authentication - CakePHP 3.2 : Prevent authError showing when user is not logged in

Question

即使用户未登录并尝试打开主页，在被重定向到登录页面后，也会显示 authError。是否有一种优雅的方法来防止这种情况，而无需修改 Auth 组件？这是我加载 Auth 组件的方式(我使用 TinyAuth 作为授权适配器):

$this->loadComponent('Auth', [
                'loginAction' => [
                    'controller' => 'Users',
                    'action' => 'login'
                ],
                'loginRedirect' => [
                   'controller' => 'Home',
                   'action' => 'index'
                ],
                'authError' => 'You dont have permissions for that action',
                'authenticate' => [
                    'Form' => [
                        'fields' => [
                            'username' => 'email',
                            'password' => 'password'
                        ],
                        'scope' => ['Users.active' => true],
                        'contain' => ['Roles']
                    ]
                ],
                'authorize' => [
                    'TinyAuth.Tiny' => [
                        'roleColumn' => 'role_id',
                        'rolesTable' => 'Roles',
                        'multiRole' => true,
                        'pivotTable' => 'roles_users',
                        'superAdminRole' => null,
                        'authorizeByPrefix' => false,
                        'prefixes' => [],
                        'allowUser' => false,
                        'adminPrefix' => null,
                        'autoClearCache' => true
                    ] 
                ]
            ]
        );

根据 CakePHP's documentation您可以通过将 authError 设置为 false 来防止显示错误消息。

Sometimes, you want to display the authorization error only after the user has already logged-in. You can suppress this message by setting its value to boolean false.

这应该禁用错误消息:

if (!$this->Auth->user()) {
    $this->Auth->config('authError', false);
}
