How to login user and return token and id ? about authorization HOT 4 CLOSED

I'm not nearly @sungam3r, but as of now you're returning usuariodb value, which seems to be an instance of System.String,WebAppEF1.Models.Usuario while your intention is seemingly to return the token and IdUser

Assuming that LoginType is defined something like the following

class LoginType : ObjectGraphType<Login>
{
    public LoginType()
    {
        Field(x => x.Token);
        Field(x => x.IdUser);
    } 
}

and Login is defined something like this

class Login
{
    public string Token;
    public string IdUser;
}

then you'd have to combine it all in your resolver like this presumably

public class LoginAuth : ObjectGraphType
    {
        ...

        public LoginAuth(DataContext context, IConfiguration configuration)
        {
             ...             
             resolve: context =>
             {
                                 
                 ....
   
                 var usuariodb = _context.Usuarios.SingleOrDefault(x => x.Email == login.Email && x.Contrasena == login.Contrasena);
    
                 ...
             
                 var tokenUser = CreateToken(usuariodb);
 
                 // the only changed part here
                 return new Login { Token = tokenUser, IdUser = usuariodb.IdUser };
             });

        }

It is not precise, but should be somewhere close.

P.S. and your mutation would look approximately like this, I think
mutation($login: LoginInput!) { login(login: $login) { IdUser login } }

Hi Ivan, my question is how to trying a mutation login (username and password) and in the response query only show the token and id_user. you understand?

Either change IsTypeOf method of "LoginType" to accept this value or return another value from your resolver.

i buy a coffe for you!!

You return object of type System.ValueTuple2[System.String,WebAppEF1.Models.Usuario] from resolver for field "login" but that field has type LoginType which is not compatible with returned object. The error message is quite verbose. This check happens inside protected virtual void ValidateNodeResult(ExecutionContext context, ExecutionNode node):

if (objectType?.IsTypeOf != null && !objectType.IsTypeOf(result))
{
     throw new InvalidOperationException($"\"{result}\" value of type \"{result.GetType()}\" is not allowed for \"{objectType.Name}\". Either change IsTypeOf method of \"{objectType.Name}\" to accept this value or return another value from your resolver.");
}

Please provide definition of LoginType to investigate further.
