Zend Framework教程之分发器教程之分发器Zend_Controller_Dispatcher

用法详解用法详解

主要介绍了Zend Framework教程之分发器Zend_Controller_Dispatcher用法,结合实例形式详细分析了分发器

Zend_Controller_Dispatcher的结构,功能,使用技巧与相关注意事项,需要的朋友可以参考下

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。

<?php

/** Zend_Controller_Dispatcher_Interface */

require_once 'Zend/Controller/Dispatcher/Interface.php';

abstract class Zend_Controller_Dispatcher_Abstract implements Zend_Controller_Dispatcher_Interface

{

protected $_defaultAction = 'index';

protected $_defaultController = 'index';

protected $_defaultModule = 'default';

protected $_frontController;

protected $_invokeParams = array();

protected $_pathDelimiter = '_';

protected $_response = null;

protected $_wordDelimiter = array('-', '.');

public function __construct(array $params = array())

{

$this->setParams($params);

}

public function formatControllerName($unformatted)

{

return ucfirst($this->_formatName($unformatted)) . 'Controller';

}

public function formatActionName($unformatted)

{

$formatted = $this->_formatName($unformatted, true);

return strtolower(substr($formatted, 0, 1)) . substr($formatted, 1) . 'Action';

}

public function _verifyDelimiter($spec)

{

if (is_string($spec)) {

return (array) $spec;

} elseif (is_array($spec)) {

$allStrings = true;

foreach ($spec as $delim) {

if (!is_string($delim)) {

$allStrings = false;

break;

}

if (!$allStrings) {

require_once 'Zend/Controller/Dispatcher/Exception.php';

throw new Zend_Controller_Dispatcher_Exception('Word delimiter array must contain only strings');

}

return $spec;

}

require_once 'Zend/Controller/Dispatcher/Exception.php';

throw new Zend_Controller_Dispatcher_Exception('Invalid word delimiter');

}

public function getWordDelimiter()

{

return $this->_wordDelimiter;

}

public function setWordDelimiter($spec)

{

$spec = $this->_verifyDelimiter($spec);

$this->_wordDelimiter = $spec;

return $this;

}

public function getPathDelimiter()

{

return $this->_pathDelimiter;

}

public function setPathDelimiter($spec)

{

if (!is_string($spec)) {

require_once 'Zend/Controller/Dispatcher/Exception.php';

throw new Zend_Controller_Dispatcher_Exception('Invalid path delimiter');

}

$this->_pathDelimiter = $spec;

return $this;

}

protected function _formatName($unformatted, $isAction = false)

{

// preserve directories

if (!$isAction) {

$segments = explode($this->getPathDelimiter(), $unformatted);

} else {

$segments = (array) $unformatted;

}

foreach ($segments as $key => $segment) {

$segment = str_replace($this->getWordDelimiter(), ' ', strtolower($segment));

$segment = preg_replace('/[^a-z0-9 ]/', '', $segment);

$segments[$key] = str_replace(' ', '', ucwords($segment));

}

return implode('_', $segments);

}

public function getFrontController()

{

if (null === $this->_frontController) {

require_once 'Zend/Controller/Front.php';

$this->_frontController = Zend_Controller_Front::getInstance();

}

return $this->_frontController;

}

public function setFrontController(Zend_Controller_Front $controller)

{

$this->_frontController = $controller;

return $this;

}

public function setParam($name, $value)

{

$name = (string) $name;

$this->_invokeParams[$name] = $value;

return $this;

}

public function setParams(array $params)

{
