我查看了谷歌和本网站上的所有答案 - 没有人帮助过。

我的代码包含标准的IPN侦听器代码：

$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]);
}
// read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) {
   $get_magic_quotes_exists = true;
} 
foreach ($myPost as $key => $value) {        
   if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) { 
        $value = urlencode(stripslashes($value)); 
   } else {
        $value = urlencode($value);
   }
   $req .= "&$key=$value";
}

// STEP 2: POST IPN data back to PayPal to validate
$ch = curl_init('https://www.sandbox.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
// In wamp-like environments that do not come bundled with root authority certificates,
// please download 'cacert.pem' from "http://curl.haxx.se/docs/caextract.html" and set 
// the directory path of the certificate as shown below:
// curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem');
if( !($res = curl_exec($ch)) ) {
    // error_log("Got " . curl_error($ch) . " when processing IPN data");
    curl_close($ch);
    exit;
}
curl_close($ch);

// STEP 3: Inspect IPN validation result and act accordingly
if (strcmp ($res, "VERIFIED") == 0) {
    // The IPN is verified, process it:
    // check whether the payment_status is Completed
    // check that txn_id has not been previously processed
    // check that receiver_email is your Primary PayPal email
    // check that payment_amount/payment_currency are correct
    // process the notification
    // assign posted variables to local variables
    $item_name = $_POST['item_name'];
    $item_number = $_POST['item_number'];
    $payment_status = $_POST['payment_status'];
    $payment_amount = $_POST['mc_gross'];
    $payment_currency = $_POST['mc_currency'];
    $txn_id = $_POST['txn_id'];
    $receiver_email = $_POST['receiver_email'];
    $payer_email = $_POST['payer_email'];
    // IPN message values depend upon the type of notification sent.
    // To loop through the &_POST array and print the NV pairs to the screen:
    foreach($_POST as $key => $value) {
      echo $key." = ". $value."<br>";
    }
} else if (strcmp ($res, "INVALID") == 0) {
    // IPN invalid, log for manual investigation
    echo "The response from IPN was: <b>" .$res ."</b>";
}
?>

我确保使用的网址是沙箱，而非生产。我通过PayPal上的IPN模拟器发送IPN，它说Successfully sent, and handshake verified.这意味着我的听众回应成功。但是，当我实际访问/ipn.php时，它只是说UNVERIFIED，并且不会接收从paypal发送的任何POST数据。我现在通过首先发送IPN来测试这个，然后刷新我的/ipn.php以查看它是否拾取了POST数据，但它没有。我错过了什么？请询问任何其他细节。

来自PayPal的POST数据位于$raw_post_data变量中。如果你不对它做任何事情（比如存储在数据库，平面文件等），那就简单地列出如果您希望在执行GET /ipn.php HTTP请求时看到IPN验证结果（这是您的浏览器在浏览器中提取ipn.php时所执行的操作），则需要添加返回最新的逻辑IPN验证状态。

这可能不是你想要的。
相反，单步执行PayPal提供的示例脚本并查看if (strcmp ($res, "VERIFIED") == 0) {：这允许您做什么，添加逻辑，例如，将结果写入文件。或者将其存储在数据库中并将订单状态翻转为“已付款”。

为什么我的IPN侦听器没有收到从我的paypal沙箱发送的数据？
