Php paypal链接支付ipn未返回通知

我使用以下代码进行PayPal链接支付

require_once ("paypalplatform.php");
$amount=100;
$amt1=($amount * 10 )/100;
$amt2=$amount-$amt1;

$actionType         = "PAY";
$cancelUrl          = "http://test.com/test";

$returnUrl          = "http://test.com/test";
$currencyCode               = "USD";

$receiverEmailArray = array(
        'a***********_per@gmail.com',
        'a***********_biz@gmail.com'
        );

$receiverAmountArray = array(
        $amt1,
        $amt2
        );

$receiverPrimaryArray = array();

$receiverInvoiceIdArray = array(
        '1',
        '2'
        );

$senderEmail                    = "a************_per@gmail.com";        
$feesPayer                  = "";
$ipnNotificationUrl             = "http://test.com/paypal/buynow.php";
$memo                       = "";       
$pin                        = "agalameex";      
$preapprovalKey                 = "";       
$reverseAllParallelPaymentsOnError          = "";   
$trackingId                 = generateTrackingID();
$resArray = CallPay ($actionType, $cancelUrl, $returnUrl, $currencyCode, $receiverEmailArray,
                        $receiverAmountArray, $receiverPrimaryArray, $receiverInvoiceIdArray,
                        $feesPayer, $ipnNotificationUrl, $memo, $pin, $preapprovalKey,
                        $reverseAllParallelPaymentsOnError, $senderEmail, $trackingId
);

$ack = strtoupper($resArray["responseEnvelope.ack"]);
if($ack=="SUCCESS")
{
    if ("" == $preapprovalKey)
    {
        // redirect for web approval flow
        $cmd = "cmd=_ap-payment&paykey=" . urldecode($resArray["payKey"]);
        RedirectToPayPal ( $cmd );
    }
    else
    {
        // payKey is the key that you can use to identify the result from this Pay call
        $payKey = urldecode($resArray["payKey"]);
        // paymentExecStatus is the status of the payment
        $paymentExecStatus = urldecode($resArray["paymentExecStatus"]);
    }
} 
else  
{
    //Display a user friendly Error on the page using any of the following error information returned by PayPal
    //TODO - There can be more than 1 error, so check for "error(1).errorId", then "error(2).errorId", and so on until you find no more errors.
    $ErrorCode = urldecode($resArray["error(0).errorId"]);
    $ErrorMsg = urldecode($resArray["error(0).message"]);
    $ErrorDomain = urldecode($resArray["error(0).domain"]);
    $ErrorSeverity = urldecode($resArray["error(0).severity"]);
    $ErrorCategory = urldecode($resArray["error(0).category"]);

echo "Preapproval API call failed. ";
echo "Detailed Error Message: " . $ErrorMsg;
echo "Error Code: " . $ErrorCode;
echo "Error Severity: " . $ErrorSeverity;
echo "Error Domain: " . $ErrorDomain;
echo "Error Category: " . $ErrorCategory;

}

在上面的代码中，除了返回通知（$ipnNotificationUrl）之外，其他一切都正常工作。付款完成后，我没有从$ipnNotificationUrl收到任何通知。有人能帮我吗？

调试提示：在PayPal后端检查IPN配置。用一个简单的脚本替换您的脚本，该脚本只显示调用它的时间和输入内容。

在PayPal中检查您的IPN历史记录。如果它显示的不是200响应代码，那么您就知道IPN侦听器有问题

您可以检查web服务器日志，以查看在命中脚本时发生的错误

或者，您可以设置一个简单的HTML表单，其中包含与您期望从PayPal获得的内容相匹配的隐藏字段。然后你可以在浏览器中提交，这样你就可以在屏幕上看到结果

请记住，以这种方式进行测试将导致PayPal返回无效响应，因为IPN数据不是来自他们的服务器，但您可以根据测试目的进行相应调整，解决问题，然后您就可以继续了。
