嗯,在我看来,
你应该为 web 模块编写一个前端控制器插件,并且这样做,当你需要另一个插件时,你可以很容易地这样做。
前端控制器插件应该是这样的:
class My_Controller_Plugin_Web extends My_Controller_Plugin_Abstract implements My_Controller_Plugin_Interface
{
public function init()
{
// If user is not logged in - send him to login page
if(!Zend_Auth::getInstance()->hasIdentity()) {
// Do something
return false;
} else {
// You then take the domain name
$domainName = $this->_request->getParam( 'domainName', null );
// Retrieve the module name from the database
$moduleName = Module_fetcher::getModuleName( $domainName );
// And set the module name of the request
$this->_request->setModuleName( $moduleName );
if(!$this->_request->isDispatched()) {
// Good place to alter the route of the request further
// the way you want, if you want
$this->_request->setControllerName( $someController );
$this->_request->setActionName( $someAction );
$this->setLayout( $someLayout );
}
}
}
/**
* Set up layout
*/
public function setLayout( $layout )
{
$layout = Zend_Layout::getMvcInstance();
$layout->setLayout( $layout );
}
}
My_Controller_Plugin_Abstract 不是实际的抽象,而是您的控制器插件扩展的,看起来像这样:
class My_Controller_Plugin_Abstract
{
protected $_request;
public function __construct($request)
{
$this->setRequest($request);
$this->init();
}
private function setRequest($request)
{
$this->_request = $request;
}
}
最后是前端控制器插件本身,它决定你应该执行哪个特定的前端控制器插件。
require_once 'Zend/Controller/Plugin/Abstract.php';
require_once 'Zend/Locale.php';
require_once 'Zend/Translate.php';
class My_Controller_Plugin extends Zend_Controller_Plugin_Abstract
{
/**
* before dispatch set up module/controller/action
*
* @param Zend_Controller_Request_Abstract $request
*/
public function routeShutdown(Zend_Controller_Request_Abstract $request)
{
// Make sure you get something
if(is_null($this->_request->getModuleName())) $this->_request->setModuleName('web');
// You should use zend - to camelCase convertor when doing things like this
$zendFilter = new Zend_Filter_Word_SeparatorToCamelCase('-');
$pluginClass = 'My_Controller_Plugin_'
. $zendFilter->filter($this->_request->getModuleName());
// Check if it exists
if(!class_exists($pluginClass)) {
throw new Exception('The front controller plugin class "'
. $pluginClass. ' does not exist');
}
Check if it is written correctly
if(!in_array('My_Controller_Plugin_Interface', class_implements($pluginClass))) {
throw new Exception('The front controller plugin class "'
. $pluginClass.'" must implement My_Controller_Plugin_Interface');
}
// If all is well instantiate it , and you will call the construct of the
// quasi - abstract , which will then call the init method of your
// My_Plugin_Controller_Web :)
$specificController = new $pluginClass($this->_request);
}
}
如果您从未这样做过,那么现在是时候了。 :)
另外,要将前端控制器插件注册到应用程序,您应该在应用程序配置中编辑 frontController 条目。我给你一个json的例子,如果你需要的话,我相信你可以把它翻译成ini / xml / yaml...
"frontController": {
"moduleDirectory": "APPLICATION_PATH/modules",
"defaultModule": "web",
"modules[]": "",
"layout": "layout",
"layoutPath": "APPLICATION_PATH/layouts/scripts",
// This is the part where you register it!
"plugins": {
"plugin": "My_Controller_Plugin"
}
这可能有点令人困惑,如果需要,请随时要求更详细的解释。
