Yaf_Plugin_Abstract 类

(Yaf >=1.0.0)

简介

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

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"
