I am implementing IdentityServer4 an I am making 3 diferents proyects:
- IdentityServer (http://localhost:5000)
- API (http://localhost:5001)
- Javascript client (http://localhost:5003)
All the project are created with ASP.NET Core, but the JS Client use static files.
I need that the JS Client connect with the API only with identity token (not access token) because I only need to have access to the API, I dont need to manage user autentication.
I am reading the quickstarts post https://identityserver4.readthedocs.io/en/dev/quickstarts/1_client_credentials.html
As I read I consider that I need to user the Implicit Grand Type and I dont need OpenID Connect, only OAuth2.
Also I read this post https://identityserver4.readthedocs.io/en/dev/quickstarts/7_javascript_client.html But they use access token and I dont need that, to connect to the API I am using oidc-client-js library https://github.com/IdentityModel/oidc-client-js and I search the way to use with the Implicit Grand Type but the methods that I use redirect me to a http://localhost:5000/connect/authorize page (I think this is when I need to use OpenID Connect)
What is the best way to achieve that? What I have wrong? How can I autenticate with the api and call http://localhost:5001/values
IdentityServer Project
Config.cs

{
return new List<Client>

},
// scopes that client has access to
AllowedScopes = new List<string>
{
"api1"
}
}
};
}
Startup.cs
public void ConfigureServices(IServiceCollection services)
{
// configure identity server with in-memory stores, keys, clients and scopes
services.AddDeveloperIdentityServer()
.AddInMemoryScopes(Config.GetScopes())
.AddInMemoryClients(Config.GetClients());
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)

API project
Startup.cs
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMvc();
services.AddSingleton<ITodoRepository, TodoRepository>();
services.AddCors(options =>
{
// this defines a CORS policy called "default"
options.AddPolicy("default", policy =>
{
policy.WithOrigins("http://localhost:5003")
.AllowAnyHeader()
.AllowAnyMethod();
});
});
services.AddMvcCore()
.AddAuthorization()
.AddJsonFormatters();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
app.UseCors("default");
app.UseIdentityServerAuthentication(new IdentityServerAuthenticationOptions
{
Authority = "http://localhost:5000",
ScopeName = "api1",
RequireHttpsMetadata = false
});
app.UseMvc();
}
ValuesController.cs
[Route("api/[controller]")]
[Authorize]
public class ValuesController : Controller
{
// GET api/values
[HttpGet]
public IEnumerable<string> Get()
{
return new string[] { "value1", "value3" };
