【问题描述】:
在尝试了所有其他解决方案后,我仍然遇到问题:尝试导航到其他组件, URL 已更改,但我停留在同一页面上,目标组件未加载。
解释:
当用户到达App时,基于会话存储,他转到HOME组件或LOGIN组件。
如果他登陆 HOME 组件,EVERYTHING's work,他可以在应用程序的任何地方导航。

我使用了延迟加载和 authGuard。
控制台没有错误。
上述两种情况之间的路由器跟踪日志是相同的(我的意思是在第二种情况下,NavigationEnd 组件是正确的目标组件,但它从未加载过)
这是我的app-routing.module.ts:
const routes: Routes = [
{
path: '',
redirectTo: 'login',
pathMatch: 'full',
},
{
path: 'home',
loadChildren: './pages/home/home.module#HomeModule',
canActivate: [AuthGuard]
},
{
path: 'description',
loadChildren: './pages/description/description.module#DescriptionModule',
canActivate: [AuthGuard]
},
{
path: 'nsp',
loadChildren: './pages/nsp/nsp.module#NspModule',
canActivate: [AuthGuard]
},
{
path: 'login',
loadChildren: './pages/login/login.module#LoginModule'
},
{
path: 'mappings',
loadChildren: './pages/mappings/mappings.module#MappingsModule',
canActivate: [AuthGuard]
},
{
path: 'performances',
loadChildren: './pages/performances/performances.module#PerformancesModule',
canActivate: [AuthGuard]
}
];
@NgModule({
imports: [RouterModule.forRoot(routes, {enableTracing: true })],
exports: [RouterModule]
})
export class AppRoutingModule { }
这是我的auth-guard.service.ts:
export class AuthGuardService implements CanActivate {
constructor(private storageFactory: StorageFactoryService,
public auth: AuthentificationService,
public router: Router) {}
session_date_expire_on: string;
canActivate(_route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
if (this.storageFactory.get('ssid_expires_on') != null) {
var date_stored =
new Date(this.storageFactory.get('ssid_expires_on').value);
}
var current_date = new Date();
if (typeof this.storageFactory.get('userid') !== 'undefined' &&
this.storageFactory.get('userid') !== null &&
date_stored > current_date) {
this.storageFactory.remove('ssid_expires_on');
this.session_date_expire_on = new Date(current_date.getTime() +
environment.inactivity_timeout).toString();
this.storageFactory.set('ssid_expires_on', this.session_date_expire_on);
current_date = null;
return true;
}
localStorage.clear();
sessionStorage.clear();
this.router.navigate(['/login']);
return false;
}
}
我的app.component.ts 直接重定向到 HOME 组件,因此调用 authGuard 并在需要时重定向到 LOGIN:
export class AppComponent implements OnInit {
constructor(private checkSessionService: CheckSessionService,
private storageFactory: StorageFactoryService,
private ElementRef: ElementRef,
private api_user: AuthentificationService,
private router: Router) { }
ngOnInit() {
console.log("--------- App Component ---------");
this.router.navigate(['/home']);
}
}
问题是当我转到login.component.ts 并单击日志功能时,如果用户经过身份验证,它会转到主页然后没有导航工作:
export class LoginComponent implements OnInit {
user: UserInfo;
current_date = new Date();
session_date_expire_on: string;
access_granted: boolean;
constructor(private ngZone: NgZone,
private storageFactory: StorageFactoryService,
private api_user: AuthentificationService,
private router: Router,
private route: ActivatedRoute) { }
ngOnInit() {}
log() {
return this.api_user.getUser().subscribe(response => {
if (response.status == 200) {
this.user = response.body;
this.session_date_expire_on = new Date(this.current_date.getTime() +
environment.inactivity_timeout).toString();
this.storageFactory.set('userid', this.user.userId);
this.storageFactory.set('usercountry', this.user.entityCountryName);
this.storageFactory.set('userrights', this.user.profile[0]);
this.storageFactory.set('ssid', uuid());
this.storageFactory.set('ssid_expires_on', this.session_date_expire_on);
this.router.navigate(['/home']);
} else {
this.router.navigate(['/login']);
}
})
}
}
你有什么想法吗?
我已经尝试过.. --> this.router.navigate([../home])
【问题讨论】:
-
为什么在日志函数中返回响应
-
@HitechHitesh 我的错,你说得对,我删除了它。
-
以前没有人遇到过这个问题?
