Question

我的PayPal IPN代码在购买完成后接收从PayPal发回的发布数据，但不会将数据插入数据库。如果代码无法将数据插入数据库，我的代码会向我发送电子邮件。如果我把这个帖子数据并在ipn.php后粘贴到地址栏中，它就能完美运行。我究竟做错了什么？我是否必须将数据发回PayPal？

我的IPN听众

    <?php
include 'includes/class.user.php';
$user = new USER();
$emailtext = "";

$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
    $keyval = explode ('=', $keyval);
    if (count($keyval) == 2)
        $myPost[$keyval[0]] = urldecode($keyval[1]);
}

$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) {
    $get_magic_quotes_exists = true;
}
foreach ($myPost as $key => $value) {
    $value = urlencode($value);
    $req .= "&$key=$value";
}

$paypalURL = "https://ipnpb.paypal.com/cgi-bin/webscr";

我已确认PayPal的帖子将帖子与PayPal匹配，但我仍然收到INVALID响应，并且没有数据插入到数据库中。如果我从PayPal的初始POST获取原始发布数据字符串并将其粘贴到地址栏中，它就可以很好地插入到数据库中。我无法弄清楚为什么它不会自己将数据插入数据库。我在PayPal上的IPN历史记录显示500的html响应及其重试。

Answer 1

如果您回发的IPN消息与发送给您的一个PayPal不完全匹配，则将发生INVALID状态。您可以仔细检查您回发的IPN消息中是否有乱码，例如非英文字符。但如果您仍然无法找到根本原因，则必须通过https://www.paypal-techsupport.com/app/ask/联系PayPal技术支持，并提供PayPal交易ID以便进一步检查。

沙盒上存在完全相同的问题。

通过关闭帐户配置文件设置中的“否定测试”并从ipn模拟器中删除日期来实现它。

这个简单的代码使其有效

$ipn_post_data = $_POST;
// Choose url
if (array_key_exists('test_ipn', $ipn_post_data) && 1 === (int) $ipn_post_data['test_ipn']){
    $url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';
}else{
    $url = 'https://www.paypal.com/cgi-bin/webscr';
}
    // Set up request to PayPal
$request = curl_init();
curl_setopt_array($request, array
    (
    CURLOPT_URL => $url,
    CURLOPT_POST => TRUE,
    CURLOPT_POSTFIELDS => http_build_query(array('cmd' => '_notify-validate') + $ipn_post_data),
    CURLOPT_RETURNTRANSFER => TRUE,
    CURLOPT_HEADER => FALSE,
));

    // Execute request and get response and status code
$response = curl_exec($request);
$status = curl_getinfo($request, CURLINFO_HTTP_CODE);

// Close connection
curl_close($request);

if ($status == 200 && $response == 'VERIFIED') {
    $today = date("Y_m_d");
    $file = fopen("LogIPN.$today.txt", "ab");
    $hour = date("H:i:s T");
    fwrite($file, "Verified\r\n");
} else {
    $today = date("Y_m_d");
    $file = fopen("LogIPN.$today.txt", "ab");
    $hour = date("H:i:s T");
    fwrite($file, $response."\r\n");
    fwrite($file, $status."\r\n");
}

出于多种原因，我绝不会在生产中使用该代码。

希望这可以让你感到轻松。
