Почему такой код не сохраняет куки?

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://ocservice.taobao.com/cookieController/processUserCookie?site=CN_zh-CN_CNY_156&callback=jsonp_1546706091271_92560');
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . '/cookie.txt');

                'Host: www.google.ca',

curl_setopt($ch, CURLOPT_HTTPHEADER, $http_headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$output = curl_exec($ch);
curl_close($ch);
