Question

我在app.component.html，admin.component.html和manage-users.component.html中有一个路由器插座。出于某种原因，当我导航到http://localhost:4200/admin/users

时，manage-users.component.html中的路由器出口未输出任何内容

文件的结构如下：

/Admin (Module)
     admin.component.html (has router-outlet)
     admin.component.ts
     admin.module.ts
     admin-routing.module.ts
     /Manage-Users (Module within Admin module)
          manage-users.component.html (has router-outlet)
          manage-users.component.ts
          manage-users.module.ts
          manage-users-routing.module.ts
          /User-List (just a component to be displayed in manage-users outlet)
          ...
          /User-Detail (just a component to be displayed in manage-users outlet)
          ...

我有3种路线：

    // App Routes (app-routing.module.ts)
    const appRoutes: Routes = [
      { path: 'admin', loadChildren: './admin/admin.module#AdminModule', canLoad: [AuthGuard] },
      { path: '',   redirectTo: '/login', pathMatch: 'full' },
      { path: '**', component: PageNotFoundComponent }
    ];

    // Admin Module Routes (admin-routing.module.ts)
    const adminRoutes: Routes = [
      {
        path: '',
        component: AdminComponent,
        children: [
          { path: 'users', component: ManageUsersComponent }
        ]
      }
    ];

    // Admin Module > Manage Users Module Routes (manage-users-routing.module.ts)
const manageUsersRoutes: Routes = [
  {
    path: '',
    component: ManageUsersComponent,
    children: [
      {path: '', component: UserListComponent},
      {path: 'edit/:id', component: UserDetailComponent}
    ]
  }
];

下面是我的ManageUsers.module的样子：

@NgModule({
  declarations: [
    ManageUsersComponent,
    UserListComponent,
    UserDetailComponent
  ],
  imports: [
    CommonModule,
    SharedModule,
    ManageUsersRoutingModule
  ],
  providers: [
    UserService
  ]
})
export class ManageUsersModule { }

下面是我的管理模块的样子：

@NgModule({
  declarations: [
    AdminComponent
  ],
  imports: [
    CommonModule,
    AdminRoutingModule,
    ManageUsersModule
  ]
})
export class AdminModule { }

您需要在用户路由内使用children属性，以便在该路由器出口内加载组件。

设置路由的方式不正确您正在为用户路由使用路由模块，但是您将该模块导入UserModule之外，实际上是将其添加到管理模块内部的现有路由中。

这就是实际情况：

const adminRoutes: Routes = [
  {
    path: '',
    component: AdminComponent,
    children: [
      {
        path: '',
        children:
        [
           { path: 'users', component: ManageUsersComponent }
        ]
      }
    ]
  },
    ...manageTenantRoutes   // your routes are being added here
];

解决此问题的一种方法是像管理模块一样使用延迟加载。

如果要保持这种方式，则必须准确告知这些路由的附加位置。

有关更新，请参见堆栈闪电战

但是您必须像这样添加它：

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { AdminComponent } from './admin.component';
import { ManageUsersComponent } from './manage-users/manage-users.component';

import { manageTenantRoutes } from './manage-users/manage-users-routing.module'
const adminRoutes: Routes = [
  {
    path: '',
    component: AdminComponent,
    children: [
      {
        path: '',
        children:
        [
          ...manageTenantRoutes
        ]
      }
    ]
  }
];

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

并更改您的路线以反映此更改

export const manageTenantRoutes: Routes = [
  {
    path: 'users',
    component: ManageUsersComponent,
    children: [
      {path: '', component: UserListComponent},
      {path: 'edit/:id', component: UserDetailComponent}
    ]
  }
];

希望这可以清除它！

显示组件，但在Angular中忽略了路由器插座
