当我尝试打印$this->Session->read('Config')时，它没有打印任何内容。
我使用cakephp 2.5.3
我从网上搜索，阅读了许多博客，帖子和评论，试图解决它，但我的问题仍然存在。虽然$this->Session->setFlash()工作正常，但其他会话值不工作。
App::uses('Controller', 'Controller');
class AppController extends Controller {
var $components = array('Session','RequestHandler');
public function beforeFilter() {
parent::beforeFilter();
debug($this->Session->read('Config'));//null
debug($this->Session->read('Config.userAgent'));//null
debug($this->request->clientIp());// ::1
}
}
please check that at the time of login you create a session or not.
即$this->Session->write('变量名'，'变量值')。如果您不这样做，您将通过您的代码得到null。同样的代码给我的信息登录用户在我的系统。所以确保你已经创建了一个会话，在登录的时候用一些变量名和值的组合。请看看这个:-
public function login() {
if ($this->request->is('post') || $this->request->is('put')) {
$user_detail = $this->User->find('first',array('conditions'=>array('username'=>$this->request->data['User']['username'], 'password'=>$this->Auth->password($this->request->data['User']['password'])),'recursive'=> -1,'fields'=>array('deleted'))); // gettin user details
if(isset($user_detail) && !empty($user_detail)){
if($user_detail['User']['deleted']== '0'){
if ($this->Auth->login()) {// checking user is authorize for login or not?
$this->Session->write('user_role', $this->Auth->user('role_id'));// if yes create session variable with the given variable name and value.
$is_incharge = $this->check_incharge($this->Auth->user('id'));
if ($is_incharge) {
$this->Session->write('is_user_incharge', true);
} else {
$this->Session->write('is_user_incharge', false);
}
$this->redirect($this->Auth->loginRedirect);
} else {
$this->Session->setFlash(__('Invalid User name or Password.'));
$this->redirect($this->Auth->logoutRedirect);
}
}else{
$this->Session->setFlash(__('You are deleted.Can not login.'));
$this->redirect($this->Auth->logoutRedirect);
}
}else{
$this->Session->setFlash(__('Invalid User name or Password..'));
$this->redirect($this->Auth->logoutRedirect);
}
}
}
