Question

我正在尝试创建子菜单，这些子菜单是我主要路径的子项，并通过辅助命名出口输出。但是，每当我尝试让应用程序路由到子路由时，我都会收到错误Error: Cannot match any routes. URL Segment: 'apps/subroute'。

apps.component.html

<nav>
  <ul>
    <!-- Create navigation -->
    <li *ngFor="let routing of subRouteList"
    routerLinkActive="active"
    (click)="subRoute(routing.name)">
      <a>
        {{routing.name}}
      </a>
    </li>
  </ul>
</nav>

<h2>Applications by <em>Peter David Carter</em></h2>
<router-outlet name="appCategories"></router-outlet>

  This is the section of the page where I'll be putting
  some applications I've been working on.
  Should be a few here within the next couple of days,
  but for now I've including a link to a basic Skype
  bot I created for an old project. If you're interested
  in talking to <a href="https://join.skype.com/bot/1622b401-3752-465b-99d4-72aab7df6842">Emile</a>
  click his name to add him as your Skype contact...

  subRoute(route: string): void {
    console.log('entered subroute');
    this.router.navigate([route], { relativeTo: this.route });
  }

  ngOnInit() {

  }

}

app.routing-module.ts

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

import { AboutComponent } from '../about/about.component';
import { BlogComponent } from '../blog/blog.component';
import { AppsComponent } from '../apps/apps.component';
import { ApiComponent } from '../api/api.component';
import { ProfileComponent } from '../users/profile.component';

import { AnimationsComponent } from '../apps/animations/animations.component';
import { BotsComponent } from '../apps/bots/bots.component';
import { VisualisationsComponent } from '../apps/visualisations/visualisations.component';
import { MiscComponent } from '../apps/misc/misc.component';

const routings: Routes = [
  { path: '', redirectTo: '/about', pathMatch: 'full' },
  { path: 'about',      component: AboutComponent },
  { path: 'blog',       component: BlogComponent },
  { path: 'apps',
    component: AppsComponent,
    children: [
      {
        path: 'animations',
        component: AnimationsComponent,
        outlet: 'appCategories'
      },
      {
        path: 'bots',
        component: BotsComponent,
        outlet: 'appCategories'
      },
      {
        path: 'visualisations',
        component: VisualisationsComponent,
        outlet: 'appCategories'
      },
      {
        path: 'misc',
        component: MiscComponent,
        outlet: 'appCategories'
      },
    ]},
  { path: 'api',        component: ApiComponent },
  { path: 'profile',    component: ProfileComponent }
];

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

由于这些路线已被定义为apps路线的子项，因此我认为apps/subroute路由现在应该有效。我是否需要做一些不同或额外的事情来使事情正常工作？

我找到了让它发挥作用的方法。我现在有：

<nav>
  <ul>
    <!-- Create navigation -->
    <li *ngFor="let routing of subRouteList"
    routerLinkActive="active"
    [routerLink]="[{ outlets: { appCategories: routing.name } }]">
      <a>
        {{routing.name}}
      </a>
    </li>
  </ul>
</nav>

在视图中

，我没有使用控制器中的路由代码。

router.navigate代码似乎以这种形式生成路由：apps/animations但是通过命名出口输出的子路由的正确格式为/apps/(appCategories:animations)。
