Php paypal express checkout具有订单id和订单密钥的返回url是什么？

这是我在使用吴商业结帐选项。付款后，我想返回的url有订单id和订单键。 我的问题是，它只返回，没有订单id和订单密钥。 我的问题有什么解决办法吗？？ 当前我得到的返回url是=>example.com/checkout/order received/？token=4688991269822。 但我希望这样=>example.com/checkout/order received/orderid/？key=wc\u order\u 593bc1dcb4324 因为如果我选择另一个支付网关而不是我的自定义支付网关。当我单击下订单时，该订单将使用此类型的url=>
在此url中，它会自动传递这些订单id值和订单密钥。 因此，我如何在expresscheckout.php中获得这种类型的url作为返回url valiable。 请帮忙，谢谢

这是expresscheckout.php

 require_once ("paypalfunction.php");

$resArray = CallShortcutExpressCheckout ($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;
}

您需要订单ID和订单密钥做什么？用于完成订单流程。因为我想通过paypal reccurring方法创建自定义支付网关。例如，当我们点击下订单按钮时，它会使用url（example.com/checkout/order received/7293/？key=wc\u order\u 593bc1dcb4324）完成订单流程，如下所示。在此url中，订单id和订单密钥自动添加到url中。
