API for Xamarin app - getting nowhere

Get Help
13

Hi again @sandrino-a0,

The Xamarin app seems to be fine. Here is the code it uses to log in and get the token and claims:

using System.Threading.Tasks;
using AnnoLog.Common;
using AnnoLog.Droid.Services;
using Auth0.OidcClient;
using IdentityModel.OidcClient.Browser;
using Xamarin.Forms;
using static AnnoLog.Common.GlobalInfo;

[assembly: Dependency(typeof(AuthenticationService))]
namespace AnnoLog.Droid.Services
{
    public class AuthenticationService : IAuthService
    {
        private Auth0Client _auth0Client;

        public AuthenticationService()
        {
            _auth0Client = new Auth0Client(new Auth0ClientOptions
            {
                Domain = AuthConfig.Domain,
                ClientId = AuthConfig.ClientId
            });
        }
        public AuthenticationResult AuthenticationResult { get; private set; }

        public async Task<AuthenticationResult> Authenticate()
        {
            var auth0LoginResult = await _auth0Client.LoginAsync(new { audience = AuthConfig.Audience });
            AuthenticationResult authenticationResult;

            if (!auth0LoginResult.IsError)
            {
                authenticationResult = new AuthenticationResult()
                {
                    AccessToken = auth0LoginResult.AccessToken,
                    IdToken = auth0LoginResult.IdentityToken,
                    UserClaims = auth0LoginResult.User.Claims
                };
            }
            else
            {
                authenticationResult = new AuthenticationResult(auth0LoginResult.IsError, auth0LoginResult.Error);
            }
            AuthenticationResult = authenticationResult;
            return authenticationResult;
        }

I changed my startup.cs file according to your example.

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

namespace WebApplication1
{
    public class Startup
    {
        public IConfiguration _configuration;
        
        public Startup(IConfiguration configuration)
        {
            _configuration = configuration;
        }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers();

            // Configure JWT authentication.
            services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
              .AddJwtBearerConfiguration(
                _configuration["Jwt:Issuer"],
                _configuration["Jwt:Audience"]
              );
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app.UseRouting();
            app.UseAuthentication();
            app.UseAuthorization();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });

            app.UseStaticFiles();
        }
    }
}

If I configure an API with the audience as localhost:port is it likely to work? I will try it anyway. One problem I am having is being able to debug the API.

Regards,

Rob
