Question

我正在使用Cakephp，当我从另一个Controller调用方法时，会出现会话错误。

错误 public interface IndexRepository extends CrudRepository<Index, Long> { Index findFirstByOrderByIdAsc(); }

控制器酒店

Error: Call to a member function read() on a non-object

控制器报告方法

App::import('Controller', 'Reports');
$Report = new ReportsController;
$Report->hotelsActivity($cabecera, $data, "Actividad Hotels Report");

标头appController

function hotelsActivity($cabecera, $data, $nombre){
  $this->layout = false;
  $this->autoRender = false;
  $size = parent::excel($cabecera, $data, $nombre);

  $this->set('filesize',CakeNumber::toReadableSize($size));
  $this->set('counter',count($data));

  $this->render('new_reports');
}

Line on在父控制器中获取错误

App::uses('Controller', 'Controller');

class AppController extends Controller {
    public $components = array(
      'Session'
    );

    public $helpers = array(
        'Session'

Answer 1

请试试这个：

将组件添加到控制器

public $components = array('Session');

在你的行动中：

$session = $this->request->session();
$session->read('auth_user.User.user_name');

Answer 2

在app控制器中定义sessionhelper：

class AppController extends Controller {

public $components = array(
    'Session'
);

public $helpers = array(
    'Session'
);
}

然后试一试：

$session = $this->request->session();
$session->read('auth_user.User.user_name');

当我调用另一个Controller时，Cakephp在会话中的非对象上读取（）
