Hangfire（任务调度）

官网：hangfire.io

简单用法:

1.放入job

BackgroundJob.Enqueue<IIMService>(c => c.SendBatchSmsByIm(readyBatchSmsCommand.SmsTaskId));

　　　　　2.方法的实现

　　　　　/// <summary>
        /// 调用IM接口发送短信
        /// </summary>
        /// <param name="mobile"></param>
        /// <param name="content"></param>
        /// <returns></returns>
        public async Task<string> SendSmsByIM(string mobile, string content)
        {
            var result = await _gateWayRestfulApi.PostAsync<string>($"Api/PublicAggregator/publicServices/ThirdPartyInterface/SendMsgByIM", new { mobile, content });

            return result;
        }

        /// <summary>
        /// 批量调用IM接口发送短信
        /// </summary>
        /// <param name="taskId"></param>
        /// <returns></returns>

        public async Task SendBatchSmsByIm(string taskId)
        {

            var pageIndex = ;
            var pageSize = ;
            while (true)
            {
                var smsTaskDetails = _asyncRepository.Table.Where(m => m.SmsTaskId == taskId).OrderBy(x => x.CreatedDate).Skip(pageIndex * pageSize).Take(pageSize);

                if (!smsTaskDetails.Any())
                {
                    break;
                }
                foreach (var smsTaskDetail in smsTaskDetails)
                {
                    await SendSmsByIM(smsTaskDetail.Mobile, smsTaskDetail.Content);
                }

                pageIndex++;
            }

        }
