CakePHP3 ログイン後のURLを固定する

More than 3 years have passed since last update.

CakePHP3で、ログイン後のURLを指定する場合、
Authコンポーネントを使って以下のように書きますね。

src/Controller/AppController.php
public function initialize()
{
    parent::initialize();
    $this->loadComponent('Auth', [
        'authorize' => 'Controller',
        'authenticate' => [
            'Form' => [
                'fields' => [
                    'username' => 'email',
                    'password' => 'password'
                ]
            ]
        ],
        'unauthorizedRedirect' => [
            'controller' => 'Users',
            'action' => 'login'
        ],
        'loginRedirect' => [
            'controller' => 'Articles',
            'action' => 'index'
        ],
        'logoutRedirect' => [
            'controller' => 'Users',
            'action' => 'login'
        ],
        'authError' => __('You need Logged In.')
    ]);
}

この記述だと、未ログイン状態で例えば
http://sample.com/comments
にアクセスすると
http://sample.com/users/login
にリダイレクトされて、ログインに成功すると
http://sample.com/comments
に戻されます。

アクセスしようとしたURLに戻してくれるので便利といえば便利なのですが、ログイン後のURLを固定したい場合もあるでしょう。

固定したい場合は、sessionからAuth.redirectを消します。

src/Controller/UsersController.php
public function login()
{
    if ($this->request->is('post')) {
        $user = $this->Auth->identify();
        if ($user) {
            $this->Auth->setUser($user);
            $this->Flash->success(__('Log In Success.'));
            $this->request->session()->delete('Auth.redirect');
            return $this->redirect($this->Auth->redirectUrl());
        }
        $this->Flash->error(__('Invalid username or password, try again'));
    }
}

これで、実現できました。
