PHP - Manual: Yaf_Plugin_Abstract

Plugins 可以让你轻松地定制和扩展框架
插件(Plugins)是一个类。 基于组件定义的类会有所变化 -- 你可能需要去实现这些接口。 但实际上,该插件(Plugin)本身就是一个类。
一个插件(plugin)会被Yaf_Dispatcher::registerPlugin()加载到Yaf框架中, 在框架注册(registerd)后,插件(plugin)类中定义方法将会在恰当的时间被该接口执行。
示例 #1 Plugin example
<?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 hoook
in this hook user can do loging 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();
?>
以上例程的输出类似于:
string(13) "routerStartup" string(14) "routerShutdown" string(19) "dispatchLoopStartup" string(11) "preDispatch" string(12) "postDispatch" string(20) "dispatchLoopShutdown"
All the methods which the plugin implemented according to this interface, will be called at the proper time automatically.
