How to bring token and visit other pages after login? Angula

I would like to log in pages with `token` from a backend server written in Django (JWT token), I finally got a 200 in `login router` according this [angular-7-jwt-authentication-example-tutorial][1], but after login, I don't know how to bring this token and visit other pages, add `currentUser` to recognize or import some files? Really stuck in this issue.
Any advices will be highly appreciated.

Partial code of `auth.service.ts` as below:

    import { Inject, Injectable } from '@angular/core';
    import { HttpHeaders, HttpClient, HttpParams } from '@angular/common/http';
    import { BehaviorSubject, Observable, throwError } from 'rxjs';
    import { Auth, User } from '../domain';
    import { map, switchMap } from 'rxjs/operators';

    @Injectable({ providedIn: 'root' })
    export class AuthService {
        private currentUserSubject: BehaviorSubject<Auth>;
        public currentUser: Observable<Auth>;

        constructor(
          private http: HttpClient,
          @Inject('BASE_CONFIG') private config: { uri: string }
        ) {
            this.currentUserSubject = new BehaviorSubject<Auth>(JSON.parse(localStorage.getItem('currentUser') || '{}'));
            this.currentUser = this.currentUserSubject.asObservable();
        }

        public get currentUserValue(): Auth {
            return this.currentUserSubject.value;
        }

        login(email: string, password: string): Observable<Auth> {
            return this.http.post<any>(`${this.config.uri}/users`, { email, password })
                .pipe(map(user => {
                    // login successful if there's a jwt token in the response
                    if (user && user.token) {
                        // store user details and jwt token in local storage to keep user logged in between page refreshes
                        localStorage.setItem('currentUser', JSON.stringify(user));
                        this.currentUserSubject.next(user);
                    }

                    return user;
                }));
        }

partial code of `project.service.ts` as below:

      // GET /projects
      get(username: string): Observable<Project[]> {
        const uri = `${this.config.uri}/projects`;
        // const uri = `${this.config.uri}/project/`;
        const params = new HttpParams().set('members_like', username);
        return this.http.get<Project[]>(uri, {
          params: params,
          headers: this.headers
        });
      }
