joomla - 在 joomla 网站上使用 Curl 登录

Question

我无法让 php curl 登录到 joomla 网站。我无权访问该站点以下是我使用的类似代码。这是https网站。它给我的对象已移至此处。

<?php
$uname = $_POST['username'];
$upswd = $_POST['password'];
$url = "https://www.mytestjoomla.com/index.php?option=com_user&view=login";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE );
curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE );
curl_setopt($ch, CURLOPT_COOKIEJAR, realpath('./cookie.txt'));
curl_setopt($ch, CURLOPT_COOKIEFILE, realpath('./cookie.txt'));
curl_setopt($ch, CURLOPT_HEADER, TRUE );
$ret = curl_exec($ch);
if (!preg_match('/name="([a-zA-z0-9]{32})"/', $ret, $spoof)) {
    preg_match("/name='([a-zA-z0-9]{32})'/", $ret, $spoof);
}

// POST fields
$postfields = array();
$postfields['username'] = urlencode($uname);
$postfields['passwd'] = urlencode($upswd);
$postfields['option'] = 'com_user';
$postfields['task'] = 'login';
$postfields[$spoof[1]] = '1';
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
echo $ret = curl_exec($ch);

// Get logged in cookie and pass it to the browser
preg_match('/^Set-Cookie: (.*?);/m', $ret, $m);
$cookie=explode('=',$m[1]);
setcookie($cookie[0], $cookie[1]);
?>
