Сохранит куки curl php

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');

        $http_headers = array(

                        'Host: www.google.ca',

                        'User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2',

                        'Accept: */*',

                        'Accept-Language: en-us,en;q=0.5',

                        'Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7',

                        'Connection: keep-alive'

                      );

        curl_setopt($ch, CURLOPT_HEADER, true);

        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);
