一，操作

//设置$cookie = new CHttpCookie('mycookie','this is my cookie');$cookie->expire = time()+60*60*24*30;  //有限期30天Yii::app()->request->cookies['mycookie']=$cookie;//获取$cookie = Yii::app()->request->getCookies();$test_cookie =  $cookie['mycookie']->value;//删除unset($cookie['mycookie']);

二，注册

   CApplication::registerCoreComponents()

protected function registerCoreComponents(){    $components=array(        'request'=>array(            'class'=>'CHttpRequest',        ),    );    $this->setComponents($components);}

三，源码

   CHttpRequest::getCookies();

class CCookieCollection extends CMap{     protected function getCookies(){        $cookies=array();        if($this->_request->enableCookieValidation){              $sm=Yii::app()->getSecurityManager();    //获得安全管理器组件对象            //遍历cookie数据            foreach($_COOKIE as $name=>$value){                //是字符串 && 经过安全校验后等于原值则通过                if(is_string($value) && ($value=$sm->validateData($value))!==false)                    $cookies[$name]=new CHttpCookie($name,@unserialize($value));            }        }else{            foreach($_COOKIE as $name=>$value)                $cookies[$name]=new CHttpCookie($name,$value);            }            return $cookies;        }    //...}

   CMap

class CMap extends CComponent implements IteratorAggregate,ArrayAccess,Countable{    public function offsetGet($offset){        return $this->itemAt($offset);    }    public function offsetSet($offset,$item){    $this->add($offset,$item);    }    public function offsetUnset($offset){    $this->remove($offset);    }    //....}
