I have been provided with two services in which ist service is used for login purpose and it will return an xml node token which i to be added as the header in all other services call,
In the attached sample code there are two functions in function CreateObject() i am hitting login service and am successfully able to get the response and from response i fetched the token and call other function with token search(string token) and passed the token in header but its giving an exception [System.Net.WebException] = {"The remote server returned an error: (403) Forbidden."}
But when i see in chrome Advanced Rest Client its giving the expected response
any suggestion or solution in right direction will be highly appreciable
Please See The Code Below
private void CreateObject()
{
try
{
string abc = "";
Stream datastream;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("www.example.com/abc/login");
request.CookieContainer = new CookieContainer();
request.AllowAutoRedirect = true;
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
request.ContentType = "application/x-www-form-urlencoded";
request.Accept = "application/xml";
request.KeepAlive = true;
String postData = "";
request.Method = "POST";
postData = String.Format("username={0}&password={1}", "sample", "sample");
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentLength = byteArray.Length;
datastream = request.GetRequestStream();
datastream.Write(byteArray, 0, byteArray.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
datastream = response.GetResponseStream();
String sourceCode = "";
using (StreamReader reader = new StreamReader(datastream))
{
sourceCode = reader.ReadToEnd();
}
int pos = sourceCode.IndexOf("<?");
string xmlpart = sourceCode.Substring(pos);
//XmlReader reader1 = XmlReader.Create(sourceCode);
XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlpart);
XmlNodeList objNodeList = doc.GetElementsByTagName("token");
string tokens = objNodeList[0].ChildNodes.Item(0).InnerText.Trim();
search(tokens);
}
catch (Exception e)
{
}
}
public void search(string token)
{
Stream datastream;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://example.com/services/suggestions/search");
request.CookieContainer = new CookieContainer();
// request.AllowAutoRedirect = true;
System.Net.ServicePointManager.Expect100Continue = false;
request.Headers.Add("x-csrf-token", token);
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
request.ContentType = "application/x-www-form-urlencoded";
request.Accept = "application/x-cdf,text/html,application/xhtml+xml,application/json,application/xml;q=0.9,*/*;q=0.8";
String postData = "";
request.Method = "POST";
request.KeepAlive = true;
postData = String.Format("param1={0}¶m2={1}¶m3={2}¶m4={3}¶m5={4}¶m6={5}¶m7={6}¶m8={7}", "0", "1","1","1","0","1","2015-06-22","2015-06-22");
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentLength = byteArray.Length;
datastream = request.GetRequestStream();
datastream.Write(byteArray, 0, byteArray.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
datastream = response.GetResponseStream();
String sourceCode = "";
using (StreamReader reader = new StreamReader(datastream))
{
sourceCode = reader.ReadToEnd();
}
}
Finally i figured out what was the issue
i was creating new cookie container for both the request
request.CookieContainer = new CookieContainer();
thus server was unable to authenticate
Error was resolved by using this code
CookieContainer cookieJar = new CookieContainer();
private void CreateObject()
{
try
{
string abc = "";
Stream datastream;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("www.example.com/abc/login");
request.CookieContainer = cookieJar;

doc.LoadXml(xmlpart);
