我得到了脚本的登录部分，但是第二部分不起作用。

<?php

// Curl login
$login = "http://****/admin/index.php?route=common/login";
$credentials = "username=admin&password=****";
$cookie = "cookie.txt";

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $login); 
curl_setopt ($ch, CURLOPT_POST, 1); 
curl_setopt ($ch, CURLOPT_POSTFIELDS, $credentials); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
$exec = curl_exec ($ch); 

// Logged in, fetch the post data
$url = $_POST['order'];
$return = $_POST['return'];

// Request the protected invoice page
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt($ch, CURLOPT_URL, $url);
$response = curl_exec($ch);
curl_close($ch);

$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

// Mail it
mail('****@gmail.com', 'Invoice', $response, $headers);

// Dump it
    var_dump($response);
?>

现在，如果我提供了错误的凭据，那么我会收到带有登录错误的管理员登录页面，但是如果我提供正确的凭据，我只会收到一封空电子邮件。var_dump在脚本结束时返回string(0).

如果登录管理，它是可访问的$url = $_POST['order'];，它是一个正确的 URL，它会返回订单发票页面。

在尝试获取受保护的页面后，我是否应该重新初始化 curl。所以首先登录>关闭卷曲然后重新初始化并获取页面还是我错过了一些选项？

我的重申： 

<?php

    // Curl login
    $login = "http://***/admin/index.php?route=common/login";
    $credentials = "username=***&password=***";
    $cookie = "cookie.txt";

    // Initialize
    $ch = curl_init(); 
    curl_setopt ($ch, CURLOPT_URL, $login); 
    curl_setopt ($ch, CURLOPT_POSTFIELDS, $credentials); 
    curl_setopt ($ch, CURLOPT_POST, 1); 
    curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
    curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie);
    curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1)
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
    curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
    curl_setopt ($ch, CURLOPT_HEADER, 0);
    curl_setopt ($ch, CURLOPT_VERBOSE, 0);

    // Login - use 
    $exec = curl_exec ($ch); 

    // Logged in, fetch the post data
    $url = $_POST['order'];
    $return = $_POST['return'];

    // Request the protected invoice page
    curl_setopt($ch, CURLOPT_URL, $url);
    $response = curl_exec($ch);

    echo '<br /><br />-----------------------------------------------------------------------------------------------------------------<br /><br />';
    var_dump($response);

    echo '<br /><br />-----------------------------------------------------------------------------------------------------------------<br /><br />';
    var_dump(curl_getinfo($ch));

    echo '<br /><br />-----------------------------------------------------------------------------------------------------------------<br /><br />';
    var_dump(curl_error($ch));

    echo '<br /><br />-----------------------------------------------------------------------------------------------------------------<br /><br />';
    echo $url;

    echo '<br /><br />-----------------------------------------------------------------------------------------------------------------<br /><br />';

    // Close the funnel
    curl_close($ch);

    $headers  = 'MIME-Version: 1.0' . "\r\n";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

    // Mail it
    mail('***@gmail.com', 'Predracun', $response, $headers);
?>

这就是我现在拥有的，当我运行脚本时它给我一个 500 错误。
