OpenIdConnect 中间件不断向请求添加“配置文件”范围

Question

我想弄清楚 OAuth2.0、OIDC1.0 和 IdentityServer4。我已经设置了一个测试 MVC Core 客户端，只请求了“openid”范围。但不知何故，OpenIdConnnect 中间件不断将“profile”范围添加到请求的范围中。 “profile”是强制范围吗？我应该启用它吗？或者我在这里做错了什么？如有任何意见，我将不胜感激。

IdSrv 资源：

_identityResources = new List<IdentityResource>
            {
                new IdentityResources.OpenId(),
                new IdentityResource
                {
                    Name = "test_user",
                    UserClaims = new[] { "test_user.email" }
                }
            };

            _apiResources = new List<ApiResource>
            {
                new ApiResource
                {
                    Name = "test_api",
                    Scopes =
                    {
                        new Scope()
                        {
                            Name = "test_api.account.create",
                            UserClaims = new[] { "test_api.account.create" }
                        }
                    }
                }
            };

IdSrv 客户端配置：

new Client
                {
                    ClientId = "client.mvcx",
                    ClientName = "MVC Core Client",
                    AllowedGrantTypes = GrantTypes.Hybrid,
                    AllowAccessTokensViaBrowser = false,

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

                    RedirectUris = { Common.Addresses.Client + "/signin-oidc" },
                    PostLogoutRedirectUris = { Common.Addresses.Client },
                    LogoutUri = Common.Addresses.Client + "/signout-oidc",

                    AllowedScopes =
                    {
                        IdentityServerConstants.StandardScopes.OpenId
                    },
                    AllowOfflineAccess = false,
                    RequireConsent = false,

                    AlwaysIncludeUserClaimsInIdToken = true

                },

MVC 客户端：

app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationScheme = "cookies",
                AutomaticAuthenticate = true,
                ExpireTimeSpan = TimeSpan.FromMinutes(60)
            });

            JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();

            app.UseOpenIdConnectAuthentication(new OpenIdConnectOptions
            {
                AuthenticationScheme = "oidc",
                SignInScheme = "cookies",

                Authority = Common.Addresses.IdSrv,
                RequireHttpsMetadata = false,

                ClientId = "client.mvcx",
                ClientSecret = "secret",

                ResponseType = "code id_token",
                Scope = { "openid" },

                SaveTokens = true,

                TokenValidationParameters = new Microsoft.IdentityModel.Tokens.TokenValidationParameters
                {
                    NameClaimType = IdentityModel.JwtClaimTypes.Name,
                    RoleClaimType = IdentityModel.JwtClaimTypes.Role,
                },

Answer 1

OpenIdConnectionOptions 自动请求 openid 和 profile 范围（请参阅 source code），并在 Scope 属性上使用私有设置器。

当您设置范围时，您不是在设置新列表，而是添加到现有列表中。

清除然后添加范围有效：

var options = new OpenIdConnectOptions();
options.Scope.Clear();
options.Scope.Add("openid");
app.UseOpenIdConnectAuthentication(options);
