Get logged in user

Question

In my project I have an authentication module and logout. But I wanted when the user logged in I’d get the id of it so that I would show the information concerning the login of it. Like a view details. But that the user who logged in, had a link and in that link had the id so that when he clicked on the details page showed the information and if you want to edit it is also possible to take this id.

Namely, I’m using custom authentication. So how can I do this ?

I’ll put my actions of login and logout:

   public ActionResult Index()
    {
        return View();
    }
    [HttpPost]
    public ActionResult Index(String Login, String Senha)
    {
        //verificando login pelo usuario do banco de dados ...
        Usuario login = db.Usuarios.Where(x => x.Login == Login && x.Senha == Senha).FirstOrDefault();
        if (login != null)
        {
            FormsAuthentication.SetAuthCookie(Login, false);
            Session.Add(".PermissionCookie", login.Perfil);
            return RedirectToAction("Index", "Home"); //pagina padrao para todos os usuarios...
        }
        return RedirectToAction("Index");
    }
    public ActionResult Sair()
    {

        FormsAuthentication.SignOut();
        Session.Remove(".PermissionCookie");
        return RedirectToAction("Index");
    }       

Answer 1

The reply of @Diegozanardo gets very close to the request in question. I will just add some information:

SetAuthCookie

I think it’s wrong to put an ID field on a Cookie who accepts String, then I’d change to this:

FormsAuthentication.SetAuthCookie(login.Login.toString(), false);

Controller, nay View

public ActionResult Detalhes()
{
    if (User.Identity.IsAuthenticated)
    {
        var userName = User.Identity.Name;
        var usuario = db.Usuarios.FirstOrDefault(x => x.Login == userName);

        if (usuario != null)
            return View(usuario);
    }

    return RedirectToAction("Index");
}

View

@model Usuario

<p>Login: @usuario.Login</p>
<p>Data de Nascimento: @usuario.DataNascimento</p>
@* Coloque aqui mais detalhes da sua View *@

Answer 2

First place, the FormsAuthentication.SetAuthCookie receives a String and a Boolean, SetAuthCookie(String, Boolean). Cannot be SetAuthCookie(Usuario, Boolean), how are you doing.

Soon it would look like this, assuming the class Login has been ID:

FormsAuthentication.SetAuthCookie(login.ID.toString(), false);

So your View of details would be:

public ActionResult Detalhes()
{
    if (HttpContext.Current.User.Identity.IsAuthenticated)
    {
        int ID = int.Parse(HttpContext.Current.User.Identity.Name);
        Usuario usuario = db.Usuarios.Where(x => x.ID == ID).FirstOrDefault();
        return View(usuario);
    }
    return RedirectToAction("Index");
}

Yes, using the method .Getuserid()

For the method to be available directly, you need to use:

using Microsoft.AspNet.Identity;

After that you can get the login user id:

User.Identity.GetUserId();
