Login to page with CURL

Question

I have the problem with login to the website using CURL. I read the session ID but to use it, I have to reload the page, which is associated with the change. How can I dynamically use the current session id?

     <?php
    $post = 'login=testowe12&ampregister=0&password=testowe12&cookie_check=1&_xfToken=&redirect='.urlencode("http://gsmx.co");

    $handle = curl_init('http://gsmx.co/logowanie/login');
    curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($handle, CURLOPT_HEADER, 1);     
    curl_setopt($handle, CURLOPT_HTTPHEADER, array(
    'Host: gsmx.co',
    'Content-Length: 93',
    'Cache-Control: max-age=0',
    'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',
    'Origin: http://gsmx.co',
    'User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36',
    'Content-Type: application/x-www-form-urlencoded',
    'Referer: http://gsmx.co/login',
    'Accept-Language: pl-PL,pl;q=0.8,en-US;q=0.6,en;q=0.4'));
    //'Cookie: xf_session='.$cookie["xf_session"].'; GCSCU_770734409090_H2=C=770734409090.apps.googleusercontent.com:S=81bef9fa0c3fbdaac13c33f8b709fc73474d3562.kvhqgGncJscCDSvW.7dde:I=1403792615:X=1403879015'));
    curl_setopt($handle, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($handle, CURLOPT_POSTFIELDS, $post);
    $output = curl_exec($handle);

    preg_match('/^Set-Cookie:\s*([^;]*)/mi', $output, $cookie);
    parse_str($cookie[1], $cookie);

    echo $cookie["xf_session"].'<br>'.$output;
?>

Answer 1

You need to use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE for this.

curl_setopt($handle, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($handle, CURLOPT_COOKIEFILE, 'cookie.txt');

This will keep all the cookies in cookie.txt and while making a new request cookies will be taken from same cookie.txt file. This way you'll be able to maintain the session on successive HTTP requests.

如果要保持登录状态，请在登录后执行的所有curl请求中使用相同的cookie文件。
