Using wp_remote_get with cookies WordPress

Gabriel Reguly answers:

Hi Julio,

Sorry, but $5 is not worth a lot of time.

So I'll help you with the basic info and you will have to find yourself the correct values for reddit ;-)


$url = 'http://www.reddit.com/r/redheads/'; // NSFW

$cookie = new WP_Http_Cookie( 'over18' );
$cookie->name = 'over18';
$cookie->value = '8cfed3ce4e1c0bd7d2763c2839a689b69e5f8d6c';
$cookie->expires = mktime( 0, 0, 0, date('m'), date('d') + 7, date('Y') ); // expires in 7 days
$cookie->path = '/';
$cookie->domain = '.reddit.com';

$cookies[] = $cookie;

$cookie2 = new WP_Http_Cookie( 'reddit_first' );
$cookie2->name = 'reddit_first';
$cookie2->value = '%7B%22firsttime%22%3A%20%22first%22%7D';
$cookie2->expires = mktime( 0, 0, 0, date('m'), date('d') + 7, date('Y') );
$cookie2->path = '/';
$cookie2->domain = '.reddit.com';

$cookies[] = $cookie2;

$args = array( 'cookies' => $cookies );

$content = wp_remote_get( $url, $args );



Good luck,
Gabriel


Edit: Thanks for the prize money.

If I knew you accepted a cURL solution, I would have shared mine before ( it does a login, then loads a page )

Gerard answers:

Do not use wp_remote_get as you have to deal with POST requests and some issues with cookies.
Use curl instead:


/* cookie file */
$cookie_file = dirname(__FILE__) . '/cookie.txt';
/* url we need to access */
$confirmation_url = 'http://www.reddit.com/r/redheads/over18?dest=%2Fr%2Fredheads';
/* perform a post request with our cookie. using curl */
$handle = curl_init();
curl_setopt($handle, CURLOPT_URL, $confirmation_url);
curl_setopt($handle, CURLOPT_COOKIEJAR, $cookie_file);
curl_setopt($handle, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_POST, true );
curl_setopt($handle, CURLOPT_FOLLOWLOCATION, true );
curl_setopt($handle, CURLOPT_POSTFIELDS, array('over18' => 'yes', 'uh' => ''));
/* reponse contains our page */
$response = curl_exec($handle);

Note: $response will be your page in HTML.
