PHP/cURL: Impossible de se connecter à distance

Question

J'essaie de me connecter à un système (qui se trouve être en utilisant le client SquirrelMail) en utilisant cURL et j'ai des problèmes.

Voici mon code PHP pertinent:

$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; 

Et quand je tente de l'exécuter, la page revient avec un message disant que je dois être connecté pour y accéder. Creuser dans ce fichier de connexion (redirect.php si vous êtes familier avec SquirrelMail), je vois cette erreur apparaît lorsque la variable login_username n'est pas définie.

Voici ma boucle sortie verbeuse:

* About to connect() to www.cwazy.net port 80 (#0) 
* Trying 72.18.206.197... * connected 
* Connected to www.cwazy.net (72.18.206.197) port 80 (#0)

Toutes les idées?

Answer 1

initial POST renvoie le cookie:

Set-Cookie: SQMSESSID=6d70837e874750f37df81f0aaaa48618 

mais ce cookie n'est pas envoyé par le client sur la prochaine requête GET. sm ne voit pas de session et essaie de créer une nouvelle avec un nouvel ID:

Set-Cookie: SQMSESSID=a6e32d5f2bd7a2ccca51edd2aa4ea143 

pour résoudre ce problème, vous pouvez dire curl pour stocker les cookies:

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

et vous devrez peut-être désactiver CURLOPT_FOLLOWLOCATION, et demandez simplement webmail.php dans un second appel à curl (en utilisant le même cookie jar avec la session authentifiée).

Answer 2

essayer ajouter à votre code

$cookie="cookie.txt"; 
    if(!file_exists($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); 

Hope this .. helpfull
