yii2怎么查看cookies

设置Cookie

PHP （推荐学习：yii教程）

setcookie("name", "Larry", time()+3600);

Yii2

$cookies = Yii::$app->response->cookies;   $cookies->add(new yiiwebCookie([     'name' => 'name',     'value' => 'Larry',     'expire'=>time()+3600 ]));

创建名为"name"的cookie，赋值为"Larry",并且规定该cookie一小时后失效

expire这是一个UNIX时间戳，如果设置为0，或省略，该Cookie将在浏览器关闭时消失

获取Cookie

PHP

$name=$_COOKIE["user"]

Yii2

$cookies = Yii::$app->request->cookies;//注意此处是request $language = $cookies->get('user', 'defaultName');//获取默认值

检查Cookie

PHP

if(isset($_COOKIE["user"])){ }

Yii2

$cookies = Yii::$app->request->cookies;   if (isset($cookies['user'])){ } if ($cookies->has('user')){ } if (isset($cookies['user'])){ }
