yii2 memcache 跨平台交互 键和值不一样

1 首先在配置文件中加载

webasicconfigweb.php
........
    'components' => [
        'request' => [
            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
            'cookieValidationKey' => 'zhaoyang',
        ],
        'mecache' => [
            'class' => 'yiicachingMemCache',
            'useMemcached' =>0, //这里简单说明一下 0是memcache, 1是memcached 两个是php里不同的扩展
            'servers' => [
                [
                    'host' => 'localhost',
                    'port' => 11211,
                ]
            ],
        ],
        'user' => [
            'identityClass' => 'appmodelsUser',
            'enableAutoLogin' => true,
        ],
............

2 调用memcache

　$mecache = Yii::$app->mecache;　
   $mecache->set("key","value", 60);
   $mecache->get("key");

一般这么用是可以的,一点问题都没有

但是我与java 那边的memcache交出了问题

java 写的memcache,我拿不到

php 写的memcache, java拿不到

3 解决方法

webasicvendoryiisoftyii2cachingCache.php
//重写2个方法, 读写都调用这个方法

public function myset($key, $value, $duration = 0, $dependency = null)
{
    return $this->setValue($key, $value, $duration);
}

public function myget($key)
{
    return $this->getValue($key);
}

下面解释为什么这么做, 简单来讲, 程序做了加密, 去掉加密的那一层, php java 都读写统一就行了

4 分析

　　① $mecache = Yii::$app->mecache;

　　② asicvendoryiisoftyii2cachingMemCache.php 

　　③ class MemCache extends Cache  即成自cache    asicvendoryiisoftyii2cachingCache.php 

　　④ 查看原来yii2 的set 和 get 都做了加密处理

    public function get($key)
    {
        $key = $this->buildKey($key);
        $value = $this->getValue($key);
        if ($value === false || $this->serializer === false) {
            return $value;
        } elseif ($this->serializer === null) {
            $value = unserialize($value);
        } else {
            $value = call_user_func($this->serializer[1], $value);
        }
        if (is_array($value) && !($value[1] instanceof Dependency && $value[1]->getHasChanged($this))) {
            return $value[0];
        } else {
            return false;
        }
    }


    public function set($key, $value, $duration = 0, $dependency = null)
    {
        if ($dependency !== null && $this->serializer !== false) {
            $dependency->evaluateDependency($this);
        }
        if ($this->serializer === null) {
            $value = serialize([$value, $dependency]);
        } elseif ($this->serializer !== false) {
            $value = call_user_func($this->serializer[0], [$value, $dependency]);
        }
        $key = $this->buildKey($key);

        return $this->setValue($key, $value, $duration);
    }

　　⑤ 按照上面的方法添加两个没有加密的直接读写 的memcache  问题就解决了
