I'm trying to develop a query class that will return the data available through the CEI (INSS).
So far I have the following codes:
/**
* Retorna os parâmetros necessários para a consulta;
* @throws Exception
*/
public static function getParams()
{
require 'vendor/autoload.php';
$client = new GuzzleHttp\Client();
$crawler = $client->get('http://www2.dataprev.gov.br/PortalSalInternet/faces/pages/calcContribuicoesEmpresasEOrgaosPublicos/inicio.xhtml');
$body = $crawler->getBody();
$headers = $crawler->getHeaders();
$cookie = $headers['Set-Cookie'][1];
if (!method_exists('phpQuery', 'newDocumentHTML'))
require_once __DIR__ . DIRECTORY_SEPARATOR . 'phpQuery-onefile.php';
$doc = phpQuery::newDocumentHTML($body, $charset = 'utf-8');
$token = phpQuery::pq('form#formInicial input[name="DTPINFRA_TOKEN"]')->val();
$viewstate = phpQuery::pq('form#formInicial input[name="javax.faces.ViewState"]')->val();
$imgCaptcha = phpQuery::pq('form#formInicial img[name="formInicial:j_id41"]')->attr('src');
$urlCaptcha = 'http://www2.dataprev.gov.br' . $imgCaptcha;
$captchaBase64 = 'data:image/png;base64,' . base64_encode(file_get_contents($urlCaptcha));
if ($viewstate == '')
throw new Exception('Erro ao recuperar viewstate');
return [
'captcha' => $urlCaptcha,
'captchaBase64' => $captchaBase64,
'viewstate' => $viewstate,
'cookie' => $cookie,
'token' => $token,
];
}
/**
* Metodo para realizar a consulta
*
* @param string $cei CEI
* @param string $captcha Captcha
* @param string $viewstate ViewState
* @param string $token Token
* @throws Exception
* @return array Dados da empresa
*/
public static function consulta($cei, $captcha, $viewstate, $token, $stringCookie)
{
require 'vendor/autoload.php';
$arrayCookie = explode(';', $stringCookie);
$urlCurl = 'http://www2.dataprev.gov.br/PortalSalInternet/faces/pages/calcContribuicoesEmpresasEOrgaosPublicos/inicio.xhtml';
$client = new GuzzleHttp\Client();
$param = [
'body' => [
'formInicial' => 'formInicial',
'DTPINFRA_TOKEN' => $token,
'formInicial:categoria' => 'EMPRESA',
'formInicial:tipoDoDocumento' => 'CEI',
'formInicial:cei' => $cei,
'formInicial:captchaId' => $captcha,
'formInicial:botaoPrincipalConfirmar' => 'Confirmar',
'javax.faces.ViewState' => $viewstate
]
];
$request = $client->createRequest('POST', $urlCurl, $param);
$request->setHeader('Host', 'www2.dataprev.gov.br');
$request->setHeader('User-Agent', 'Mozilla/5.0 (Windows NT 6.1; rv:32.0) Gecko/20100101 Firefox/32.0');
$request->setHeader('Accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8');
$request->setHeader('Accept-Language', 'pt-BR,pt;q=0.8,en-US;q=0.6,en;q=0.4');
$request->setHeader('Accept-Encoding', 'gzip, deflate');
$request->setHeader('Referer', 'http://www2.dataprev.gov.br/PortalSalInternet/faces/pages/calcContribuicoesEmpresasEOrgaosPublicos/inicio.xhtml');
$request->setHeader('Cookie', $arrayCookie[0]);
$request->setHeader('Connection', 'keep-alive');
$response = $client->send($request);
echo $response;
}
But I have the following problem:
The site works with session and sends the form request to the same page validating this session;
When sending the consulta() method, errors usually occur as an expired session, or it only loads the splash screen filling in the data.
Has anyone done anything like this or could it have helped me solve this?
