Question

我尝试使用IdentityServer3和Client Credential流程设置一个简单示例。该示例包含一个控制台客户端，该客户端使用从IdentityServer接收的令牌调用Web API资源。 Web API和IdentityServer托管在IIS中。

我设法使用以下方式从IdentityServer获取令牌：

  var client = new TokenClient(
            "https://machine+domain/WebHostedId3/connect/token",
            "client",
            "secret");

但是当我尝试使用以下方法调用Web API时

 var client = new HttpClient();

 client.SetBearerToken(token);

 var response = client.GetStringAsync("http://localhost/WebHostedApi/api/products").Result;

我接收到401（响应状态代码并不表示成功：401（未经授权）。

IdentityServer的设置如下：

public class Clients
{
    public static List<Client> Get()
    {
        return new List<Client>
        {
            new Client
            {
                ClientName = "Client Credentials Flow Client",
                Enabled = true,
                ClientId = "client",
                AccessTokenType = AccessTokenType.Reference,
                ClientSecrets = new List<Secret>
                {
                    new Secret("secret".Sha256())
                },

                Flow = Flows.ClientCredentials,

                AllowedScopes = new List<string>
                {
                    "api"
                }
            }
        };
    }
}

public class Scopes
{
    public static IEnumerable<Scope> Get()
    {
        return new[]
            {
                new Scope
                {
                    Name = "api",
                    DisplayName = "API Scope",
                    Type = ScopeType.Resource,
                    Emphasize = false
                }
            };
    }
}

 public class Startup
 {
    public void Configuration(IAppBuilder appBuilder)
    {
        Log.Logger = new LoggerConfiguration()
            .WriteTo.Trace(outputTemplate: "{Timestamp} [{Level}] ({Name}){NewLine} {Message}{NewLine}{Exception}")
            .CreateLogger();

        var factory = new IdentityServerServiceFactory()
            .UseInMemoryUsers(new System.Collections.Generic.List<InMemoryUser>())
                    .UseInMemoryClients(Clients.Get())
                    .UseInMemoryScopes(Scopes.Get());

        var options = new IdentityServerOptions
        {
            Factory = factory,
        };

        appBuilder.UseIdentityServer(options);
    }
}

Web API：

public static class WebApiConfig
{
    public static HttpConfiguration Register()
    {
        var config = new HttpConfiguration();

        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
           name: "DefaultRouting",
           routeTemplate: "api/{controller}/{id}",
           defaults: new { id = RouteParameter.Optional }
           );

        // require authentication for all controllers
        config.Filters.Add(new AuthorizeAttribute());

        return config;
    }
}

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        Log.Logger = new LoggerConfiguration()
            .WriteTo.Trace(outputTemplate: "{Timestamp} [{Level}] ({Name}){NewLine} {Message}{NewLine}{Exception}")
            .CreateLogger();

        app.UseIdentityServerBearerTokenAuthentication(
            new IdentityServerBearerTokenAuthenticationOptions
            {
                Authority = "machine+domain:443",
                ValidationMode = ValidationMode.ValidationEndpoint,
                RequiredScopes = new[] { "api" }
            });

        app.UseWebApi(WebApiConfig.Register());
    }
}

用于SSL的证书是使用IIS创建自签名证书功能创建的，并连接到IdentityServer的https绑定。除了＆＃34;响应状态代码不表示成功：401（未授权）＆＃34;例外我无法找到更多细节。 IdentityServer的日志看起来不错。非常感谢帮助。

Answer 1

我知道答复很晚。尝试更新所有nugets，尤其是Newtonsoft.Json到8.0.3

Answer 2

对于非常晚的响应感到抱歉，但如果您在IdentityServer中启用完整日志记录，它几乎会告诉您问题所在。

更改

var options = new IdentityServerOptions
{
    Factory = factory,
};

到

var options = new IdentityServerOptions
{
  Factory = factory,                   
  LoggingOptions = new LoggingOptions
  {
      EnableWebApiDiagnostics = true,
      WebApiDiagnosticsIsVerbose = true,
      EnableHttpLogging = true,
      EnableKatanaLogging = true
  }
}

然后你会看到很多很好的调试信息，告诉你出了什么问题。

Answer 3

在您的WebAPI配置中，IdentityServerBearerTokenAuthenticationOptions中的属性Authority的值不正确。它必须是IdentityServer实例的基URI，即https://localhost/WebHostedId3，而不仅仅是localhost，localhost:443。

考虑到IdentityServer3默认需要TLS，那么您需要指定https方案，而不仅仅是http。

因此，只要您的IdentityServer基本URI为https://localhost/WebHostedId3，那么正确的设置将如下所示

app.UseIdentityServerBearerTokenAuthentication(
    new IdentityServerBearerTokenAuthenticationOptions
    {
        Authority = "https://localhost/WebHostedId3",
        ValidationMode = ValidationMode.ValidationEndpoint,
        RequiredScopes = new[] { "api" }
    });

401使用IdentityServer3调用Web API时未授权
