我正在尝试为 Clickbank 创建一个 IPN 侦听器，但到目前为止我还没有成功。

我使用了 clickbank 网站上列出的代码示例：https: //support.clickbank.com/entries/22803622-Instant-Notification-Service

    <?php
// NOTE: the mcrypt libraries need to be installed and listed as an available extension in
// your phpinfo() to be able to use this method of decryption.
$secretKey = "YOUR SECRET KEY"; // secret key from your ClickBank account
 // get JSON from raw body...
$message = json_decode(file_get_contents('php://input'));
// Pull out the encrypted notification and the initialization vector for
// AES/CBC/PKCS5Padding decryption
$encrypted = $message->{'notification'};
$iv = $message->{'iv'};
error_log("IV: $iv");
// decrypt the body...
$decrypted = trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_128,
                                 substr(sha1($secretKey), 0, 32),
                                 base64_decode($encrypted),
                                 MCRYPT_MODE_CBC,
                                 base64_decode($iv)), "\0..\32");
error_log("Decrypted: $decrypted");
// convert the decrypted string to a JSON object...
$order = json_decode($decrypted);
// Ready to rock and roll - If the decoding of the JSON string wasn't successful,
// then you can assume the notification wasn't encrypted with your secret key.
?>

对于 ipn v4，我设法为 ipn 测试器获得了经过验证的确认，并将输出保存在我的日志中。但是对于 v6，我什至无法将输出保存到日志文件中。似乎clickbank甚至没有发送任何东西。他们的文档含糊不清，我想知道这段代码是否应该首先工作。

有人有这方面的经验吗？我应该返回响应 200 以外的任何内容吗？

提前致谢。

您可以做几件事，这些事情与我的代码配合得很好。(1) PHP 版本 - 如果您使用的是 PHP 7+，请尝试将其更改为 PHP 5.6 (2) 使用 $HTTP_RAW_POST_DATA 而不是 file_get_contents（我知道 file_get_contents 更好，但在它不起作用时使用替代方法）

这是尝试的代码， $secretKey = "Your Secret Key";

// get JSON from raw body...
//$message = json_decode(file_get_contents('php://input'));

$message = $HTTP_RAW_POST_DATA;
$message = json_decode($message, true);
$messageString = http_build_query($message);    //converts associative array in to string
error_log("message string: $messageString");
$encrypted = $message['notification'];
$iv = $message['iv'];
error_log("IV: $iv");

// decrypt the body...
$decrypted = trim(openssl_decrypt(base64_decode($encrypted),'AES-256-CBC',substr(sha1($secretKey), 0, 32),OPENSSL_RAW_DATA, base64_decode($iv)), "\0..\32");

error_log("Decrypted: $decrypted");

////UTF8 Encoding, remove escape back slashes, and convert the decrypted string to a JSON object...
$sanitizedData = utf8_encode(stripslashes($decrypted));
$jsonDecodeData = json_decode($decrypted, true);
$jsonDecodeDataString = http_build_query($jsonDecodeData);

<?php

function ipnVerification() {
    $secretKey="YOUR SECRET KEY";
    $pop = "";
    $ipnFields = array();
    foreach ($_POST as $key => $value) {
        if ($key == "cverify") {
            continue;
        }
        $ipnFields[] = $key;
    }
    sort($ipnFields);
    foreach ($ipnFields as $field) {
        // if Magic Quotes are enabled $_POST[$field] will need to be
        // un-escaped before being appended to $pop
        $pop = $pop . $_POST[$field] . "|";
    }
    $pop = $pop . $secretKey;
    $calcedVerify = sha1(mb_convert_encoding($pop, "UTF-8"));
    $calcedVerify = strtoupper(substr($calcedVerify,0,8));
    return $calcedVerify == $_POST["cverify"];
}

?>

您可以使用它来验证您的 IPN。它会很好用
