使用CSFramework开发框架+WebApi模型：无法保存前端操作日志

        [HttpPost]
        public int OperateLog_WriteLog(object content)
        {
            return _business.OperateLog_WriteLog(content);
        }

        public int OperateLog_WriteLog(object content)
        {
            object log = content;//默认

            //特殊处理, webapi接收的object是无法识别的具体对象类型。
            //类型：{Name = "JsonElement" FullName = "System.Text.Json.JsonElement"}            
            if (content.GetType().Name == nameof(System.Text.Json.JsonElement))
            {
                try
                {
                    var json = content.ToString();
                    var tmp = Newtonsoft.Json.JsonConvert.DeserializeObject<sys_LogOperation>(json);
                    if (tmp != null && !String.IsNullOrEmpty(tmp.MSG))
                    {
                        log = tmp;
                    }
                }
                catch { }
            }

            //写入数据库
            new dalLogOperation(_Loginer).WriteLog(log);
            return 1;
        }
