Ero*_*ano 3 google-authentication firebase firebase-authentication angular
技术:框架:Angular,组件:Ionic,Auth-Service:Firebase,NPM-Module:https : //www.npmjs.com/package/@angular/fire
情况:用户可以通过用户名和密码登录,也可以使用 Google Auth 登录。当用户登录时,一些 cookie 会存储在浏览器中。
按照这里的要求是我用来登录的代码:
登录
loginWithGoogle() {
from(this.authService.logIn())
.pipe(
concatMap(() => this.authService.getAuth().signInWithPopup(new auth.GoogleAuthProvider())),
concatMap(userCredential => this.initStateAndRoute(userCredential)),
)
.subscribe();
}

认证服务
export class AuthService {
constructor(
private fireAuth: AngularFireAuth,
) {
}
getUser(): Observable<firebase.User> {
return this.fireAuth.user;
}
logOut() {
return this.fireAuth.auth.signOut();
}
getAuth() {
return this.fireAuth.auth;
}
logIn() {
return this.fireAuth.auth.setPersistence(firebase.auth.Auth.Persistence.LOCAL);

Auth-Guard-Service
@Injectable({
providedIn: 'root'
})
export class AuthGuardService implements CanActivate {
constructor(
private authService: AuthService,
private router: Router,
) {
}
canActivate(
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot
): Observable<boolean | UrlTree> | Promise<boolean | UrlTree> | boolean | UrlTree {
if (this.authService.getAuth().currentUser) {
return true;
}
this.router.navigateByUrl('login');
return false;
}

问题:当网站刷新时,所有这些 cookie 都会丢失,用户会自动注销。
我希望用户即使在刷新站点时也能保持登录状态。我错过了什么?
如果您的问题是即使用户在刷新后已登录,守卫仍将用户引导至登录页面,那么我建议使用 AngularFireAuthGuard 而不是常规的 Angular 守卫。
您基本上可以将其实现到您的 app-routing.module 中,它会为您处理一切。此外,通过使用它,您不再需要 Auth-Guard-Service。
一个非常简单的例子:
进入 app.module:
import { AngularFireAuthGuardModule } from '@angular/fire/auth-guard';
@NgModule({
declarations: [],
imports: [
AngularFireAuthGuardModule,
],
providers: [],
bootstrap: []
})

并进入 app-routing.module:
import { AngularFireAuthGuard, redirectUnauthorizedTo, redirectLoggedInTo } from '@angular/fire/auth-guard';
const redirectUnauthorizedToHome = () => redirectUnauthorizedTo(['home']);
const redirectLoggedInToAccount = () => redirectLoggedInTo(['my-account']);
const routes: Routes = [
{ path: 'my-account', component: MyAccountComponent, canActivate: [AngularFireAuthGuard], data: { authGuardPipe: redirectUnauthorizedToHome } },
{ path: 'create-account', component: CreateAccountComponent, canActivate: [AngularFireAuthGuard], data: { authGuardPipe: redirectLoggedInToAccount } },
];
