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' => 'yiiwebUser',
      'identityClass' => 'appmodelsUser',
      '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' => [
