webapi with basic authorize - asp.net-mvc

Question

I've created a WebApi with .NET.
I want to secure some methods.
I would like only the users in aspnetuser table can execute this methods
I've created as
public class BasicAuthHttpModule : IHttpModule
and in the web.config I configured this as
<system.webServer>
<modules>
<add name="BasicAuthHttpModule" type="WebHostBasicAuth.Modules.BasicAuthHttpModule"/>
</modules>
</system.webServer>
And my BasicAuthHttpModule.cs:
I check the email and password with the aspnetusers tabla
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http.Headers;
using System.Security.Principal;
using System.Text;
using System.Threading;
using System.Web;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.AspNet.Identity.Owin;
using Microsoft.Owin;
using ServicioProx360.Models;
using ServicioProx360;
namespace WebHostBasicAuth.Modules
{
public class BasicAuthHttpModule: IHttpModule
{
private const string Realm = "WebAPI Authentication";
public void Init(HttpApplication context)
{
// Se registran los manejadores de los eventos
context.AuthenticateRequest += OnApplicationAuthenticateRequest;
context.EndRequest += OnApplicationEndRequest;
}
private static void SetPrincipal(IPrincipal principal)
{
Thread.CurrentPrincipal = principal;
if (HttpContext.Current != null)
{
HttpContext.Current.User = principal;
}
}
private static bool AuthenticateUser(string credentials)
{
var encoding = Encoding.GetEncoding("iso-8859-1");
credentials = encoding.GetString(Convert.FromBase64String(credentials));
var credentialsArray = credentials.Split(':');
var username = credentialsArray[0];
var password = credentialsArray[1];
var manager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
ApplicationUser usuario = manager.Find(username, password);
/* Aquí se validan las credenciales o el token enviado en el encabezado de la solicitud */
// if (!(username == "test" && password == "test"))
if (usuario==null)
{
return false;
}
var identity = new GenericIdentity(usuario.UserName);
SetPrincipal(new GenericPrincipal(identity, new string[] { "CIUDADADNO" }));
return true;
}
private static void OnApplicationAuthenticateRequest(object sender, EventArgs e)
{
var request = HttpContext.Current.Request;
var authHeader = request.Headers["Authorization"];
if (authHeader != null)
{
var authHeaderVal = AuthenticationHeaderValue.Parse(authHeader);
// Se valida si el esquema de autenticación es básico (Basic Authentication)
if (authHeaderVal.Scheme.Equals("basic", StringComparison.OrdinalIgnoreCase) && authHeaderVal.Parameter != null)
{
AuthenticateUser(authHeaderVal.Parameter);
}
}
}
// Si la solicitud no fue aprobada, se agrega el encabezado WWW-Authenticate a la respuesta
private static void OnApplicationEndRequest(object sender, EventArgs e)
{
var response = HttpContext.Current.Response;
if (response.StatusCode == 401)
{
response.Headers.Add("WWW-Authenticate", string.Format("Basic realm=\"{0}\"", Realm));
}
}
public void Dispose()
{
}
}
}
but it doen't work fine. if method is [authorize], it ask me for the email and password,I put correct data, but it ask again, again,again.
Can you help me?
Thank you very much
