如何路由到功能模块

Question

我试图让来自一个模块的路由包含来自另一个模块的组件。我正在尝试实施的方案是：/group/feature，它应该显示 feature.html 中的内容，该内容包含在路由器插座所在的 group.html 的内容中。我可以让/group 工作，但/group/feature 返回page not found。

完整的项目在这里：https://stackblitz.com/edit/angular-nsfgyr

这里是主要文件：

feature.module.ts：

@NgModule({
  imports: [
    CommonModule
  ],
  declarations: [FeatureComponent],
  exports: [FeatureComponent]
})
export class FeatureModule {
}

group-module.ts

@NgModule({
  imports: [
    CommonModule,
    FeatureModule,
    GroupRoutingModule,
  ],
  declarations: [
    GroupComponent,
  ],
  exports: [GroupComponent]
})
export class GroupModule {
}

group-routing.module.ts:

const ingestRoutes: Routes = [
  {path: 'feature', component: FeatureComponent}
];

@NgModule({
  imports: [
    RouterModule.forChild(ingestRoutes)
  ],
  exports: [
    RouterModule
  ]
})
export class GroupRoutingModule {
}

app-routing.module:

const routes: Routes = [
    {path: '', pathMatch: 'full', redirectTo: 'group'},
    {path: 'group', component: GroupComponent},
    {path: '**', component: PageNotFoundComponent}
  ]
;

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

Answer 1

您已经为'group' 定义了路由。你还没有定义路由'group/feature'。

更新：

你的 group 路由看起来像一个普通的 /group 路由，但 group 实际上是一个子模块，你不加载组件，你 loadChildren。

const routes: Routes = [
    {path: '', pathMatch: 'full', redirectTo: 'group'},
    {path: 'group', loadChildren: 'app/group/group.module#GroupModule},
    {path: '**', component: PageNotFoundComponent}
  ]
;

第一种方式。没有孩子，没有导入模块。

const routes: Routes = [
  {path: '', pathMatch: 'full', redirectTo: 'group'},
  {path: 'group/feature', component: FeatureComponent },
  {path: 'group', component: GroupComponent},
  {path: '**', component: PageNotFoundComponent}
];

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

第二种方式是使用children..

const routes: Routes = [
  {path: '', pathMatch: 'full', redirectTo: 'group'},
  {path: 'group', component: GroupComponent,
   children: [
    { path: 'feature', component: FeatureComponent }]     
  },
  {path: '**', component: PageNotFoundComponent}
];

第三种方式是导入模块。它有自己的

"<router-outlet></router-outlet>".

const ingestRoutes: Routes = [
  { path: 'group/feature', component: FeatureComponent,
    children: [       
      path: 'more', component: MoreComponent, // if you want to add..
        // this will route to group/feature/more
      path: '', component: FeatureHomeComponent,
    ] 
  }
];

@NgModule({
  imports: [
    RouterModule.forChild(ingestRoutes)
  ],
  declarations: [
      FeatureComponent, FeatureHomeComponent, MoreComponent
  ],
  exports: [
    RouterModule
  ]
})
export class GroupRoutingModule {
}

FeatureComponent.html 只有

<route-outlet></router-outlet>. 

FeatureHomeComponent.html

- you can display anything here..YOUR ACTURE FEATURE COMPONENT.HTML

在 AppRoutingModule 中导出。

 const routes: Routes = [
    {path: '', pathMatch: 'full', redirectTo: 'group'},
    {path: 'group', component: GroupComponent},
    {path: '**', component: PageNotFoundComponent}
  ];

@NgModule({
  imports: [
    RouterModule.forRoot(routes, {enableTracing: false, useHash: 
    false}), GroupRoutingModule, // add this..
  ],
  exports: [
    RouterModule
  ]
})
export class AppRoutingModule {
}

我为“苹果品牌”所做的只是在我的 AppRoutingModule 中导入 AppleRoutingModule。见链接。Angular 4 route selection for category/subcategory or category/item for ecommerce web site

我想通了：在组路由器的子数组中添加特征路径有效：

在 group-routing.module.ts 中：

const ingestRoutes: Routes = [
  {path: 'group', component: GroupComponent,
   children: [
     {path: 'feature', component: FeatureComponent}
  ]},
];
