企业微信官方文档：群机器人配置说明 - 企业微信API
主要问题描述：markdown -content显示和自己postman发送的不一致，后来自己手动拼凑的就可以，发现是每个内容都需要换行\n
代码实例如下：
public static string getContent(List<KitonWarning> data, List<GroupProjectDetail> pro, string title, List<string> SendType){try{string titlemsg = "# <font color=\\\"info\\\">【" + title + "】</font> 信息发布系统报警提醒\n";string clientstate = "";string projectstate = "";if (SendType.Any(a => a == "1"))//离线{List<KitonWarning> list = data.Where(a => a.State != 1).ToList();if (list.Count > 0){clientstate += " > ## 离线清单（<font color=\\\"warning\\\">" + list.Count + "台</font>）\n";foreach (KitonWarning item in list){clientstate += " > " + item.ClientCode + ", 最后登录时间：" + Convert.ToDateTime(item.LastLoginTime).ToString("yyyy-MM-dd HH:mm:dd")+ "\n";}}}if (SendType.Any(a => a == "1")){List<GroupProjectDetail> list = pro.Where(a => a.TodayProject == 0 || a.NextdayProject == 0).ToList();if (list.Count > 0){projectstate = " > ## 节目单异常清单（<font color=\\\"warning\\\">" + list.Count + "个</font>）\n";foreach (GroupProjectDetail item in list){projectstate += " > " + item.GroupName + ", 今日节目单 " + (item.TodayProject == 0 ? "<font color=\\\"warning\\\">无</font>" : "<font color=\\\"comment\\\">有</font>") + " 次日节目单 " + (item.NextdayProject == 0 ? " <font color=\\\"warning\\\">无</font>" : "<font color=\\\"comment\\\">有</font>")+ "\n";}}}if (clientstate == "" && projectstate == ""){return "";}else{return titlemsg + clientstate + projectstate;}}catch (Exception ex){return "";}}
string content = QywxRobot.getContent(data, GroupProjectDetailList, item.GroupName, Monitor.MonitorContent); if (content == "")//无数据{HDLogManager.LogEntity.Info("机器人无需推送【" + item.GroupName + "】--无报警信息");}else{content += " >";foreach (string str in towx){content += "<@" + str + ">";} string param = "{\"msgtype\":\"markdown\",\"markdown\":{\"content\":\"" + content + "\"}}"; string qyresult = HttpData.requestPost(Monitor.RobotUrl, param);//调取企业机器人RobotResult qy = objectConvertHelper.getobjectByJson<RobotResult>(qyresult);if (qy.errcode == 0){HDLogManager.LogEntity.Info("机器人推送【" + item.GroupName + "】成功");}else{HDLogManager.LogEntity.Error("机器人推送【" + item.GroupName + "】失败--" + qy.errmsg);}}
