Question

我正在使用带有.Net Core 2.0和Asp.Net核心身份的IdentityServer4（v2.2.1）。我的解决方案中有三个项目。

IdentityServer
Web API
MVC Web应用程序

我正在尝试在我的Web API上实现基于角色的授权，以便任何客户端都可以将访问令牌传递给Web API以访问资源。

目前我可以在MVC应用程序控制器上实现Roles base授权，但我无法为WEB API Controller传递/配置相同的内容。

以下是Identity Server文件： Config.cs

public static IEnumerable<ApiResource> GetApiResources()
    {
        return new List<ApiResource>
        {
            //SCOPE - Resource to be protected by IDS 
            new ApiResource("TCSAPI", "TCS API")
            {
                UserClaims = { "role" }
            }
        };
    }


 public static IEnumerable<Client> GetClients()
    {
        return new List<Client>
        {
new Client
            {
                ClientId = "TCSIdentity",
                ClientName = "TCS Mvc Client Application .",
                AllowedGrantTypes = GrantTypes.HybridAndClientCredentials,
                RequireConsent = false,
                ClientSecrets =
                {
                    new Secret("secret".Sha256())
                },

                RedirectUris = { "http://localhost:5002/signin-oidc" },
                PostLogoutRedirectUris = { "http://localhost:5002/signout-callback-oidc" },

                AlwaysSendClientClaims= true,
                AlwaysIncludeUserClaimsInIdToken = true,

                AllowedScopes =
                {
                    IdentityServerConstants.StandardScopes.OpenId,
                    IdentityServerConstants.StandardScopes.Email,
                    IdentityServerConstants.StandardScopes.Profile,
                    IdentityServerConstants.StandardScopes.OfflineAccess,
                    "TCSAPI",
                    "office",
                    "role",
                },
                AllowOfflineAccess = true
            }
  };
    }

public static IEnumerable<IdentityResource> GetIdentityResources()
    {
        return new IdentityResource[]
        {
            new IdentityResources.OpenId(),
            new IdentityResources.Profile(),
            new IdentityResources.Email(),
            new IdentityResource
            {
                Name = "role",
                DisplayName="User Role",
                Description="The application can see your role.",
                UserClaims = new[]{JwtClaimTypes.Role,ClaimTypes.Role},
                ShowInDiscoveryDocument = true,
                Required=true,
                Emphasize = true
            }
        };
    }

Startup.cs

 public void ConfigureServices(IServiceCollection services)
    {
        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

        services.AddIdentity<ApplicationUser, IdentityRole>()
            .AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders();

        // Add application services.
        services.AddTransient<IEmailSender, EmailSender>();

        services.AddMvc();

        // configure identity server with in-memory stores, keys, clients and scopes
        services.AddIdentityServer()
            .AddDeveloperSigningCredential()
            .AddInMemoryPersistedGrants()
            .AddInMemoryIdentityResources(Config.GetIdentityResources())
            .AddInMemoryApiResources(Config.GetApiResources())
            .AddInMemoryClients(Config.GetClients())
            .AddAspNetIdentity<ApplicationUser>();
    }

MVC WEB APP（角色基础授权适用于MVC WEB APP）：

RoleClaimAction.cs 使用此文件将角色添加到Identity。

internal class RoleClaimAction : ClaimAction
{
    public RoleClaimAction()
        : base("role", ClaimValueTypes.String)
    {
    }

    public override void Run(JObject userData, ClaimsIdentity identity, string issuer)
    {
        var tokens = userData.SelectTokens("role");
        IEnumerable<string> roles;

        foreach (var token in tokens)
        {
            if (token is JArray)
            {
                var jarray = token as JArray;
                roles = jarray.Values<string>();
            }
            else
                roles = new string[] { token.Value<string>() };

            foreach (var role in roles)
            {
                Claim claim = new Claim("role", role, ValueType, issuer);
                if (!identity.HasClaim(c => c.Subject == claim.Subject
                                         && c.Value == claim.Value))
                {
                    identity.AddClaim(claim);
                }
            }
        }
    }
}

MVC WEB APP / Startup.cs

 public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();

        JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();
        services.AddCors();
        services.AddAuthentication(options =>
        {
            options.DefaultScheme = "Cookies";
            options.DefaultChallengeScheme = "oidc";
        })
            .AddCookie("Cookies")
            .AddOpenIdConnect("oidc", options =>
            {
                options.SignInScheme = "Cookies";
                options.Authority = "http://localhost:5000";
                options.RequireHttpsMetadata = false;

                options.ClientId = "TCSIdentity";

                //HYBRID FLOW
                options.ClientSecret = "secret";

                options.ClaimActions.Add(new RoleClaimAction()); // <-- 

                options.ResponseType = "code id_token token";
                options.GetClaimsFromUserInfoEndpoint = true;
                options.Scope.Add("TCSAPI");
                options.Scope.Add("offline_access");
                //END HYBRID FLOW
                options.SaveTokens = true;
                options.Scope.Add("role");

                options.TokenValidationParameters.NameClaimType = "name";
                options.TokenValidationParameters.RoleClaimType = "role";
            });

    }

MVC WEB APP / HomeController.cs 这个动作方法适用于角色基础授权，但是当我尝试将令牌传递给Web Api以访问具有角色基本授权的任何事件时，它无法授权。例如 var content = await client.GetStringAsync（＆＃34; http://localhost:5001/user＆＃34;）;

[Authorize(Roles = "User")]
    [Route("user")]
    public async Task<IActionResult> UserAccess()
    {

        var tokenClient = new TokenClient("http://localhost:5000/connect/token", "RoleApi", "secret");
        var tokenResponse = await tokenClient.RequestClientCredentialsAsync("TCSAPI");

        var client = new HttpClient();
        client.SetBearerToken(tokenResponse.AccessToken);
        var content = await client.GetStringAsync("http://localhost:5001/user");

        ViewBag.Json = JArray.Parse(content).ToString();
        return View("json");
    }
    [Authorize(Roles = "Admin")]
    [Route("admin")]
    public async Task<IActionResult> AdminAccess()
    {
        var accessToken = await HttpContext.GetTokenAsync("id_token");

        var client = new HttpClient();
        client.SetBearerToken(accessToken);
        var content = await client.GetStringAsync("http://localhost:5001/admin");
        ViewBag.Json = JArray.Parse(content).ToString();
        return View("json");
    }

的WebAPI / Startup.cs

 public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvcCore()
            .AddAuthorization()
            .AddJsonFormatters();
        services.AddAuthentication("Bearer")
            .AddIdentityServerAuthentication(options =>
            {
                options.Authority = "http://localhost:5000";
                options.RequireHttpsMetadata = false;
                options.ApiName = "TCSAPI";
            });

        services.AddCors(options =>
        {
            options.AddPolicy("default", policy =>
            {
                policy.WithOrigins("http://localhost:5002")
                .AllowAnyHeader()
                .AllowAnyMethod();
            });
        });
    }

WEB API / TestController.cs

[Route("admin")]
    [Authorize(Roles = "Admin")]
    public IActionResult AdminAccess()
    {
        return new JsonResult(from c in User.Claims select new { c.Type, c.Value });
    }
    [Route("user")]
    [Authorize(Roles = "User")]
    public IActionResult UserAccess()
    {
        return new JsonResult(from c in User.Claims select new { c.Type, c.Value });
    }
    [AllowAnonymous]
    [Route("public")]
    public IActionResult PublicAccess()
    {
        return new JsonResult(from c in User.Claims select new { c.Type, c.Value });
    }

使用IdentityServer4进行基于角色的Web API授权
