Angular 延迟加载模块 - child 路由中的问题

Question

我有一些模块："dashboard"、"family" 和 "children"。这些模块在我的 appRoute 中延迟加载，除了 "childen" 模块：

export const appRoutes: Routes = [
  { path: '', loadChildren: 'app/dashboard/dashboard.module#DashboardModule' },
  { path: 'family', loadChildren: 'app/family/family.module#FamilyModule' },
  {
    path: '404',
    component: Error404PageComponent,
    resolve: { data: Error404PageResolver }
  },
  {
    path: '**',
    component: Error404PageComponent,
    resolve: { data: Error404PageResolver }
  }
];


@NgModule({
  imports: [ RouterModule.forRoot(appRoutes, {
    preloadingStrategy: PreloadAllModules,
    useHash: false
  }) ],
  exports: [ RouterModule ]
})
export class AppRoutingModule {}

我家的路线文件是这样的：

const familyRoutes: Routes = [
    {
        path: '',
        component: FamilyComponent
    {
        path: ':id',
        component: FamilleComponent     
];

@NgModule({
    imports: [RouterModule.forChild(familyRoutes)],
    exports: [RouterModule]
})
export class FamilyRoutingModule { }

对于我的 "children" 模块，它几乎是一样的，除了路由，路由的第一部分包含家庭路由：

const childRoutes: Routes = [
  {
    path: 'family/:familyId/child',
    component: ChildComponent
  },
  {
    path: 'family/:familyId/child/:id',
    component: ChildComponent
  }
];

我想延迟加载 "children" 模块，但我不知道该怎么做，因为该模块是模块 "family" 的 child。我的问题是链接到 child 的路线不可用。所以 url http://localhost:4200/family/830503261/child/830581020 无效。

我尝试在 familyRoutes 中添加 loadChildren 行，但不起作用：

const familleRoutes: Routes = [
    {
        path: '',
        component: FamilyComponent
    {
        path: ':id',
        component: FamilyComponent,     
        loadChildren: './../child/child.module#ChildModule' 
];

我不知道如何使用路由中的路径 "family" 访问我的 children。

有什么想法吗？谢谢。

Answer 1

您应该将您的 childModule 配置为 children 的 family route

    const familyRoutes: Routes = [
        {
            path: '',
            component: FamilyComponent
        },
        {
            path: ':id',
            component: FamilleComponent,
            children: [
                'path': 'child',
                'loadChildren': './../child/child.module#ChildModule', // <- or whatever path

            ]
        }

    ];

    @NgModule({
        imports: [RouterModule.forChild(familyRoutes)],
        exports: [RouterModule]
    })
    export class FamilyRoutingModule { }

并更改您的子模块的路由

const childRoutes: Routes = [
  {
    path: '',
    component: ChildComponent
  },
  {
    path: ':id',
    component: ChildComponent
  }
];

Answer 2

感谢您的回复。这是工作。我只是添加 {}:

children: [
            {
                path: 'child',
                loadChildren: './../child/child.module#ChildModule'
            }
        ],

我还有一个问题。在我的子路由文件中，我还有一个守卫和其他东西：

const childRoutes: Routes = [
  {
    path: '',
    component: ChildComponent,
    resolve: { user: AuthResolver, referentiel: ReferentielChildResolver },
    canActivate: [ChildActivateGuard]

  },
  {
    path: ':id',
    component: ChildComponent,
    resolve: { user: AuthResolver, child: ChildResolver, referentiel: ReferentielChildResolver },
    canActivate: [ChildActivateGuard]
  }
];

在我的 ChildActivateGuard 中，我想拥有我家人的 ID：

Injectable()
export class EleveActivateGuard implements CanActivate {

  can: boolean;
  constructor(private childService: ChildService, public http: HttpService) 
  { }

canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> | boolean {

    debugger;
    console.log(route.parent.params["familyId"]);
    ....
   }

但是参数 familyId 未定义。我不明白缺少什么？谢谢您的帮助。

Answer 3

谢谢皮埃尔的评论。

我找到了解决办法。即使我不确定这是最好的解决方案，但它在我的子组件的保护文件中工作：

 canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> | boolean {

    var familyIdId = route.parent.parent.url[0].path;
    ...
