cURL不适用于指定的站点

Question

Why does my curl not working correctly?

$ch = curl_init("http://www1.caixa.gov.br/loterias/loterias/megasena/megasena_resultado.asp");
curl_exec($ch);
curl_close($ch);

Answer 1

I discover the solution. This link require authentication cookie:

<?php
$ch = curl_init();
$options = array(
    CURLOPT_URL => 'http://www1.caixa.gov.br/loterias/loterias/megasena/megasena_pesquisa_new.asp',
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_MAXREDIRS => 50,
    CURLOPT_COOKIE => 'ASPSESSIONIDCSSRTDCR=KMKMJHPDIHNGBBLJFNGDJKGK; security=true',
    CURLOPT_RETURNTRANSFER => true

);
curl_setopt_array($ch, $options);
$senaHtml = curl_exec($ch);
curl_close($ch);
?>
