如何在angular2中使用多个路由器插座？

Question

我有一个main router-outlet,用于显示登录屏幕(/login)和主要内容屏幕(登录后显示)(/main).

一旦用户在内容屏幕上,我想在顶部显示导航栏,有2个选项(例如,"概述","洞察").这个导航栏是OverviewComponent和InsightsComponent

在这个导航栏下面,我想显示另一个路由器插座,它将加载OverviewComponent或InsightsComponent根据用户在导航栏中点击的内容.如果我将'/ overview'和/'insights'作为路线,它将直接显示相应的组件,但不会显示导航栏.

以下是我当前的路由配置(这不对):

const appRoutes: Routes = [
  { path: 'main', component:  MainComponent},
  { path: 'overview', component:  OverviewComponent},
  { path: 'insights', component: InsightsComponent },
  { path: 'login', component: LoginComponent },
  { path: '',
    redirectTo: '/login',
    pathMatch: 'full'
  },
  { path: '**', component: PageNotFoundComponent }
];

如果我们能够在angular2 angular4中实现这一点,请告诉我.我正在使用以下版本:

"@angular/core": "^4.0.0"
"@angular/router": "^4.0.0"
"@angular/cli": "1.0.1"

******************尝试2 - 仍然没有工作******************

const appRoutes: Routes = [
  { path: 'main',
    children: [
      { path: '', component: MainComponent },
      { path: 'overview', component:  OverviewComponent },
      { path: 'insights', component: InsightsComponent },
    ]

  },
  { path: 'login', component: LoginComponent },
  { path: '',
    redirectTo: '/login',
    pathMatch: 'full'
  },
  { path: '**', component: PageNotFoundComponent }
];

*******尝试2 - 包含所有组件的Sudo代码 - 仍然无法正常工作*******

//app.component.html

<router-outlet></router-outlet>


//app.module.ts

const appRoutes: Routes = [
  { path: 'main',
    children: [
      { path: '', component: MainComponent },
      { path: 'overview', component:  OverviewComponent },
      { path: 'insights', component: InsightsComponent },
    ]

  },
  { path: 'login', component: LoginComponent },
  { path: '',
    redirectTo: '/login',
    pathMatch: 'full'
  },
  { path: '**', component: PageNotFoundComponent }
];

//login.component.html
<div class="text-center vertical-center">
    <form>
        <div class="horizontal">
            <label for="">Email</label>
            <input class="form-control" type="text" name="" value="">
        </div>
        <div class="horizontal">
            <label for="">Password</label>
            <input class="form-control" type="password" name="" value="">
        </div>
        <button class="btn btn-primary" (click)="navigate()">Login</button>
    </form>
</div>

//login.component.ts
navigate() {
    this.router.navigate(['./main']);
  }

//main.component.html

<app-header></app-header>
<router-outlet></router-outlet>


//app.header.html

<ul class="nav navbar-nav">
               <li class=""><a routerLink="/main/overview" routerLinkActive="active">OVERVIEW</a></li>
                <li class=""><a routerLink="/main/insights" routerLinkActive="active">INSIGHTS</a></li>
            </ul>

//overview.html
<p>This is overview section</p>

//insights.html
<p>This is insights section</p>

********尝试3 - 工作**********

const appRoutes: Routes = [

      { path: '', component: MainComponent },

因此,如果我得到正确的问题,您希望最初有登录屏幕,并且在用户登录后,您希望他看到/主要显示导航的位置.登录屏幕和主应用程序都应具有不同的布局.

我们有类似的情况并使用LayoutComponent.这是简化的例子.

// This is main component that get's bootstrapped that has 'top-level' router.
@Component({selector: 'app', template: '<router-outlet></router-outlet>'})
class AppComponent {}

// main router config
// Here AuthModule has router with login and logout configured and LoginGuard
// redirect the user to /auth/login when she is not authenticated.
// We're using lazy-loading but you can use direct component instead
export const APP_ROUTES: Routes = [
  {path: '', redirectTo: 'main', pathMatch: 'full'},
  {path: 'auth', loadChildren: '../modules/+auth/auth.module#AuthModule'},
  {
    path: '',
    component: LayoutComponent,
    canActivate: [LoginGuard],
    children: [
      {path: 'main', loadChildren: '../modules/+main/main.module#MainModule'}
    ]
  }
];

// AuthModule/LoginComponent has own template and it will be rendered
// into 'top-level' router-outlet.

// LayoutComponent
// Here you define your main application layout that can include navigation
// and anything else that are global to the app. It has another router-outlet
// that get rendered when the layout is accessible (which in this case when the user is authenticated).
@Component({
  selector: 'app-layout',
  template: `
    <div id="wrapper">
      <app-sidebar></app-sidebar>
      <div id="page-wrapper" class="gray-bg dashboard-1" adjust-content-height>
        <router-outlet></router-outlet>
      </div>
    </div>
    <notifications></notifications>
    <error-modal></error-modal>
  `
})
export class LayoutComponent {}

// Auth/LoginComponent can have its own template that will have different layout from the main application

所以流程是这样的:

• 当用户尝试加载/然后她重定向到/ main
• 如果用户未经过身份验证,则重定向到/ auth/login,然后加载/ main

希望有所帮助.

编辑:使用示例应用更新了sickelap/ng-starter存储库,其中包含:

• 使用延迟加载进行路由
• 布局
• 和其他东西
