php 如何以json格式存储session,而不是默认的内置编码?
折腾了下,即使session_save_handler被自己的类或者方法重写,write与read的出入数据都还是被序列化的,而且被session序列化不是一般的序列化...还是不能解解决memcached保存session数据为json的格式

php 如何以json格式存储session,而不是默认的内置编码?
折腾了下,即使session_save_handler被自己的类或者方法重写,write与read的出入数据都还是被序列化的,而且被session序列化不是一般的序列化...还是不能解解决memcached保存session数据为json的格式
找到了方案:
*/
class Memcached
{
/**
* @var \Memcached
*/
protected $memcached;
/**
* Create new memcached session save handler
* @param \Memcached $memcached
*/
public function __construct(\Memcached $memcached)
{
$this->memcached = $memcached;
}
/**
* Close session
*
* @return boolean
*/
public function close()
{
return true;
}
/**
* Destroy session
*
* @param string $id
* @return boolean
*/
public function destroy($id)
{
return $this->memcached->delete("sessions/{$id}");
}
/**
* Garbage collect. Memcache handles this with expiration times.
*
* @param int $maxlifetime
* @return boolean Always true
*/
public function gc($maxlifetime)
{
// let memcached handle this with expiration time
return true;
}
/**
* Open session
*
* @param string $savePath
* @param string $name
* @return boolean
*/
public function open($savePath, $name)
{
// Note: session save path is not used
$this->sessionName = $name;
$this->lifetime = ini_get('session.gc_maxlifetime');
return true;
}
/**
* Read session data
*
* @param string $id
* @return string
*/
public function read($id)
{
$_SESSION = json_decode($this->memcached->get("sessions/{$id}"), true);
if (isset($_SESSION) && !empty($_SESSION) && $_SESSION != null)
{
return session_encode();
}
return '';
}
/**
* Write session data
*
* @param string $id
* @param string $data
* @return boolean
*/
public function write($id, $data)
{
// note: $data is not used as it has already been serialised by PHP,
// so we use $_SESSION which is an unserialised version of $data.
return $this->memcached->set("sessions/{$id}", json_encode($_SESSION),
$this->lifetime);
}
}
可以考虑下写库
