It is very necessary to make so that Yii2 using the class \ yii \ redis \ Cache does not hash the names of the keys.

// prefix:keyname1 -> 0e46d28d5fb7676bffd12253c26aec56 Yii::$app->cache->set( 'prefix:keyname1', 'key-value-1, 60 * 60 * 24 ); // keyname2 -> keyname2 Yii::$app->cache->set( 'keyname2', 'key-value-2, 60 * 60 * 24 );

The essence of the problem lies in the fact that if the name of the key contains the characters ':', '@', etc. - the class \ yii \ redis \ Cache will hash these key names with the md5 algorithm ... How can I force \ yii \ redis \ Cache not to do this?

You must overload the buildKey method of the Cache class.

For example, like this (for the basic template).

  1. Create the CustomRedisCache class in the components folder:

     <?php namespace app\components; class CustomRedisCache extends \yii\redis\Cache { public function buildKey($key) { return $key; // оставляем ключ как есть } }

  2. In the configuration file, use this class instead of \yii\redis\Cache :

     'components' => [ 'cache' => [ 'class' => 'app\components\CustomRedisCache', ],
