解决ecshop后台自动退出的办法

function gen_session_key($session_id)
    {
        static $ip = '';
        if ($ip == '')
        {
            $ip = substr($this->_ip, 0, strrpos($this->_ip, '.'));
        }
        return sprintf('%08x', crc32(!empty($_SERVER['HTTP_USER_AGENT']) ? $_SERVER['HTTP_USER_AGENT'] . ROOT_PATH . $ip . $session_id : ROOT_PATH . $ip . $session_id));
  }

function gen_session_key($session_id)
    {
        static $ip = '';
        if ($ip == '')
        {
            $ip = substr($this->_ip, 0, strrpos($this->_ip, '.'));
        }
        return sprintf('%08x', crc32(ROOT_PATH . $ip . $session_id));
    }

替换成

function gen_session_key($session_id) {
        static $ip = '';

//        if ($ip == '')
//        {
//            $ip = substr($this->_ip, 0, strrpos($this->_ip, '.'));
//        }

        return sprintf('%08x', crc32(ROOT_PATH . $ip . $session_id));
}
