Question

我有两个用.NET Core编写的api，目标是4.6.1：

myAuthApi（http://localhost:8496）：用于验证凭据并向客户发放令牌。它还有一个端点/ api / values / 1（此操作的Authorize属性，用于验证令牌）
myPublicApi（http://localhost:8497）：在/ api / values / 1上接收来自客户端的令牌（此操作的Authorize属性，也用于验证令牌）。 myPublicApi没有任何令牌端点，并且是资源服务器。

我使用的是AspNet.Security.OpenIdConnect.Server 1.0.0。这两个API都是Service.Fabric无状态服务

我可以使用以下请求格式成功获取令牌http://localhost:8496/connect/token

client_id=XX&client_secret=XXX&grant_type=password&username=XXX&password=XXX

在针对myAuthApi（http://localhost:8496/api/values/1）验证令牌时，它可以正常工作。但是，当对myPublicApi（http://localhost:8497/api/values/1）使用相同的令牌时，它不会。

在两个API中，在Startup.cs中，我有

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        // Connect to Redis database.
        var redis = ConnectionMultiplexer.Connect(ConnectionHelper.GetRedisConnectionString(Configuration));
        services.AddDataProtection()
            .PersistKeysToRedis(redis, "DataProtection-Keys")
            .ProtectKeysWithCertificate(CertificateHandler.GetX509Certificate2(Configuration));

        // Add framework services.
        services.AddMvc().AddJsonOptions(opts =>
        {
            // we set the json serializer to follow camelCaseConventions when 
            // receiving /replying to JSON requests
            opts.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
        });
        // we add authentication for the oAuth middleware to be registered in the DI container
        services.AddAuthentication();
    }

在myPublicApi中，我有：

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {

        // Add a new middleware validating access tokens.
        app.UseOAuthValidation(options =>
        {
            // Automatic authentication must be enabled
            // for SignalR to receive the access token.
            options.AutomaticAuthenticate = true;
            options.Events = new OAuthValidationEvents
            {
                // Note: for SignalR connections, the default Authorization header does not work,
                // because the WebSockets JS API doesn't allow setting custom parameters.
                // To work around this limitation, the access token is retrieved from the query string.
                OnRetrieveToken = context =>
                {
                    // Note: when the token is missing from the query string,
                    // context.Token is null and the JWT bearer middleware will
                    // automatically try to retrieve it from the Authorization header.
                    context.Token = context.Request.Query["access_token"];

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

        app.UseMvc();
    }

在myAuthApi中我有：

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        // Add a new middleware validating access tokens.
        app.UseOAuthValidation(options =>
        {
            // Automatic authentication must be enabled
            // for SignalR to receive the access token.
            options.AutomaticAuthenticate = true;
            options.Events = new OAuthValidationEvents
            {
                // Note: for SignalR connections, the default Authorization header does not work,
                // because the WebSockets JS API doesn't allow setting custom parameters.
                // To work around this limitation, the access token is retrieved from the query string.
                OnRetrieveToken = context =>
                {
                    // Note: when the token is missing from the query string,
                    // context.Token is null and the JWT bearer middleware will
                    // automatically try to retrieve it from the Authorization header.
                    context.Token = context.Request.Query["access_token"];

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

        // Add a new middleware issuing access tokens.
        app.UseOpenIdConnectServer(options =>
        {
            options.Provider = new AuthenticationProvider();
            // Enable the logout, token and userinfo endpoints.
            options.LogoutEndpointPath = "/connect/logout";
            options.TokenEndpointPath = "/connect/token";
            options.UserinfoEndpointPath = "/connect/userinfo";
            CertificateHandler.SetupCommonAuthServerOptions(options, Configuration);
        });

        app.UseMvc();
    }

正如您所看到的，我的数据保护提供程序正在将密钥存储在Redis中，而我正在使用我在2个应用程序中共享的证书来保护密钥。资源服务器未配置任何身份验证提供程序，并且在启动时没有UseOpenIdConnectServer。在asp.net Web API 2中，令牌解密过去是使用共享机器密钥在应用程序之间进行管理的。

如何使用oAuthValidation在所有其他应用中成功验证myAuthApi发出的令牌？

EDIT2：在彻底阅读了日志之后，我发现令牌的不受保护是使用相同的数据保护提供程序，但用途不同：

"Performing unprotect operation to key {4406cfa7-a588-44ba-b73a-e25817d982d9} with purposes ('C:\SfDevCluster\Data\_App\_Node_4\TestMicroServicesType_App22\PublicApiPkg.Code.1.0.1', 'OpenIdConnectServerHandler', 'AccessTokenFormat', 'ASOS')."
"Performing unprotect operation to key {4406cfa7-a588-44ba-b73a-e25817d982d9} with purposes ('C:\SfDevCluster\Data\_App\_Node_3\TestMicroServicesType_App22\AuthApiPkg.Code.1.0.1', 'OpenIdConnectServerHandler', 'AccessTokenFormat', 'ASOS')."

要解决此问题，@ PinpointTownes建议设置数据保护提供程序，如下所示：

    var redis = ConnectionMultiplexer.Connect(ConnectionHelper.GetRedisConnectionString(Configuration));
    services.AddDataProtection()
             // set the application name to a common value in all apps 
             // to have the same purpose and share the token across apps
            .SetApplicationName("MyTestMicroServices")
            .PersistKeysToRedis(redis, "DataProtection-Keys")
            .ProtectKeysWithCertificate(CertificateHandler.GetX509Certificate2(Configuration));

Answer 1

调用services.AddDataProtection().SetApplicationName("[your application name]")以确保您的两个API使用相同的鉴别器（用于派生加密密钥），它应该可以工作。
