登录Curl在这个网站上

Question

我尝试使用curl登录this website，但我遇到了问题（或更多）没有任何反应，我没有得到任何数据......

$urlRef ='grossiste-informatique.com/grossiste/detail_article_popup.php?code_article='. $s['reference'];

$urlLogin = 'grossiste-informatique.com/grossiste/auth_process.php';

$username = 'xxxxxx';
$password = 'xxxxxx';

$ch = curl_init($urlRef);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);

$cl = utf8_encode(curl_exec($ch));
