PayPal Express Checkout无法使用php

Question

我正在尝试使用PHP进行PayPal Express Checkout。

    <form action='/paypal/expresscheckout.php' 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>

这是重定向到paypal屏幕之前的按钮。

<?php

require_once ("paypalfunctions.php");
// ==================================
// PayPal Express Checkout Module
// ==================================

//'------------------------------------
//' The paymentAmount is the total value of 
//' the shopping cart, that was set 
//' earlier in a session variable 
//' by the shopping cart page
//'------------------------------------
//$paymentAmount = $_SESSION["Payment_Amount"];
$paymentAmount = '1';

//'------------------------------------
//' The currencyCodeType and paymentType 
//' are set to the selections made on the Integration Assistant 
//'------------------------------------
$currencyCodeType = "USD";
$paymentType = "Sale";

//'------------------------------------
//' The returnURL is the location where buyers return to when a
//' payment has been succesfully authorized.
//'
//' This is set to the value entered on the Integration Assistant 
//'------------------------------------
$returnURL = "http://www.mydomain.com/add_funds/order_confirm";

//'------------------------------------
//' The cancelURL is the location buyers are sent to when they hit the
//' cancel button during authorization of payment during the PayPal flow
//'
//' This is set to the value entered on the Integration Assistant 
//'------------------------------------
$cancelURL = "http://www.mydomain.com/add_funds/order_cancel";

//'------------------------------------
//' Calls the SetExpressCheckout API call
//'
//' The CallShortcutExpressCheckout function is defined in the file PayPalFunctions.php,
//' it is included at the top of this file.
//'-------------------------------------------------
$resArray = CallShortcutExpressCheckout ($paymentAmount, $currencyCodeType, $paymentType, $returnURL, $cancelURL);
$ack = strtoupper($resArray["ACK"]);
if($ack=="SUCCESS" || $ack=="SUCCESSWITHWARNING")
{
    RedirectToPayPal ( $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"]);

    echo "SetExpressCheckout API call failed. ";
    echo "Detailed Error Message: " . $ErrorLongMsg;
    echo "Short Error Message: " . $ErrorShortMsg;
    echo "Error Code: " . $ErrorCode;
    echo "Error Severity Code: " . $ErrorSeverityCode;
}
?>

这是表达expresscheckout.php代码

点击paypal按钮后，我可以看到此屏幕，没有任何订单信息。

我花了1美元来支付代码，但是在订单摘要中没有说什么。

无论如何，我使用不同的PayPal帐户来进行此交易。

我可以看到我的送货地址和个人信息。

但是，它仍然没有订单摘要信息。

应该说你会得到这个产品，这是1美元。

如果我点击“继续”按钮，它会将页面重定向到“returnURL”

你知道这是什么问题吗？

Answer 1

而不是重定向到https://www.paypal.com/cgi-bin/webcsr?cmd=_express-checkout&token=EC-xxxxxx，而是重定向到https://www.paypal.com/cgi-bin/webcsr?cmd=_express-checkout&token=EC-xxxxxx&useraction=commit

这会将美元价值添加到“订单摘要”部分，并将最终评论页面上的“继续”按钮更改为“立即付款”。
如果您不想要后者，则需要开始发送行项目详细信息;

感谢发帖，它帮助我解决了同样的问题，虽然我稍微改了一下，但我用了它：

https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token= $令牌安培; useraction =提交
