yii2 redis使用

Posted 2020-08-23

$redis = Yii::$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‘,
            ),
    ),
