Yii2.0 Cookie使用方法

Cookie

Yii2的Cookie主要是通过yii\web\Request和yii\web\Response进行操作

• 通过\Yii::$app->response->getCookies()->add()添加Cookie
• 通过\Yii::$app->request->cookies读取Cookie.

① 添加Cookie

<?php//第一种方法$cookie = new \yii\web\Cookie();$cookie -> name = 'smister';        //cookie的名称$cookie -> expire = time() + 3600;   //存活的时间$cookie -> httpOnly = true;   //无法通过js读取cookie$cookie -> value = 'cookieValue';   //cookie的值\Yii::$app->response->getCookies()->add($cookie);//第二种方法$cookie = new \yii\web\Cookie([    ‘name’ => ‘smister’,    ‘expire’ => time() + 3600,    ‘httpOnly ’ => true,    ‘value’ => ‘cookieValue’]);\Yii::$app->response->getCookies()->add($cookie);?>

② 读取Cookie

<?php$cookie = \Yii::$app->request->cookies;//返回一个\yii\web\Cookie对象$cookie->get(‘smister’);//直接返回Cookie的值$cookie->getValue(‘smister’); //$cookie[‘smister’] 其实这样也是可以读取的//判断一个Cookie是否存在$cookie->has(‘smister’);//读取Cookie的总数$cookie->count();//$cookie->getCount();跟count一样?>

③ 删除Cookie

<?php$cookie = Yii::$app->request->cookies->get(‘smister’);//移除一个Cookie对象\Yii::$app->response->getCookies()->remove($cookie);//移除所有Cookie，目前好像不太好使\Yii::$app->response->getCookies()->removeAll();?>

❤[说明]对Cookie进行增删改时调用的response , 对Cookie读取时使用的是Request
