它的工作原理,但只是在 中描述的1項目我能做什麼?你有這個指導嗎?貝寶的GUID和演示是一個項目只

謝謝但我不想在視圖中執行此操作,而PayPal鏈接是針對經典api的,即時通訊使用Rest api並且它沒有示例代碼只是商家和其他信息的費用 –
