Angular AWS cognito刷新标记问题在具有角度的星云中

我的JWT令牌刷新有问题，如果令牌在未登录的情况下过期，我需要刷新令牌， 我在NbAuthService中看到一个名为refreshToken的方法。 我不明白如何使用它，我在拦截器中添加了代码。这是我的密码 在这段代码中，它不是订阅refreshToken

@Injectable()
export class AuthJWTInterceptor implements HttpInterceptor {
  constructor(private injector: Injector, private router: Router) {}

  intercept(
    req: HttpRequest<any>,
    next: HttpHandler,
  ): Observable<HttpEvent<any>> {
    return this.authService.getToken().switchMap((token: NbAuthJWTToken) => {
      if (!token.isValid()) {
         this.authService.refreshToken('email').subscribe((newToken: any) => {
          console.log((newToken));
        });
        this.router.navigate(['auth']);
      }
      if (token) {
        const JWT = `${token.getValue()}`;
        req = req.clone({
          setHeaders: {
            Authorization: JWT,
          },
        });
      }
      return next.handle(req);
    });
  }

  protected get authService(): NbAuthService {
    return this.injector.get(NbAuthService);
  }
}
