版本 4.0.0 文档中的示例中的 Identity Server 范围无效

我正在使用 IdentityServer4，遵循以下文档https://identityserver4.readthedocs.io/en/latest/quickstarts/1_client_credentials.html https://identityserver4.readthedocs.io/en/latest/quickstarts/1_client_credentials.html

但我得到了invalid_scope使用的客户端中出现错误IdentityModel当使用客户端凭据请求令牌时。

可能我错过了某些步骤，但我已经检查了好几次了。

奇怪的是，身份服务器端点显示以下日志：

Invalid scopes requested, {"ClientId": "client", "ClientName": null, "GrantType": "client_credentials", "Scopes": null, "AuthorizationCode": null, "RefreshToken": null, "UserName": null, "AuthenticationContextReferenceClasses": null, "Tenant": null, "IdP": null, "Raw": {"grant_type": "client_credentials", "scope": "api1", "client_id": "client", "client_secret": "***REDACTED***"}, "$type": "TokenRequestValidationLog"}

这并不奇怪Scopes is null以及后来scope有api1 value?

我正在使用内存值。

public static class Config
{
    public static IEnumerable<IdentityResource> Ids =>
        new IdentityResource[]
        { 
            new IdentityResources.OpenId()
        };

    public static IEnumerable<ApiResource> Apis =>
        new List<ApiResource>
        {
            new ApiResource("api1", "My Api")
        };
    
    public static IEnumerable<Client> Clients =>
        new List<Client>
        {
            new Client
            {
                ClientId = "client",
                AllowedGrantTypes = GrantTypes.ClientCredentials,
                ClientSecrets =
                {
                    new Secret("secret".Sha256())
                },
                AllowedScopes = { "api1" }
            }
        };
    
}

and

public void ConfigureServices(IServiceCollection services)
{
    // uncomment, if you want to add an MVC-based UI
    //services.AddControllersWithViews();

    var builder =
        services
            .AddIdentityServer()
            .AddInMemoryApiResources(Config.Apis)
            .AddInMemoryClients(Config.Clients)
            .AddInMemoryIdentityResources(Config.Ids);

    // not recommended for production - you need to store your key material somewhere secure
    builder.AddDeveloperSigningCredential();
}

public void Configure(IApplicationBuilder app)
{
    if (Environment.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    // uncomment if you want to add MVC
    //app.UseStaticFiles();
    //app.UseRouting();

    app.UseIdentityServer();

    // uncomment, if you want to add MVC
    //app.UseAuthorization();
    //app.UseEndpoints(endpoints =>
    //{
    //    endpoints.MapDefaultControllerRoute();
    //});
}

我可以看到众所周知的配置，尽管它没有提到 api1 作为受支持的范围。

这是客户

var client = new HttpClient();
var discovery = 
    await client.GetDiscoveryDocumentAsync("https://localhost:5001");
if (discovery.IsError)
{
    await Console.Out.WriteLineAsync("Discovery error");
    return;
}

// request token
var clientCredentialsTokenRequest =
    new ClientCredentialsTokenRequest
    {
        Address = discovery.TokenEndpoint,
        ClientId = "client",
        ClientSecret = "secret",
        Scope = "api1"
    };

var tokenResponse = 
    await client.RequestClientCredentialsTokenAsync(clientCredentialsTokenRequest);

我是否缺少任何其他东西来进行最基本的示例工作？

更新1：

好的，我已将 Identity Server 降级到 3.1.3，它可以正常工作。 对于 Identity Server 4.0.0 版本，某些内容必须发生变化。会去那里调查。

找到一个issue https://github.com/IdentityServer/IdentityServer4/issues/4441这为我指明了正确的方向。通过将 ApiResources 替换为 ApiScopes 来修复此问题：

public static IEnumerable<ApiScope> Apis =>
    new List<ApiScope>
    {
        new ApiScope("api1", "My Api")
    };

and

var builder =
    services
        .AddIdentityServer()
        .AddInMemoryApiScopes(Config.Apis)
        //.AddInMemoryApiResources(Config.Apis) //OLD?
        .AddInMemoryClients(Config.Clients)
        .AddInMemoryIdentityResources(Config.Ids);

我认为文档尚未更新。

当我尝试访问受保护的 Api 时，仍然遇到未经授权的情况，但那是另一回事了。
