重定向到 auth 路由的问题 Angular
Problems to redirect to auth route Angular
我开始与 Angular 合作,我正在尝试创建一个简单的路由保护,以在我的服务 return 未经授权的情况下将用户重定向到登录页面。
为此,我创建了这个路由模式 ->
const routes: Routes = [
{
path: '',
component: LoggedComponent,
children: [
{path: '', component: HomeComponent}
],
canActivate: [RouteGuard]
},
{
path: '',
component: AuthComponent,
children: [
{path: '', redirectTo: '/login', pathMatch: 'full'},
{path: 'login', component: LoginComponent},
{path: 'signin', component: SigninComponent}
]
},
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }
这是我的守卫服务 ->
PS: 我设置默认值 false。
import {Subject, Observable} from 'rxjs';
@Injectable({
providedIn: 'root'
})
export class RouteGuard implements CanActivate {
authorized: Subject<boolean> = new Subject();
canActivate(
route: ActivatedRouteSnapshot,
state: RouterStateSnapshot): boolean {
this.setObservable(false)
return false;
}
getObservable(): Observable<boolean> {
console.log(`starts to observe`)
return this.authorized.asObservable();
}
setObservable(newState: boolean) {
console.log(`new observable state: ${newState}`)
this.authorized.next(newState)
}
}
好的,因为默认值为 returning false,我希望路由自动重定向到 AuthComponent,因为 Auth 是我的路由 [] 中的第二个选项。对吗?
所以...
我在 AuthComponent 声明要观察授权状态:
import {RouteGuard} from '@acn-collections-ws/shared';
@Component({
selector: 'acn-collections-ws-auth',
templateUrl: './auth.component.html',
styleUrls: ['./auth.component.scss']
})
export class AuthComponent implements OnInit {
constructor(private guard: RouteGuard, router: Router) {
console.log('im here');
this.guard.getObservable().subscribe(authorized => {
})
}
ngOnInit(): void {
}
}
但是 AuthComponent 没有加载。似乎当 canActivate 参数 returns 为 false 时,它不会转到 AuthComponent,它不会加载任何东西。当授权(canActivate)return为真时,正常运行。有没有人有类似的问题可以帮助我?
这是我在使用 Firebase 进行身份验证时的做法:
export class GuardGuard implements CanActivate {
constructor(private authService: AuthService, private router: Router){}
async canActivate() {
const user = await this.authService.isLogged();
if(user){
return true;
}
else {
this.router.navigate(['login']);
return false;
}
}
}
如果用户已登录 return true,则加载请求的路由,如果不重定向到登录路由,则 return false。
这是路由:
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { LoginComponent } from './modules/login/pages/login/login.component';
import { SignupComponent } from './modules/login/pages/signup/signup.component';
import { HeroComponent } from './shared/components/hero/hero.component';
import { NotFoundComponent } from './shared/components/not-found/not-found.component';
import { GuardGuard } from './shared/guards/guard.guard';
const routes: Routes = [
{ path: 'home', component: HeroComponent },
{ path: '', redirectTo: 'home', pathMatch: 'full' },
{ path: 'signup', component: SignupComponent },
{ path: 'login', component: LoginComponent },
{ path: 'tasks', loadChildren: ()=> import('./modules/task/task.module').then(m => m.TaskModule), canActivate: [GuardGuard] },
{ path: 'profile', loadChildren: ()=> import('./modules/user/user.module').then(m => m.UserModule), canActivate: [GuardGuard] },
{ path: '**', component: NotFoundComponent }
];
