使用asp.net身份在身份服务器4中实现角色

Question

我正在使用身份服务器4作为令牌服务的asp.net MVC应用程序.我有一个api,它有一些安全的资源.我想为api实现角色(授权).我想确保只有具有有效角色的授权资源才能访问api端点,否则会获得401(未经授权的错误).

这是我的配置:

客户

         new Client()
            {
                ClientId = "mvcClient",
                ClientName = "MVC Client",                    
                AllowedGrantTypes = GrantTypes.HybridAndClientCredentials,

                ClientSecrets = new List<Secret>()
                {
                    new Secret("secret".Sha256())
                },

                RequireConsent = false;

                // where to redirect to after login
                RedirectUris = { "http://localhost:5002/signin-oidc" },
                // where to redirect to after logout
                PostLogoutRedirectUris = { "http://localhost:5002" },

                AllowedScopes =
                {
                    StandardScopes.OpenId.Name,
                    StandardScopes.Profile.Name,
                    StandardScopes.OfflineAccess.Name,
                    StandardScopes.Roles.Name,
                    "API"
                }
            }

领域

 return new List<Scope>()
            {
                StandardScopes.OpenId, // subject id
                StandardScopes.Profile, // first name, last name
                StandardScopes.OfflineAccess,  // requesting refresh tokens for long lived API access
               StandardScopes.Roles,
                new Scope()
                {
                    Name = "API",
                    Description = "API desc",
                     Type = ScopeType.Resource,
                    Emphasize = true,
                    IncludeAllClaimsForUser = true,
                    Claims = new List<ScopeClaim>
                    {
                        new ScopeClaim(ClaimTypes.Name),      
                        new ScopeClaim(ClaimTypes.Role)
                    }
                }
            };

用户

new InMemoryUser()
                {
                    Subject = "1",
                    Username = "testuser",
                    Password = "password",
                    Claims = new List<Claim>()
                    {
                        new Claim("name", "Alice"),
                        new Claim("Website", "http://alice.com"),
                         new Claim(JwtClaimTypes.Role, "admin")

                    }
                }

在服务器启动中我添加了这个:

services.AddIdentityServer().AddTemporarySigningCredential().AddSigningCredential(cert).AddInMemoryClients(Config.GetClients()).AddInMemoryScopes(Config.GetScopes()).AddInMemoryUsers(Config.GetUsers())

在api启动中,我有这个:

  app.UseIdentityServerAuthentication(new IdentityServerAuthenticationOptions()
            {
                Authority = "http://localhost:5000",
                ScopeName = "NamfusAPI",
                RequireHttpsMetadata = false
            });

在api控制器中,我有这个:

 [Authorize(Roles = "admin")]
        public IActionResult Get()
        {
            return new JsonResult(from c in User.Claims select new {c.Type, c.Value });
        }

在MVC客户端启动中,我有这个:

 JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();

 app.UseCookieAuthentication(new CookieAuthenticationOptions()
            {
                AuthenticationScheme = "Cookies"
            });


            var oidcOptions = new OpenIdConnectOptions()
            {
                AuthenticationScheme = "oidc",
                SignInScheme = "Cookies",

                Authority = "http://localhost:5000",
                RequireHttpsMetadata = false,

                ClientId = "mvcClient",
                ClientSecret = "secret",
                SaveTokens = true,
                GetClaimsFromUserInfoEndpoint = true,
                ResponseType = "code id_token", // hybrid flow

            };


            oidcOptions.Scope.Clear();
            oidcOptions.Scope.Add("openid");
            oidcOptions.Scope.Add("profile");
            oidcOptions.Scope.Add("NamfusAPI");
            oidcOptions.Scope.Add("offline_access");
            oidcOptions.Scope.Add("roles");

我试着像这样调用api:

public async Task<IActionResult> CallApiUsingUserAccessToken()
        {
            var accessToken = await HttpContext.Authentication.GetTokenAsync("access_token");

            var client = new HttpClient();
            client.SetBearerToken(accessToken);
            var content = await client.GetStringAsync("http://localhost:5001/identity");

            ViewBag.Json = JArray.Parse(content).ToString();
            return View("json");
        } 

我获得访问令牌,但是当调用api(身份/获取)时,我得到302错误禁止(在chrome网络中它显示500内部服务器错误).如果我更改了API Authorize属性

  [Authorize(Roles = "admin")]
            public IActionResult Get()

到(没有角色):

 [Authorize]
        public IActionResult Get()

它工作,我从mvc应用程序中的api获取数据.如何在此代码中应用角色.

请建议.

Answer 1

首先,您需要在OpenIdConnectOptions()中请求"API"范围.

oidcOptions.Scope.Add("API");

要么

Scope = { "API", "offline_access",..},

然后,您需要检查角色声明是否包含在API控制器可用的声明列表中(不要在authorize属性中应用角色过滤器.在控制器方法中放置一个调试点并展开User属性).检查您收到的角色声明的类型(在声明集合中列出)是否与User.Identity.RoleClaimType属性匹配

如果您拥有User.Identity.RoleClaimType且不匹配的角色声明类型,则使用角色过滤器的authorize属性将不起作用.您可以RoleClaimType在IdentityServerAuthenticationOptions()中设置正确,如下所示

app.UseIdentityServerAuthentication(new IdentityServerAuthenticationOptions
        {
            Authority = "http://localhost:5000",
            ScopeName = "API",
            RoleClaimType = ClaimTypes.Role,
            RequireHttpsMetadata = false
        });
