azure - 未为受 Azure Active Directory 保护的 Azure WebApp 调用 OpenIdConnectAuthenticationNotifications.AuthorizationCodeReceived 事件

Question

我的 MVC WebApp 已部署到 Azure Paas 并使用 Azure AD 进行保护。身份验证设置使用下面的示例代码作为基础，它在本地主机中使用 IISExpress 或 IIS 运行。

https://github.com/Azure-Samples/active-directory-dotnet-webapp-webapi-openidconnect

但部署到 Azure 后无法正常工作。即使用户能够正确进行身份验证，也永远不会调用 AuthorizationCodeReceived 委托(delegate)。

这是设置身份验证的启动代码:

void ConfigureAuth(IAppBuilder app,  Container container) {
        _log.Debug("Configuring Azure Authentication");

        AzureActiveDirectoryAppSetting setting = container.GetInstance<IAzureActiveDirectoryAppSettingFactory>().Get();
        app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
        app.UseCookieAuthentication(new CookieAuthenticationOptions());
        app.UseOpenIdConnectAuthentication(
            new OpenIdConnectAuthenticationOptions() {
                ClientId = setting.ClientID,
                Authority = setting.Authority,
                PostLogoutRedirectUri = setting.PostLogoutRedirectUrl,
                RedirectUri = setting.ReplyUrl,
                Notifications = new OpenIdConnectAuthenticationNotifications() {
                    AuthorizationCodeReceived = new Func<Microsoft.Owin.Security.Notifications.AuthorizationCodeReceivedNotification, System.Threading.Tasks.Task>(args => OnAuthorizationCodeReceived(args, container)),
                    AuthenticationFailed = new Func<Microsoft.Owin.Security.Notifications.AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions>, System.Threading.Tasks.Task>(OnAuthorizationFailed),
                }
            }
        );
    }

    System.Threading.Tasks.Task OnAuthorizationFailed(Microsoft.Owin.Security.Notifications.AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> args) {
        _log.Error("Authorization Failed");
        return System.Threading.Tasks.Task.FromResult<string>(null);
    }
    System.Threading.Tasks.Task OnAuthorizationCodeReceived(Microsoft.Owin.Security.Notifications.AuthorizationCodeReceivedNotification args, Container container) {
        _log.Debug("Authorization Code Received");
        var auth =  container.GetInstance<IClaimsBasedAuthentication>();
        return auth.ReceiveSecurityClaim(args.Code, args.AuthenticationTicket.Identity, HttpContext.Current);
    }

这是来自 Azure 的跟踪。如您所见，身份验证成功，但找不到“授权失败”或“已收到授权码”跟踪信息。第一个错误来自 AcquireTokenSilentAsync 调用。它失败了，因为 token 一开始就没有缓存。

感谢任何帮助。谢谢!

编辑以澄清标记的答案:

正如 Nan Yu 所说，当启用“身份验证/授权”功能时，可能会重复出现此问题。工作设置如下图所示。

1. 确保“应用服务身份验证”已开启
2. 请求未经身份验证时采取的操作:允许匿名请求(无操作)这就是我被困了一个月的原因。我在“使用 Azure Active Directory 登录”中看到了此内容
3. 正确配置 Azure Active Directory。您可以在教程中找到此信息。

Answer 1

根据回复网址:https://albatrossweb.azurewebsites.net/.auth/login/aad/callback/ ，看来您启用了azure应用程序服务的“身份验证/授权”功能。我可以重现，如果我启用“身份验证/授权”功能，在这种情况下，简单的身份验证将接管身份验证过程。如果您启用了应用服务的“身份验证/授权”，请尝试禁用它并重试。
