Question

我将会话数据存储在redis中 - 我需要从另一个甚至不用PHP编写的应用程序中获取它，但是当我尝试在我之前从redis获取的存储会话字符串中使用默认的php unserialize方法时 - 我得到了false

示例序列化会话字符串：

_sf2_attributes|a:2:{s:26:"_security.main.target_path";s:21:"http://taxi/dashboard";s:14:"_security_main";s:787:"C:74:"Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken":699:{a:3:{i:0;s:60:"$2y$13$0LWym6x/aYM.TJkGlKreCO7Pc.lw5sovpbOYdJ3LMEqURiXjsKGVq";i:1;s:6:"public";i:2;s:591:"a:4:{i:0;C:22:"TaxiBundle\Entity\User":253:{a:8:{i:0;s:60:"$2y$13$0LWym6x/aYM.TJkGlKreCO7Pc.lw5sovpbOYdJ3LMEqURiXjsKGVq";i:1;s:31:"s28cx1llhk0gk8cskggk404ko0kw808";i:2;s:10:"mrandersen";i:3;s:10:"mrAndersen";i:4;b:1;i:5;i:3;i:6;s:24:"mrandersen2004@yandex.ru";i:7;s:24:"mrandersen2004@yandex.ru";}}i:1;b:1;i:2;a:2:{i:0;O:41:"Symfony\Component\Security\Core\Role\Role":1:{s:47:"\x00Symfony\Component\Security\Core\Role\Role\x00role";s:16:"ROLE_SUPER_ADMIN";}i:1;O:41:"Symfony\Component\Security\Core\Role\Role":1:{s:47:"\x00Symfony\Component\Security\Core\Role\Role\x00role";s:9:"ROLE_USER";}}i:3;a:0:{}}";}}";}_sf2_flashes|a:0:{}_sf2_meta|a:3:{s:1:"u";i:1485465482;s:1:"c";i:1485459877;s:1:"l";s:6:"864000";}

哪里可以找到symfony默认序列化算法？ THX

Symfony没有任何构建会话序列化算法，它使用内置的PHP与常规serialize / unserialize不同。检查php.net上的this评论，您可以在其中找到手动反序列化php会话数据的方法。基本上它取决于session.serialize_handler设置，但您正在寻找的算法是这样的（只是从我提供的第一个链接复制）：

<?php
class Session {
    public static function unserialize($session_data) {
        $method = ini_get("session.serialize_handler");
        switch ($method) {
            case "php":
                return self::unserialize_php($session_data);
                break;
            case "php_binary":
                return self::unserialize_phpbinary($session_data);
                break;
            default:
                throw new Exception("Unsupported session.serialize_handler: " . $method . ". Supported: php, php_binary");
        }
    }

    private static function unserialize_php($session_data) {
        $return_data = array();
        $offset = 0;
        while ($offset < strlen($session_data)) {
            if (!strstr(substr($session_data, $offset), "|")) {
                throw new Exception("invalid data, remaining: " . substr($session_data, $offset));
            }
            $pos = strpos($session_data, "|", $offset);
            $num = $pos - $offset;
            $varname = substr($session_data, $offset, $num);
            $offset += $num + 1;
            $data = unserialize(substr($session_data, $offset));
            $return_data[$varname] = $data;
            $offset += strlen(serialize($data));
        }
        return $return_data;
    }

    private static function unserialize_phpbinary($session_data) {
        $return_data = array();
        $offset = 0;
        while ($offset < strlen($session_data)) {
            $num = ord($session_data[$offset]);
            $offset += 1;
            $varname = substr($session_data, $offset, $num);
            $offset += $num;
            $data = unserialize(substr($session_data, $offset));
            $return_data[$varname] = $data;
            $offset += strlen(serialize($data));
        }
        return $return_data;
    }
}

从另一个应用程序手动加载Symfony会话数据
