会话codeigniter中的错误

Question

我在CodeIgniter中遇到了一个会话问题，我希望将其作为带有令牌的会话。但是有一个错误如下

致命错误：Call to undefined method CI_Session::set_token()

function __construct()
{
    parent::__construct();
    $this->load->model('appdata','mod');
    $this->load->library('session');

}   

public function token($id_user)
{
    $token="";
    $date_key = date("Y-m-d h:i:s",time());
    $random_key = rand(1,0);
    $usertoken = substr($id_user,2,4);
    $token = $date_key."-".$usertoken."-".$random_key;
    $this->session->set_token('key_token',$token);
    session_start();
    return $token;
}

请帮助我，谢谢

Answer 1

它没有set_token它的set_userdata

public function token($id_user)
{
    $token="";
    $date_key = date("Y-m-d h:i:s",time());
    $random_key = rand(1,0);
    $usertoken = substr($id_user,2,4);
    $token = $date_key."-".$usertoken."-".$random_key;
    $this->session->set_userdata('key_token',$token);
    session_start();
    return $token;
}
