core直接获取报异常数据

        [ResponseCache(Duration = 0, Location = ResponseCacheLocation.None, NoStore = true)]
        public IActionResult Error()
        {
            var _IExceptionHandlerFeature = HttpContext.Features.Get<IExceptionHandlerPathFeature>();
            var _Exception = _IExceptionHandlerFeature?.Error;
            sys_Log errorlog = new sys_Log();
            errorlog.gid = new Guid();
            errorlog.IpAddress = HttpContext.Connection.RemoteIpAddress.ToString();
            errorlog.PageUrl = _IExceptionHandlerFeature.Path;
            errorlog.ShortMessage = _Exception.Message;
            errorlog.FullMessage = _Exception.StackTrace;
            errorlog.userName = _account.UserName;
            errorlog.createTime = DateTime.Now;
            _logService.AddLog(errorlog);
            return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });
        }
