Angular 4 / Angular 2针对Azure B2C Active Directory验证SPA

Question

In Angular 4/Angular 2 app, I want to validate it against Azure B2C Active Directory. In ASP.NET MVC, it was done using [Authorize] attribute on Controller and using an OWIN Startup.cs class to generate the authentication challenge and generating the Bearer token.

Moving on to a SPA application using Angular 4/Angular 2, I am not able to find a relevant tutorial for the same. I have seen some examples using Auth0, but I am not looking for an Auth0 solution. I want to authenticate directly against the Azure B2C Active Directory.

Can some approach and relevant example and tutorial describing the same be provided.

Tried ng2-adal sample suggested by 'Fei Xue - MSFT' below. Adding ng2-adal sample error message pics.

Added 'package.json' code:-

AFAIK, we need to implement CanActivate interface in the Angular 2 for the guard deciding if a route can be activated.

To protect the SPA for the Angular 2 using Azure AD you can refer this code sample . And about the Azure AD B2C authentication, you can refer this document .
