重定向后保留尝试的URL参数

在Angular项目中,我只是实现了Amazon Cognito托管的UI来处理我的登录:

现在,当我的用户单击我的登录按钮时,他们会被重定向到另一个URL https://[domain].amazoncognito.com/login?redirect_uri=http://localhost:4200/&response_type=code&client_id=[some id] 登录并重定向回我的角度URL以防成功。

已存储尝试的URL并在登录后重新定向 . 因为我只是有角度,所以一切都很顺利。

我的问题:

更多信息

这是调用我的Cognito托管UI的组件的摘录:

导航栏.component.ts

@Component({
  selector: 'app-navbar',
  templateUrl: './navbar.component.html',
  styleUrls: ['./navbar.component.scss']
})
export class NavbarComponent implements OnDestroy, OnInit {

  [...]

  constructor(
    @Inject(LOCALE_ID) protected localeId: string,
    private router: Router,
    private authService: AuthService,
    private usersService: UsersService
  ) { }

  [...]

  signIn() {
    this.authService.signIn();
  }

导航栏.component.html

<div class="navbar-item" *appShowIfSignedIn="false">
  <a class="button" (click)="signIn()">Sign in</a>
</div>

以下是我的AuthService摘录:

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

  private url = 'https://' + '[domain].auth.eu-central-1.amazoncognito.com' + '/login?redirect_uri=' + 'http://localhost:4200/' + '&response_type=' + 'code' + '&client_id=' + '[some id]';

  constructor(
    private ngZone: NgZone,
    private authStore: AuthStore
  ) {
    Hub.listen('auth', this, 'AuthCodeListener');
  }

  onHubCapsule(capsule: any) {
    const { channel, payload } = capsule;
    if (channel === 'auth' && payload.event === 'signIn') {
      this.ngZone.run(() => {
        this.currentAuthenticatedUser().subscribe(
          (user: any) => {
            const isSignedIn = true;
            const accessToken = user.signInUserSession.accessToken.jwtToken;
            const sub = user.signInUserSession.accessToken.payload['sub'];
            this.authStore.update({
              signedIn: isSignedIn,
              accessToken: accessToken,
              sub: sub
            });
          }
        );
      });
    }
  }

  signIn() {
    window.location.assign(this.url);
  }

谢谢你的帮助
