【问题描述】：
我正在通过我的网站上的贝宝进行付款，但我在使用即时付款通知时遇到了问题，
我从 paypal 的示例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);
}
}
?>
如果我删除邮件功能，一切都按预期工作，日志会写入一次，IPN 历史记录中会出现“已发送”状态。
现在，当使用邮件功能时，每件事都会执行大约 8 次，这意味着 8 条日志写入和 8 封电子邮件发送。 同时IPN历史一直在“重试”状态一段时间后变成“错误”状态，提到http响应字段在这两种情况下都是空的。
感谢您的时间伙伴。

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 日志也没有显示任何错误...
