如何检查用户是否登录cakephp 4应用程序使用cakeedc用户插件？

当用户登录时，我需要更改主题

在Application。php

在AppController。php

public function bootstrap(): void
{
    $this->addPlugin('BootstrapUI');
    // Call parent to load bootstrap from files.
    parent::bootstrap();
    $this->addPlugin('CakeDC/Users', ['routes' => true, 'bootstrap' => true]);
    //$this->addPlugin(\CakeDC\Users\Plugin::class);
    Configure::write('Users.config', ['users']);
}

这个错误

public function beforeFilter(EventInterface  $event)
    {
        parent::beforeFilter($event);
           $user = $this->Authentication->identify();
        if ($user) {    
              $this->viewBuilder()->setlayout( 'CakeLte.default' );
        }
}

###假设你已经在你的应用程序中正确配置了认证组件，你可以像下面这样检查用户是否连接:

以防万一，这是对您有用的代码示例。

if($this->Authentication->getIdentity()) {
  // user logged
} else {
  // user not logged
}

在你的控制器中:

在你看来:

$this->Authentication->getIdentity();
// Access to a field
$this->Authentication->getIdentity()->username;
// Access to a method of the entity
$this->Authentication->getIdentity()->isAdmin();

我承认这是很难找到它的文档看起来像是放弃了一些特性。

$this->request->getAttribute('identity')
// Access to a field
$this->request->getAttribute('identity')->username;
// Access to a method of the entity
$this->request->getAttribute('identity')->getOriginalData()->isAdmin();
