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
{
string msg = textBox1.Text;
String textMsg = "{ "msgtype": "text", "text": {"content": "" + msg + ""}}";
string s = Post(WEB_HOOK, textMsg, null);
MessageBox.Show(s);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
#region Post
/// <summary>
/// 以Post方式提交命令
/// </summary>
/// <param name="apiurl">请求的URL</param>
/// <param name="jsonString">请求的json参数</param>
/// <param name="headers">请求头的key-value字典</param>
public static String Post(string apiurl, string jsonString, Dictionary<String, String> headers = null)
{
WebRequest request = WebRequest.Create(@apiurl);
request.Method = "POST";
request.ContentType = "application/json";
if (headers != null)
{
foreach (var keyValue in headers)
{
if (keyValue.Key == "Content-Type")
{
request.ContentType = keyValue.Value;
continue;
}
request.Headers.Add(keyValue.Key, keyValue.Value);
}
}
if (String.IsNullOrEmpty(jsonString))
{
request.ContentLength = 0;
}
else
{
byte[] bs = Encoding.UTF8.GetBytes(jsonString);
request.ContentLength = bs.Length;
Stream newStream = request.GetRequestStream();
newStream.Write(bs, 0, bs.Length);
newStream.Close();
}
WebResponse response = request.GetResponse();
Stream stream = response.GetResponseStream();
Encoding encode = Encoding.UTF8;
StreamReader reader = new StreamReader(stream, encode);
string resultJson = reader.ReadToEnd();
return resultJson;
}
#endregion通知结果如下图
其他消息的类型的可以参照官方文档生成数据即可。
