php - Paypal 监听器 : Connection reset by peer?

Question

我已经尝试了所有方法，但在尝试验证/确认时总是“被同行重置”..
这是我的提炼代码:

<?php
header('HTTP/1.1 200 OK');

$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) // $_POST looks OK to me..
    $req .= "&$key=".urlencode(stripslashes($value));

$fp = fsockopen("ssl://www.sandbox.paypal.com", 443, $errno, $errstr, 60); // true

$header  = "POST /cgi-bin/webscr HTTP/1.1\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Conection: Close\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

fputs ($fp, $header . $req);
while (!feof($fp))
    {
    $res = fgets ($fp, 1024); // CONNECTION RESET BY PEER : (
    if ($res === "VERIFIED")    $response = "VERIFIED";
    if ($res === "INVALID") $response = "INVALID";
    }
fclose($fp);

为什么他们不跟我说话？!？

好的。找到了一些让我完成所有操作的示例代码:

- 在收到“已验证”后，我可以使用 3 年前的代码了:)
