这些ZF事件以什么顺序运行？

Question

这是一个Zend Framework问题.

如果我有一个控制器,一个动作助手和一个插件,他们的事件发生在什么顺序？下面我按照我认为发生的顺序列出了我感兴趣的事件.订单是否正确？

1. 插件,routeStartup()
2. 插件,routeShutdown()
3. 插件,dispatchLoopStartup()

4. 插件,preDispatch()

5. 动作助手,init()

6. Action Helper,preDispatch()

7. 控制器,init()

8. 控制器,preDispatch()

9. 控制器,postDispatch()

10. 动作助手,postDispatch()

11. 插件,postDispatch()

12. 插件,dispatchLoopShutdown()

在我看来,当涉及Action Helper和Controller时,init()方法对可以连续运行,然后是一对preDispatch()方法,但我不认为是这种情况.

谢谢你的帮助!

有趣的问题.我认为你是正确的,除了7和6应该是对方.为了检查它,我调试了一个ZF应用程序.这是我发现的:

1.  $this->_plugins->routeStartup($this->_request);         #$this is Zend_Controller_Front

    $router->route($this->_request);                        #$router is Zend_Controller_Router_Rewrite, and method route finds a matching route to the current PATH_INFO

2.  $this->_plugins->routeShutdown($this->_request);        #$this is Zend_Controller_Front

3.  $this->_plugins->dispatchLoopStartup($this->_request);  #$this is Zend_Controller_Front

4.  $this->_plugins->preDispatch($this->_request);          #$this is Zend_Controller_Front

5.  $helper->init();    # exectued for helpers by Zend_Controller_Action_HelperBroker
                        # during making an instance of IndexController.
                        # Specifically for Zend_Controller_Action_Helper_ViewRenderer
                        # and Zend_Layout_Controller_Action_Helper_Layout


// IndexControlles has just been instantiated 


6.  $this->init();                        # $this is  IndexController

7.  $this->_helper->notifyPreDispatch();  # $this is  IndexController

8.  $this->preDispatch();                 # $this is  IndexController

    $this->$action();                     # $this is  IndexController (action executed)

9.  $this->postDispatch();                # $this is  IndexController

10. $this->_helper->notifyPostDispatch(); # $this is  IndexController


// Execution of IndexController has just finished


11. $this->_plugins->postDispatch($this->_request);  #$this is Zend_Controller_Front

12. $this->_plugins->dispatchLoopShutdown();         #$this is Zend_Controller_Front 


// after that response is sent

 $this->_response->sendResponse();                   #$this is Zend_Controller_Front

希望这可以帮助.
