我正在使用PayPal IPN模拟器测试我的IPN通知程序。使用以下方法验证响应时:

 $fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

我获得了无效

然而,当我使用这个(正确的)验证响应时:

 $fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);

它不会返回VERIFIED OR INVALID,只返回false。

完整代码:

// read the data send by PayPal
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
    $value = urlencode(stripslashes($value));
    $req .= "&$key=$value";
}

// post back to PayPal system to validate
$header = "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);

if (!$fp) {
    //http error
}
else {
    fputs ($fp, $header . $req);
    while (!feof($fp)) {
        $res = fgets ($fp, 1024);
        if (strcmp ($res, "VERIFIED") == 0) {
            //verified
        }
        else if (strcmp ($res, "INVALID") == 0) {
            //invalid
        }
    }
    fclose ($fp);
}
