这些 ZF 事件按什么顺序运行？

Question

这是一个 Zend 框架问题。

如果我有一个控制器、一个动作助手和一个插件，它们的事件发生的顺序是什么？下面我按照我认为它们发生的顺序列出了我感兴趣的事件。顺序正确吗？

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

4. 插件，preDispatch()

5. 动作助手，init()

6. 动作助手，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()

我突然想到，对于 Action Helper 和 Controller，这对 init() 方法可能会连续运行，然后是一对 preDispatch() 方法，但我认为这不是案例。

感谢您的帮助！

有趣的问题。我认为你是对的，除了 7 和 6 应该是相反的。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

希望这会有所帮助。
