Php Paypal:无效的IPN问题

您好，我知道有很多问题已经在这么相关的我的问题，但我没有得到解决，从他们中的任何一个。我已经实现了贝宝。它运行良好。现在我想在我的paypal实现中实现ipn。我搜索了一下，找到了一些代码。我已经实现了，但是我得到了无效的ipn。我可以从paypal交易中获得所有细节，但对于ipn来说，它总是无效的。我在DoExpressCheckoutPayment.php文件中使用了以下代码

$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: 
$header .= "Host: www.sandbox.paypal.com:443\r\n";
//$header .= "Host: www.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);
$fp =fsockopen('ssl://www.sandbox.paypal.com',443,$err_num,$err_str,30);
echo('<br>'.$req);
// 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 (!$fp)
{
    echo(' HTTP ERROR');
}
else
{
    fputs ($fp, $header . $req);
    while (!feof($fp))
    {
        $res = fgets ($fp, 1024);
        echo('<br> res is '.$res);
    if (strcmp ($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: me@mybiz.com";
        $mail_To = "xxxx@gmail.com";
        $mail_Subject = "VERIFIED IPN";
        $mail_Body = $req;
        foreach ($_SESSION as $key => $value)
        {
            $emailtext .= $key . " = " .$value ."\n\n";
        }
        if(mail($mail_To, $mail_Subject, $emailtext . "\n\n" . $mail_Body, $mail_From))
        echo('<br>mail 1 sent');
        else
        echo('<br>mail1 not sent');
    }
    else if (strcmp ($res, "INVALID") == 0)
    {
        // log for manual investigation
        $mail_From = "From: me@mybiz.com";
        $mail_To = "xxx@gmail.com";
        $mail_Subject = "INVALID IPN";
        $mail_Body = $req;
        foreach ($_SESSION as $key => $value)
        {
            $emailtext .= $key . " = " .$value ."\n\n";
        }
        if(mail($mail_To, $mail_Subject, $emailtext . "\n\n" . $mail_Body, $mail_From))
        echo('<br>mail sent');
        else
        echo('<br>not sent');
    }
}
fclose ($fp);
}

我收到以下电子邮件：

**notify_url = http://www.mysite.com/paypal/DoExpressCheckoutPayment.php
cmd=_notify-validate&notify_url=http%3A%2F%2Fwww.mysite.com%2Fpaypal%2FDoExpressCheckoutPayment.php**

我注意到的一件事是，我没有从$\u POST得到任何东西。我的$\u帖子是空的。 请告诉我哪里错了。

谢谢

请在此处尝试此代码。它与您上面使用的略有不同。它对我有用

    <?php
    $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";
    $header .= "Content-Type: application/x-www-form-urlencoded\r\n";
    $header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
    $fp = fsockopen ('ssl://www.sandbox.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

    } else {
        fputs ($fp, $header . $req);
            while (!feof($fp)) {
            $res = fgets ($fp, 1024);
            if (strcmp ($res, "VERIFIED") == 0) {
                //Process Order
            }else if (strcmp ($res, "INVALID") == 0) {
                //Send Email To You 
            }
        }

        fclose ($fp);
    }
    ?>

作为返回链接提供的URL被调用2次！第一次来自PayPal并发送POST数据时，第二次重定向用户。您将看到一些GET变量，但它们非常无用（至少对于请求事务而言）

---

查看POST数据是否（在第一个请求中）的唯一方法是使用错误日志或类似的东西。

什么不起作用？像这样的东西很少可以通过查看代码来分类，而是通过在实时环境中进行调试来分类。您是否访问过您的paypay配置文件并将ipn设置为on@Awais-尝试将电子邮件功能置于有效/无效语句之外，并将从PP收到的

$req

字符串发送给您自己。然后您可以检查它未被正确处理的原因。@pekka。我收到了一封无效的电子邮件ipn@Awais-您的脚本发回包含PP发送的所有IPN变量的数据。PP然后发回有效或无效的响应，说明您收到的数据是否为合法付款。你能将无效电子邮件的内容粘贴到pastebin.com吗？@Christopher。但是哥们儿，邮局里什么都没有$_邮件是空的。好的，告诉我一件事，$\u POST中的值是由PP设置的还是由我设置的？如果它是由PP设置的，那么我什么也得不到。如果是我设置的，请告诉我在哪里设置这些？您收到的无效电子邮件是否包含

$req

字符串的内容？是的，这是cmd=\u notify-validate¬ify\u url=http%3A%2F%2Fwww.mysite.com/paypal%2FDoExpressCheckoutPayment.phpAfraid我不太确定。。我能想到的最后一件事是确保您从IPN测试仪发送了正确的IPN。还有，你想把它发送给你的本地主机吗？@Christopher。尝试了您的代码，但没有任何post数据。并且有同样的反应

    <?php
    $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";
    $header .= "Content-Type: application/x-www-form-urlencoded\r\n";
    $header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
    $fp = fsockopen ('ssl://www.sandbox.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

    } else {
        fputs ($fp, $header . $req);
            while (!feof($fp)) {
            $res = fgets ($fp, 1024);
            if (strcmp ($res, "VERIFIED") == 0) {
                //Process Order
            }else if (strcmp ($res, "INVALID") == 0) {
                //Send Email To You 
            }
        }

        fclose ($fp);
    }
    ?>
