如何检查控制器插件preDispatch中是否存在操作


How check if action exsist in Controller Plugin preDispatch

我有两个模块(默认和移动)移动模块是jquery-mobile中重写的默认门户,但控制器和操作要少得多!我想写一个控制器插件,检查移动模块中是否存在控制器和操作,如果不存在,我想将移动模块覆盖为默认值。我试试这个:

public function dispatchLoopStartup(Zend_Controller_Request_Abstract $request)
{
    $dispatcher = Zend_Controller_Front::getInstance()->getDispatcher();
    if ($request->getModuleName() == 'mobile') {      
        if (!$dispatcher->isDispatchable($request)) {
            // Controller or action not exists
            $request->setModuleName('default');
        }
    }
    return $request;
}

但是$dispatcher->isDispatchable($request)总是返回true,尽管该操作不存在!:S并且我接收到"动作foo不存在并且没有被困在__call()中"

我该怎么办?感谢

你有没有想过如何从应用程序的任何一端检查zend FM中是否存在控制器/操作?这是代码

    $front = Zend_Controller_Front::getInstance();
    $dispatcher = $front->getDispatcher();
    $test = new Zend_Controller_Request_Http();
    $test->setParams(array(
        'action' => 'index',
        'controller' => 'content',
            )
    );
    if($dispatcher->isDispatchable($test)) {
        echo "yes-its a controller";
        //$this->_forward('about-us', 'content'); // Do whatever you want
    } else {
        echo "NO- its not a Controller";
    }

编辑

像这样检查

$classMethods = get_class_methods($className);
 if(!in_array("__call", $classMethods) &&
 !in_array($this->getActionMethod($request), $classMethods))
 return false;

我建议您通过配置资源管理器、引导程序或前端控制器插件进行静态或动态路由:

Bootstrap.hp:中定义静态路由的示例

public function _initRoutes()
{
    $front = Zend_Controller_Front::getInstance();
    $router = $front->getRouter(); // default Zend MVC routing will be preserved
    // create first route that will point from nonexistent action in mobile module to existing action in default module
    $route = new Zend_Controller_Router_Route_Static(
        'mobile/some-controller/some-action', // specify url to controller and action that dont exist in "mobile" module
        array(
            'module' => 'default', // redirect to "default" module
            'controller' => 'some-controller',
            'action' => 'some-action', // this action exists in "some-controller" in "default" module
        )
    );
    $router->addRoute('mobile-redirect-1', $route); // first param is the name of route, not url, this allows you to override existing routes like default route
    // repeat process for another route
}

这将有效地将/mobile/some-controller/some-action的请求路由到/default/some-concontroller/some-action

某些控制器一些操作应替换为正确的控制器和操作名称。

我使用的是静态路由,如果你路由到确切的url,这是可以的,但由于大多数应用程序在url中使用额外的参数来进行控制器操作,所以最好使用动态路由
在上面的例子中,只需将路由创建类更改为Zend_Controller_Router_Route,将url更改为"mobile/some-controller/some-action/*",每个请求都将动态路由,就像例子中一样:

/mobile/some-contoller/some-action/param1/55/param2/66 
will point to 
/default/some-controller/some-action/param1/55/param2/66
