如何在标识服务器 4 中获取客户端的其他声明

Question

在我的身份服务器的启动.cs文件中，我配置了如下服务器。我正在使用 asp.net 身份进行用户管理。

services.AddIdentityServer()
                .AddDeveloperSigningCredential()
                .AddInMemoryPersistedGrants()
                .AddInMemoryIdentityResources(Config.GetIdentityResources())
                .AddInMemoryApiResources(Config.GetApiResources())
                .AddInMemoryClients(Config.GetClients())
                .AddAspNetIdentity<ApplicationUser>();
services.AddTransient<IProfileService, ProfileService>();

我IdentiyResources如下。在这里，我想返回额外的声明作为IS_Token，我想将其用于应用程序的一些进一步的业务逻辑。

public static IEnumerable<IdentityResource> GetIdentityResources()
        {
            return new List<IdentityResource>
                {
                    new IdentityResources.OpenId(),
                    new IdentityResources.Profile(),
                    new IdentityResource("IS_token", new []{ "IS_token" } ),
                };
        }

我还在我的IProfileService内已发行声明中添加了此声明，如下所示。

public class ProfileService : IProfileService
    {
        private readonly IUserClaimsPrincipalFactory<ApplicationUser> _claimsFactory;
        private readonly UserManager<ApplicationUser> _userManager;
        public ProfileService(UserManager<ApplicationUser> userManager, IUserClaimsPrincipalFactory<ApplicationUser> claimsFactory)
        {
            _userManager = userManager;
            _claimsFactory = claimsFactory;
        }
        public async Task GetProfileDataAsync(ProfileDataRequestContext context)
        {
            var sub = context.Subject.GetSubjectId();
            var user = await _userManager.FindByIdAsync(sub);
            var principal = await _claimsFactory.CreateAsync(user);
            var claims = principal.Claims.ToList();
            claims = claims.Where(claim => context.RequestedClaimTypes.Contains(claim.Type)).ToList();
            claims.Add(new Claim(JwtClaimTypes.GivenName, user.UserName));
            claims.Add(new Claim(IdentityServerConstants.StandardScopes.Email, user.Email));
            //Get user claims from AspNetUserClaims table
            var userClaims = await _userManager.GetClaimsAsync(user);
            claims.AddRange(userClaims);
            context.IssuedClaims = claims;
        }
        public async Task IsActiveAsync(IsActiveContext context)
        {
            var sub = context.Subject.GetSubjectId();
            var user = await _userManager.FindByIdAsync(sub);
            context.IsActive = user != null;
        }
    }

我的 MVC 客户端配置如下

               new Client
                    {
                        ClientId = "mvc",
                        ClientName = "MVC Client",
                        AllowedGrantTypes = GrantTypes.HybridAndClientCredentials,
                        RequireConsent = false,
                        ClientSecrets =
                        {
                            new Secret("secret".Sha256())
                        },
                        // where to redirect to after login
                        RedirectUris = { "http://localhost:5002/signin-oidc" },
                        // where to redirect to after logout
                        PostLogoutRedirectUris = { "http://localhost:5002/signout-callback-oidc" },
                        AllowedScopes = new List<string>
                        {
                            IdentityServerConstants.StandardScopes.OpenId,
                            IdentityServerConstants.StandardScopes.Profile,
                            "IS_token",
                            "api"
                        },
                        AllowOfflineAccess = true
                    },

在我的 MVC 应用程序中，我在Startup.cs文件中有以下代码

services.AddMvc();
    JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();
    services.AddAuthentication(options =>
    {
        options.DefaultScheme = "Cookies";
        options.DefaultChallengeScheme = "oidc";
    })
    .AddCookie("Cookies")
    .AddOpenIdConnect("oidc", options =>
    {
        options.SignInScheme = "Cookies";
        options.Authority = "http://localhost:5000";
        options.RequireHttpsMetadata = false;
        options.ClientId = "mvc";
        options.ClientSecret = "secret";
        options.ResponseType = "code id_token";
        options.SaveTokens = true;
        options.GetClaimsFromUserInfoEndpoint = true;
        options.Scope.Add("api");
        options.Scope.Add("offline_access");
    });

当我在身份服务器中对用户进行身份验证并返回到我的安全链接时，我收到了以下声明，但IS_token我的用户声明中缺少这些声明。

我的安全页面的cshtml

<dl>
    @foreach (var claim in User.Claims)
    {
        <dt>@claim.Type</dt>
        <dd>@claim.Value</dd>

    }
    <dt>access token</dt>
    <dd>@await ViewContext.HttpContext.GetTokenAsync("access_token")</dd>
    <dt>refresh token</dt>
    <dd>@await ViewContext.HttpContext.GetTokenAsync("refresh_token")</dd>
</dl> 

这是我的安全页面的屏幕截图

我的安全页面的输出

正如您在图像中看到的IS_token丢失了。我怎样才能获得IS_token索赔???

Answer 1

我需要在身份服务器的客户端配置中设置AlwaysIncludeUserClaimsInIdToken = true。所以我应该定义我的客户端如下。

                new Client
                    {
                        ClientId = "mvc",
                        ClientName = "MVC Client",
                        AllowedGrantTypes = GrantTypes.HybridAndClientCredentials,
                        RequireConsent = false,
                        ClientSecrets =
                        {
                            new Secret("secret".Sha256())
                        },
                        // where to redirect to after login
                        RedirectUris = { "http://localhost:5002/signin-oidc" },
                        // where to redirect to after logout
                        PostLogoutRedirectUris = { "http://localhost:5002/signout-callback-oidc" },
                        AllowedScopes = new List<string>
                        {
                            IdentityServerConstants.StandardScopes.OpenId,
                            IdentityServerConstants.StandardScopes.Profile,
                            "IS_token",
                            "poslink"
                        },
                        AlwaysIncludeUserClaimsInIdToken = true,
                        AllowOfflineAccess = true
                    },

在客户端配置的AddOpenIdConnect中，应添加：

options.Scope.Add("IS_token");

否则，此范围的声明将被GetProfileDataAsync的实现过滤掉
