PHP / cURL: Impossibile l'accesso remoto

Question

Sto cercando di accedere ad un sistema (che sembra essere utilizzando il SquirrelMail client) utilizzando cURL e io 'm problemi.

Ecco il mio codice PHP rilevanti:

$handle = curl_init();

curl_setopt($handle, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($handle, CURLOPT_URL, $url);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, "login_username=myusername&secretkey=mypass&js_autodetect_results=0");

$output = curl_exec($handle);
curl_close($handle);
print $output;

e quando cerco di eseguirlo, la pagina torna con un messaggio che dice che bisogna effettuare il login per accedervi. Scavando nel file questo login (redirect.php se si ha familiarità con SquirrelMail), vedo questo errore viene in su quando il login_username variabile non è definita.

Ecco il mio output dettagliato ricciolo:

Tutte le idee?

Answer 1

l'iniziale POST restituisce il cookie:

Set-Cookie: SQMSESSID=6d70837e874750f37df81f0aaaa48618

, ma questo cookie non viene inviato dal client sulla prossima richiesta GET. SM non vede alcuna sessione e cerca di creare una nuova con un nuovo ID:

Set-Cookie: SQMSESSID=a6e32d5f2bd7a2ccca51edd2aa4ea143

Per risolvere questo problema si può dire curl per memorizzare i cookie:

curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');

e potrebbe essere necessario disattivare CURLOPT_FOLLOWLOCATION, e basta chiedere webmail.php in una seconda chiamata ad arricciarsi (utilizzando la stessa marmellata con la sessione autenticata).

Answer 2

Provare aggiungere questo al tuo codice

$cookie="cookie.txt";
    if(!file_exists($cookie)) {
       $fh = fopen($cookie, "w");
       fwrite($fh,"");
       fclose($fh);
    }

curl_setopt($curl_connection, CURL_COOKIEJAR, $cookie);
curl_setopt($curl_connection, CURL_COOKIEFILE, $cookie);
curl_setopt($curl_connection, CURL_VERBOSE, true);

Spero che questo disponibile ..
