本文实例讲述了Yii2中cookie用法。分享给大家供大家参考，具体如下：

<?php//设置方法$cookie = new Cookie([ 'name' => 'cookie_monster', 'value' => 'Me want cookie!', 'expire' => time() + 86400 * 365,]);\Yii::$app->getResponse()->getCookies()->add($cookie);//读取方法$value = \Yii::$app->getRequest()->getCookies()->getValue('my_cookie');//给cookie加域名$cookie = new Cookie([ 'name' => 'cookie_monster', 'value' => 'Me want cookie everywhere!', 'expire' => time() + 86400 * 365, 'domain' => '.example.com' // <<<=== HERE]);\Yii::$app->getResponse()->getCookies()->add($cookie);//设置登录cookie$config = [ // ... 'components' => [ // ... 'user' => [ 'class' => 'yii\web\User', 'identityClass' => 'app\models\User', 'enableAutoLogin' => true, 'loginUrl' => '/user/login', 'identityCookie' => [ // <---- here! 'name' => '_identity', 'httpOnly' => true, 'domain' => '.example.com', ], ], 'request' => [ 'cookieValidationKey' => 'your_validation_key' ], 'session' => [ 'cookieParams' => [ 'domain' => '.example.com', 'httpOnly' => true, ], ], ],];//只给批定目录配置cookie$config = [ // ... 'components' => [ // ... 'session' => [ 'name' => 'admin_session', 'cookieParams' => [ 'httpOnly' => true, 'path' => '/admin', ], ], ],];?>
