fsockopen non supportata dal mio host + paypal ipn

[Vincent]

Salve a tutti, vorrei sapere una cosa. Sto implementando un ipn per i pagamenti su PayPal.
La struttura del mio codice è la seguente:

// Revision Notes
// 11/04/11 - changed post back url from [url]https://www.paypal.com/cgi-bin/webscr[/url] to [url]https://ipnpb.paypal.com/cgi-bin/webscr[/url]
// For more info see below:
// [url]https://www.x.com/content/bulletin-ip-address-expansion-paypal-services[/url]
// "ACTION REQUIRED: if you are using IPN (Instant Payment Notification) for Order Management and your IPN listener script is behind a firewall that uses ACL (Access Control List) rules which restrict outbound traffic to a limited number of IP addresses, then you may need to do one of the following: 
// To continue posting back to [url]https://www.paypal.com[/url]  to perform IPN validation you will need to update your firewall ACL to allow outbound access to *any* IP address for the servers that host your IPN script
// OR Alternatively, you will need to modify  your IPN script to post back IPNs to the newly created URL [url]https://ipnpb.paypal.com[/url] using HTTPS (port 443) and update firewall ACL rules to allow outbound access to the ipnpb.paypal.com IP ranges (see end of message)."


// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

foreach ($_POST as $key => $value) {
    $value = urlencode(stripslashes($value));
    $req .= "&$key=$value";
}

// post back to PayPal system to validate
$header = "POST /cgi-bin/webscr HTTP/1.0\r\n"; 
// If testing on Sandbox use: 
$header .= "Host: [url]www.sandbox.paypal.com:443\r\n[/url]";
//$header .= "Host: ipnpb.paypal.com:443\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

// If testing on Sandbox use:
$fp = @fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
//$fp = fsockopen ('ssl://ipnpb.paypal.com', 443, $errno, $errstr, 30);

// 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'];

if (!$fp) {
    // HTTP ERROR
    $var=fopen("./error.log","a+");
    fwrite($var, $errno." ".$errstr);
    fclose($var);
} else {
    fputs ($fp, $header . $req);
    while (!feof($fp)) {
        $res = fgets ($fp, 1024);
        if (strcmp ($res, "VERIFIED") == 0) {
            // check 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
            
            $mail_From = "From: [email]ordini@mysite.it[/email]";
            $mail_To = "ordini@mysite.it";
            $mail_Subject = "VERIFIED IPN";
            $mail_Body = $req;
            
            foreach ($_POST as $key => $value){
                $emailtext .= $key . " = " .$value ."\n\n";
            }
    
            mail($mail_To, $mail_Subject, $emailtext . "\n\n" . $mail_Body, $mail_From);

        }
        else if (strcmp ($res, "INVALID") == 0) {
            // log for manual investigation

            $mail_From = "From: [email]ordini@mysite.it[/email]";
            $mail_To = "ordini@mysite.it";
            $mail_Subject = "INVALID IPN";
            $mail_Body = $req;

            foreach ($_POST as $key => $value){
                $emailtext .= $key . " = " .$value ."\n\n";
            }

            mail($mail_To, $mail_Subject, $emailtext . "\n\n" . $mail_Body, $mail_From);

        }
    }
    
    fclose ($fp);
} 

Quando arriva una notifica di pagamento viene scritto sul file error.log questo: 110 Connection timed out

Ho aperto un ticket all'host il quale mi dice che la funzione non è supportata per motivi di sicurezza. Esiste un modo per ovviare a questo spiacevole inconveniente, oppure devo cambiare host?

Ciao,
credo di avere lo stesso problema.

Il mio sito è ospitato da Aruba che non consente connessioni ssl.

Quindi la notifica istantanea IPN di paypal non può essere verificata in nessun modo (fino a qualche mese fa almeno la sandbox funzionava adesso nemmeno quella).

Rinnovo la richiesta.

Qualcuno sa come riuscire a risolvere il problema?

cambia hosting

[stranet]

infatti ci stavo pensando seriamente.

Consigli?
qualcosa che mi consenta di utilizzare ssl, cURL?

Prova a spulciare questa lista http://hosting.html.it/cerca/find.php?key=php

per i servizi però devi vedere hosting per hosting
