Question

我有一个paypal ipn listener ipn.php，它链接到数据库并使用通知信息更新通知表，然后通过电子邮件将密钥发送给付款人电子邮件。

这是ipn.php

<?php    

include("class.phpmailer.php");
include("class.smtp.php");

include("config.php");

    //Send an empty HTTP 200 OK response to acknowledge receipt of the notification

ini_set("log_errors", "On");
ini_set("error_log", "error.log");

$con = mysql_connect($dbhost,$dbuser,$dbpass);

if($con == false){ echo "Could not connect to mysql: " . mysql_error();}
else{echo "Connected to database successfully!";}

header('HTTP/1.0 200 OK');
header('Connection: close');


$item_name        = $_POST['item_name'] != null ? $_POST['item_name'] : "none"; 
$item_number      = $_POST['item_number'] != null ? $_POST['item_number'] : "none";
$payment_status   = $_POST['payment_status'] != null ? $_POST['payment_status'] : "none";
$payment_amount   = $_POST['mc_gross'] != null ? $_POST['mc_gross'] : "none";
$payment_currency = $_POST['mc_currency'] != null ? $_POST['mc_currency'] : "none";
$txn_id           = $_POST['txn_id'] != null ? $_POST['txn_id'] : "none";
$receiver_email   = $_POST['receiver_email'] != null ? $_POST['receiver_email'] : "none";
$payer_email      = $_POST['payer_email'] != null ? $_POST['payer_email'] : "none";

// Build the required acknowledgement message out of the notification just received
$req = 'cmd=_notify-validate';               // Add 'cmd=_notify-validate' to beginning of the acknowledgement

foreach ($_POST as $key => $value) {         // Loop through the notification NV pairs
    $value = urlencode(stripslashes($value));  // Encode these values
    $req  .= "&$key=$value";                   // Add the NV pairs to the acknowledgement
}

// Set up the acknowledgement request headers
$header  = "POST /cgi-bin/webscr HTTP/1.0\r\n";     // HTTP POST request
$header .= "Host: www.paypal.com\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

// Open a socket for the acknowledgement request
$fp = fsockopen('ssl://www.paypal.com', 443, $errno, $errstr, 30);

// Send the HTTP POST request back to PayPal for validation
fputs($fp, $header . $req);


    error_log("reached");

    $res = stream_get_contents($fp,1024);           // Get the acknowledgement response

    while(!feof($fp)){
        $res = trim(fgets($fp,1024));

        if(empty($res)){
            break;
        }
    }

    $res = trim(fgets($fp,1024));

    if (strcmp ($res, "VERIFIED") == 0) {  // Response contains VERIFIED - process notification


        $sql = "INSERT INTO notifications VALUES( DEFAULT, '$item_name','$item_number','$payment_status','$payment_amount','$payment_currency','$txn_id','$receiver_email','$payer_email')";

        mysql_select_db($dbname,$con);

        if(!mysql_query($sql)){
            error_log(mysql_error());
        }

        if(strcmp($payment_status,"Completed") == 0){

            $sql = "";
            $sql = "INSERT INTO activationkeys VALUES(DEFAULT, '$key', '0', $item_number)";
            if(!mysql_query($sql)){
                error_log("Could not execute query: " . mysql_error());
            }

            $mail = new PHPMailer(true);

            //Send mail using gmail
            if($config_gmail){
                $mail->IsSMTP();
                $mail->SMTPAuth = true;
                $mail->SMTPSecure = "tls";
                $mail->Host = "smtp.gmail.com";
                $mail->Port = 587;
                $mail->Username = $config_gmail_username;
                $mail->Password = $config_gmail_password;
            }

            //Typical mail data
            $mail->AddAddress($payer_email,"Donator");
            $mail->SetFrom($config_merchant_domain,$config_merchant_name);
            $mail->Subject = "You're Donation Key";
            $mail->Body = "Hey, your payment was successful.\nHere's your key: " . $key;

            if(!$mail->send()){
                error_log("Message could not be sent: " . $mail->ErrorInfo );
            }


        }
        mysql_close($con);



        // Authentication protocol is complete - OK to process notification contents

        // Possible processing steps for a payment include the following:

        // Check that 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

    } 
    else if (strcmp ($res, "INVALID") == 0) { //Response contains INVALID - reject notification

        // Authentication protocol is complete - begin error handling
        // Send an email announcing the IPN message is INVALID
        $mail_From    = "IPN@example.com";
        $mail_To      = "Your-eMail-Address";
        $mail_Subject = "INVALID IPN";
        $mail_Body    = $req;

        mail($mail_To, $mail_Subject, $mail_Body, $mail_From);
    }

fclose($fp);  // Close the file

function get_new_key(){
    $keycharacters = "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    $key = "";
    for($i = 0; $i < 10; $i++){
        $key .= $keycharacters[rand(0,strlen($keycharacters)-1)];
    }
    return $key;
}

问题是，当我通过沙箱发送时，它会更新数据库并通过电子邮件发送密钥，但是当我尝试使用代码时，它没有做任何事情......

我不知道问题是什么。

Answer 1

收到任何错误？检查IPN历史记录日志？如果进行API调用，请确保使用LIVE凭证，如果仍有问题，请将帐号或电子邮件地址告诉我，或者将票证提交至paypal.com/mts

Answer 2

我已经设法修复它，问题在于我正在阅读响应的方式，我现在使用;

if (!$fp) {  
        error_log("could not open socket"); 
    } else {  
        fputs ($fp, $header . $req);  
        while (!feof($fp)) {  
            $res = fgets ($fp, 1024);  
            if (strcmp ($res, "VERIFIED") == 0){
                break;
            }
        }
    }

PayPal IPN侦听器使用沙箱而不是直播
