Question

这是我的paypal api代码。我已经验证了这两个帐户，付款也已付款......但我仍然收到一封失败的电子邮件..这是我无法理解的原因...

<?php
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value)
{
    $value = urlencode(stripslashes($value));
    $req .= "&$key=$value";
}

    $header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
    $header .= "Content-Type: application/x-www-form-urlencoded\r\n";
    $header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

    $mode = $paymod_data['MODULE_PAYMENT_PAYPAL_TESTMODE'];

if ($mode == 'test')
{
    $fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
}
else
{
    $fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);
}

if (!$fp)
{
    // HTTP ERROR
     die ("Error");
}
else 
{   
    fputs ($fp, $header . $req);
    while (!feof($fp)) {
        $res = fgets ($fp, 1024);
        if (strcmp (trim($res), "VERIFIED") == 0) {
            // check the payment_status is Completed
            // check that txn_id has not been previously processed
            // check that receiver_email is your Primary PayPal email
            // check that payment_amount/payment_currency are correct
            // process payment
            echo strcmp ($res, "VERIFIED");
            echo strcmp (trim($res), "INVALID");
            mail("aks0130@gmail.com","sucess","aa gyi mail","From: demo2312@gmail.com");
        }
        else if (strcmp ($res, "INVALID") == 0) {
            // log for manual investigation
            echo strcmp (trim($res), "INVALID");
            echo strcmp (trim($res), "VERIFIED");
            mail("aks0130@gmail.com","fail","nahi aa gyi mail","From: demo2312@gmail.com");
        }
    }
fclose ($fp);
}
?>

我已经尝试了3-4天才能正确完成它，但是在静脉中......所以我回到了stackoverflow

用这个东西工作了好几天之后，我已经找到了一个令人担忧的Paypal IPN脚本，我在这里分享这个脚本，以便那些像我这样的人，在脚本中遇到问题可以从这里复制这个脚本并粘贴它在那里PHP notify_url页面...

    // 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

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


    }
    ?>

Paypal API不适用于简单的PHP文件
