Question

我正在将Angular 4应用程序转换为Angular6。但是，在进行与路由相关的更改时遇到了问题。

现在，当我运行我的应用程序时，将加载Home组件，但不会加载具有空路径的子组件ContentsComponent。

我的应用程序中的路由定义如下：

app.routing.module.ts

const routes: Routes = [
  { path: '', redirectTo: '/home', pathMatch: 'full' },
  { path: 'home', component: HomeComponent },
  { path: 'support', component: SupportComponent }
];

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

export class AppRoutingModule { }

home.routing.module.ts

const routes: Routes = [
  {
    path: 'home', component: HomeComponent, 
    children: [
      { path: '', component: ContentsComponent }, //<-- This component is not loaded
      { path: '**', redirectTo: 'home' }
    ]
  }
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})

export class HomeRoutingModule { }

home.module.ts

@NgModule({
  imports: [
      HomeRoutingModule
      ],
  exports: [],
  declarations: [ HomeComponent, ContentsComponent ],
  providers: [],
})

export class HomeModule { }

app.module.ts

@NgModule({
  imports: [
    BrowserModule,
    AppRoutingModule,
    ReactiveFormsModule,
    HomeModule
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent],
  providers: [
    { provide: LocationStrategy, useClass: HashLocationStrategy }
  ]
})
export class AppModule { }

home.component.html

<router-outlet></router-outlet>

编辑：请注意，我不想在/home网址部分之后显示任何内容。

要在子组件中进行路由，您需要提及其名称。

将“ / home”替换为“ home”。

const routes: Routes = [
  { path: '', redirectTo: 'home', pathMatch: 'full' },
  { path: 'home', component: HomeComponent },
  { path: 'support', component: SupportComponent }
];

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

export class AppRoutingModule { }

在HomeRoutingModule中，您无需再次提及“家”。

仅按以下方式命名子组件。

const routes: Routes = [
  {
    path: '', component: HomeComponent, 
    children: [
      { path: 'content', component: ContentsComponent },
      { path: '**', redirectTo: 'content' }
    ]
  }
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})

export class HomeRoutingModule { }

和如果您不想在路由时更改路由路径，则有两种选择

this.router.navigate(['/home/content'], { skipLocationChange: true });

或

const routes: Routes = [
      {
        path: '', component: HomeComponent, 
        children: [
          { path: '', redirectTo: 'content' }
          { path: 'content', component: ContentsComponent },
          { path: '**', redirectTo: 'content' }
        ]
      }
    ];

如有疑问，请问我。谢谢。

是因为相对路径。尝试以下方法应该可以。

children: [
      { path: '', redirectTo: '/home/content' }, 
      { path: 'content ', component: ContentsComponent }, 
      { path: '**', redirectTo: 'home' }
    ]
