原文:钉钉微应用发送消息

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();
        }
    }
