配置main-local.php

[
    'components' => [
        'cache' => [
            'class' => 'yii\caching\MemCache',
            'servers' => [
                [
                    'host' => '127.0.0.1',
                    'port' => 11211,
                    'weight' => 60,
                ]
            ],
        ],
    ],
]

然后你可以用：

Yii::$app->cache->set($key,$value); //设置
Yii::$app->cache->get($key);        //获取

谢谢，没问题给个最佳答案，哈哈
