无法在 Yii2 中获取 cookie 值

Question

我已经使用以下代码在页面上设置了 cookie：

$newCookie= new \yii\web\Cookie();
$newCookie->name='cookie_name';
$newCookie->value='test value';
$newCookie->expire = time() + 60 * 60 * 24 * 180;
$cookie=Yii::$app->getResponse()->getCookies()->add($newCookie);

但是当我在另一个页面上尝试检查是否设置了 cookie 时，我无法获取 cookie 值：

if(Yii::$app->getResponse()->getCookies()->has('cookie_name')){
    if(Yii::$app->getResponse()->getCookies()->getValue('cookie_name')){
        echo "cookie available";die;
    }
}

谁能告诉我我做错了什么？？？

非常感谢

您应该使用请求组件来读取 cookies :

if(Yii::$app->getRequest()->getCookies()->has('cookie_name')){
}

Both yii\web\Request and yii\web\Response maintain a collection of cookies via the property named cookies. The cookie collection in the former represents the cookies submitted in a request, while the cookie collection in the latter represents the cookies that are to be sent to the user.
