为CakePHP中的每个URL添加前缀

Router::prefix('admin', function ($routes) {
    // 在这里定义所有带有'admin'前缀的路由
    $routes->connect('/users', ['controller' => 'Users', 'action' => 'index']);
    $routes->connect('/users/:action/*', ['controller' => 'Users']);
});

public function beforeFilter(Event $event)
{
    $this->Auth->allow(['login', 'register']);
}

echo $this->Form->create(null, ['url' => ['prefix' => 'admin', 'controller' => 'Users', 'action' => 'login']]);
