使用 OpenIddict 刷新令牌始终返回 null

Question

Since the migration from OpenIdDict 2.x to 3.X, we are not able to use refreshtoken anymore. Our code is based on dotnet core 3.1

The processing of user/password works fine and the user receives his tokens (access, id and refresh)

But as soon as we want to send a refresh token, the process of getting the principal from the user returns a null.

var info = await HttpContext.AuthenticateAsync(OpenIddictValidationAspNetCoreDefaults.AuthenticationScheme); var user = await _userManager.GetUserAsync(info.Principal);

The error message

System.ArgumentNullException: Value cannot be null. (Parameter 'principal')

Here is the code we use to bootstrap Openiddict

startup.cs

services.AddOpenIddict()
    .AddCore(options =>
    {
        options.UseEntityFrameworkCore()
            .UseDbContext<DataContext>();
    })
    .AddServer(options =>
    {
        options.SetTokenEndpointUris("/connect/token")
            .AllowPasswordFlow()
            .AllowRefreshTokenFlow();

        options.SetAccessTokenLifetime(TimeSpan.FromDays(1));
        options.SetRefreshTokenLifetime(TimeSpan.FromDays(1));
        options.AcceptAnonymousClients();
        options.AddDevelopmentEncryptionCertificate();
        options.AddDevelopmentSigningCertificate();
        options.RequireProofKeyForCodeExchange();

        options.UseAspNetCore()
            .EnableTokenEndpointPassthrough();
    })
    .AddValidation(options =>
    {
        options.UseLocalServer();
        options.UseAspNetCore();
    });

        default:

            yield break;
    }
}

Most of the code is coming from the samples from OpenIddict.

I really don't understand what's wrong

Try to add setCopes also to CheckRefreshTokenGrantType, I use it and it works for me:

if (request.IsRefreshTokenGrantType())
        {
            // Retrieve the claims principal stored in the refresh token.
            var info = await HttpContext.AuthenticateAsync(OpenIddictServerAspNetCoreDefaults.AuthenticationScheme);

            // Retrieve the user profile corresponding to the refresh token.
            // Note: if you want to automatically invalidate the refresh token
            // when the user password/roles change, use the following line instead:
            // var user = _signInManager.ValidateSecurityStampAsync(info.Principal);
            var user = await _userManager.GetUserAsync(info.Principal);
            if (user == null)
            {
                var properties = new AuthenticationProperties(new Dictionary<string, string>
                {
                    [OpenIddictServerAspNetCoreConstants.Properties.Error] = Errors.InvalidGrant,
                    [OpenIddictServerAspNetCoreConstants.Properties.ErrorDescription] = "The refresh token is no longer valid."
                });

                return Forbid(properties, OpenIddictServerAspNetCoreDefaults.AuthenticationScheme);
            }

            // Ensure the user is still allowed to sign in.
            if (!await _signInManager.CanSignInAsync(user))
            {
                var properties = new AuthenticationProperties(new Dictionary<string, string>
                {
                    [OpenIddictServerAspNetCoreConstants.Properties.Error] = Errors.InvalidGrant,
                    [OpenIddictServerAspNetCoreConstants.Properties.ErrorDescription] = "The user is no longer allowed to sign in."
                });

                return Forbid(properties, OpenIddictServerAspNetCoreDefaults.AuthenticationScheme);
            }

            // Create a new ClaimsPrincipal containing the claims that
            // will be used to create an id_token, a token or a code.
            var principal = await _signInManager.CreateUserPrincipalAsync(user);

            //Add claims to the LocalTokenValidationApi 
            principal.SetResources("LocalTokenValidationApi");

            // Set the list of scopes granted to the client application.
            principal.SetScopes(new[]
            {
                Scopes.OpenId,
                Scopes.Email,
                Scopes.Profile,
                Scopes.Roles,
                Scopes.OfflineAccess
            }.Intersect(request.GetScopes()));

            foreach (var claim in principal.Claims)
            {
                claim.SetDestinations(GetDestinations(claim, principal));
            }

            return SignIn(principal, OpenIddictServerAspNetCoreDefaults.AuthenticationScheme);
        }
