钉钉开发系列机器人发送数据

钉钉的每个群都可以建若干个机器人，有默认的比如github，也可以自定义。我们使用自定义，建立自己的机器人，然后得到一串的URL，只要向这个URL进行POST请求后，就能将消息通知到对应的群中。机器人的创建可以参照官方的文档。

发送通知的代码如下

 

private string WEB_HOOK = "https://oapi.dingtalk.com/robot/send?access_token=XXXXX";  
  
       private void buttonTest_Click(object sender, EventArgs e)  
       {  
           try  
           {  
               //text类型
               //string phone1 = "15009280795";
               //string phone2 = "13609197096";
               //string textMsg = "{ \"msgtype\": \"text\", \"text\": {\"content\": \"" + msg + "\"},\"at\": {\"atMobiles\": [\"" + phone1 + "\",\"" + phone2 + "\"]},\"isAtAll\": false}";
               //link类型
                //string text = "坐飞机也能玩手机？昨日21时15分，海航HU7781次航班的乘客尝了“头啖汤”。";
                //string title = "坐飞机玩手机? 海航东航满足你！";
                //string picUrl = "";
                //string messageUrl = "https://mbd.baidu.com/newspage/data/landingsuper?context=%7B%22nid%22%3A%22news_6433821039443213195%22%7D&n_type=0&p_from=1";
                //string textMsg = "{ \"msgtype\": \"link\", \"link\": {\"text\": \"" + text + "\",\"title\":\"" + title + "\",\"picUrl\":\"" + picUrl + "\",\"messageUrl\":\"" + messageUrl + "\"}}";


               string msg = textBox1.Text;  
               String textMsg = "{ \"msgtype\": \"text\", \"text\": {\"content\": \"" + msg + "\"}}";  
               string s = Post(WEB_HOOK, textMsg, null);
