Symfony-MemcachedAdapter :: __ construct()必须是Memcached的实例，给定字符串 [英] Symfony - MemcachedAdapter::__construct() must be an instance of Memcached, string given

问题描述

这很奇怪.我已经使用Memcached设置了缓存，如下所示:

This is rather bizarre. I have set up caching with Memcached as follows:

framework.yaml

framework.yaml

framework:
    cache:
        app: app.memcached_adapter

services.yaml

services.yaml

app.memcached_client:
    class: Memcached
    factory: 'Symfony\Component\Cache\Adapter\MemcachedAdapter::createConnection'
    arguments: [['%app.memcached.dsn.1%', '%app.memcached.dsn.2%']]
    public: true

app.memcached_adapter:
    class: Symfony\Component\Cache\Adapter\MemcachedAdapter
    arguments:
        - '@app.memcached_client'
    public: true

我能够清除终端中的缓存而没有任何错误，但是当我加载网站时，我得到以下信息:

I am able to clear cache in the terminal without any errors, but when I load my site, I get the following:

Type error: Argument 1 passed to Symfony\Component\Cache\Adapter\MemcachedAdapter::__construct() 
must be an instance of Memcached, string given, called in 
/users/me/project/please-dont-mention-the-company/sports/var/cache/lcl/ContainerXqbuh45/srcLclDebugProjectContainer.php 
on line 1029

在查看所生成的容器类时，我发现了这一点:

Upon looking in said generated container class, I found this:

/**
 * Gets the public 'cache.app' shared service.
 *
 * @return \Symfony\Component\Cache\Adapter\TraceableAdapter
 */
protected function getCache_AppService()
{
    return $this->services['cache.app'] = new \Symfony\Component\Cache\Adapter\TraceableAdapter(new \Symfony\Component\Cache\Adapter\MemcachedAdapter('kRTmoLLARw'));
}

我不知道它是如何使用该字符串作为参数生成的，它应该是内存缓存客户端！

I have no idea how it generated with that string as the argument, it should be the memcached client!

有什么想法吗?我可以进行任何检查而不必调试容器类的生成吗?

Any ideas? Anything I can check without having to debug the container class generation?

推荐答案

您尝试过从服务容器中获取CacheAdapter而不是在此处创建新实例的方法: return $this->services['cache.app'] = new \Symfony\Component\Cache\Adapter\TraceableAdapter( new \Symfony\Component\Cache\Adapter\MemcachedAdapter('kRTmoLLARw') // new instance? );

have you tried it to get the CacheAdapter from the Service-Container instead of creating a new Instance here: return $this->services['cache.app'] = new \Symfony\Component\Cache\Adapter\TraceableAdapter( new \Symfony\Component\Cache\Adapter\MemcachedAdapter('kRTmoLLARw') // new instance? );
