Yii2中如何使用CHttpCookie

Question

我有下面的代码

use yii\web\CHttpCookie;

$user_identifier = md5(rand()); 
$cookie = new CHttpCookie('user_identifier', $user_identifier);
$cookie->expire = time() + (60*60*24*365*5); 

但是输出错误，请告诉我如何使用HttpCookie

Class 'yii\web\CHttpCookie' not found

Answer 1

Yii2 中没有 C 前缀的类。 Yii2 中的等价物是：

// get the cookie collection (yii\web\CookieCollection) from the "response" component
$cookies = Yii::$app->response->cookies;

// add a new cookie to the response to be sent
$cookies->add(new \yii\web\Cookie([
    'name' => 'user_identifier',
    'value' => md5(rand()),
    'expire' => time() + 60 * 60 * 24 * 365 * 5,
]));

// remove a cookie
$cookies->remove('user_identifier');
// equivalent to the following
unset($cookies['user_identifier']);

在"Setting Cookies" 部分的"Setting Cookies" 部分的官方文档中对此进行了介绍。
