IdentityServer4刷新令牌无效授予

Question

我在 IdentityServer4 中请求新的刷新令牌时遇到一些问题。身份验证后的某个时间，我从 API 收到未经授权的响应，好的，但是当我尝试请求新的刷新令牌时，我从服务器收到 invalid_grant。我确保设置了offline_access，但仍然遇到问题。这是我的代码：

服务器 Config.cs 中的我的客户端

new Client
            {
                ClientId = "myclientId",
                ClientName = "MyClient",
                AllowedGrantTypes = GrantTypes.HybridAndClientCredentials,

                RequireConsent = false,

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

                RedirectUris = { "http://localhost:5002/signin-oidc" },
                PostLogoutRedirectUris = { "http://localhost:5002/signout-callback-oidc" },

                AllowOfflineAccess = true,

                UpdateAccessTokenClaimsOnRefresh = true,

                AllowedScopes =
                {
                    IdentityServerConstants.StandardScopes.OpenId,
                    IdentityServerConstants.StandardScopes.Profile,
                    IdentityServerConstants.StandardScopes.OfflineAccess,
                    ...
                }
            }

来自 MVCclient 的我的 Startup.cs

app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationScheme = "Cookies",
            AccessDeniedPath = "/Home/Error403"
        });

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

            Authority = Configuration["Identity.Url"],
            RequireHttpsMetadata = false,

            ClientId = Configuration["ClientId"],
            ClientSecret = Configuration["ClientSecret"],

            ResponseType = "code id_token",

            Scope = { "openid profile offline_access" },

            GetClaimsFromUserInfoEndpoint = true,
            SaveTokens = true,

        });

在这里我得到 invalid_grant

var disco = await DiscoveryClient.GetAsync(Configuration["Identity.Url"]);
        if (disco.IsError) throw new Exception(disco.Error);

        var tokenClient = new TokenClient(disco.TokenEndpoint, Configuration["ClientId"],
            Configuration["ClientSecret"]);
        var rt = await HttpContext.Authentication.GetTokenAsync("refresh_token");
        var tokenResult = await tokenClient.RequestRefreshTokenAsync(rt);

tokenResult被分配invalid_grant。我错过了什么吗？

尝试更改 mvc 客户端配置中的这一行

Scope = { "openid", "profile", "offline_access" }

注意每个范围周围的引号
