This article mainly introduces to you the method of implementing single sign-on in Yii2. The editor thinks it is quite good, so I will share it with you now and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.

Modify/common/config/main.php

1. Add the following code to the config header

<?php
// Session 跨域
$host = explode(&#39;.&#39;, $_SERVER["HTTP_HOST"]);
if (count($host) > 2) {
  define('DOMAIN', $host[1] . '.' . $host[2]);
} else {
  define('DOMAIN', $host[0] . '.' . $host[1]);
}

2. Add ## to the components configuration of config #

<?php
&#39;user&#39; => [
  'identityClass' => 'common\models\User',
  'enableAutoLogin' => true,
  'identityCookie' => ['name' => '_identity', 'httpOnly' => true, 'domain' => '.'.DOMAIN],
],
'session' => [
  'cookieParams' => ['domain' => '.'.DOMAIN, 'lifetime' => 0],
  'timeout' => 3600,
],

3. Using

<?php
//设置
Yii::$app->session['var']='value';
//使用
echo Yii::$app->session['var'];
//移除
unset(Yii::$app->session['var']);
