Good morning, I'm trying, after logging into a website, to extract some information, however, after logging into the site, I need to send a new post to select the data. The problem is that in this second request the screen goes blank. I already put a condition with curl_error ($ ch), but it does not return any error, so not what could be wrong. Can anyone help me with this? The code I'm using is this:
$arquivo = __DIR__ . DIRECTORY_SEPARATOR . md5(rand().time());
file_put_contents($arquivo, '');
$ch = curl_init();
$url = "https://sistemas.anatel.gov.br/sis/cadastrosimplificado/pages/acesso/login.xhtml?i=0&codSistema=649";
// CONFIGURANDO A URL
curl_setopt($ch, CURLOPT_URL, $url); //DEFINE A URL PARA ACESSAR
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'SISLogin=********&SISSenha=********&SISQSmodulo=*****');
curl_setopt($ch, CURLOPT_COOKIEJAR, $arquivo);
curl_setopt ($ch, CURLOPT_REFERER, $url);
// EXECUTANDO A SESSÃO COM UTF-8
$resultado = curl_exec($ch);
curl_setopt($ch, CURLOPT_URL, 'http://focus.anatel.gov.br/focus/Tratar_Solicitacao/pesquisa.asp?SISQSmodulo=13863');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, 1);

curl_close($ch);
