DoctrineCacheBundle:我不能理解使用redis的文档

As I was looking the documentation in order to figure out how to use it in order to Cache APi results.

I cannot understand how to setup the configuration in order to make it work with either redis or predis.

I tried the following con figuration:

doctrine_cache:
    aliases:
      my_cache:  'redis'

    providers:
        redis:
          host: '%redis_host%'
          port: '%redis_port%'
          aliases:
            - my_cache

But as I was tryint to debug my container with:

php bin/console debug:container doctrine

I got the error:

"host" is an unrecognized Doctrine cache driver.

I also tried the following configuration:

doctrine_cache:
    aliases:
      my_cache:  'redis'

    providers:
        redis:
          type: 'redis'
          host: '%redis_host%'
          port: '%redis_port%'
          aliases:
            - my_cache

With the very same error. Also on documentation is not very clear how to pass the configaration option. Futhermore as said there both redis and predis are natively provided with the bundle.

    First setup configuration for redis.

    doctrine_cache:
        aliases:
            cache: "%cache_provider%"
        providers:
            redis_cache:
                namespace: "%redis_cache_keyspace%"
                redis:
                    host: "%redis_cache_host%"
                    port: "%redis_cache_port%"
           array_cache:
                type: array
    

    Then, set parameters.yml:

    cache_provider: array_cache
    redis_cache_host: localhost
    redis_cache_port: 6379
    redis_cache_keyspace: [your_keyspace]
    

    I created a RedisService:

    <?php
    
    namespace AppBundle\Service;
    
    use Doctrine\Common\Cache\Cache;
    
    class RedisService
    {
        private $cache;
        /**
        * RedisService constructor.
        * @param Cache $cache
        */
        public function __construct(Cache $cache)
        {
            $this->cache = $cache;
        }
    
        public function insert($key, $value, $lifetime = null)
        {
            return $this->cache->save($key, $value, $lifetime);
        }
    
        public function get($key)
        {
            return $this->cache->fetch($key);
        }
    
        public function delete($key)
        {
            return $this->cache->delete($key);
        }
    
    }
    

    Add this lines services.yml

    redis_service:
        class: AppBundle\Service\RedisService
        arguments: ["@doctrine_cache.providers.redis_cache"]
    

    And you can use it everywhere. Sample;

    <?php
    
    namespace AppBundle\Controller;
    
    use Symfony\Bundle\FrameworkBundle\Controller\Controller;
    use Symfony\Component\HttpFoundation\Request;
    use Symfony\Component\HttpFoundation\Response;
    use Symfony\Component\Routing\Annotation\Route;
    
    /**
    * @package AppBundle\Controller
    * @Route("/")
    */
    class RedisApiController extends Controller
    {
    
        /**
        * @return object
        */
        public function getRedisService()
        {
            return $this->get('redis.service');
        }
    
        /**
        * @Route("/insert", name="insert")
        */
        public function insertAction(){
            $this->getRedisService()->insert('website', 'http://mertblog.net', 3600);
        }
    
        /**
        * @Route("/get", name="get")
        */
        public function getAction(){
            $webSite = $this->getRedisService()->get('website');
        }
    
        /**
        * @Route("/delete", name="delete")
        */
        public function deleteAction(){
            $this->getRedisService()->delete('website');
        }
    }
