在yii中新增一个用户验证的方法详解(3)

class CAdminAccessControlFilter extends CAccessControlFilter 
{ 
    protected function preFilter($filterChain) 
    { 
        $app=Yii::app(); 
        $request=$app->getRequest(); 
        $user = Yii::app()->controller->module->getComponent('adminUser'); 
        $verb=$request->getRequestType(); 
        $ip=$request->getUserHostAddress(); 

        foreach($this->getRules() as $rule) 
        { 
            if(($allow=$rule->isUserAllowed($user,$filterChain->controller,$filterChain->action,$ip,$verb))>0) // allowed 
                break; 
            else if($allow<0) // denied 
            { 
                $this->accessDenied($user); 
                return false; 
            } 
        } 
        return true; 
    } 
}

再重写CController类的filterAccessController方法
Php代码

复制代码 代码如下:

public function filterAccessControl($filterChain) 
{ 
    $filter = new CAdminAccessControlFilter(); 
    $filter->setRules($this->accessRules()); 
    $filter->filter($filterChain); 
} 
//在这里我们使用自定义的filter类替换了原来的filter

OK,到这里我们就可以在此Controller的accessRules()中指定adminUser的授权了
