钉钉官方定义：https://open.dingtalk.com/document/orgapp/message-notification-overview
开发前需在钉钉开发者后台配置【第三方企业应用】
如何配置请参考：【夏风中的Young Uncle】 https://www.cnblogs.com/woshuaile/p/17514015.html
配置完成后会在钉钉工作台，会展现刚刚配置完成的第三方企业应用
同时也会得到AgentID、AppKey、AppSecret；
放一张实际发送的效果图
图片中1：包含通知标题、通知内容、通知人、通知时间；2：通知状态（状态也可调用钉钉接口进行更改）；3：查看详情，可以在app或PC端打开链接，进入详情页面
主：如果和你想要的效果一致，请继续浏览。否则请搜索查看其他博文（省的浪费时间）。
1、首先把配置放到 webconfig 中
2、实现方法前，需要下载钉钉SDK，获取sdk方法在
直接打开钉钉地址进行sdk下载：https://open.dingtalk.com/document/resourcedownload/download-server-sdk?spm=ding_open_doc.document.0.0.cefe40e9Q56N9D#title-dyi-gqb-z18
下载完成后，会得到 TopSdk.dll 直接放到项目bin文件下。
3、创建ToDoSendOA.cs 类实现第三方应用消息发送方法
//引用
using DingTalk.Api; using DingTalk.Api.Request; using DingTalk.Api.Response;
public class ToDoSendOA{ //获取配置信息
private string DingTalkAgentID = ConfigurationManager.AppSettings["DingTalkAgentID"].ToString(); private string DingTalkAppKey = ConfigurationManager.AppSettings["DingTalkAppKey"].ToString(); private string DingTalkAppSecret = ConfigurationManager.AppSettings["DingTalkAppSecret"].ToString();
///
/// 推送单条任务
///
///
///
private bool SendDingTalkMessage(ToDoMessageEntityOA Msg)
{
#region 参数封装
bool result = false; //获取钉钉Userid,这里是根据登录名，获取数据库保存的钉钉Userid,(可根据实际情况进行修改)，具体获取钉钉USERid,下面会进行讲解
string dingTalkuserid = GetDingTalkUserID(Msg.Receiveuserloginname);
if (string.IsNullOrEmpty(dingTalkuserid))
{
_logInfo.Info("钉钉推送获取推送用户为空：" + "Receiveuserloginname:" + Msg.Receiveuserloginname);
return result;
}
string strTitle = Msg.Title;//传入参数 通知标题 //这的MessageUrl,是为了上面图片3，点击详情进入调转到详情页
string messageUrl = HttpUtility.UrlEncode(GetdingTalkUrl(Msg, WEB_H5_URL, DingTalkLoginUrl, "messgae"));
string firstname = Msg.Firstname;//传入参数通知人
List
{
new FormDomain{ Key="发起人:" ,Value= firstname },
new FormDomain{ Key="通知时间:" ,Value=Msg.Senddate.ToString("yyyy-MM-dd HH:mm:ss")},//传入参数：发送时间
};
var oaModel = new OaMsgModel()
{
Agentid = long.Parse(DingTalkAgentID),
MessageUrl = "dingtalk://dingtalkclient/page/link?url=" + messageUrl + "&pc_slide=" + MsgPcSlide,
PcMessageUrl = "dingtalk://dingtalkclient/page/link?url=" + messageUrl + "&pc_slide=" + MsgPcSlide,
Head = new HeadDomain()
{
Text = strTitle
},
Body = new BodyDomain()
{
Title = strTitle,
Content = Msg.Title,
Form = forms
},
Touser = dingTalkuserid,
MessageType = MessageType.Oa,
Recordstatus = Msg.Recordstatus
};
#endregion
if (GetMessagedingtalk(Msg)<=0)
{
//钉钉通知
DingTalkResponse res = SendAsync(oaModel);
if (res.Success)
{
InsertDingTalk(Msg.Entiid, Msg.Datakey, res.Data, Msg.Workflowtitle,
Msg.Senduserid, Msg.Senduserloginname, Msg.Receiveuserid,
Msg.Receiveuserloginname, Msg.Recordstatus, "Message", "", DateTime.Now, "", Msg.Msgguid.ToString());
result = true;
}
return result;
}
return true;
}}
