带参数的Angular4嵌套路由

const routes: Routes = [
  { path: 'parent', component: ParentComponent, children: [
    { path: 'child/:id', component: ChildComponent }
  ]}
];

<router-outlet></router-outlet>

import { ActivatedRoute } from '@angular/router';

constructor(private route: ActivatedRoute) {}

ngOnInit() {
  this.route.params.subscribe(params => {
    const id = params['id'];
    // 使用参数进行相应的操作
  });
}

<a [routerLink]="['/parent/child', 1]">Child 1</a>
<a [routerLink]="['/parent/child', 2]">Child 2</a>
