我提前道歉，因为我几乎不了解一般的安全性，特别是 IdentityServer。
我正在尝试设置 IdentityServer 来管理 Asp.Net MVC 应用程序的安全性。
我正在关注他们网站上的教程：Asp.Net MVC with IdentityServer
但是，我正在做一些稍微不同的事情，因为我有一个用于身份“服务器”部分的单独项目，该项目导致 2 个 Startup.cs 文件，一个用于应用程序，一个用于身份服务器
对于应用程序，Startup.cs 文件如下所示
public class Startup
{
public void Configuration(IAppBuilder app)
{
AntiForgeryConfig.UniqueClaimTypeIdentifier = Constants.ClaimTypes.Subject;
JwtSecurityTokenHandler.InboundClaimTypeMap = new Dictionary<string, string>();
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = "Cookies"
});
app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions
{
Authority = "https://localhost:44301/identity",
ClientId = "baseballStats",
Scope = "openid profile roles baseballStatsApi",
RedirectUri = "https://localhost:44300/",
ResponseType = "id_token token",
SignInAsAuthenticationType = "Cookies",
UseTokenLifetime = false,
Notifications = new OpenIdConnectAuthenticationNotifications
{
SecurityTokenValidated = async n =>
{
var userInfoClient = new UserInfoClient(
new Uri(n.Options.Authority + "/connect/userinfo"),
n.ProtocolMessage.AccessToken);
var userInfo = await userInfoClient.GetAsync();
// create new identity and set name and role claim type
var nid = new ClaimsIdentity(
n.AuthenticationTicket.Identity.AuthenticationType,
Constants.ClaimTypes.GivenName,
Constants.ClaimTypes.Role);
userInfo.Claims.ToList().ForEach(c => nid.AddClaim(new Claim(c.Item1, c.Item2)));
// keep the id_token for logout
nid.AddClaim(new Claim("id_token", n.ProtocolMessage.IdToken));
// add access token for sample API
nid.AddClaim(new Claim("access_token", n.ProtocolMessage.AccessToken));
// keep track of access token expiration
nid.AddClaim(new Claim("expires_at", DateTimeOffset.Now.AddSeconds(int.Parse(n.ProtocolMessage.ExpiresIn)).ToString()));
// add some other app specific claim
nid.AddClaim(new Claim("app_specific", "some data"));
n.AuthenticationTicket = new AuthenticationTicket(
nid,
n.AuthenticationTicket.Properties);
}
}
});
app.UseResourceAuthorization(new AuthorizationManager());
app.UseIdentityServerBearerTokenAuthentication(new IdentityServerBearerTokenAuthenticationOptions
{
Authority = "https://localhost:44301/identity",
RequiredScopes = new[] { "baseballStatsApi"}
});
var config = new HttpConfiguration();
config.MapHttpAttributeRoutes();
app.UseWebApi(config);
}
}
对于身份服务器，startup.cs 文件是
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.Map("/identity", idsrvApp =>
{
idsrvApp.UseIdentityServer(new IdentityServerOptions
{
SiteName = "Embedded IdentityServer",
SigningCertificate = LoadCertificate(),
Factory = InMemoryFactory.Create(
users: Users.Get(),
clients: Clients.Get(),
scopes: Scopes.Get())
});
});
}
X509Certificate2 LoadCertificate()
{
return new X509Certificate2(
string.Format(@"{0}\bin\Configuration\idsrv3test.pfx", AppDomain.CurrentDomain.BaseDirectory), "idsrv3test");
}
}
我也在设置授权管理器
public class AuthorizationManager : ResourceAuthorizationManager
{
public override Task<bool> CheckAccessAsync(ResourceAuthorizationContext context)
{
switch (context.Resource.First().Value)
{
case "Players":
return CheckAuthorization(context);
case "About":
return CheckAuthorization(context);
default:
return Nok();
}
}
private Task<bool> CheckAuthorization(ResourceAuthorizationContext context)
{
switch(context.Action.First().Value)
{
case "Read":
return Eval(context.Principal.HasClaim("role", "LevelOneSubscriber"));
default:
return Nok();
}
}
}
例如，如果我定义了一个用 ResourceAuthorize 属性修饰的控制器方法，就像这样
public class HomeController : Controller
{
[ResourceAuthorize("Read", "About")]
public ActionResult About()
{
return View((User as ClaimsPrincipal).Claims);
}
}
然后，当我第一次尝试访问此方法时，我将被重定向到默认登录页面。
然而，我不明白的是，为什么当我使用为应用程序定义的用户登录时（见下文），
public class Users
{
public static List<InMemoryUser> Get()
{
return new List<InMemoryUser>
{
new InMemoryUser
{
Username = "bob",
Password = "secret",
Subject = "1",
Claims = new[]
{
new Claim(Constants.ClaimTypes.GivenName, "Bob"),
new Claim(Constants.ClaimTypes.FamilyName, "Smith"),
new Claim(Constants.ClaimTypes.Role, "Geek"),
new Claim(Constants.ClaimTypes.Role, "LevelOneSubscriber")
}
}
};
}
}
我收到 403 错误，Bearer error="insufficient_scope"。
谁能解释我做错了什么？
任何后续访问操作方法的尝试都将返回相同的错误。在我看来，我定义的用户拥有能够访问此方法的正确声明。但是，当我第一次尝试访问此方法时，声明检查只发生一次。登录后，我得到一个 cookie，并且在随后尝试访问该方法期间不会进行声明检查。
我有点迷茫，希望能得到一些帮助来解决这个问题。
提前致谢。
编辑：这里是分数和客户类
public static class Scopes
{
public static IEnumerable<Scope> Get()
{
var scopes = new List<Scope>
{
new Scope
{
Enabled = true,
Name = "roles",
Type = ScopeType.Identity,
Claims = new List<ScopeClaim>
{
new ScopeClaim("role")
}
},
new Scope
{
Enabled = true,
Name = "baseballStatsApi",
Description = "Access to baseball stats API",
Type = ScopeType.Resource,
Claims = new List<ScopeClaim>
{
new ScopeClaim("role")
}
}
};
scopes.AddRange(StandardScopes.All);
return scopes;
}
}
和客户端类
public static class Clients
{
public static IEnumerable<Client> Get()
{
return new[]
{
new Client
{
Enabled = true,
ClientName = "Baseball Stats Emporium",
ClientId = "baseballStats",
Flow = Flows.Implicit,
RedirectUris = new List<string>
{
"https://localhost:44300/"
}
},
new Client
{
Enabled = true,
ClientName = "Baseball Stats API Client",
ClientId = "baseballStats_Api",
ClientSecrets = new List<ClientSecret>
{
new ClientSecret("secret".Sha256())
},
Flow = Flows.ClientCredentials
}
};
}
}
我还创建了一个自定义过滤器属性，用于确定何时进行索赔检查。
public class CustomFilterAttribute : ResourceAuthorizeAttribute
{
public CustomFilterAttribute(string action, params string[] resources) : base(action, resources)
{
}
protected override bool CheckAccess(HttpContextBase httpContext, string action, params string[] resources)
{
return base.CheckAccess(httpContext, action, resources);
}
}
断点仅在对 url 的初始请求时被命中。在后续请求中，过滤器属性断点未命中，因此不进行检查。这让我感到惊讶，因为我认为每次请求 url 时都必须进行检查。
