paypal IPN在使用电子邮件功能

我在我的网站上通过paypal实施付款，而我在使用即时付款通知时遇到了问题，

我从paypal的例子中复制了以下基本代码：

<?php
// CONFIG: Enable debug mode. This means we'll log requests into 'ipn.log' in the same directory.
// Especially useful if you encounter network errors or other intermittent problems with IPN (validation).
// Set this to 0 once you go live or don't require logging.
define("DEBUG", 1);
// Set to 0 once you're ready to go live
define("USE_SANDBOX", 1);
define("LOG_FILE", "./ipn.log");

$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 post from PayPal system and add 'cmd'
$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";
}
// Post IPN data back to PayPal to validate the IPN data is genuine
// Without this step anyone can fake IPN data
if(USE_SANDBOX == true) {
    $paypal_url = "https://www.sandbox.paypal.com/cgi-bin/webscr";
} else {
    $paypal_url = "https://www.paypal.com/cgi-bin/webscr";
}
$ch = curl_init($paypal_url);
if ($ch == FALSE) {
    return FALSE;
}
curl_setopt($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);
if(DEBUG == true) {
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLINFO_HEADER_OUT, 1);
}

// Set TCP timeout to 30 seconds
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));

$res = curl_exec($ch);
if (curl_errno($ch) != 0) // cURL error
    {
    if(DEBUG == true) { 
        error_log(date('[Y-m-d H:i e] '). "Can't connect to PayPal to validate IPN message: " . curl_error($ch) . PHP_EOL, 3, LOG_FILE);
    }
    curl_close($ch);
    exit;
} else {
        // Log the entire HTTP response if debug is switched on.
        if(DEBUG == true) {
            error_log(date('[Y-m-d H:i e] '). "HTTP request of validation request:". curl_getinfo($ch, CURLINFO_HEADER_OUT) ." for IPN payload: $req" . PHP_EOL, 3, LOG_FILE);
            error_log(date('[Y-m-d H:i e] '). "HTTP response of validation request: $res" . PHP_EOL, 3, LOG_FILE);
        }
        curl_close($ch);
}
// Inspect IPN validation result and act accordingly
// Split response headers and payload, a better way for strcmp
$tokens = explode("\r\n\r\n", trim($res));
$res = trim(end($tokens));
if (strcmp ($res, "VERIFIED") == 0) {


    mail('try@website.com', 'New Order', 'New Order', 'From: support@website.com');



    if(DEBUG == true) {
        error_log(date('[Y-m-d H:i e] '). "Verified IPN: $req ". PHP_EOL, 3, LOG_FILE);
    }
} else if (strcmp ($res, "INVALID") == 0) {
    // log for manual investigation
    // Add business logic here which deals with invalid IPN messages
    if(DEBUG == true) {
        error_log(date('[Y-m-d H:i e] '). "Invalid IPN: $req" . PHP_EOL, 3, LOG_FILE);
    }
}
?>

如果删除邮件功能，一切都按预期工作，则会写入一次日志并发送＆＃34;＆＃34;国家出现在IPN历史上。

现在，当使用邮件功能时，所有内容都执行了8次，这意味着发送了8个日志文件和8封电子邮件。 与此同时，IPN历史记录继续进行＆＃34;重试＆＃34;国家变成＆＃34;错误＆＃34;状态一段时间后，提到http响应字段在两种情况下都是空的。

感谢您的时间伙伴。

修改1：

这是日志文件中的内容：

[2016-04-27 12:19 America/New_York] HTTP request of validation request:POST /cgi-bin/webscr HTTP/1.1
Host: www.sandbox.paypal.com
Accept: */*
Connection: Close
Content-Length: 1052
Content-Type: application/x-www-form-urlencoded
Expect: 100-continue



for IPN payload: bla bla bla
[2016-04-27 12:19 America/New_York] HTTP response of validation request: HTTP/1.1 100 Continue

HTTP/1.1 200 OK

bla bla bla

VERIFIED

我认为一切正常，apache log doesen也没有显示任何错误...

解决，请参阅下面的解决方案。

我认为你的邮件功能失败并给出了200以外的标题，paypal希望这是8次重试的原因。 无论如何，我编辑了代码并将mail（）函数放在try catch块中并记录错误。

Okey我终于找到了解决方案，这只适用于使用虚拟专用服务器的人。对我来说问题是邮件功能耗时太长，可能会在IPN监听器中产生超时，

解决这个问题：
- 首先，在命令提示符下获取主机名tiping hostname
- 然后我编辑主机文件：sudo nano /etc/hosts
  -----------并更改此行 - ＆gt; 127.0.0.1 localhost myhostname
  -----------到这一行 - ＆gt; 127.0.0.1 localhost localhost.localdomain myhostname
