Yii2 Memcache Cross-platform interaction values cannot be unified

1 First load in configuration file

web\basic\config\web.php ...    ' components ' = = [        ' request ' = = [            //!!! Insert a secret key in the following (if it's empty)-This is Requi Red by Cookie validation '            cookievalidationkey ' = ' Zhaoyang ',        ],        ' mecache ' + = [            ' class ' = ' Yii\caching\memcache ',            ' usememcached ' =>0,            ' servers ' = =                [                    ' host ' = ' localhost ',                    ' Port ' = = 11211,                ]            ],        ],        ' user ' = [            ' identityclass ' = ' app\models\user ',            ' Enableautologin ' = True,        ],............

2 Calling Memcache

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

It's possible to use it in general, no problem at all.

But I memcache the problem with the Java side.

Java writes memcache, I can't get it.

PHP writes the memcache, Java can't get

3 workaround

Web\basic\vendor\yiisoft\yii2\caching\cache.php//overrides 2 methods, both read and write call this method public function MySet ($key, $value, $duration = 0, $ Dependency = null) {    return $this->setvalue ($key, $value, $duration);} Public Function Myget ($key) {    return $this->getvalue ($key);}

The following explains why, in short, the program is encrypted, remove the encryption layer, PHP Java read and write unified on the line

4 analysis

① $mecache = Yii:: $app->mecache;

②\basic\vendor\yiisoft\yii2\caching\memcache.php

③class MemCache extends Cache is a self-cache \basic\vendor\yiisoft\yii2\caching\cache.php

④ View the original Yii2 set and get are encrypted

    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 && Amp        $this->serializer!== false) {$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 the above method to add two non-encrypted direct read and write memcache problem solved
