Question

我在ASP.net中使用PayPal，当我在沙盒中测试时，一切都是正确的，但是当我使用实时部分时，我收到此错误：

此付款无法完成，您的帐户尚未收费。请联系您的商家了解更多信息。我们目前无法使用您的PayPal帐户处理您的付款。请返回商家网站，尝试使用其他付款方式（如果有）。

这是我的webconfig

 <add key="token" value="*************************"/>
  <add key="paypalemail" value="*************@gmail.com"/>
  <add key="PayPalSubmitUrl" value="https://www.paypal.com/cgi-bin/webscr"/>
  <add key="FailedURL" value="http://www.stockholmsbygg.net/Failed.aspx"/>
  <add key="SuccessURL" value="http://www.stockholmsbygg.net/FindOpenRequests.aspx"/>
  <add key="Notification" value="http://www.stockholmsbygg.net/Notification.aspx"/>

并重定向到Paypal

   public static string RedirectToPaypal(string invoiceNumber, string requestId, string userId, string customId, string itemName, string amount)
        {

            string redirecturl = "";
            redirecturl += "https://www.paypal.com/cgi-bin/webscr?cmd=_xclick&business=" + ConfigurationManager.AppSettings["paypalemail"].ToString();
            redirecturl += "&first_name=" + userId;
            redirecturl += "&item_name=" + itemName;
            redirecturl += "&amount=5.00";
            redirecturl += "&quantity=1";
            redirecturl += "&currency=SEK";
            redirecturl += "&invoice=" + invoiceNumber;
            redirecturl += "&custom=" + requestId;
            redirecturl += "&on0=" + HttpContext.Current.Request.UserHostAddress;
            redirecturl += "&return=" + ConfigurationManager.AppSettings["SuccessURL"].ToString() + "?Type=ShowDetail";
            redirecturl += "&cancel_return=" + ConfigurationManager.AppSettings["FailedURL"].ToString();
            redirecturl += "&notify_url=" + ConfigurationManager.AppSettings["Notification"].ToString();
            return redirecturl;
        }

这是我从paypal返回到我的地址后检查的所有内容

if (Request.QueryString["cm"] != null)
                        {

                             const string authToken = "*********************************";

                           string strResponse = streamIn.ReadToEnd();

                                 }

                                 {
                                     // Log for manual investigation
                                     Response.Write("Unable to retrive transaction detail");
                                 }
                             }
                             else
                             {
                                //unknown error
                                 Response.Write("ERROR");
                             }
                         }

有什么问题？也是在第一次测试我付钱但没有发生任何事情。发票状态仍然是假的，因为我付款后它应该变为真！

Answer 1

此功能是100％RedirectToPaypal()

的错误

Paypal没有重定向。该地址只有post个帖子参数，而不是get（重定向）。

这是合乎逻辑的，因为如果你将所有敏感数据放在url上，那么暴露给中间以太网代理的任何人都会保留url所有数据。

对我来说，如果您使用该数据进行重定向，而不是发布，则找不到PayPal账户的任何内容，因为没有发布数据，这就是您收到该错误的原因。
