Magento自定义路由器丢失的布局对象

本文介绍了Magento自定义路由器丢失的布局对象的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

似乎一切都已正确配置，我可以得到想要的输出，但我宁愿不要直接从控制器回显布局对象:

It seems like everything is being properly configured and I can get the output that I want but I would prefer not echoing the layout object directly from my controller:

我正在与之合作 config.xml

Here is what Im working with config.xml

<config> <modules> <ALS_Bestselling> <version>0.1.0</version> </ALS_Bestselling> </modules> <global> <models> <bestselling> <class>ALS_Bestselling_Model</class> </bestselling> </models> <blocks> <bestselling> <class>ALS_Bestselling_Block</class> </bestselling> </blocks> <helpers> <bestselling> <class>ALS_Bestselling_Helper</class> </bestselling> </helpers> </global> <frontend> <layout> <updates> <als_bestselling> <file>bestselling.xml</file> </als_bestselling> </updates> </layout> </frontend> <default> <web> <routers> <bestselling_router> <area>frontend</area> <class>ALS_Bestselling_Controller_Router</class> </bestselling_router> </routers> </web> <shorturls> </shorturls> </default> </config>

和

#File: Controller/Router.php <?php class ALS_Bestselling_Controller_Router extends Mage_Core_Controller_Varien_Router_Abstract { private static $_module = 'bestsellers'; private static $_realModule = 'ALS_Bestselling'; private static $_controller = 'index'; private static $_controllerClass = 'ALS_Bestselling_Controller_Index'; private static $_action = 'view'; public function initControllerRouters($observer) { $front = $observer->getEvent()->getFront(); $front->addRouter('bestselling', $this); } public function collectRoutes() { // nothing to do here } public function match(Zend_Controller_Request_Http $request) { $this->_request = $request; $front = $this->getFront(); $identifier = trim($request->getPathInfo(), '/'); if(!substr($identifier,0,strlen('bestsellers')) == 'bestsellers'){ return false; }else{ //$rewrite = Mage::getModel('core/url_rewrite'); $route_params = str_replace ( "bestsellers/" , "" , $identifier ); $rewrite = Mage::getModel('core/url_rewrite'); $rewrite->setStoreId(1); $rewrite->loadByRequestPath($route_params); $category_route = $rewrite->getIdPath(); //If no route exists for category send to a different router if(!$category_route != ""){ return false; }//Otherwise send the parameters to the request else{ $id = str_replace ( "category/" , "" , $category_route ); $this->_request->setParam('id',$id); } $this->_setRequestRoute(); $this->_dispatch(); return true; } } protected function _setRequestRoute() { $this->_request->setModuleName(self::$_module); $this->_request->setControllerName(self::$_controller); $this->_request->setActionName(self::$_action); $this->_request->setControllerModule(self::$_realModule); } protected function _dispatch() { $this->_request->setDispatched(true); $controller = Mage::getControllerInstance(self::$_controllerClass, $this->_request, $this->_response); $controller->dispatch(self::$_action); } }

和

File: Controller/Index.php class ALS_Bestselling_Controller_Index extends Mage_Core_Controller_Front_Action{ public function viewAction(){ $layout = Mage::app()->getLayout(); $layout->generateXml()->generateBlocks(); $render = $layout->getBlock('root')->toHtml(); echo $render; } }

先前的作品，但以下作品:

The previous works but the following:

$update = $this->getLayout()->getUpdate(); $update->addHandle('default'); $this->renderLayout();

在非对象上引发错误调用成员函数appendBody().

throws an error Call to a member function appendBody() on a non-object.

这是我应该做的事情吗，还是食谱中缺少一些东西?

Is this how I am suppose to do this or is there something missing from the recipe?

推荐答案

自定义路由类位于大多数开发人员使用Magento的边缘-标准方法是设置具有bestselling 前名的标准模块控制器，或以非SEO友好的方式创建功能，然后创建重写实体/对象以对其进行SEO验证. .

Custom routing classes are on the fringe of what most developers do with Magento — the standard approach would be to setup a standard module controller with a frontname of bestselling, or create your feature in a non-seo friendly way and then create a rewrite entity/object to SEO-ify it.

但是，我对自定义路由对象情有独钟，即使它们背后的最佳社区实践方法很少.没有行号，这听起来像您的例外情况

I, however, have a soft spot for custom routing objects, even if there's little in the way of best community practices behind them. Without a line number, it sounds like your exception

在非对象上调用成员函数appendBody()

Call to a member function appendBody() on a non-object

来自以下代码

#File: app/code/core/Mage/Core/Controller/Varien/Action.php $this->getResponse()->appendBody($output);

给出getResponse

public function getResponse() { return $this->_response; }

听起来您的控制器对象没有设置正确的响应对象.

It sounds like your controller object doesn't have a proper response object set.

查看您的控制器实例化代码

Looking at your controller instantiation code

$controller = Mage::getControllerInstance(self::$_controllerClass, $this->_request, $this->_response);

您引用的是$this->_response属性-但是您的路由器类和抽象路由器类没有此属性.根据您发布的内容无法说出来，但这可能是您的问题.看看标准路由器的match方法是如何做到的.

You're referencing a $this->_response property — but your router class and the abstract router class don't have this property. It's impossible to say based on what you've posted, but this is probably your problem. Take a look at how the standard router's match method does it.

#File: app/code/core/Mage/Core/Controller/Varien/Router/Standard.php //... $controllerInstance = Mage::getControllerInstance($controllerClassName, $request, $front->getResponse());

因此，使用前端控制器对象获取响应对象，并将其传递到getCongrollerInstance工厂方法中，您应该会很好(或至少进入下一个问题)

So, use the front-controller object to grab the response object, pass that into the getCongrollerInstance factory method, and you should be good to go (or at least onto the next problem)
