Paypal集成问题 - 将响应视为失败 [英] Paypal integration issue- Getting response as failure

问题描述

您好我正在尝试将paypal集成到我的asp.net应用程序。我是这种支付网关的新手。但是，我创建了Sandbox帐户，沙箱中的所有东西都运行良好。



我将所需的值发送到sandbox.paypal.com并且有牵引力没关系。

但是，当我回到我的应用程序并且使用PDT响应方式时，我得到失败响应。

我没有得到transaaction id（tx）来自paypal。



任何人都可以知道过来这个问题。



提前致谢........



我使用以下代码



发送给paypal的值链接

hi i am trying to integrate paypal to my asp.net application .I am new to this type of payment gateways. But, i had created the Sandbox accounts and every thing in sandbox is working fine.

I am sending the required values to the sandbox.paypal.com and there the traction is ok.
But , i am getting failure response when it come backs to my application and i am using PDT way of response .
and i am not getting the transaaction id (tx) from paypal.

Can anyone have an idea of over coming this issue.

Thanks in advance.........

I am using the following code

Values sent to paypal link

string redirectUrl = "";


                redirectUrl += "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_xclick&business=" + ConfigurationManager.AppSettings["PayPalEmail"].ToString();


                redirectUrl += "&first_name" + CommonHelper.FirstName;
                redirectUrl += "&item_name= Credits";
                redirectUrl += "&amount=" + lblPrice.Text;
                redirectUrl += "&currency_code=GBP";
                //redirectUrl += "&tax=" + lblVatPRice.Text;
                redirectUrl += "&quantity=1";

                redirectUrl += "&return=" + ConfigurationManager.AppSettings["SuccessURL"].ToString();
                redirectUrl += "&cancel_return=" + ConfigurationManager.AppSettings["FailedURL"].ToString();
                //redirectUrl += "&notify_url=" + ConfigurationManager.AppSettings["NotifyURL"].ToString();
                Response.Redirect(redirectUrl);

推荐答案

永远不要接受来自不安全网站的代码来处理任何事情用真钱做的。

你不知道是谁给你代码，你不知道它做了什么，你不知道它把钱正确地放到了适当的账户里，没有通过细节到任何第三个p arties。



只能从Paypal自己获取此类代码 - 否则欺诈的范围太大。请记住，如果您的行为被视为疏忽，您本人可能要对任何损失承担责任 - 从公共论坛获取您的代码肯定会是！

Never, ever, accept code from a insecure website to handle anything to do with real money.
You do not know who is giving you the code, you do not know what it does, you do not know that it places the monies correctly into the appropriate account, without passing the details to any third parties.

Only get such code from Paypal themselves - the scope for fraud otherwise is far too large. And remember, you personally could be liable for any monies lost if your action is seen to be negligent - which getting your code from a public forum would most certainly be!
