1. 在你的应用程序中创建一个AuthService来处理所有的身份验证逻辑：

import { Injectable } from '@angular/core'; import { HttpClient } from '@angular/common/http'; import { BehaviorSubject } from 'rxjs'; import { tap } from 'rxjs/operators';

@Injectable({ providedIn: 'root' }) export class AuthService { private readonly tokenUrl = '/api/auth/token'; private readonly tokenKey = 'auth-token'; private authToken$ = new BehaviorSubject(null);

constructor(private http: HttpClient) { this.loadToken(); }

private loadToken() { const token = localStorage.getItem(this.tokenKey); this.authToken$.next(token); }

getAuthToken() { return this.authToken$.value; }

setAuthToken(token: string) { localStorage.setItem(this.tokenKey, token); this.authToken$.next(token); }

login(username: string, password: string) { return this.http.post(this.tokenUrl, { username, password }) .pipe( tap((data: { token: string }) => this.setAuthToken(data.token)) ); }

logout() { localStorage.removeItem(this.tokenKey); this.authToken$.next(null); }

isAuthenticated() { return !!this.authToken$.value; } }

2. 在你的AppComponent中调用AuthService的login方法以获取Token：

import { Component } from '@angular/core'; import { AuthService } from './auth.service';

@Component({ selector: 'app-root', template: }) export class AppComponent { constructor(private authService: AuthService) {}

ngOnInit() { this.authService.login('your-username', 'your-password').subscribe(); } }

3. 在Http请求时使用Bearer Token：

import { Injectable } from '@angular/core'; import { HttpClient, HttpHeaders } from '@angular/common/http'; import { AuthService } from './auth.service';

@Injectable({ providedIn: 'root' }) export class DataService { constructor(private http: HttpClient, private authService: AuthService) {}

getData() { const headers = new HttpHeaders().set('Authorization', Bearer ${this.authService.getAuthToken()}); return this.http.get('/api/data', { headers }); } }

这样做可以在页面加载时自动获取Token，并将其存储在localStorage中。在您的应用程序中的任何Http
