How to send the authentication cookie WebRequest and receive the response in JIRA through REST api?

Question

all

I am working on JIRA, i am sending the authentication request from saparate code and i am getting the response, later i need to fetch all issues from the JIRA than i am sending the request that time i am getting the 401 (Unauthorized) while i am sending the same username and password with gZip compression. my first request code is following where from i am getting the proper response as authenticated.

string urll = ConfigurationManager.AppSettings["globalUrlForLP"];
HttpWebRequest request;
WebResponse response;
String uri;
LpResponse lp_response;
uri = urll + url;
request = WebRequest.Create(uri) as HttpWebRequest;
request.Credentials = CredentialCache.DefaultCredentials;
request.Method = verb;
request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
request.Headers.Set("Authorization", Convert.ToBase64String(Encoding.ASCII.GetBytes(this.Username + ":" + this._password)));

if (null != data)
{
    request.ContentType = "application/json";
    String jsonPayload = JsonConvert.SerializeObject(data);
    byte[] jsonPayloadByteArray = Encoding.ASCII.GetBytes(jsonPayload.ToCharArray());
    request.GetRequestStream().Write(jsonPayloadByteArray, 0, jsonPayloadByteArray.Length);
}
lp_response = new LpResponse();
try
{
     response = request.GetResponse();
     StreamReader reader = new StreamReader(response.GetResponseStream());
     lp_response.response = reader.ReadToEnd();
}
catch (Exception e)
{
     lp_response.error = e;
}
return lp_response;
}

from it i am getting response as following.

{
  "session": {
  "name": "JSESSIONID",
  "value": "12345678901234567890"
  },
    "loginInfo": {
    "failedLoginCount": 10,
    "loginCount": 127,
    "lastFailedLoginTime": "2014-10-28T06:52:52.211+0000",
    "previousLoginTime": "2014-10-28T06:52:52.211+0000"
     }
}

Now come to the point, I want to get all projects from the JIRA for that i written following code and i am getting here 401 Unathorized. After getting this i read the JIRA REST Api documentation and there i found following.

"Returns information about the caller's session if the caller is authenticated. Note that the response contains the Set-Cookie HTTP headers that must be honoured by the caller. If you are using a cookie-aware HTTP client then it will handle all Set-Cookie headers automatically. This is important because setting the JSESSIONID cookie alone may not be sufficient for the authentication to work."

so please suggest me what i need to do more with following code ?

my Failure code is following.

string url = ConfigurationManager.AppSettings["urlAllJiraProject"];
LpResponse res = new LpResponse();
HttpWebRequest request;
WebResponse response;
List<AllJiraProject> jiraproject = new List<AllJiraProject>();
request = WebRequest.Create(url) as HttpWebRequest;
request.Credentials = CredentialCache.DefaultCredentials;
request.Method = "GET";
request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
request.Headers.Set("Authorization", Convert.ToBase64String(Encoding.ASCII.GetBytes(userNamejira + ":" + passwordjira)));
LpResponse lp_response = new LpResponse();
try
{
    response = request.GetResponse();
    StreamReader reader = new StreamReader(response.GetResponseStream());
    lp_response.response = reader.ReadToEnd();
    jiraproject = (List<AllJiraProject>)JsonConvert.DeserializeObject<List<AllJiraProject>>(lp_response.response.ToString());
}
catch (Exception e)
{
    lp_response.error = e;
}
return jiraproject;

Answer 1

I got it, my code does not have Basic authentication into the header, while API demands the Basic authentication, so i replaced my one line with following two lines.

Replaced line

request.Headers.Set("Authorization", Convert.ToBase64String(Encoding.ASCII.GetBytes(userNamejira + ":" + passwordjira)));

Replaced By

byte[] authBytes = Encoding.UTF8.GetBytes("user:password".ToCharArray()); 
request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(authBytes);

Jira has three type of authentications, this one from Basic authentication, it is easy to implement, but i had no idea how to implement authentication from cookie.
