yii2 redis使用

$redis = Yii::$app->redis;$keys = ‘dll_mb_examine‘;//定义键名$list = $redis->get($keys);//取key值if(empty($list)){    $data=Examine::getMobileExamine($userInfo[‘userId‘]);    if(empty($data)){        return $this->redirect([‘/frontend/default/nomsg‘,‘msg‘=>‘暂无数据‘,‘title‘=>‘审批中心‘]);    }    $redis->set($keys,serialize($data));//存数据    $redis->expire($keys,3600*5);//缓存时间5秒}

$data=unserialize($list);$spdata=Config::getConfig(‘shenpileixing‘);foreach($data as $key=>$val){

//编辑数据的时候更新redis缓存$key=Yii::$app->params[‘cache_key‘][‘cyj_info‘].$data[‘earnestId‘];if(!empty($key)){    Yii::$app->cache->delete($key);}

web.php文件里引入redis

    ‘components‘ => [        ‘request‘ => [            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation            ‘cookieValidationKey‘ => ‘pQwkcmQwaDnwv2kQIEpshK2XCYfAilIf‘,        ],        ‘assetManager‘ => [            ‘linkAssets‘ => true,        ],        ‘cache‘ => [//            ‘class‘ => ‘yii\caching\FileCache‘,            ‘class‘ => ‘yii\redis\Cache‘,        ],        ‘redis‘ => [            ‘class‘ => ‘yii\redis\Connection‘,            ‘hostname‘ => ‘192.168.0.227‘,            ‘port‘ => 6379,            ‘database‘ => 0,        ],

yiisoft/extensions.php 尾部追加：

‘yiisoft/yii2-redis‘ =>    array (        ‘name‘ => ‘yiisoft/yii2-redis‘,        ‘version‘ => ‘2.2.0.0‘,        ‘alias‘ =>            array (                ‘@yii/redis‘ => $vendorDir . ‘/yiisoft/yii2-redis‘,            ),    ),
