Question

我将Simulator的Paypal IPN发送到外部主机上的PHP脚本。我的脚本代码如下：

<?php
    error_reporting(-1);
    ini_set('display_errors', 'On');

// STEP 1: read POST data

// Reading POSTed data directly from $_POST causes serialization issues with array data in the POST.
// Instead, read raw POST data from the input stream. 
$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

$ch = curl_init('https://www.paypal.com/cgi-bin/webscr');
curl_setopt($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_name1'];
    $item_number = $_POST['item_number1'];
    $payment_status = $_POST['payment_status'];
    $payment_amount = $_POST['mc_gross1'];
    $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>";
    }

    // connect to db
    mysql_connect('HOST','USER','PASS');
    mysql_select_db('DBNAME');

    // query
    mysql_query("INSERT INTO ipnlogs (item_name) VALUES ('$item_name')");
} else if (strcmp ($res, "INVALID") == 0) {
    // IPN invalid, log for manual investigation
    echo "The response from IPN was: <b>" .$res ."</b>";
}
/*mysql_connect('HOST','USER','PASS');
$result = mysql_query('SHOW TABLES FROM DBNAME ');
while ($row = mysql_fetch_row($result)) {
    echo "Table: {$row[0]}\n";
}*/
?>

连接数据库没有问题，然后数据库表存在并成功插入测试查询 - INSERT INTO ipnlogs (item_name) VALUES ('test item')。

我还要注意，最后注释掉的代码已成功打印Table: ipnlogs \n

对于那些犯同样愚蠢错误的人，我会保留这个问题 - 如果您正在使用沙盒模拟器进行测试，那么您应该发回Paypal进行验证的URL应该是不同的：

对于直播IPN： $ch = curl_init('https://www.paypal.com/cgi-bin/webscr');

用于IPN模拟器 $ch = curl_init('https://www.sandbox.paypal.com/cgi-bin/webscr');

Paypal IPN脚本不插入数据库
