Curl with session/cookie


Scanu

Recommended Posts

Hi to everyone, I'm new to the forum and I'm posting here because I ended up in a logical problem for my next script development.

I need to get some data of external websites (with vbulletin board), perfectly legal.

Using file_get_contents i can print the page content on my server and then use jquery's powerful selectors to get my data.

 

The problem is that these data are shown only to logged in users so i would need this script (maybe using cURL?) to either login to the external website and then persists the connection or maybe if the user who is executing my script is already logged in that website then use his login? (most likely impossible I think..)

 

This is my code so far (found on some sites and merged into this)

$data = array('vb_login_username' => 'Scanu', 'vb_login_password' => 'grgfgrgrfbtgbt');
$ch = curl_init(); 
curl_setopt($ch,    CURLOPT_URL,            "http://www.vbulletin.org/forum/login.php?do=login"); 
curl_setopt($ch,    CURLOPT_AUTOREFERER,         true); 
curl_setopt($ch,    CURLOPT_COOKIESESSION,         true); 
curl_setopt($ch,    CURLOPT_FAILONERROR,         false); 
curl_setopt($ch,    CURLOPT_FOLLOWLOCATION,        false); 
curl_setopt($ch,    CURLOPT_FRESH_CONNECT,         true); 
curl_setopt($ch,    CURLOPT_HEADER,             true); 
curl_setopt($ch,    CURLOPT_POST,                 true); 
curl_setopt($ch,    CURLOPT_RETURNTRANSFER,        true); 
curl_setopt($ch,    CURLOPT_CONNECTTIMEOUT,     30); 
curl_setopt($ch,    CURLOPT_POSTFIELDS,         $data); 
$result = curl_exec($ch); 
curl_close($ch);


$pattern = "#Set-Cookie: (.*?; path=.*?;.*?)\n#"; 
preg_match_all($pattern, $result, $matches); 
array_shift($matches); 
$cookie = implode("\n", $matches[0]); 


$ch = curl_init(); 
curl_setopt($ch,    CURLOPT_URL,            "http://www.vbulletin.org/forum/"); 
curl_setopt($ch,    CURLOPT_COOKIE,                $cookie); 
curl_setopt($ch,    CURLOPT_AUTOREFERER,         true); 
curl_setopt($ch,    CURLOPT_COOKIESESSION,         true); 
curl_setopt($ch,    CURLOPT_FAILONERROR,         false); 
curl_setopt($ch,    CURLOPT_FOLLOWLOCATION,        false); 
curl_setopt($ch,    CURLOPT_FRESH_CONNECT,         true); 
curl_setopt($ch,    CURLOPT_HEADER,             false); 
curl_setopt($ch,    CURLOPT_POST,                 false); 
curl_setopt($ch,    CURLOPT_RETURNTRANSFER,        true); 
curl_setopt($ch,    CURLOPT_CONNECTTIMEOUT,     30); 
$result = curl_exec($ch); 
curl_close($ch);
echo $result;
?>

It just shows the same page for unregistered users. Any help or advice is appreciated, i'm very new to this type of script..
