OIDC in Angular 6

 参照 草根专栏- ASP.NET Core + Ng6 实战：https://v.qq.com/x/page/i07702h18nz.html

1、 OIDC-Client

          https://github.com/IdentityModel/oidc-client-js

          npm install oidc-client --save

2、建立   open-id-connect.service.ts   

        ng g s shared/oidc/openIdConnect

3、 environment,配置oidc客户端

export const environment = {
  production: false ,
  apiUrlBase: '/api',
  openIdConnectSettings: {
    authority: 'https://localhost:5001/',
    client_id: 'blog-client',
    redirect_uri: 'http://localhost:4200/signin-oidc',
    scope: 'openid profile email restapi',
    response_type: 'id_token token',
    post_logout_redirect_uri: 'http://localhost:4200/',
    automaticSilentRenew: true,
    silent_redirect_uri: 'http://localhost:4200/redirect-silentrenew'
  }
};

4、BlogIdp项目，config.cs 文件配置客户端访问：

                // Angular client using implicit flow
                new Client
                {
                    ClientId = "blog-client",
                    ClientName = "Blog Client",
                    ClientUri = "http://localhost:4200",

                    AllowedGrantTypes = GrantTypes.Implicit,
                    AllowAccessTokensViaBrowser = true,
                    RequireConsent = false,
                    AccessTokenLifetime = 180,

                    RedirectUris =
                    {
                        "http://localhost:4200/signin-oidc",
                        "http://localhost:4200/redirect-silentrenew"
                    },

                    PostLogoutRedirectUris = { "http://localhost:4200/" },
                    AllowedCorsOrigins = { "http://localhost:4200" },

                    AllowedScopes = {
                        IdentityServerConstants.StandardScopes.OpenId,
                        IdentityServerConstants.StandardScopes.Profile,
                        IdentityServerConstants.StandardScopes.Email,
                        "restapi" }
                }

5、Blogidp项目配置跨域：

            services.AddCors(options =>
            {
                options.AddPolicy("AngularDev", policy =>
                {
                    policy.WithOrigins("http://localhost:4200")
                        .AllowAnyHeader()
                        .AllowAnyMethod();
                });
            });

        public void Configure(IApplicationBuilder app)
        {
 
            app.UseCors();
 
        }

6、open-id-connect.service.ts 添加登陆操作：

import { Injectable } from '@angular/core';
import { UserManager, User } from 'oidc-client';
import { environment } from '../../../environments/environment';
import { ReplaySubject } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class OpenIdConnectService {

  private userManager: UserManager = new UserManager(environment.openIdConnectSettings);

  private currentUser: User;

  userLoaded$ = new ReplaySubject<boolean>(1);

  get userAvailable(): boolean {
    return this.currentUser != null;
  }

  get user(): User {
    return this.currentUser;
  }

  constructor() {
    this.userManager.clearStaleState();

    this.userManager.events.addUserLoaded(user => {
      if (!environment.production) {
        console.log('User loaded.', user);
      }
      this.currentUser = user;
      this.userLoaded$.next(true);
    });

    this.userManager.events.addUserUnloaded((e) => {
      if (!environment.production) {
        console.log('User unloaded');
      }
      this.currentUser = null;
      this.userLoaded$.next(false);
    });
  }

  triggerSignIn() {
    this.userManager.signinRedirect().then(() => {
      if (!environment.production) {
        console.log('Redirection to signin triggered.');
      }
    });
  }

  handleCallback() {
    this.userManager.signinRedirectCallback().then(user => {
      if (!environment.production) {
        console.log('Callback after signin handled.', user);
      }
    });
  }

  handleSilentCallback() {
    this.userManager.signinSilentCallback().then(user => {
      this.currentUser = user;
      if (!environment.production) {
        console.log('Callback after silent signin handled.', user);
      }
    });
  }

  triggerSignOut() {
    this.userManager.signoutRedirect().then(resp => {
      if (!environment.production) {
        console.log('Redirection to sign out triggered.', resp);
      }
    });
  }

}

7、添加  signin-oidc component 

8、添加 redirect-silent-renew component 

9、 ng g guard shared/oidc/RequireAuthenticatedUserRoute --spec false

        触发登陆界面；

        app.module  Provided  添加   RequireAuthenticatedUserRouteGuard ， OpenIdConnectService

10、blog-routing.module.ts 注册路由：

const routes: Routes = [
  {
    path: '', component: BlogAppComponent,
    children : [
      {path: 'post-list' , component: PostListComponent, canActivate: [RequireAuthenticatedUserRouteGuard] },
      {path: '**' , redirectTo: 'post-list' }
    ]
}

11、配置登陆路由： app.module

const routers: Routes = [
  { path: 'blog', loadChildren: './blog/blog.module#BlogModule' },
  { path: 'signin-oidc', component: SigninOidcComponent },
  { path: 'redirect-silentrenew', component: RedirectSilentRenewComponent },
  { path: '**', redirectTo: 'blog' }
];

12、添加拦截器：authorization-header-interceptor.interceptor.ts  ,在blog.module.ts 里面配置

  providers: [
    PostService,
    {
      provide: HTTP_INTERCEPTORS,
      useClass: AuthorizationHeaderInterceptor,
      multi: true
    }
  ]
