IdentityServer4 - 错误：未知客户端或未启用：oauthClient

Question

我已经尝试setup a project with IdentityServer4 有一段时间了。但是我收到以下错误：

Sso.Application.CentralHandler: Information: AuthenticationScheme: central was challenged.
IdentityServer4.Hosting.IdentityServerMiddleware: Information: Invoking IdentityServer endpoint: IdentityServer4.Endpoints.AuthorizeEndpoint for /connect/authorize
IdentityServer4.Validation.AuthorizeRequestValidator: Error: Unknown client or not enabled: oauthClient

  }
}

我整天都在寻找如何解决这个错误，但我无法弄清楚它有什么问题。

这是the IdentityProvider project的Startup中的代码：

services
    .AddDbContext<SsoCentralContext>();
//.AddScoped<Repositories.IAccountRepository, Repositories.AccountRepository>();

services.AddIdentity<IdentityUser, IdentityRole>()
    .AddEntityFrameworkStores<SsoCentralContext>();

var isb = services.AddIdentityServer();
isb
    .AddInMemoryClients(new List<Client>
    {
        new Client
        {
            ClientId = "oauthClient",
            ClientName = "oauthClient",
            AllowedGrantTypes = GrantTypes.CodeAndClientCredentials,
            Enabled = true,
            ClientSecrets = new List<Secret> {new Secret("SuperSecretPassword".Sha256())}, // change me!
            AllowedScopes = new List<string> {"weatherforecasts.read"},
            RedirectUris = new List<string>
            {
                "https://localhost:44375/signin-central"
            },
        }
    })
    .AddInMemoryIdentityResources(new List<IdentityResource>
    {
        new IdentityResources.OpenId(),
        new IdentityResources.Profile(),
        new IdentityResources.Email(),
        new IdentityResource
        {
            Name = "role",
            UserClaims = new List<string> {"role"}
        }
    })
    .AddInMemoryApiResources(new List<ApiResource>
    {
        new ApiResource
        {
            Name = "api1",
            DisplayName = "API #1",
            Description = "Allow the application to access API #1 on your behalf",
            Scopes = new List<string> { "weatherforecasts.read", "weatherforecasts.write"},
            ApiSecrets = new List<Secret> {new Secret("ScopeSecret".Sha256())},
            UserClaims = new List<string> {"role"}
        }
    })
    .AddInMemoryApiScopes(new List<ApiScope>
    {
        new ApiScope("weatherforecasts.read", "Read Access to API #1"),
        new ApiScope("weatherforecasts.write", "Write Access to API #1")
    })
    .AddTestUsers(new List<IdentityServer4.Test.TestUser>
    {
        new IdentityServer4.Test.TestUser
        {
            SubjectId = "5BE86359-073C-434B-AD2D-A3932222DABE",
            Username = "Pieterjan",
            Password = "password",
            Claims = new List<System.Security.Claims.Claim> {
                new System.Security.Claims.Claim(IdentityModel.JwtClaimTypes.Email, "pieterjan@example.com"),
                new System.Security.Claims.Claim(IdentityModel.JwtClaimTypes.Role, "admin")
            }
        }
    })
    .AddDeveloperSigningCredential();

isb
    .AddOperationalStore(options =>
    {
        options.ConfigureDbContext = (builder) => builder.UseInMemoryDatabase("SsoCentral");
    })
    .AddConfigurationStore(options =>
    {
        options.ConfigureDbContext = (builder) => builder.UseInMemoryDatabase("SsoCentral");
    });
isb.AddAspNetIdentity<IdentityUser>();

上面的代码肯定会被调用，所以oauthClient 肯定存在。客户端也肯定是启用的。

Identity 项目的Startup 中的This is the code：

services
    .AddAuthentication(options =>
    {
    })
    .AddOAuth<CentralOptions, CentralHandler>("central", options =>
    {
        options.ClaimsIssuer = "https://localhost:44359"; // This is the URL of the IdentityProvider
        options.SaveTokens = true;
        options.ClientId = "oauthClient";
        options.ClientSecret = "SuperSecretPassword";
        options.Scope.Add("weatherforecasts.read");
        options.UsePkce = true;
    });

如何解决此错误？有人知道如何找出这里出了什么问题吗？

我还需要在此处配置的内容之上使用OpenIdConnect 吗？

更新：

我添加了一个调用，只是为了从 IS4 ClientStore 获取客户端：

[HttpGet("Clients")]
public async Task<IActionResult> GetClients()
{
    //var client = await clientStore.FindClientByIdAsync("SsoApplicationClient");
    var _inner = (IdentityServer4.EntityFramework.Stores.ClientStore)clientStore.GetType().GetField("_inner", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance).GetValue(clientStore);
    var Context = (IdentityServer4.EntityFramework.DbContexts.ConfigurationDbContext)_inner.GetType().GetField("Context", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance).GetValue(_inner);
    var Clients = Context.Clients;

    return Ok(Clients);
}

令我惊讶的是，我从中得到的是一个完全空的列表：

好的，所以当你有以下配置时：

services.AddIdentityServer()
    ...
    .AddOperationalStore(options =>
    {
        options.ConfigureDbContext = (builder) => builder.UseInMemoryDatabase("SsoCentral");
    })
    .AddConfigurationStore(options =>
    {
        options.ConfigureDbContext = (builder) => builder.UseInMemoryDatabase("SsoCentral");
    })

InMemoryClients 不再存在。刚刚将其注释掉，现在似乎可以正常工作了。
