Cookie 是网络工作方式的必要组成部分。网站使用 cookie 来跟踪用户并启用用户特定的功能。因此，在本文中，我们将向大家展示如何在 Magento 2 中从 cookie 中获取和设置数据。

创建类以管理 cookie

第一步是在 app/code/Magentest/Helper 中设置一个 ExampleCookie.php 类。ExampleCookie.php 包含以下内容：

<?php
namespace Magenest\ManagerCookie\Helper;

use Magento\Framework\Session\SessionManagerInterface;

class ExampleCookie {

   protected $cookieManager;
   protected $cookieMetadataFactory;

   public function __construct(
       \Magento\Framework\Stdlib\CookieManagerInterface $cookieManager,
       \Magento\Framework\Stdlib\Cookie\CookieMetadataFactory $cookieMetadataFactory
       )
   {
       $this->cookieManager = $cookieManager;
       $this->cookieMetadataFactory = $cookieMetadataFactory;
    }

   /**
    * get cookie by name
    */
   public function getCookie($cookieName) {
       return $this->cookieManager->getCookie($cookieName);

   }

   /**
    * set public cookie
    */
   public function setPublicCookie($cookieName, $value) {

   $metadata = $this->cookieMetadataFactory
       ->createPublicCookieMetadata()
       ->setDuration(86400) // Cookie will expire after one day (86400 seconds)
       ->setSecure(true) //the cookie is only available under HTTPS
       ->setPath('/subfolder')// The cookie will be available to all pages and subdirectories within the /subfolder path
       ->setHttpOnly(false); // cookies can be accessed by JS
  
   $this->_cookieManager->setPublicCookie(
       $cookieName,
       $value,
       $metadata
   );
}
   
   /**
    * set sensitive cookie
    */
 public function set Sensitive Cookie($cookieName, $value) {

   $metadata = $this->cookieMetadataFactory
       ->createSensitiveCookieMetadata()
       ->setPath('')// for global
       ->setDomain('.example.com');// cookie will be available for www.example.com, example.com and will not be available for anotherexample.com

   $this->_cookieManager->setSensitiveCookie(
       $cookieName,
       $value,
       $metadata
   );
}

}

关于在 Magento 中设置 cookie，首先，你们需要记住，我们在 Magento 中有两种类型的 cookie。它们是公共和敏感 cookie：

公共 cookie可以通过 JS 访问。默认情况下，这些 cookie 的 HttpOnly 将设置为 false。
敏感的cookies不能被客户端的JS访问，它只能在你的服务器上访问。对于这些 cookie，HttpOnly 将始终设置为 true。

设置 cookie 时，您设置了原始 cookie 数据和一些元数据。此元数据包括cookie 的有效路径、cookie 过期时间的Duration等。

在 Javascript 中使用 cookie

在 javascript 中，您只需要包含jquery/jquery.cookie即可使用 cookie

<script type="text/javascript">
   require([
       'jquery',
       'jquery/jquery.cookie'
   ], function ($) {
       $(document).ready(function () {

           var simple_cookie = $.cookie('name_cookie'); // Get Cookie Value, note: You can only get a cookie if it is public
           if(!simple_cookie) {
               $.cookie('name_cookie', 'value of cookie', {expires: 86400}); // Set Cookie with metadata (note the cookies set here are public)
           }else {
               console.log(simple_cookie);
           }
       });
</script>
