Question

当用户首次登录时，用户会在单击“注销”按钮时退出。但是如果用户再次登录并尝试在清除浏览器的cookie之前注销，则用户无法注销。 Anyhelp？我正在使用cakephp 2.5.6

public function logout() {
        $this->redirect($this->Auth->logout());
    }

// AppController的

class AppController extends Controller {
         public $components = array(
        'DebugKit.Toolbar',
        'Session',
        'Auth' => array(
            'loginRedirect' => false,
            'logoutRedirect' => array('controller' => 'users', 'action' => 'login'),
            'authError' => 'You must be logged in to view this page.',
            'loginError' => 'Invalid Username or Password entered, please try again.',
            'authenticate' => array(
                'Authenticate.MultiColumn' => array(
                    'fields' => array(
                        'username' => 'email',
                        'password' => 'password'
                    ),
                    'columns' => array('email'),
                    'userModel' => 'User',
                    'scope' => array('User.status' => 1)
                )
            )
        ));

    }

您的问题可能与缓存有关，并且由mod_expires.c中的一行引起。将以下标题添加到您的注销功能（以及以防万一）删除会话和cookie应该可以解决问题。

public function logout() {
    header('pragma: no-cache'); 
    header('Cache-Control: no-cache, must-revalidate');
    $this->response->disableCache();
    $this->Session->delete('Auth.User');
    $this->Session->delete('User');
    $this->Session->destroy();
    $this->Cookie->destroy();
    return $this->redirect($this->Auth->logout());
}

cakephp logout工作不正常
