Symfony：以JSON存储会话

Posted 2021-03-28

在我的Symfony应用程序中，我使用NodeJS和socket.io来构建聊天功能并发送实时通知。为此，我使用Redis以JSON格式存储会话，因此可以在javascript中轻松解析。

public function read($session_id) {
    $tmp = $_SESSION;
    $_SESSION = json_decode($this->client->get(self::PREFIX . $session_id), true);

    if (isset($_SESSION) && !empty($_SESSION) && $_SESSION != null) {
        $encoded_data = session_encode();
        $_SESSION = $tmp;

        return $encoded_data;
    }

    return '';
}

public function write($session_id, $session_data) {
    $tmp = $_SESSION;
    session_decode($session_data);
    $decoded_data = $_SESSION;
    $_SESSION = $tmp;

    $this->client->setex(self::PREFIX . $session_id, $this->ttl, json_encode($decoded_data));

    return true;
}

问题是会话未正确编码，尤其是用户信息（身份验证部分）。

Symfony存储会话：

"_sf2_attributes|a:2:{s:18:"_csrf/authenticate";s:43:"Fc3iwpceqYiNmAn1FbUyQyaEPdu7qbI_unu5dBAgaTg";s:14:"_security_main";s:456:"C:74:"Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken":368:{a:3:{i:0;N;i:1;s:4:"main";i:2;s:328:"a:4:{i:0;C:21:"AppBundle\Entity\User":127:{a:5:{i:0;i:52;i:1;s:12:"user123";i:2;s:60:"$2y$13$mgT//whXPFsj7b0XCAWhdeiC2oGZqojiAzky.6sThuN6MI9zALt1.";i:3;i:1;i:4;i:1;}}i:1;b:1;i:2;a:1:{i:0;O:41:"Symfony\Component\Security\Core\Role\Role":1:{s:47:"x00Symfony\Component\Security\Core\Role\Rolex00role";s:9:"ROLE_USER";}}i:3;a:0:{}}";}}";}_sf2_flashes|a:0:{}_sf2_meta|a:3:{s:1:"u";i:1524485577;s:1:"c";i:1524485576;s:1:"l";s:1:"0";}"

JSON编码会话：

"{"_sf2_attributes":{"_csrf\/authenticate":"hvNt4SQIm7IArE57JgHyuVSCLlt4hrw1D-PVC_kBfKA","_security_main":"C:74:\"Symfony\\Component\\Security\\Core\\Authentication\\Token\\UsernamePasswordToken\":368:{a:3:{i:0;N;i:1;s:4:\"main\";i:2;s:328:\"a:4:{i:0;C:21:\"AppBundle\\Entity\\User\":127:{a:5:{i:0;i:52;i:1;s:12:\"user123\";i:2;s:60:\"$2y$13$mgT\/\/whXPFsj7b0XCAWhdeiC2oGZqojiAzky.6sThuN6MI9zALt1.\";i:3;i:1;i:4;i:1;}}i:1;b:1;i:2;a:1:{i:0;O:41:\"Symfony\\Component\\Security\\Core\\Role\\Role\":1:{s:47:\"\u0000Symfony\\Component\\Security\\Core\\Role\\Role\u0000role\";s:9:\"ROLE_USER\";}}i:3;a:0:{}}\";}}"},"_sf2_flashes":[],"_sf2_meta":{"u":1524651793,"c":1524651793,"l":"0"}}"

Symfony不使用php内置存储机制吗？我在这做错了什么？

任何帮助是极大的赞赏。

答案

在会话中存储更简单的方法：在客户端实体中实现 Serializable然后编写序列化和反序列化函数示例：

class Client implements Serializable{
public function serialize()
{
    return serialize([
        $this->id,
        $this->name,
        $this->color
    ]);
}

public function unserialize($serialized)
{
    list (
        $this->id,
        $this->name,
        $this->color
        ) = unserialize($serialized);
}}

在此之后你几乎可以在任何地方使用它

$this->session->set('client',$client);
$this->session->get('client');

添加要序列化和反序列化函数的任何其他必填字段
