Salve,

Sto lavorando su un tool online di similarità genetica, ed ho necessità di automatizzare il procedimento di recupero del risultato. Il form di input online è composto da diversi combobox, una textarea(UserData) e un bottone di tipo file.

Ho recuperato tramite plugin firefox, i dati inviati via post dal form, e sono i seguenti:

Il mio codice php, invece, è semplicemente questo:

$url = 'http://web.cbio.uct.ac.za/ITGOM/tools/itgomEngine.php';     


$postData = array();
$postData['SMeasure'] = '3';
$postData['SOntology'] = '2';
$postData['SFamily'] = '2';
$postData['IncludeIEA'] = '1';
$postData['SApproach'] = '2';
$postData['Identifier'] = '1';
$postData['UserData'] = "";
$postData['InputFile'] = "@C:\Users\Matteo\Desktop\test.txt";


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);


$response = curl_exec($ch);


echo $response;

Il problema è che riesco a settare tutte le diverse opzioni, ad eccezione del file in input ottenendo l'errore "For the gene list file, only txt format are recommended!". Se invece provo così:

$postData['InputFile'] = "@C:\Users\Matteo\Desktop/test.txt;type=text/plain";

ottengo l'errore "Running fails! Gene list, i.e., a list of interesting genes is missing!".

Qualche idea in merito? Grazie!
