Plugins 允许轻松地定制和扩展框架。
插件(Plugin)是类。实际定义的类将会基于组件变化——需要实现这些接口,但该插件(Plugin)本身就是一个类。
插件(plugin)通过使用 Yaf_Dispatcher::registerPlugin() 加载到 Yaf 中,在框架注册后,插件根据接口实现的所有方法将会在恰当的时间被调用。
示例 #1 插件示例
<?php
/* bootstrap class should be defined under ./application/Bootstrap.php */
class Bootstrap extends Yaf_Bootstrap_Abstract {
        public function _initPlugin(Yaf_Dispatcher $dispatcher) {
/* register a plugin */
$dispatcher->registerPlugin(new TestPlugin());
        }
   }
/* plugin class should be placed under ./application/plugins/ */
class TestPlugin extends Yaf_Plugin_Abstract {
        public function routerStartup(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
/* 在路由之前执行,这个钩子里,你可以做url重写等功能 */
var_dump("routerStartup");
        }
        public function routerShutdown(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
/* 路由完成后,在这个钩子里,你可以做登陆检测等功能*/
var_dump("routerShutdown");
        }
        public function dispatchLoopStartup(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
var_dump("dispatchLoopStartup");
        }
        public function preDispatch(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
var_dump("preDispatch");
        }
        public function postDispatch(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
var_dump("postDispatch");
        }
        public function dispatchLoopShutdown(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
/* final hook
               in this hook user can do logging or implement layout */
var_dump("dispatchLoopShutdown");
        }
   }
   Class IndexController extends Yaf_Controller_Abstract {
        public function indexAction() {
            return FALSE; //prevent rendering
}
   }
$config = array(
"application" => array(
"directory" => dirname(__FILE__) . "/application/",
       ),
   );
$app = new Yaf_Application($config);
$app->bootstrap()->run();
?>以上示例的输出类似于:
string(13) "routerStartup" string(14) "routerShutdown" string(19) "dispatchLoopStartup" string(11) "preDispatch" string(12) "postDispatch" string(20) "dispatchLoopShutdown"
