cakephp 4 - 身份验证 2 - 未识别时如何显示消息

Question

我在 cakephp4 中使用身份验证 (2) 插件。我已经设置：

        'unauthenticatedRedirect' => '/users/login',

为了重定向需要身份验证的请求。它工作正常。

但我想添加一条消息，例如一条快讯，内容为 "You must be log in to acceess this page"。

有简单的方法吗？

谢谢

尚无具体功能：https://github.com/cakephp/authentication/issues/316

它可以通过许多不同的方式解决，我个人之前通过在扩展身份验证组件中捕获 Authentication\Authenticator\UnauthenticatedException，通过覆盖 \Authentication\Controller\Component\AuthenticationComponent::doIdentityCheck():

来解决这个问题

<?php
// src/Controller/Component/AppAuthenticationComponent.php

/*
load in `AppController::initialize()` via:

$this->loadComponent('Authentication', [
    'className' => \App\Controller\Component\AppAuthenticationComponent::class,
]);
*/

namespace App\Controller\Component;

use Authentication\Authenticator\UnauthenticatedException;
use Authentication\Controller\Component\AuthenticationComponent;
use Cake\Controller\Component\FlashComponent;

/**
 * @property FlashComponent $Flash
 */
class AppAuthenticationComponent extends AuthenticationComponent
{
    public $components = [
        'Flash'
    ];

    protected function doIdentityCheck(): void
    {
        try {
            parent::doIdentityCheck();
        } catch (UnauthenticatedException $exception) {
            $this->Flash->error(__('You must be logged in to access this page.'));

            throw $exception;
        }
    }
}

您也可以在您的应用程序控制器中手动执行此操作，因为您必须禁用插件组件的自动身份检查，并自行执行该检查：

// src/Controller/AppController.php

public function initialize(): void
{
    parent::initialize();

    $this->loadComponent('Authentication.Authentication', [
        'requireIdentity' => false
    ]);
}

public function beforeFilter(EventInterface $event)
{
    parent::beforeFilter($event);

    $action = $this->request->getParam('action');
    if (
        !in_array($action, $this->Authentication->getUnauthenticatedActions(), true) &&
        !$this->Authentication->getIdentity()
    ) {
        $this->Flash->error(__('You must be logged in to access this page.'));

        throw new UnauthenticatedException('No identity found.');
    }
}
