authentication - AspNetCore.Authentication.JwtBearer 失败，没有 SecurityTokenValidator 可用于带有 .net core RC2 的 token

Question

我试图让一个简单的端点工作，使用 AspNew.Security.OpenIdConnect.Server 发布和使用 JWT token 来发布 token 并使用 Microsoft.AspNetCore.Authentication.JwtBearer 进行验证。

我可以很好地生成 token ，但尝试验证 token 失败并出现错误 Bearer was not authenticated. Failure message: No SecurityTokenValidator available for token: {token}
在这一点上，我已经剥离了所有内容并具有以下内容:

            app.UseJwtBearerAuthentication(jwtOptions);

                {

                    {
                        context.Skip();
                        return Task.FromResult(0);
                    },

                    OnGrantResourceOwnerCredentials = context =>
                    {
                        var identity = new ClaimsIdentity(context.Options.AuthenticationScheme);
                        identity.AddClaim(ClaimTypes.NameIdentifier, "[unique id]");

                        identity.AddClaim("urn:customclaim", "value", OpenIdConnectConstants.Destinations.AccessToken, OpenIdConnectConstants.Destinations.IdentityToken);

                        var ticket = new AuthenticationTicket(
                            new ClaimsPrincipal(identity),
                            new Microsoft.AspNetCore.Http.Authentication.AuthenticationProperties(),
                            context.Options.AuthenticationScheme);

                        ticket.SetScopes("profile", "offline_access");

                        context.Validate(ticket);

                        return Task.FromResult(0);
                    }
                };
            });            

            app.UseMvc();
        }

发送 x-url 编码的 POST 到 http://localhost:5000使用 grant_type=password、username=foo、password=bar 生成预期的 access_token。

我添加了 [Authorize("Bearer")]属性到 ValuesController 并且这在调用 JwtBearerMiddlewear 时按预期工作，但我无法获取 token 进行验证。

有没有人在.net core RC2 上工作过？我在 RC1 上也有同样的工作，但一直无法做到这一点。

谢谢。

从 beta5 开始(用于 ASP.NET Core RC2)，the OpenID Connect server middleware no longer uses JWT as the default format for access tokens .相反，它使用不透明的 token ，由坚如磐石的 ASP.NET Core 数据保护堆栈加密(就像身份验证 cookie)。

您有 3 个选项来修复您看到的错误:

使用 new OAuth2 validation middleware开发以支持不透明 token ( 推荐选项 ，如果您的 API 和授权服务器是同一应用程序的一部分)。为此，请保留 AspNet.Security.OAuth.Validation您在 project.json 中的引用资料并替换 app.UseJwtBearerAuthentication(...)通过 app.UseOAuthValidation() .您也可以删除 Microsoft.AspNetCore.Authentication.JwtBearer来自 project.json .

通过调用 options.AccessTokenHandler = new JwtSecurityTokenHandler(); 强制 OpenID Connect 服务器中间件使用 JWT token 在选项中。请注意，您还必须调用 ticket.SetResources(...)使用 JWT token 附加适当的受众(参见其他 SO post 了解更多信息)。

使用 new introspection middleware .此选项更复杂，需要实现 ValidateIntrospectionRequest验证客户端凭据的事件。仅当您知道自己在做什么时才使用它。
