Zend Framework教程之分发器Zend_Controller_Dispatcher用法详解

本文实例讲述了Zend Framework教程之分发器Zend_Controller_Dispatcher用法。分享给大家供大家参考，具体如下：

分发器的具体实现

Zend Framework的分发器Zend_Controller_Dispatcher设计主要有，如下类和接口组成：

├── Dispatcher
│   ├── Abstract.php
│   ├── Exception.php
│   ├── Interface.php
│   └── Standard.php

Zend_Controller_Dispatcher_Interface

定义了分发器提供的基本和标准功能。

interface Zend_Controller_Dispatcher_Interface{  public function formatControllerName($unformatted);  public function formatModuleName($unformatted);  public function formatActionName($unformatted);  public function isDispatchable(Zend_Controller_Request_Abstract $request);  public function setParam($name, $value);  public function setParams(array $params);  public function getParam($name);  public function getParams();  public function clearParams($name = null);  public function setResponse(Zend_Controller_Response_Abstract $response = null);  public function getResponse();  public function addControllerDirectory($path, $args = null);  public function setControllerDirectory($path);  public function getControllerDirectory();  public function dispatch(Zend_Controller_Request_Abstract $request, Zend_Controller_Response_Abstract $response);  public function isValidModule($module);  public function getDefaultModule();  public function getDefaultControllerName();  public function getDefaultAction();}

Zend_Controller_Dispatcher_Abstract

实现了Zend_Controller_Dispatcher_Interface接口，提供了分发器提供的基本和标准功能的抽象父类。
