c# - Bearer 被 IdentityServer4 中的授权过滤器禁止

Question

测试时IdentityServer4与 AspNetAuthorization 教程我添加了一个简单的 [Authorize(Roles = "Administrator")] 然后我得到了这个错误:

AuthenticationScheme: Bearer was forbidden.

我的用户有这样的声明:新声明(ClaimTypes.Role, "Administrator", ClaimValueTypes.String)。

在ConfigureServices 方法中:

 services.AddAuthorization(options =>
        {
            options.AddPolicy("AdministratorOnly", policy => policy.RequireRole("Administrator"));
        });

        services.AddMvc(config =>
        {
            var policy = new AuthorizationPolicyBuilder()
                        .RequireAuthenticatedUser()
                        .Build();

            config.Filters.Add(new AuthorizeFilter(policy));
        });

在 Configure 方法中:

   app.UseIdentityServerAuthentication(new IdentityServerAuthenticationOptions()
        {
            Authority = "http://localhost:5000",
            ScopeName = "openid",
            AutomaticAuthenticate = true,
            AutomaticChallenge = true,
            RequireHttpsMetadata = false,
        });

调试输出:

Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker: Debug: Executing action LearningEntityServer4.OAuth.ValuesController.Get (LearningEntityServer4.OAuth)
Microsoft.AspNetCore.Authorization.DefaultAuthorizationService: Information: Authorization was successful for user: myuser.
Microsoft.AspNetCore.Authorization.DefaultAuthorizationService: Information: Authorization failed for user: myuser.
Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker: Warning: Authorization failed for the request at filter 'Microsoft.AspNetCore.Mvc.Authorization.AuthorizeFilter'.
Microsoft.AspNetCore.Mvc.ChallengeResult: Information: Executing ChallengeResult with authentication schemes ().
Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerMiddleware: Information: AuthenticationScheme: Bearer was forbidden.

我在配置中遗漏了什么？

PS:我已经查过了this所以发布没有成功。

我终于抽出时间写下声明世界中角色检查如何工作的内部机制:

简而言之 - 确保您用于角色的声明类型与您的 ClaimsIdentity 上的 RoleClaimType 相匹配。或者在您的策略中将 RequireRole 替换为 RequireClaim 并使用正确的类型。
