Question

我遇到了paypal IPN回调问题。 Paypal的IPN回调在沙盒环境中停止工作。

过去几周我一直在测试我的客户的网站，并且它一直运行正常 - 付款已经完成，并且回调IPN被发送回网站，确认付款并更新网站的数据库

我的代码中没有任何更改，它突然停止工作。付款仍然存入并保存在paypal帐户中，但IPN始终在重试...它没有完成。

以下是使用中的代码：

<?php

// STEP 1: read POST data

// 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 [link removed] 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);

……

?>

将一些输出发送到文本文件，我发现它通过第一步并在第二步停止

if( !($res = curl_exec($ch)) ) {

我已经向PayPal提交了三个帮助请求，但仍未得到他们的答复。

cURL请求启动HTTP POST回PayPal以验证IPN消息。如果它在此步骤停止，则表示您执行从PayPal接收IPN POST，但是您在连接回PayPal时遇到问题。

// error_log("Got " . curl_error($ch) . " when processing IPN data");包含哪些内容？

要解决此问题，请测试从服务器到以下地址的HTTPS连接：

例如，您可以直接从服务器运行cURL（假设您已获得SSH访问权限）;

curl -v https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_notify-validate

这应该返回类似于以下内容的内容：

如果收到超时或SSL握手错误，则需要单独进行调查。
