Export Web Intelligence document to PDF using RESTful SDK – C# .NET code


The sample below was written in C# .NET and demonstrates how to use the Restful SDK to export a webi report to PDF.  It assumes that there are no parameter values that need to be set.

Restful call sequence

The RESTful call sequence is the same as mentioned in document Export Webi Report using the Restful SDK.

C# .NET Source Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
using System.Net;
using System.Xml;
public partial class _Default : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)
        string userName = "Username";
        string password = "Password";
        string auth = "secEnterprise";
        string baseURL = "http://localhost:6405/biprws/";
        string LogonURI = baseURL + "logon/long";
        string InfoStoreURI = baseURL + "raylight/v1/documents/1234"; //1234 is the document id
        string rwsLogonToken;
            //Making GET Request to  /logon/long to receive XML template.
            WebRequest myWebRequest = WebRequest.Create(LogonURI);
            myWebRequest.ContentType = "application/xml";
            myWebRequest.Method = "GET";
            //Returns the response to the request made
            WebResponse myWebResponse = myWebRequest.GetResponse();
            //Creating an instance of StreamReader to read the data stream from the resource
            StreamReader sr = new StreamReader(myWebResponse.GetResponseStream());
            //Reads all the characters from the current position to the end of the stream and store it as string
            string output = sr.ReadToEnd();
            //Initialize a new instance of the XmlDocument class
            XmlDocument doc = new XmlDocument();
            //Loads the document from the specified URI
            //Returns an XmlNodeList containing a list of all descendant elements
            //that match the specified name i.e. attr
            XmlNodeList nodelist = doc.GetElementsByTagName("attr");
            //  Add the logon parameters to the attribute nodes of the document
            foreach (XmlNode node in nodelist)
                if (node.Attributes["name"].Value == "userName")
                    node.InnerText = userName;
                if (node.Attributes["name"].Value == "password")
                    node.InnerText = password;
                if (node.Attributes["name"].Value == "auth")
                    node.InnerText = auth;
            //Making POST request to /logon/long to receive a logon token
            WebRequest myWebRequest1 = WebRequest.Create(LogonURI);
            myWebRequest1.ContentType = "application/xml";
            myWebRequest1.Method = "POST";
            byte[] reqBodyBytes = System.Text.Encoding.Default.GetBytes(doc.OuterXml);
            Stream reqStream = myWebRequest1.GetRequestStream();
            reqStream.Write(reqBodyBytes, 0, reqBodyBytes.Length);
                WebResponse myWebResponse1 = myWebRequest1.GetResponse();
                //Finding the value of the X-SAP-LogonToken
                rwsLogonToken = myWebResponse1.Headers["X-SAP-LogonToken"].ToString();
                //Making GET request to /infostore to retrieve the contents of top level of BI Platform repository.
                HttpWebRequest myWebRequest2 = (HttpWebRequest)WebRequest.Create(InfoStoreURI);
                myWebRequest2.Accept = "application/pdf";
                myWebRequest2.Headers.Add("X-SAP-LogonToken", rwsLogonToken);
                myWebRequest2.Method = "GET";
                WebResponse myWebResponse2 = myWebRequest2.GetResponse();
                FileStream stream = new FileStream(Request.PhysicalApplicationPath + "output.pdf", FileMode.Create);
            catch (WebException ex)
                //error while accessing the network through a pluggable protocol
                Response.Write("<b>" + ex.Message + "</b>");
            catch (Exception ex)
                //generic error
                Response.Write("<b>" + ex.Message + "</b>");
        catch (WebException ex)
            //error while accessing the network through a pluggable protocol
            Response.Write("<b>" + ex.Message + "</b>");
        catch (Exception ex)
            //generic error
            Response.Write("<b>" + ex.Message + "</b>");
