於C#中開發透過HttpWebRequest發送API URL
http://192.168.0.18:7001/ec2/bookmarks/add?guid=b648c1cf-0d5f-4f7f-8151-b36c1a7ae9a9&cameraId=8a42747b-24c0-bcf5-e0cb-7ed6c083358e&name=人員：paul-Paul&description=單號&startTimeMs=1652432804000&durationMs=60000&tag=單號:OR220413000001

或是用創建事件

http://192.168.0.18:7001/api/createEvent?timestamp=1653039891000&caption=單號OR220413000001-人員：paul-Paul-配編:-產品:-加總數量:

都會收到(401) 未經授權的錯誤

是否有遺漏的部分，再請協助幫忙

謝謝。

string targetUrl = "http://192.168.0.18:7001/ec2/bookmarks/add?guid=" + myuuidAsString
                        + "&cameraId=" + dtcam.Rows[0]["CameraId"].ToString().Trim()
                        + "&name=人員：" + sysinfo.usrid + "-" + dtUsr.Rows[0]["susnm"].ToString().Trim()
                        + "&description=單號"
                        + "&startTimeMs=" + epoch
                        + "&durationMs=60000&tag=單號:" + sShtno + "-配編:" + sDelno + "-產品:" + sPrtno + "-加總數量:" + sQty
                        ;
OR
targetUrl = "http://192.168.0.18:7001/api/createEvent?timestamp=" + epoch                        
                        + "&caption=單號" + sShtno + "-人員：" + sysinfo.usrid + "-" + dtUsr.Rows[0]["susnm"].ToString().Trim()

                        //+ "&metadata={"+"cameraRefs"+":[" + dtcam.Rows[0]["CameraId"].ToString().Trim()+"]}"
                        ;

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(targetUrl);
                req.KeepAlive = true; //是否保持連線
req.Method = "GET";
ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
                ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(ValidateServerCertificate);
                using (WebResponse wr = req.GetResponse())
                {
                    StreamReader sr = new StreamReader(wr.GetResponseStream());
                    result = sr.ReadToEnd();
                    sr.Close();
                }
