购物车上的 PayPal 快速结帐

Question

我希望达到：

所以在我的购物车页面中我设置了session("Payment_Amount") = total 并下载了向导告诉我的两个 asp 文件。 expresschecout.asp 和 paypalfunctions.asp。并将 API 凭据添加到正确的位置。 我从他们的向导中添加了表单：

<form action='expresscheckout.asp' METHOD='POST'>
<input type='image' name='submit' src='https://www.paypal.com/en_US/i/btn/btn_xpressCheckout.gif' border='0' align='top' alt='Check out with PayPal'/>
</form>

但是当我进入我的购物车并按下 paypal 提交按钮时，我被带到 expressheckout.asp 但页面保持不变，在状态栏中显示完成。我该如何调试呢？ ：/

编辑添加了我的代码，ASP：

<!-- #include file ="paypalfunctions.asp" -->
<%

' The paymentAmount is the total value of

'-------------------------------------------------
Set resArray = CallShortcutExpressCheckout (paymentAmount, currencyCodeType, paymentType, returnURL, cancelURL)

ack = UCase(resArray("ACK"))
If ack="SUCCESS" Then
    ' Redirect to paypal.com
    ReDirectURL( resArray("TOKEN") )
Else  
    'Display a user friendly Error on the page using any of the following error information returned by PayPal
    ErrorCode = URLDecode( resArray("L_ERRORCODE0"))
    ErrorShortMsg = URLDecode( resArray("L_SHORTMESSAGE0"))
    ErrorLongMsg = URLDecode( resArray("L_LONGMESSAGE0"))
    ErrorSeverityCode = URLDecode( resArray("L_SEVERITYCODE0"))
End If
%>

我猜我从底部得到了一个错误，但找不到在哪里看到 thm..

有点不清楚您遇到的具体问题是什么，但这里是您需要完成的一系列事件才能使用 PayPal 快速结帐付款方式。这一系列事件的上下文将是您的购物车或您的快速结帐按钮所在的任何页面。

• 创建 ExpressCheckOut 类的实例

• 设置ExpressCheckOut类的A​​piSignature、UserName、Password、Environment、APIVersion、OrderAmount、OrderItemDetails、CancelUrl、ReturnUrl。

• 调用 ExpressCheckout 并获得 ExpressCheckoutResponse。

• 检查 ExpressCheckoutResponse 对象是否成功。

• 如果成功，则使用您从 ExpressCheckoutResponse 对象收到的令牌将用户重定向到正确的 PayPal 端点。

希望这能让您清楚地了解如何正确使用此 PayPal api。

享受吧！
