Create a new class named 'WebExXMLRequest.cs', this class will contain the XML requests for WebEx services
using System.Configuration; namespace WebExDownloadVideo { public class WebExXmlRequest { string schema_soapenv { get; set; } string schema_xsd { get; set; } string schema_xsi { get; set; } string schema_encodingStyle { get; set; } string schema_serv { get; set; } string siteId { get; set; } string siteName { get; set; } string userName { get; set; } string password { get; set; } public WebExXmlRequest() { schema_soapenv = ConfigurationManager.AppSettings["soapenv"]; schema_xsd = ConfigurationManager.AppSettings["xsd"]; schema_xsi = ConfigurationManager.AppSettings["xsi"]; schema_encodingStyle = ConfigurationManager.AppSettings["encodingStyle"]; schema_serv = ConfigurationManager.AppSettings["serv"]; siteId = ConfigurationManager.AppSettings["SiteId"]; siteName = ConfigurationManager.AppSettings["SiteName"]; userName = ConfigurationManager.AppSettings["UserName"]; password = ConfigurationManager.AppSettings["Password"]; } public string ConstructXMLForStorageAccessTicket() { return "<?xml version='1.0' encoding='UTF-8'?>\r\n" + "<soapenv:Envelope xmlns:soapenv='" + schema_soapenv + "' xmlns:xsd='" + schema_xsd + "' xmlns:xsi='" + schema_xsi + "'>\r\n" + "<soapenv:Body>\r\n" + "<ns1:getStorageAccessTicket soapenv:encodingStyle='" + schema_encodingStyle + "' xmlns:ns1='NBRStorageService'>\r\n" + "<siteId xsi:type='xsd:long'>" + siteId + "</siteId>\r\n" + "<username xsi:type='xsd:string'>" + userName + "</username>\r\n" + "<password xsi:type='xsd:string'>" + password + "</password>\r\n" + "</ns1:getStorageAccessTicket>\r\n" + "</soapenv:Body>\r\n" + "</soapenv:Envelope>"; } public string ConstructXMLForGettingRecordId(string meetingKey) { return "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\r\n" + "<serv:message xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:serv=\"http://www.webex.com/schemas/2002/06/service\">\r\n" + "<header>\r\n" + "<securityContext>\r\n" + "<webExID>" + userName + "</webExID>\r\n" + "<password>" + password + "</password>\r\n" + "<siteName>" + siteName + "</siteName>\r\n" + "</securityContext>\r\n" + "</header>\r\n" + "<body>\r\n" + "<bodyContent xsi:type=\"java:com.webex.service.binding.ep.LstRecording\">\r\n" + "<sessionKey>" + meetingKey + "</sessionKey>\r\n" + "<hostWebExID>" + userName + "</hostWebExID>\r\n" + "</bodyContent>\r\n" + "</body>\r\n" + "</serv:message>"; } public string ConstructXMLForDownloadingNBRFile(string recordId, string ticket) { return "<?xml version='1.0' encoding='UTF-8'?>\r\n" + "<soapenv:Envelope xmlns:soapenv='" + schema_soapenv + "' xmlns:xsd='" + schema_xsd + "' xmlns:xsi='" + schema_xsi + "'>\r\n" + "<soapenv:Body>\r\n" + "<ns1:downloadNBRStorageFile soapenv:encodingStyle='" + schema_encodingStyle + "' xmlns:ns1=\"NBRStorageService\">\r\n" + "<siteId xsi:type='xsd:long'>" + siteId + "</siteId>\r\n" + "<recordId xsi:type=\"xsd:long\">" + recordId + "</recordId>\r\n" + "<ticket xsi:type=\"xsd:string\">" + ticket + "</ticket>\r\n" + "</ns1:downloadNBRStorageFile>\r\n" + "</soapenv:Body>\r\n" + "</soapenv:Envelope>"; } } } -
Now, create another class named 'WebExHelper.cs', this class will send the requests to WebEx XML/NBR services
using System; using System.Configuration; using System.IO; using System.Net; using System.Text; using System.Xml; namespace WebExDownloadVideo { public class WebExHelper { public string GetStorageAccessTicket() { var apiUrl = ConfigurationManager.AppSettings["NBRAPIUrl"]; var xml = new WebExXmlRequest().ConstructXMLForStorageAccessTicket(); var webRequest = System.Net.WebRequest.Create(apiUrl); webRequest.Headers.Add("SOAPAction", apiUrl + "/getStorageAccessTicket"); webRequest.Method = System.Net.WebRequestMethods.Http.Post; webRequest.ContentType = "text/xml;charset=utf-8"; var byteArray = Encoding.UTF8.GetBytes(xml.ToString()); webRequest.ContentLength = byteArray.Length; var dataStream = webRequest.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); var response = webRequest.GetResponse(); dataStream = response.GetResponseStream(); var reader = new System.IO.StreamReader(dataStream); string rawResponse = reader.ReadToEnd(); dataStream.Close(); reader.Close(); response.Close(); string result = string.Empty; XmlDocument xmlResponse = new XmlDocument(); xmlResponse.LoadXml(rawResponse); XmlNodeList ticket = xmlResponse.GetElementsByTagName("ns1:getStorageAccessTicketReturn"); if (ticket.Count > 0) { result = ticket[0].InnerText; } return result; } public string GetRecordId(string meetingKey) { var apiUrl = ConfigurationManager.AppSettings["XMLAPIUrl"]; var xml = new WebExXmlRequest().ConstructXMLForGettingRecordId(meetingKey); var webRequest = WebRequest.Create(apiUrl); webRequest.Method = WebRequestMethods.Http.Post; webRequest.ContentType = "application/x-www-form-urlencoded"; var byteArray = Encoding.UTF8.GetBytes(xml.ToString()); webRequest.ContentLength = byteArray.Length; var dataStream = webRequest.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); var response = webRequest.GetResponse(); dataStream = response.GetResponseStream(); var reader = new System.IO.StreamReader(dataStream); string rawResponse = reader.ReadToEnd(); dataStream.Close(); reader.Close(); response.Close(); string result = string.Empty; XmlDocument xmlResponse = new XmlDocument(); xmlResponse.LoadXml(rawResponse); XmlNodeList recordingIds = xmlResponse.GetElementsByTagName("ep:recordingID"); if (recordingIds.Count > 0) { result = recordingIds[0].InnerText; } return result; } public void DownloadNBRStorageFile(string ticket, string recordId, string meetingKey) { string filePath = "d:\\WebEx_Videos\\" + meetingKey + ".arf"; var apiUrl = ConfigurationManager.AppSettings["NBRAPIUrl"]; var xml = new WebExXmlRequest().ConstructXMLForDownloadingNBRFile(recordId, ticket); var webRequest = System.Net.WebRequest.Create(apiUrl); webRequest.Headers.Add("SOAPAction", apiUrl + "/downloadNBRStorageFile"); webRequest.Method = System.Net.WebRequestMethods.Http.Post; webRequest.ContentType = "text/xml;charset=utf-8"; var byteArray = Encoding.UTF8.GetBytes(xml.ToString()); webRequest.ContentLength = byteArray.Length; var dataStream = webRequest.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); var response = webRequest.GetResponse(); dataStream = response.GetResponseStream(); StringBuilder sb = new StringBuilder(); int bytetoread = 10; string str = ""; using (FileStream fs = File.Create(filePath)) { Byte[] buffer = new Byte[1024]; int read = dataStream.Read(buffer, 0, buffer.Length); str = Encoding.UTF8.GetString(buffer); buffer = new Byte[200]; read = dataStream.Read(buffer, 0, buffer.Length); str = Encoding.UTF8.GetString(buffer); while (read > 0) { buffer = new Byte[bytetoread]; read = dataStream.Read(buffer, 0, buffer.Length); str = Encoding.UTF8.GetString(buffer); if (str.Contains("<")) { bytetoread = 1; } if (str.Contains(">")) { break; } } int cnt = 4; while (cnt > 0) { buffer = new Byte[1]; read = dataStream.Read(buffer, 0, buffer.Length); str = Encoding.UTF8.GetString(buffer); cnt--; } buffer = new Byte[1024]; read = dataStream.Read(buffer, 0, buffer.Length); while (read > 0) { fs.Write(buffer, 0, read); buffer = new Byte[1024]; read = dataStream.Read(buffer, 0, buffer.Length); } } dataStream.Close(); } } } -
In your 'Program.cs' file, paste the code below
using System; using System.Collections.Generic; using System.IO; using System.Linq; namespace WebExDownloadVideo { class Program { static void Main(string[] args) { try { int totalDownloads = 1; //To keep the appointment ids where record id does not exist List<string> recordIdNotFound = new List<string>(); WebExHelper obj = new WebExHelper(); var meetingKeys = new List<string>() { "1234567", "8765444" }; //Make a request to your DB to fetch meeting key foreach (var item in meetingKeys) { bool checkIfFileExist = File.Exists("d:\\WebEx_Videos\\" + item + ".arf"); if (checkIfFileExist) { Console.WriteLine("File already exist for meeting key #" + item); totalDownloads++; } else { try { Console.WriteLine("====================================================================="); #region Get-RecordId Console.WriteLine("Fetching RecordId for meeting key #" + item + "..." + Environment.NewLine); var recordId = obj.GetRecordId(item); Console.WriteLine("Record ID: " + recordId + Environment.NewLine); #endregion if (!string.IsNullOrEmpty(recordId)) { #region Get-Access-Ticket Console.WriteLine("Fetching ticket for accessing NBR storage server..." + Environment.NewLine); var ticket = obj.GetStorageAccessTicket(); Console.WriteLine("Ticket : " + ticket + Environment.NewLine); #endregion if (!string.IsNullOrEmpty(ticket)) { #region Download-Recording Console.WriteLine("Downloading file for meeting key # : " + item + "..." + Environment.NewLine); obj.DownloadNBRStorageFile(ticket, recordId, item); Console.WriteLine("File downloaded successfully for meeting key #: " + item + Environment.NewLine); Console.WriteLine("Total files downloaded : " + totalDownloads + Environment.NewLine); totalDownloads++; #endregion } } else { recordIdNotFound.Add(item); } Console.WriteLine("====================================================================="); } catch (Exception ex) { Console.WriteLine("Error downloading the file for appointment id : " + item + Environment.NewLine + ex.Message); } } } if (recordIdNotFound != null && recordIdNotFound.Any()) { Console.WriteLine("RecordId not found for below Appointments : " + Environment.NewLine); foreach (var item in recordIdNotFound) { Console.WriteLine(item); } } Console.Read(); } catch (Exception ex) { Console.WriteLine(ex.Message); Console.ReadLine(); } } } } -
Build and run the application.
