IdentityServer, ASP.NET Core and Web API

我已经设置了IdentityServer4和另一个客户端ASP。. NET Core应用程序。客户端需要使用IdentityServer进行身份验证，并请求访问第三个应用程序，该应用程序是标准MVC Web API项目。

我遵循了这个示例中实现Client Credentials Flow的步骤https://identityserver.github.io/Documentation/docsv2/overview/simplestOAuth.html

现在我完全失去了如何让WEB API首先识别承载令牌，然后给我一些授权来访问WEB API端点。

这是我的IdentityServer statrupp .cs

public class Startup
{
    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
            .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);
        builder.AddEnvironmentVariables();
        Configuration = builder.Build();
    }
    public IConfigurationRoot Configuration { get; }
    // This method gets called by the runtime. Use this method to add services to the container
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddIdentityServer()
                .AddInMemoryStores()
                .AddInMemoryClients(Config.GetClients())
                .AddInMemoryScopes(Config.GetScopes());           
    }
    // 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)
    {
        loggerFactory.AddConsole(LogLevel.Debug);
        app.UseDeveloperExceptionPage();
        app.UseIdentityServer();
    }
}

和Config.cs

 public class Config
{
    // scopes define the resources in your system
    public static IEnumerable<Scope> GetScopes()
    {
        return new List<Scope>
        {
            new Scope
            {
                Name = "api1"
            }
        };
    }
    // clients want to access resources (aka scopes)
    public static IEnumerable<Client> GetClients()
    {
        // client credentials client
        return new List<Client>
        {
            // no human involved
        new Client
        {
            ClientName = "Silicon-only Client",
            ClientId = "silicon",
            Enabled = true,
            AccessTokenType = AccessTokenType.Reference,
            AllowedGrantTypes = GrantTypes.ClientCredentials,
            ClientSecrets = new List<Secret>
            {
                new Secret("F621F470-9731-4A25-80EF-67A6F7C5F4B8".Sha256())
            },
            AllowedScopes = new List<string>
            {
                "api1"
            }
        }
        };
    }}

ASP。. NET核心对IdentityServer和Web API的调用

[Route("api/testing")]
    public class TestingController : Controller
    {
        // GET: api/values
        [HttpGet]
        public IActionResult Get()
        {
            var responce = GetClientToken();
            return Json(new
            {
                message = CallApi(responce)
            });
        }
        static TokenResponse GetClientToken()
        {
            var client = new TokenClient(
                Constants.TokenEndpoint,
                "silicon",
                "F621F470-9731-4A25-80EF-67A6F7C5F4B8");
            return client.RequestClientCredentialsAsync("api1").Result;
        }
        static string CallApi(TokenResponse response)
        {
            var client = new HttpClient
            {
                BaseAddress = new Uri(Constants.AspNetWebApiSampleApi),
                Timeout = TimeSpan.FromSeconds(10)
            };
            client.SetBearerToken(response.AccessToken); 
            try
            {                  
                var auth = client.GetStringAsync().Result;
                return auth;
            }
            catch (Exception ex)
            {
                return ex.Message;
            }
        }  
    }

所以谁能解释或分享一些链接，我应该做些什么来获得WEB APi(与自己的中间件)来处理来自ASP的调用。. NET Core客户端?我应该把什么设置在Owin配置(IAppBuilder应用程序)方法。

new Scope
{
    Name = "api",
    DisplayName = "Your scopes display name",
    Type = ScopeType.Resource,
    Claims = new List<ScopeClaim>
    {
        new ScopeClaim("role")
    }
}

app.UseIdentityServerBearerTokenAuthentication(
    new IdentityServerBearerTokenAuthenticationOptions
    {
        Authority = "YourIdentityServersAddress.com/identity",
        RequiredScopes = new[] { "api" },
     });
 app.UseWebApi(WebApiConfig.Register());

app.UseResourceAuthorization(new AuthorizationManager());
