IdentityServer4总是返回“错误”：“invalid_scope”

Question

我正在使用 IdentityServer4(4.0.4)，但是它不返回 access_token，它总是返回："error": "invalid_scope"

只需添加以下代码和 Nuget 包 IdentityServer4(4.0.4) 和 IdentityServer4.EntityFramework(4.0.4) 即可重新创建该错误。在请求中添加“范围”没有任何区别。

这是由 Postman 触发的端点：

这是我的配置类：

using IdentityServer4;
using IdentityServer4.Models;
using System.Collections.Generic;
using System.Linq;

namespace WebApplication1
{
    public class Config
    {
        public static IEnumerable<ApiResource> GetApiResources()
        {
            return new List<ApiResource>
            {
                new ApiResource("ApiName", "ApiDisplayName")
            };
        }

        public static List<IdentityResource> GetIdentityResources()
        {
            return new List<IdentityResource>
            {
                new IdentityResources.OpenId(),
                new IdentityResources.Profile() // <-- usefull
            };
        }

        public static IEnumerable<Client> GetClients()
        {
            return new[]
            {
                // for public api
                new Client
                {
                    ClientId = "secret_client_id",
                    AllowedGrantTypes = GrantTypes.ClientCredentials,
                    ClientSecrets =
                    {
                        new Secret("secret".Sha256())
                    },
                 AllowedScopes =
                {
                    IdentityServerConstants.StandardScopes.OpenId,
                    IdentityServerConstants.StandardScopes.Profile,
                    "ApiName"
                }
            }
        };
    }
}
}

这是我的Startup课：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

namespace WebApplication1
{
    public class Startup
    {
        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddIdentityServer()
             .AddDeveloperSigningCredential()
             .AddOperationalStore(options =>
             {
                 options.EnableTokenCleanup = true;
                 options.TokenCleanupInterval = 30; // interval in seconds
             })
             .AddInMemoryApiResources(Config.GetApiResources())
             .AddInMemoryClients(Config.GetClients())
             .AddInMemoryIdentityResources(Config.GetIdentityResources());
        }

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

            app.UseIdentityServer();
            app.UseRouting();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapGet("/", async context =>
                {
                    await context.Response.WriteAsync("Hello World!");
                });
            });
        }
    }
}

仔细检查您的客户端是否正在查看您的配置中未配置的范围ApiScopes。在下面的示例中，我的客户端注册正在查看“THIS_IS_AN_INVALID_SCOPE”，但实际上我的ApiScopes.

        public static class Scopes
        {
            public static IEnumerable<ApiScope> Get()
            {
                return new[]
                {
                    new ApiScope("ProtectedResource.Scope1", "Access to ProtectedResource.Scope1"),
                    new ApiScope("ProtectedResource.Scope2", "Access to ProtectedResource.Scope2")
                };
            }
        }

        public static class Clients
        {
            public static IEnumerable<Client> Get()
            {
                return new List<Client>
                {
                    new Client
                    {
                        ClientId = "IntegrationTests",
                        ClientName = "Example client application using client credentials",
                        AllowedGrantTypes = GrantTypes.ClientCredentials,
                        ClientSecrets = new List<Secret> {new Secret("not_the_actual_password".Sha256())},
                        AllowedScopes = new List<string> {"THIS_IS_AN_INVALID_SCOPE"},
                        AccessTokenLifetime = 300 //5 Minutes
                    },
                };
            }
        }

您必须在配置中添加 ApiScope。在最新的IdentityServer4中进行了如下更改：

        public static IEnumerable<ApiScope> GetApiScopes()
    {
        return new List<ApiScope>
             {
                 new ApiScope(name: "read",   displayName: "Read your data."),
                 new ApiScope(name: "write",  displayName: "Write your data."),
                 new ApiScope(name: "delete", displayName: "Delete your data."),
                 new ApiScope(name: "identityserverapi", displayName: "manage identityserver api endpoints.")
             };
    }

Answer 3

正如 @DES PRO 所提到的，您需要在配置文件中添加 ApiScope，如下所示。

    public static IEnumerable<ApiScope> GetApiScopes()
        {
            return new List<ApiScope>
             {
                 new ApiScope(name: "ApiOne")
             };
        }

然后将范围添加到 Startup.cs 类中的ConfigureService。这回答了 @raphael 的问题“Scopes 类在哪里使用？”

public void ConfigureServices(IServiceCollection services)
{
            services.AddIdentityServer()
                .AddInMemoryApiResources(Configuration.GetApis())
                .AddInMemoryClients(Configuration.GetClients())
                .AddInMemoryApiScopes(Configuration.GetApiScopes())
                .AddDeveloperSigningCredential();

            services.AddControllersWithViews();
}

Answer 4

您必须始终包含openid范围，因为这是 OpenID-Connect 中必需的范围。

在 IdentityServer 中，StandardScopes 在这里定义 https://github.com/IdentityServer/IdentityServer4/blob/main/src/IdentityServer4/src/IdentityServerConstants.cs

但实际上它只是一个字符串。因此，您可以使用“openid”或 IdentityServerConstants.StandardScopes.OpenId
