捣蛋phpwind控制器注入

在PwBaseController 　里面，会有这个方法的存在

/**
	 * action Hook 注册
	 *
	 * @param string $registerKey 扩展点别名
	 * @param PwBaseHookService $bp
	 * @throws PwException
	 * @return void
	 */
	protected function runHook($registerKey, $bp) {
		if (!$registerKey) return;
		if (!$bp instanceof PwBaseHookService) {
			throw new PwException('class.type.fail',
				array(
					'{parm1}' => 'src.library.base.PwBaseController.runHook',
					'{parm2}' => 'PwBaseHookService',
					'{parm3}' => get_class($bp)));
		}
		if (!$filters = PwHook::getRegistry($registerKey)) return;
		if (!$filters = PwHook::resolveActionHook($filters, $bp)) return;
		$args = func_get_args();
		$_filters = array();
		foreach ($filters as $key => $value) {
			$args[0] = isset($value['method']) ? $value['method'] : '';
			$_filters[] = array('class' => $value['class'], 'args' => $args);
		}
		$this->resolveActionFilter($_filters);
	}

我们先不理这个东西是什么，看它到底是怎样调用的

　　

/**
	 * 发帖
	 */
	public function doaddAction() {

		list($title, $content, $topictype, $subtopictype, $reply_notice, $hide) = $this->getInput(array('atc_title', 'atc_content', 'topictype', 'sub_topictype', 'reply_notice', 'hide'), 'post');
		$pwPost = $this->post;
		$this->runHook('c_post_doadd', $pwPost);

		$postDm = $pwPost->getDm();
		$postDm->setTitle($title)
			->setContent($content)
			->setHide($hide)
			->setReplyNotice($reply_notice);

		//set topic type
		$topictype_id = $subtopictype ? $subtopictype : $topictype;
		$topictype_id && $postDm->setTopictype($topictype_id);

		if (($result = $pwPost->execute($postDm)) !== true) {
			$data = $result->getData();
			$data && $this->addMessage($data, 'data');
			$this->showError($result->getError());
		}
		$tid = $pwPost->getNewId();

		$this->showMessage('success', 'bbs/read/run/?tid=' . $tid . '&fid=' . $pwPost->forum->fid, true);
	}

　　

$this->runHook('c_post_doadd', $pwPost);

之前发帖的时候发现页面有添加话题的内容，但是在控制器入面却没有发现有这种逻辑的操作，后来才知道是通过注入去操作的，我们看看数据库入面的纪录

再看看它们是怎样定义的

/**

 */
class PwPostDoTagInjector extends PwBaseHookInjector {

	public function doadd() {
		$tagNames = (array)$this->getInput('tagnames', 'post');
		if (!is_array($tagNames) || !count($tagNames)) return;
		Wind::import('SRV:forum.srv.post.do.PwPostDoTag');
		return new PwPostDoTag($this->bp,$tagNames);
	}

	public function domodify() {
		$tagNames = (array)$this->getInput('tagnames', 'post');
		Wind::import('SRV:forum.srv.post.do.PwPostDoTag');
		return new PwPostDoTag($this->bp,$tagNames);
	}
}

　　

doadd　这个方法就算添加标签的

它的父类是什么玩意

<?php
defined('WEKIT_VERSION') || exit('Forbidden');

Wind::import('WIND:filter.WindActionFilter');

	}

	/* (non-PHPdoc)

	public function postHandle() {}

}
?>

原来是继承了过滤器，呵呵，所以这个比较强大啊，可以这样用

我们在看看上面控制器的这个方法　resolveActionFilter

/**
	 * action过滤链策略部署
	 *
	 * @example <pre>
	 *          $filters = array(array('expression'=>'', 'class'=>'',
	 *          args=array()));
	 *          </pre>
	 * @param array $filters
	 * @return void
	 */
	protected function resolveActionFilter($filters) {
		if (!$filters) return;
		$chain = WindFactory::createInstance('WindHandlerInterceptorChain');
		$args = array($this->getForward(), $this->getErrorMessage(), null);
		foreach ((array) $filters as $value) {
			$chain->addInterceptors(
				WindFactory::createInstance(Wind::import($value['class']),
					(empty($value['args']) ? $args : array_merge($args, array($value['args'])))));
		}
		$chain->getHandler()->handle();
	}

　　流程是这样的，先建立过滤链　，把过滤器一一添加实例化，哈哈，跟我们之前的没什么区别

　　但是事情还没有结速

　　

class PwPostDoTag extends PwPostDoBase {

	private $loginUser;
	private $defaultType = 'threads';
	private $tagNames = array();
	private $typeId = '';

	public function __construct(PwPost $pwpost,$tagNames) {
		$this->loginUser = $pwpost->user;

			$dm->setName($v);
			if(($return = $dm->beforeAdd()) instanceof PwError) return $return;
		}
		if ($count > 5) {
			return new PwError("Tag:tagnum.exceed");
		}
		if ($count && $this->loginUser->getPermission('tag_allow_add') < 1) {

		return true;
	}

	 * Enter description here ...
	 *
	 * @return PwTagService
	 */
	protected function _getService() {
		return Wekit::load('tag.srv.PwTagService');
	}
}

　　那么　addThread　是在什么时候调用的呢，又是怎样调用的呢　看这里

　　

/**
	 * @see PwPostAction.afterRun
	 */
	public function afterRun() {
		$this->runDo('addThread', $this->tid);
	}

　　这个类是　PwTopicPost　也正是我们在控制器里面刚刚实例化的　，我们断点调式下看看　

　　关键在这里

　　

/* (non-PHPdoc)
	 * @see WindHandlerInterceptor::preHandle()
	 */
	public function preHandle() {
		if (!method_exists($this, $this->callback)) return;
		$injector = call_user_func_array(array($this, $this->callback), $this->args);
		if ($injector) $this->bp->appendDo($injector);
	}

　　把过滤器又加入到＿do里面，不知道为什么要这样呢

　　$this->bp的值是多少呢

　　

　　　原来是这个pwPost

原来是这样,看到这里基本明白啦

　

基本上发帖中就要牵涉到这里操作了，如果第三方插件要加入的话就要加上服务当中　

话题对应的hook 是 c_post_doadd

而发帖本身的hook是　m_PwTopicPost

来看看它是怎样定义的

　　不同的类有不同的方法，可能就是调用时机不同，责任不同，总之就比较复杂
