Question

我最近建立了一个Amazon AWS免费套餐帐户。我有一个实例运行，apache，php5，cURL等安装，一切似乎工作正常，直到这一点。我在服务器上运行了一个Paypal IPJ脚本，如下所示：

<?php

error_reporting(E_ALL);

class PaypalIPN {

    private $_url;

    /**
    * @param $mode String
    * Set to live when applicable
    */
    public function __construct($mode = 'sandbox'){
        if($mode == 'live')
            $this->_url = 'https://paypal.com/cgi-bin/webscr';
        else
            $this->_url = "https://sandbox.paypal.com/cgi-bin/webscr";
    }

    /**
    * @param
    * cURL function that will get info from paypal
    */
    public function run(){
        # Post fields
        $fields = 'cmd=_notify-validate';

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

        $ch = curl_init();
            curl_setopt_array($ch, array(
                CURLOPT_URL             => $this->_url,
                CURLOPT_SSL_VERIFYPEER  => false,
                CURLOPT_RETURNTRANSFER  => true,
                CURLOPT_POST            => true,
                CURLOPT_POSTFIELDS      => $fields
            ));
        $result = curl_exec($ch);
        echo $result;
        echo '<br>';
        echo 'Result^';
        curl_close($ch);
        $a = strcmp($result, "VERIFIED") == 0;
        # Write to file here, so we can analyze
        $fh = fopen('result.txt', 'w');
        fwrite($fh, $result . ' --' . $fields . ' --' . $a);
        fclose($fh);

        if (strcmp ($result, "VERIFIED") == 0){
              # If the transaction has been verfied
              # Continue...

              // payment info
              $payment_status = $_POST['payment_status'];
              $payment_amount = $_POST['mc_gross'];
              $payment_currency = $_POST['mc_currency'];
              $txn_id = $_POST['txn_id'];

              // product info
              $item_name = $_POST['item_name'];
              $item_number = $_POST['item_number'];

              // buyer info
              $payer_email = $_POST['payer_email'];
              $first_name = $_POST['first_name'];
              $last_name = $_POST['last_name'];
              $address_city = $_POST['address_city'];
              $address_state = $_POST['address_state'];
              $address_country = $_POST['address_country'];

              // receiver_email, that's our email address
              $receiver_email = $_POST['receiver_email'];

              // put your actual email address here
              $our_email = 'email@email.com';

              if (($payment_status == 'Completed') &&
                 ($receiver_email == $our_email) &&
                 ($payment_amount == "20.00" ) &&
                 ($payment_currency == "USD"))
              {
                foreach ($_POST as $key => $value)
                {
                  $emailtext .= $key . " = " .$value ."\n\n";
                }
                # If all is good, mail our customer, and create a tmp/.dat file
                # to be created for our license

                mail($payer_email, "Live-VERIFIED IPN", $emailtext . "\n\n" . $req);

                $dat_filename = $first_name . '-' . $last_name . '-' . $address_city . '.dat';

                $fc = fopen($dat_filename, 'w');
                fwrite($fc, 
                    "first_name = " . $first_name . "\n\n" .
                    "last_name = "  . $last_name . "\n\n" .
                    "email = " . $receiver_email . "\n\n" .
                    "city = " . $address_city . "\n\n" .
                    "state = " . $address_state . "\n\n" .
                    "country = " . $address_country
                );
                fclose($fc);

                $filename = explode('.', $dat_filename);

                # Execute shell through PHP
                $wat = "/var/www/license/";
                $argc[0] = $filename[0];
                $out = exec('sudo java -jar license2.jar '.$wat. ' '.$filename[0]);

                $fd = fopen('log.txt', 'w');
                fwrite($fd, $out);
                fclose($fd);
              }
        } else if (strcmp ($result, "INVALID") == 0) {
            {
              // If 'INVALID', send an email. TODO: Log for manual investigation.
              foreach ($_POST as $key => $value)
              {
                $emailtext .= $key . " = " .$value ."\n\n";
              }
              mail($payer_email, "Live-INVALID IPN", $emailtext . "\n\n" . $req);
            }
        }

        # Functionality needs to be added beyond this point to execute
        # and wait for the result returned by what will be our shell script

    }
}

?>

现在奇怪的是我可以记录我的帖子字段，但脚本不会返回VALID或INVALID字段。我必须指出，这个脚本在我拥有的共享主机帐户上运行得非常好。我认为最初它可能与权限有关，但据我所知，一切都是有序的。有谁知道问题可能是什么？

显然问题很简单。在构造函数中调用域之前，请求需要www.。

 public function __construct($mode = 'sandbox'){
    if($mode == 'live')
        $this->_url = 'https://www.paypal.com/cgi-bin/webscr';
    else
        $this->_url = "https://www.sandbox.paypal.com/cgi-bin/webscr";
}

PHP cURL没有返回结果 - Paypal IPN
