登录后，Identity Server 4 未重定向到 Angular 应用程序

Question

I am using oidc-client in angular. following this Tutorial

import { UserManager, UserManagerSettings, User } from 'oidc-client';

My Client:

export function getClientSettings(): UserManagerSettings {
return {
authority: 'https://localhost:44305/',
client_id: 'angular_spa',
redirect_uri: 'http://localhost:4200/auth-callback',
post_logout_redirect_uri: 'http://localhost:4200/',
response_type: 'id_token token',
scope: 'openid profile api1',
filterProtocolClaims: true,
loadUserInfo: true,
automaticSilentRenew: false
};

In Identity Server I'm using Assembly Microsoft.AspNetCore.Identity.UI, Version=2.1.3.0

I'm adding default identity like this:

[assembly: 
HostingStartup(typeof(WebApp.Areas.Identity.IdentityHostingStartup))]
namespace WebApp.Areas.Identity 
{
   public class IdentityHostingStartup: IHostingStartup {
     public void Configure(IWebHostBuilder builder) {
       builder.ConfigureServices((context, services) => {
         services.AddDbContext < WebAppContext > (options =>
             options.UseSqlite(context.Configuration.GetConnectionString("WebAppContextConnection")));

         services.AddDefaultIdentity < WebAppUser > ()
            .AddEntityFrameworkStores < WebAppContext > ();
     });
    }
  }
}

WebAppUser is derived from IdentityUser

Startup.cs:

public class Startup
{

    private ILogger<DefaultCorsPolicyService> _logger;
    private IHostingEnvironment _env;

    public Startup(ILoggerFactory loggerFactory, IHostingEnvironment env)
    {
        _logger = loggerFactory.CreateLogger<DefaultCorsPolicyService>();
        _env = env;
    }
    private static void SetupIdentityServer(IdentityServerOptions identityServerOptions)
    {
        identityServerOptions.UserInteraction.LoginUrl = new PathString("/Identity/Account/Login");
        //  identityServerOptions.Cors.CorsPolicyName = "CorsPolicy";
    }
    public void ConfigureServices(IServiceCollection services)
    {

        services.AddCors(o => o.AddPolicy("CorsPolicy", builder =>
        {
            builder
             .WithOrigins("https://localhost:44305")
            .AllowAnyOrigin()
                   .AllowAnyMethod()
                   .AllowAnyHeader();
        }));

        //  services.AddMvc();
        var cors = new DefaultCorsPolicyService(_logger)
        {
            AllowAll = true
        };

        var cert = new X509Certificate2(Path.Combine(_env.ContentRootPath, "mycert.pfx"), "xxxxx");
        services.AddIdentityServer(SetupIdentityServer)//SetupIdentityServer
                 .AddSigningCredential(cert)
                 .AddInMemoryApiResources(Config.GetApiResources())
                 .AddInMemoryClients(Config.GetClients())
                 // .AddTestUsers(TestUsers.Users)
                 .AddInMemoryIdentityResources(Config.GetIdentityResources());
                 services.AddSingleton<ICorsPolicyService>(cors);

    }
    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        //loggerFactory.AddConsole();
        app.UseDeveloperExceptionPage();

        app.Map("/api", api =>
        {
            api.UseCors(x => x.AllowAnyHeader().AllowAnyMethod().AllowAnyOrigin());
            api.UseAuthentication();

            api.Run(async context =>
            {
                var result = await context.AuthenticateAsync("api");
                if (!result.Succeeded)
                {
                    context.Response.StatusCode = 401;
                    return;
                }

                context.Response.ContentType = "application/json";
                await context.Response.WriteAsync(JsonConvert.SerializeObject("API Response!"));
            });
        });

        app.UseIdentityServer();

        app.UseStaticFiles();
        app.UseMvcWithDefaultRoute();

        //Run these PMC commands after this.
        //Add - Migration CreateIdentitySchema
        //Update - Database

    }
}

In identity server 4 i have enabled https . So the problem is that from my Angular app if i try to use a protected URL I'm navigated to identity serves login page. Looks like it is authenticating properly against the user that is in database. but then it just refreshes the login page and does not redirects to the callback URL .

here are some logs that might help

sorry i tried to format the logs properly but didn't worked.

UPDATE

my server side config looks like this

 public class Config
{
    public static IEnumerable<ApiResource> GetApiResources()
    {
        return new List<ApiResource>
{
    new ApiResource("api1", "My API")
};
    }

    public static IEnumerable<Client> GetClients()
    {
        return new List<Client>
{
    new Client
    {

        ClientSecrets =
        {
            new Secret("superSecretPassword".Sha256())
        },


            ClientId = "angular_spa",
            ClientName = "Angular 4 Client",
            AllowedGrantTypes = GrantTypes.ImplicitAndClientCredentials ,  //implicit
            AllowedScopes = new List<string> { "openid", "profile", "userInfo", "api1" },

            //AllowedScopes = new List<string> { StandardScopes.OpenId, StandardScopes.Profile, StandardScopes.Email },
     RedirectUris = new List<string> {"http://localhost:4200/auth-callback", "http://localhost:4200/silent-refresh.html"},
            PostLogoutRedirectUris = new List<string> { "http://localhost:4200/" },
            AllowedCorsOrigins = new List<string> { "http://localhost:4200" },
            AllowAccessTokensViaBrowser = true,
            Enabled = true,
            AllowOfflineAccess = true
    }
};
    }
    public static List<IdentityResource> GetIdentityResources()
    {
        return new List<IdentityResource>
{
    new IdentityResources.OpenId(),
    new IdentityResources.Profile() // <-- usefull
};
    }
}

my project structure looks like this

it doesn't have any controllers. Should it have ?

UPDATE 2 looks like i figured out whats wrong.

The returnUrl is not resolving properly on the POST method. it is coming as the complete URL . if i force it to a proper return URL it works

           var redirect_uri =  HttpUtility.ParseQueryString(returnUrl).Get("redirect_uri");

I did as above and used variable 'redirect_uri' in Redirect function. it works but it looks like a hack. Should it automatically get the right thing ?

with this i get 'No state in response' error on Angular side and oidc-client have no user after redirect.

UPDATE

Looks like I'm using some different nuget package. HttpContext.SignInAsync has following constructors.

My HttpContext seems to be defined in

Microsoft.AspNetCore.Mvc.RazorPages

looks like i have wrong Nugets or something. i am trying to supply a proper ClaimsPrincipal as well but not working.

Answer 1

I see there's a bit of confusion concerning the difference between the returnUrl and the redirect_uri. Although the end goal is a redirect to the client's redirect_uri, after authentication the client must actually redirect to the authorize endpoint for further processing (hence the reason why the url is different). You shouldn't need to change the returnUrl at all and can leave it the way it was.

The problem you're facing now is you're not calling HttpContext.SignInAsync after a successful authentication. The SignInAsync method is used to administer a cookie with the user's information that tells the endpoint at the returnUrl that the user was successfully authenticated, and it's okay to return a token to the redirect_uri. There are a lot of overloads for the SignInAsync , but the one I find easiest to use is HttpContext.SignInAsync(string subject, params Claim[] claims) . After doing this you should be able to finish the authentication.

Answer 2

Identity server configuration

Set RedirectUris to your angular application hosted url.

Angular application

openIDImplicitFlowConfiguration.redirect_url = this.oidcConfigService.clientConfiguration.redirect_url;
