Zend Framework:在1.8+应用程序中创建自定义路由的方式和位置？

resources.router.routes.custom.route = /custom/:action/*
resources.router.routes.custom.defaults.controller = index
resources.router.routes.custom.defaults.action = index

protected function _initRoutes()
{
    $frontController = Zend_Controller_Front::getInstance();
    $router = $frontController->getRouter();

    $route = new Zend_Controller_Router_Route(
        'custom/:action/*',
        array(
            'controller' => 'index',
            'action' => 'index'
        )
    );

    $router->addRoute('custom', $route);
}

public function customAction()
{
    $action = $this->_getParam('action');

    // 根据 $action 参数执行相应的操作
}
