微应用就是网站，钉钉自带的E应用难用，而且前端UI都不是很好，所以倾向使用网站来开发

 

string UrlUserID = "https://oapi.dingtalk.com/message/send?access_token=" + token;　　　　//获取自己的Token        string PostData = "{ \"touser\":\"\",  ";　　　　　　//职员代码，不知道是什么 去通讯录上查，多个请用“|”区分        PostData += "     \"toparty\":\"\", ";　　　　　　　　//部门代码，职员代码和部门代码不能全部为空        PostData += "          \"agentid\":\"\",   ";　　　　//应用代码        PostData += "         \"msgtype\":\"text\",  ";　　　　//消息类型        PostData += "         \"text\":{  ";        PostData += "             \"content\":\"37889\"  ";　　　　//消息内容        PostData += "       }}"; Response.Write(PostDataGetHtml(UrlUserID, PostData));

public string PostDataGetHtml(string uri, string postData)    {        try        {            byte[] data = Encoding.UTF8.GetBytes(postData);            Uri uRI = new Uri(uri);            HttpWebRequest req = WebRequest.Create(uRI) as HttpWebRequest;            req.Method = "POST";            req.KeepAlive = true;            req.ContentType = "application/json";            req.ContentLength = data.Length;            req.AllowAutoRedirect = true;            Stream outStream = req.GetRequestStream();            outStream.Write(data, 0, data.Length);            outStream.Close();            HttpWebResponse res = req.GetResponse() as HttpWebResponse;            Stream inStream = res.GetResponseStream();            StreamReader sr = new StreamReader(inStream, Encoding.UTF8);            string htmlResult = sr.ReadToEnd();            return htmlResult;        }        catch (Exception ex)        {            return "网络错误：" + ex.Message.ToString();        }    }
