返回到上一页，然后以角度输入嵌套的URL

Question

我的路线如下：

    const routes: Routes = [
  {path: '', redirectTo: 'home', pathMatch: 'full'},
  {path: 'find', redirectTo: 'search'},
  {path: 'home', component: HomeComponent},
  {path: 'search', component: SearchComponent},
  {
    path: 'artist/:artistId',
    component: ArtistComponent,
    children: [
      {path: '', redirectTo: 'tracks'}, 
      {path: 'tracks', component: ArtistTrackListComponent}, 
      {path: 'albums', component: ArtistAlbumListComponent}, 
    ]
  },
  {path: '**', component: HomeComponent}
];

可以从任何页面导航到子页面并在它们之间切换。有一个按钮可以将我们带回到子页面的导航页面。

例如： 如果某人从主页导航至“ artist /：artistId /曲目”，然后导航至“ artist /：artistId /相册”。如果该人单击“后退”按钮，则用户应导航至主页。
