我在沙盒中测试了一切正常,IPN 侦听器会按预期工作,我也会在邮件中得到预期的响应。

我现在已经上线了,虽然客户可以下单购买罚款,而且 PayPal 甚至给出了购买交易 ID,但 IPN 监听器似乎已经停止工作,它从未从 PayPal 听到 IPN,因此没有任何业务逻辑每当进行购买时,应该发生的处理就会触发。怎么了?

我的 IPN 侦听器代码没有任何问题,因为它在沙盒环境中运行良好。我使用了这个 IPN 代码:https ://github.com/Quixotix/PHP-PayPal-IPN

它根本没有受到打击。这就是我使用 NVP 请求的方式:

$return_url = urlencode("http://www.zeej.com.sa/printshop/checkout4_confirm.php");
$cancel_url = urlencode("http://www.zeej.com.sa/printshop/cancel.php");
$notify_url = urlencode("http://www.zeej.com.sa/printshop/ipn.php");
$nvpStr ="&BUTTONCODE=HOSTED&BUTTONTYPE=BUYNOW&L_BUTTONVAR1=amount=".$usd_total."&L_BUTTONVAR2=return=".$return_url."&L_BUTTONVAR3=cancel_return=".$cancel_url."&L_BUTTONVAR4=no_shipping=1&L_BUTTONVAR5=notify_url=".$notify_url."&L_BUTTONVAR6=custom=".$custom_qs;

$httpParsedResponseAr = PPHttpPost('BMCreateButton', $nvpStr);

if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])) {
    $hostedbuttonid = $httpParsedResponseAr["HOSTEDBUTTONID"];
} else  {
    die('Please refresh the page and try again. <br />Error: Create Payment Button Failed: ' . print_r($httpParsedResponseAr, true));
}

这是我的 PPHttpPost 代码,我也是从网上某处获得的,在沙盒测试期间运行良好:

function PPHttpPost($methodName_, $nvpStr_) {
    global $environment;
    $environment = "";

    // Set up your API credentials, PayPal end point, and API version.


    $API_UserName = urlencode('xxxxxxxxxxxxxxxxxxxxxxxxxxx'); 
    $API_Password = urlencode('xxxxxxxxxxxxxxxxxxxxxxxxxxx');
    $API_Signature = urlencode('xxxxxxxxxxxxxxxxxxxxxxxxxx'); 

    $API_Endpoint = "https://api-3t.paypal.com/nvp"; // 
    if("sandbox" === $environment || "beta-sandbox" === $environment) {
        $API_Endpoint = "https://api-3t.$environment.paypal.com/nvp"; 
    }
    $version = urlencode('98.0');

    // Set the curl parameters.
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $API_Endpoint);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);

    // Turn off the server and peer verification (TrustManager Concept).
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);

    // Set the API operation, version, and API signature in the request.
    $nvpreq = "METHOD=$methodName_&VERSION=$version&PWD=$API_Password&USER=$API_UserName&SIGNATURE=$API_Signature".$nvpStr_;

    //echo($nvpreq);

    // Set the request as a POST FIELD for curl.
    curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);

    // Get response from the server.
    $httpResponse = curl_exec($ch);

    if(!$httpResponse) {
        exit("$methodName_ failed: ".curl_error($ch).'('.curl_errno($ch).')');
    }

    // Extract the response details.
    $httpResponseAr = explode("&", $httpResponse);

    $httpParsedResponseAr = array();
    foreach ($httpResponseAr as $i => $value) {
        $tmpAr = explode("=", $value);
        if(sizeof($tmpAr) > 1) {
            $httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1];
        }
    }

    if((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) {
        exit("Invalid HTTP Response for POST request($nvpreq) to $API_Endpoint.");
    }

    return $httpParsedResponseAr;
}

好的,我发现了问题。用paypal没问题。我去了我的 IPN 页面www.mydomain.com/printshop/ipn.php,PHP 向我显示页面上有语法错误......所以这就是它不接受任何 IPN 命中的原因,因为它甚至没有运行!修复了语法错误,现在我收到了 IPN 命中。

您是否检查过您的服务器访问日志和错误日志以确保脚本没有出错?现在有一些 IPN 问题正在发生,这可能会导致您看到的 yoru 问题。我建议向PayPal 的商家技术支持开一张票,以便调查此问题。这样,一旦问题得到解决,您也会收到通知。
