token based authentication in WCF service.

Hi Nalesh,

In first link http://www.nullskull.com/a/10475154/token-based-authentication-in-wcf-service.aspx

string UserToken = string.Empty;
//Method to get employee data
public Employee GetEmpData()
{
//Validating user token
if (IsValidateUser())
{
Employee objEmployee = new Employee();
objEmployee.EmpID = 1;
objEmployee.EmpName = "James";
return objEmployee;
}
else
{
throw new FaultException("Invalid User token to access data.");
}
}
//Method to validate user
public string UserLogin(string userName, string password)
{
//Validating user with static values, you can validate from database
if (userName == "user1" && password == "123")
{
//If user is validated then returning current session id as user token
UserToken = OperationContext.Current.SessionId; // It's return null Value
}
else
{
UserToken = "";
}
return UserToken;
}
//Method to validate user with token
public bool IsValidateUser()
{
//Getting the user token from client request
if (OperationContext.Current.IncomingMessageHeaders.FindHeader("TokenHeader", "TokenNameSpace") == -1)
{
return false;
}
string userIdentityToken = Convert.ToString(OperationContext.Current.IncomingMessageHeaders.GetHeader<string>("TokenHeader", "TokenNameSpace"));
//Authenticating user with token, if it is validated then returning employee data
if (userIdentityToken == UserToken)
{
return true;
}
else
{
return false;
}
}

And second article

https://www.codeproject.com/Articles/1084143/Authentication-Token-Service-for-WCF-Services-Part

using System.Security.Authentication;
using WcfSimpleTokenExample.Interfaces;
using WcfSimpleTokenExample.Model;
namespace WcfSimpleTokenExample.Business
{
public class CodeExampleTokenBuilder : ITokenBuilder
{
internal static string StaticToken = "{B709CE08-D2DE-4201-962B-3BBAC74C5952}";
// here I don't want fixed value;
public string Build(Credentials creds)
{
if (new CodeExampleCredentialsValidator().IsValid(creds))
return StaticToken;
throw new AuthenticationException();
}
}
}

Sir If you have any other idea plz share.
