Instagram使用curl PHP登录

<?php
function instagram_login($data_sent_username,$data_sent_password){
  $data_filtered_data = instagram_gettoken();
  $data_rec_token = $data_filtered_data[0];
  $data_rec_mid = $data_filtered_data[1];
  $ch = curl_init();
  curl_setopt($ch,CURLOPT_URL,'https://www.instagram.com/accounts/login/ajax/');
  curl_setopt($ch,CURLOPT_POSTFIELDS,'username='.urlencode($data_sent_username).'&password='.urlencode($data_sent_password));
  curl_setopt($ch,CURLOPT_POST,1);
  curl_setopt($ch,CURLOPT_HEADER,0);
  curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,FALSE);
  curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,2);
  curl_setopt($ch,CURLOPT_FOLLOWLOCATION,CURLOPT_HTTPHEADER,array(
  'Host: www.instagram.com','Connection: keep-alive','Content-Length: 25','Origin: https://www.instagram.com','X-Instagram-AJAX: 1','Content-Type: application/x-www-form-urlencoded; charset=UTF-8','Accept: */*','X-Requested-With: XMLHttpRequest','X-CSRFToken: '.$data_rec_token.'','DNT: 1','Referer: https://www.instagram.com/accounts/login/','Accept-Encoding: gzip,deflate','Accept-Language: en-US','Cookie: mid='.$data_rec_mid.'; ig_pr=1; ig_vw=1319; csrftoken='.$data_rec_token.''));
  curl_setopt($ch,CURLOPT_COOKIEFILE,getcwd() . '/instagram_cookie.txt');
  curl_setopt($ch,CURLOPT_COOKIEJAR,CURLOPT_RETURNTRANSFER,CURLOPT_USERAGENT,"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.31 (KHTML,like Gecko) Chrome/26.0.1410.43 Safari/537.31");
  $data_rec_page = curl_exec($ch) or die(curl_error($ch));
  echo $data_rec_page;
}
function instagram_gettoken(){
  $ch = curl_init();
  curl_setopt($ch,'https://www.instagram.com/accounts/login/');
  curl_setopt($ch,array('application/x-www-form-urlencoded','charset=UTF-8'));
  curl_setopt($ch,like Gecko) Chrome/26.0.1410.43 Safari/537.31");
  curl_setopt($ch,CURLOPT_REFERER,"https://www.instagram.com/");
  $data_local_lines = file('instagram_cookie.txt');
  foreach($data_local_lines as $data_local_line) {
    if($data_local_line[0] != '#' && substr_count($data_local_line,"t") == 6) {
      $data_filter_tokens = explode("t",$data_local_line);
      $data_filter_tokens = array_map('trim',$data_filter_tokens);
      $data_filtered_data[] = $data_filter_tokens[6]; 
    }
  }
  return $data_filtered_data;
}
instagram_login("jackzett10","password");
?>

令人惊讶的输出是json格式,不知何故,无论输入什么密码都无关紧要,我总是得到相同的输出：

{"status":"ok","authenticated":false,"user":"jackzett10"}

我花了一些时间来获取令牌,并且每次请求都在中间位置,这样就不是问题了.
如果我删除标题数组中的cookie,输出不会改变
我从burbsuite的登录请求中获取了标题.
有谁知道我在这里做错了什么？
