恐怕是 Z 计划。我不知道他们为什么不退回它,但它目前是marked as planned on their Feedback Portal (it's the highest rated item)。
这就是我的做法。在用户通过身份验证时查询组,您也可以按照自己的方式进行 - 只需在需要时查询。取决于您的用例。
public partial class Startup
{
public void ConfigureAuth(IAppBuilder app)
{
app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
app.UseKentorOwinCookieSaver();
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
LoginPath = new PathString("/account/unauthorised"),
CookieSecure = CookieSecureOption.Always,
ExpireTimeSpan = TimeSpan.FromMinutes(20),
SlidingExpiration = true,
CookieHttpOnly = true
});
// Configure OpenID Connect middleware for each policy
app.UseOpenIdConnectAuthentication(CreateOptionsFromPolicy(Globals.SignInPolicyId));
}
private OpenIdConnectAuthenticationOptions CreateOptionsFromPolicy(string policy)
{
return new OpenIdConnectAuthenticationOptions
{
// For each policy, give OWIN the policy-specific metadata address, and
// set the authentication type to the id of the policy
MetadataAddress = string.Format(Globals.AadInstance, Globals.TenantName, policy),
AuthenticationType = policy,
AuthenticationMode = AuthenticationMode.Active,
// These are standard OpenID Connect parameters, with values pulled from web.config
ClientId = Globals.ClientIdForLogin,
RedirectUri = Globals.RedirectUri,
PostLogoutRedirectUri = Globals.RedirectUri,
Notifications = new OpenIdConnectAuthenticationNotifications
{
AuthenticationFailed = AuthenticationFailed,
SecurityTokenValidated = SecurityTokenValidated
},
Scope = "openid",
ResponseType = "id_token",
// This piece is optional - it is used for displaying the user's name in the navigation bar.
TokenValidationParameters = new TokenValidationParameters
{
NameClaimType = "name",
}
};
}
private async Task SecurityTokenValidated(SecurityTokenValidatedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> token)
{
var groups = await _metaDataService.GetGroups(token.AuthenticationTicket.Identity.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier").Value);
if (groups?.Value != null && groups.Value.Any())
{
foreach (IGroup group in groups.Value.ToList())
{
token.AuthenticationTicket.Identity.AddClaim(
new Claim(ClaimTypes.Role, group.DisplayName, ClaimValueTypes.String, "GRAPH"));
}
}
}
// Used for avoiding yellow-screen-of-death
private Task AuthenticationFailed(AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> notification)
{
notification.HandleResponse();
if (notification.Exception.Message == "access_denied")
{
notification.Response.Redirect("/");
}
else
{
notification.Response.Redirect("/error?message=" + notification.Exception.Message);
}
return Task.FromResult(0);
}
}
我的GetGroups 方法只是查询getMemberGroups method on the Users API
然后我有一个简单的辅助方法来判断用户是否是角色:
public static bool UserIsInRole(IPrincipal user, string roleName)
{
var claims = user.Identity as ClaimsIdentity;
if (claims == null) return false;
return claims.FindAll(x => x.Type == ClaimTypes.Role).Any(x => x.Value == roleName);
}
