填充子路由器出口Angular2

Question

因为我听说 Angular 的路由器支持嵌套的 标签，所以我尝试使用其中的两个。我正在使用最新的 Angular-CLI，从 ui-router 转换为 Angular 的路由器。我无法获得第二个路由器出口来填充内容。

（父路由工作正常） app-routing.module.ts

...
const routes: Routes = [
    { path: '', pathMatch: 'full', component: LoginComponent },
    { path: 'login', pathMatch: 'full', component: LoginComponent },
    { path: 'dashboard',
        pathMatch: 'full',
        component: DashboardComponent // this holds the second router-outlet
    },
    { path: '**', component: LoginComponent }
];

@NgModule({
    imports: [
        RouterModule.forRoot(routes)
    ],
    exports: [ RouterModule ]
})
export class AppRoutingModule { }

app.component.ts - 这只是包含路由器插座，并且在顶层可以正常工作......

<router-outlet></router-outlet>

仪表板包含通用页眉、页脚、侧边栏等。这就是我希望它在顶级路由器插座中的原因。子路由器出口将填充子视图，但不填充。

尝试 1 dashboard-routing.module.ts

export const dashboardRoutes: Routes = [
    { path: '', pathMatch: 'full', redirectTo: 'home' },
    { path: 'home', pathMatch: 'full', component: HomeComponent },
    { path: 'about', pathMatch: 'full', component: AboutComponent }
]
@NgModule({
    imports: [
        RouterModule.forChild(dashboardRoutes)
    ],
    exports: [ RouterModule ]
})
export class DashboardRoutingModule { }

按照Angular2 : Multiple Router-Outlets & Router-Outlets Inside Child Route尝试2个dashboard-routing.module.ts

export const dashboardRoutes: Routes = [
    {
        path: 'dashboard',
        children:[
            { path: '', component: DashboardComponent},
            { path: 'home', component: HomeComponent},
            { path: 'about', component: AboutComponent}
        ]
    }
 ]
@NgModule({
    imports: [
        RouterModule.forChild(dashboardRoutes)
    ],
    exports: [ RouterModule ]
})
export class DashboardRoutingModule { }

在仪表板模板中，不会填充此嵌套的路由器插座。取而代之的是 app.component.html 中的顶级路由器插座 :(

dashboard.component.html

<header>...</header>
<aside class="sidenav">...<aside>

<!-- why can't I populate you? -->
<router-outlet></router-outlet>

app-routing.module.ts

// seems counter-intuitive that the dashboard component isn't actually in here..., but it works!
const routes: Routes = [
    { path: '', pathMatch: 'full', component: LoginComponent },
    { path: 'login', pathMatch: 'full', component: LoginComponent },
    { path: '**', component: LoginComponent }
];
@NgModule({
    imports: [
        RouterModule.forRoot(routes),
        DashboardRoutingModule // this is the magic. I'm assuming to put it second is better (though putting it first didn't seem to have any immediate negative effect)
    ],
    exports: [ RouterModule ]
})
export class AppRoutingModule { }

dashboard-routing.module.ts

export const dashboardRoutes: Routes = [
    {
        path: 'dashboard',
        component: DashboardComponent,
        children:[
            { path: '', component: HomeComponent },
            { path: 'home', pathMatch: 'full', component: HomeComponent },
            { path: 'about', pathMatch: 'full', component: AboutComponent }
        ]
    }
]
@NgModule({
    imports: [
        RouterModule.forChild(dashboardRoutes)
    ],
    exports: [ RouterModule ]
})
export class DashboardRoutingModule { }

以下是从根目录导航的方法：

login.component.ts

... passed validation ...
this._router.navigate(['/dashboard']);
this._router.navigate(['/dashboard/home']);

或通过仪表板中的侧边栏通过 routerLink 路由 仪表板.component.html

[routerLink]="['../login']" <!-- back to login, though the '../' seems less than ideal

或在仪表板视图中通过 routerLink 到子路由器插座： 仪表板.component.html：

[routerLink]="['../about']"

Answer 1

子router-outlets 在路由器配置中填充children 数组。但是有重复发生。您应该删除 AppRoutingModule 中的 dashboard 条目，然后尝试 2：

应用程序路由

const routes: Routes = [
    { path: '', pathMatch: 'full', component: LoginComponent },
    { path: 'login', pathMatch: 'full', component: LoginComponent },
    { path: '**', component: LoginComponent }
];

在尝试 2 中保持您的 DashboardRoutingModule 原样（使用 children 数组），并在 AppRoutingModule 或 AppModule 中导入此模块。
