使用 OpenIdDict 时不允许 'offline_access' 范围

Question

使用 Asp.Net Core 5.0 with Identity 和 OpenIdDict 我有以下内容：

  services.AddOpenIddict()
  
    .AddCore(x => {
      x.UseEntityFrameworkCore().UseDbContext<Context>().ReplaceDefaultEntities<Application, Authorization, Scope, Token, Int32>();
    })

    .AddServer(x => {

      x.SetAuthorizationEndpointUris("/connect/authorize")
       .SetLogoutEndpointUris("/connect/logout")
       .SetTokenEndpointUris("/connect/token")
       .SetUserinfoEndpointUris("/connect/userinfo");

      x.RegisterScopes(OpenIddictConstants.Scopes.Profile, OpenIddictConstants.Scopes.Email, OpenIddictConstants.Scopes.OfflineAccess);

      x.AllowAuthorizationCodeFlow();

      x.AddDevelopmentEncryptionCertificate().AddDevelopmentSigningCertificate();

      x.UseAspNetCore()
       .EnableAuthorizationEndpointPassthrough()
       .EnableLogoutEndpointPassthrough()
       .EnableTokenEndpointPassthrough()
       .EnableUserinfoEndpointPassthrough()
       .EnableStatusCodePagesIntegration();

    })

    .AddValidation(x => {
      x.UseLocalServer();
      x.UseAspNetCore();
    });

我有以下客户：

  OpenIddictApplicationDescriptor spa = new OpenIddictApplicationDescriptor {
    ClientId = "spa",
    ClientSecret = "secret",
    ConsentType = OpenIddictConstants.ConsentTypes.Implicit,
    PostLogoutRedirectUris = {
      new Uri("https://localhost:5002/oidc-signout")
    },
    RedirectUris = {
      new Uri("https://localhost:5002/oidc-signin"),
      new Uri("https://localhost:5002/oidc-silent-refresh")
    },
    Permissions = {
      OpenIddictConstants.Permissions.Endpoints.Authorization,
      OpenIddictConstants.Permissions.Endpoints.Logout,
      OpenIddictConstants.Permissions.Endpoints.Token,
      OpenIddictConstants.Permissions.GrantTypes.AuthorizationCode,
      OpenIddictConstants.Permissions.GrantTypes.RefreshToken,
      OpenIddictConstants.Permissions.ResponseTypes.Code,
      OpenIddictConstants.Permissions.Scopes.Email,
      OpenIddictConstants.Permissions.Scopes.Profile,
      OpenIddictConstants.Permissions.Prefixes.Scope + "api"
    },
    Requirements = {
      OpenIddictConstants.Requirements.Features.ProofKeyForCodeExchange
    }
  };

在 Angular Spa 客户端应用程序上，我使用的配置是：

const settings: UserManagerSettings = {
  automaticSilentRenew: true,
  authority: "https://localhost:5000",
  client_id: 'spa',
  client_secret: 'secret',
  filterProtocolClaims: true,
  loadUserInfo: true,
  post_logout_redirect_uri: "https://localhost:5002/oidc-signout",
  redirect_uri: "https://localhost:5002/oidc-signin",
  response_mode: 'query',
  response_type: 'code',
  scope: 'openid profile email offline_access api',
  silent_redirect_uri: 'https://localhost:5002/oidc-silent-refresh'
};

当我点击 SPA 登录时，我被重定向并收到错误：

The 'offline_access' scope is not allowed.

如果我在没有 'offline_access' 的情况下使用它，那么一切正常，例如：

scope: 'openid profile email api'

我错过了什么？

Answer 1

在可以使用 offline_access 范围之前，应启用刷新令牌流。

在您的 Startup.cs 中，您应该更改此行：
x.AllowAuthorizationCodeFlow();
变成这样的东西：
x.AllowAuthorizationCodeFlow().AllowRefreshTokenFlow();

还有一个 GitHub issue 与您的问题有关。
