Question

我正在使用并行自适应支付。我从paypal开发者网站的以下链接获得了php编码。

https://www.paypal-labs.com/integrationwizard/adaptive/main.php

我使用IPN监听器如下，

 <?php

// STEP 1: Read POST data

// reading posted data from directly from $_POST causes serialization 
// issues with array data in POST
// reading raw POST data from input stream instead. 
$raw_post_data = file_get_contents('php://input');

    curl_close($ch);
$raw_post_array = explode('&', $raw_post_data);
$from="manikandan.a@quadrantsystems.com";
    $to="manikandan.vkpr@gmail.com";
    $subject="curl_exec".$raw_post_data;
    $headers = "MIME-Version: 1.0\r\n";
    $headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
    $headers .= 'From:'.$from."\r\n";
    @mail($to,$subject,print_r($raw_post_array),$headers);
$myPost = array();
foreach ($raw_post_array as $keyval) {
  $keyval = explode ('=', $keyval);
  if (count($keyval) == 2)
     $myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the post from PayPal system and add 'cmd'
$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");
    $from="manikandan.a@quadrantsystems.com";
    $to="manikandan.vkpr@gmail.com";
    $subject="curl_exec".curl_error($ch);
    $headers = "MIME-Version: 1.0\r\n";
    $headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
    $headers .= 'From:'.$from."\r\n";
    @mail($to,$subject,$Message,$headers);
    curl_close($ch);
    exit;
}
curl_close($ch);


// STEP 3: Inspect IPN validation result and act accordingly

if (strcmp ($res, "VERIFIED") == 0) {
    // 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 payment

    // 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'];


     $from="manikandan.a@quadrantsystems.com";
     $to="manikandan.vkpr@gmail.com";
     $subject='success'.$txn_id."paysts".$payment_status."Currency".$payment_currency."Email".$payer_email;
     $headers = "MIME-Version: 1.0\r\n";
               $headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
               $headers .= 'From:'.$from."\r\n";
               if(@mail($to,$subject,$Message,$headers));

} else if (strcmp ($res, "INVALID") == 0) {
     $from="manikandan.a@quadrantsystems.com";
     $to="manikandan.vkpr@gmail.com";
     $subject='invalid'.$item_name;
     $headers = "MIME-Version: 1.0\r\n";
               $headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
               $headers .= 'From:'.$from."\r\n";
               @mail($to,$subject,$Message,$headers);
    // log for manual investigation

}

?>

第一封邮件和第二封邮件已执行且邮件已收到，但$ _POST值为空。

 $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'];

在验证了以下邮件功能执行但包含空值后。

Answer 1

很可能您没有看到POST值返回并且因为它们如何回来而正确填充到您的脚本中，并且它们未被正确解析。使用自适应Payments时，IPN POST的格式与常规付款略有不同。

交易[0] = .id_for_sender_txn ...＆安培;交易[0]。接收机= paypal_tester_12987336_biz @ paypal.com＆安培;交易[0] = .is_primary_receiver假安培;交易[0] = .ID ...＆安培;交易[0] .STATUS =完成＆安培;交易[0] .status_for_sender_txn =完成＆安培;交易[0] = .amount CAD + 10.00

您需要确保正确解析数据。

无法在付款中获得自适应付款中的交易详情
