【问题描述】：
我不能使用 cURL，安装在我的 web 主机上的无法更改的版本不支持 TLS。
我现在正在尝试使用 fsockopen 看看是否可以使用 IPN。
它只是挂起，浏览器抛出连接超时。
PHP 7，open_ssl 已启用
<?php
header('HTTP/1.1 200 OK');
$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'];
$req = 'cmd=_notify-validate'; // Add 'cmd=_notify-validate' to beginning of the acknowledgement
foreach ($_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/1.1\r\n"; // HTTP POST request
$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.sandbox.paypal.com', 443, $errno, $errstr, 30);
// Send the HTTP POST request back to PayPal for validation
fputs($fp, $header . $req);
while (!feof($fp)) { // While not EOF
$res = trim(fgets ($fp, 1024));
if (strcmp ($res, "VERIFIED") == 0) { // Response contains VERIFIED - process notification
file_put_contents('./log_'.date("j.n.Y").'.txt', 'VERIFIED', FILE_APPEND);
}
else if (strcmp ($res, "INVALID") == 0) { Response contains INVALID - reject notification
file_put_contents('./log_'.date("j.n.Y").'.txt', 'INVALID', FILE_APPEND);
}
}
//close
fclose($fp);
?>
更新
所以这似乎是我当前代码的问题。我使用以下内容查看是否可以与 PayPal 通话。
<?php
$site = "sandbox.paypal.com";//works
$port = 443;
$fp = fsockopen($site, $port, $errno, $errstr, 30);
if(!$fp){
echo "<b>The port is NOT open!</b>";
}else{
echo "<b>The port is open!</b>";
fclose($fp);
}
?>
结果是The port is open!
更新 2
好的，我现在使用以下代码从 IPN 模拟器获得响应。我遇到的其他问题是我未能使用我的听众的 FQDN 并离开了 http://。
所以现在下一个问题是$res = trim($res); 总是空白，但我的帖子变量不是。这是因为它是沙盒吗？

【问题讨论】：
-
如果您的服务器环境不支持 TLS，这意味着它必须很旧。像10岁以上。如果他们无法让您进入具有更新环境且运行 TLS 的新服务器，我强烈建议您切换主机。

好的，所以我解决了我的问题，但现在 $res 始终为空白。我没有收到 VERIFIED 或 INVALID 回复。
