yii框架中关于控制器中filter过滤器和外部action的使用

class TestController extends Controller
{
    /**
     * 定义外部的action
     * @return array
     */
    public function actions()
    {
        return array(
            ‘testa‘ => array(
                ‘class‘ => ‘TestAction‘
            )
        );
    }
    public function filters()
    {
        return array(
　　　　　　　　             //‘tes+edit,modify‘ 仅仅edit和modify需要执行过滤
            ‘tes-delete‘  //除了delete外，其他都需要执行过滤
        );
    }
    public function filterTes($filterChain)
    {
        echo "this is a filter...\r\n";
        /*
         * 定义过滤器链，$filterChain让后面的控制器继续执行
         */
        $filterChain->run();
    }

    public function actionTe()
    {
        echo $this->action->id.PHP_EOL;
        Yii::app()->clientScript->registerScriptFile();
        echo "this is test controller...\r\n";
    }
    public function actionDelete()
    {
        echo "this is delete action...\r\n";
    }
}
