实现思路
（1）首先找到关注者多的，
（2）批量添加这个被关注的人的关注者

 '59bf3ba9518825231f64bd05',   //请求用户id（我）
    'token' => '',                              //cookie中的auth
    'device_id' => '1536978978521',             //这个不太清楚是啥
    'src' => 'web',                             //来源
    'followee' => ''                            //申请关注人id
);
//关注人列表参数
$userList = array(
    "uid" => "58a15cc70ce463005644171a",       //当前用户id（大佬）
    "currentUid" => "59bf3ba9518825231f64bd05",//请求用户id（我）
    "src" => "web",                            //来源
    "before" => ''                             //关注时间,每次返回这个时间之后的列表
);
$followUrl = 'https://follow-api-ms.juejin.im/v1/follow';  //关注接口
$userListUrl = 'https://follow-api-ms.juejin.im/v1/getUserFollowerList'; //关注人列表接口
$flag = true;
while ($flag) {
    $data = file_get_contents($userListUrl);
    $followList = json_decode($data, true)['d'];
    if (count($followList) == 0) {
    $flag = false;
    }
    foreach (json_decode($data, true)['d'] as $value) {
    $userList['before'] = $value['updatedAtString'];
    $followData['followee'] = $value['follower']['objectId'];
    $re=file_get_contents($followUrl . "?" . http_build_query($followee));
    if($re['s']!=1){ //关注报错终止，关注上限终止
                echo $re['m'];
                exit;
            }
    }
    $userListUrl = $userListUrl . "?" . http_build_query($userList);
}
