问题描述

清空了一下redis数据库导致session无法使用redis驱动

程序代码

    //seesion配置
    ....
    'type' => 'redis', // or redis or redis_cluster

    'handler' => RedisSessionHandler::class,

    'config' => [
        'file' => [
            'save_path' => runtime_path() . '/sessions',
        ],
        'redis' => [
            'host' => '127.0.0.1',
            'port' => 6379,
            'auth' => '',
            'timeout' => 2,
            'database' => 1,
            'prefix' => env('DB_NAME').'_redis_session_',
        ],
        ...
    ],
    ....

追踪了一下代码
namespace Workerman\Protocols\Http;
namespace Workerman\Protocols\Http;

/**
 * Class Session
 * @package Workerman\Protocols\Http
 */
class Session
{
        public function __construct(string $sessionId)
    {
        static::checkSessionId($sessionId);
        if (static::$handler === null) {
            static::initHandler();
        }
        $this->sessionId = $sessionId;
        //这个read返回了false
        if ($data = static::$handler->read($sessionId)) {
            $this->data = unserialize($data);
        }

        下面这个是具体的执行方法
            /**
     * {@inheritdoc}
     * @param string $sessionId
     * @return string
     * @throws RedisException
     * @throws Throwable
     */
    public function read(string $sessionId): string
    {
        try {
            //在这里返回了false  不应该是先写入session在读取吗
            return $this->redis->get($sessionId);
        } catch (Throwable $e) {
            $msg = strtolower($e->getMessage());
            if ($msg === 'connection lost' || strpos($msg, 'went away')) {
                $this->connect();
                return $this->redis->get($sessionId);
            }
            throw $e;
        }
    }
    }
}

v5还没发正式版，你先手动改成 return (string)$this->redis->get($sessionId);

可以了这个改包的话线上也得手动改可否升级下此处代码

短时间内不会发版本，因为有很多提交还没验证，你先手动改吧
