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!
