本文介绍了如何在angular2中使用多个路由器插座?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

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

一旦用户进入内容屏幕，我想在顶部显示一个导航栏，有 2 个选项(例如，概览"、见解").此导航栏对于 OverviewComponent 和 InsightsComponent

是通用的

在这个导航栏下方，我想显示另一个路由器插座，它会根据用户在导航栏中的点击加载 OverviewComponent 或 InsightsComponent.如果我将 '/overview' 和/'insights' 作为路由，它会直接向我显示相应的组件，而不是导航栏.

以下是我当前的路由配置(这是不对的):

const appRoutes: Routes = [{ 路径:'main'，组件:MainComponent}，{ 路径:'概览'，组件:概览组件}，{ 路径:'见解'，组件:InsightsComponent }，{ 路径:'登录'，组件:LoginComponent }，{ 小路: ''，重定向到:'/登录'，路径匹配:'完整'},{ 路径:'**'，组件:PageNotFoundComponent }];

请告诉我我们是否可以在 angular2 angular4 中实现这一点.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 - 仍然无法正常工作******************

const appRoutes: Routes = [{ 路径:'主要'，孩子们: [{ 路径:''，组件:MainComponent }，{ 路径:'概览'，组件:概览组件}，{ 路径:'见解'，组件:InsightsComponent }，]},{ 路径:'登录'，组件:LoginComponent }，{ 小路: ''，重定向到:'/登录'，路径匹配:'完整'},{ 路径:'**'，组件:PageNotFoundComponent }];

解决方案

因此，如果我回答对了问题，您希望最初拥有登录屏幕，并且在用户登录后，您希望他看到显示导航的/main.登录屏幕和主应用程序都应该有不同的布局.

我们有一个类似的案例，使用 LayoutComponent.这是一个简化的例子.

//这是具有顶级"路由器的引导的主要组件.@Component({selector: 'app', template: ''})类 AppComponent {}//主路由配置//这里 AuthModule 有配置了登录和注销的路由器和 LoginGuard//当用户未通过身份验证时，将用户重定向到/auth/login.//我们使用延迟加载，但您可以使用直接组件代替出口const APP_ROUTES:路线= [{path: '', redirectTo: 'main', pathMatch: 'full'},{path: 'auth', loadChildren: '../modules/+auth/auth.module#AuthModule'},{小路: ''，组件:布局组件，canActivate: [LoginGuard],孩子们: [{path: 'main', loadChildren: '../modules/+main/main.module#MainModule'}]}];//AuthModule/LoginComponent 有自己的模板，它将被渲染//进入顶级"路由器插座.//布局组件//在这里定义可以包含导航的主应用程序布局//以及应用程序全局的任何其他内容.它有另一个路由器插座//当布局可访问时呈现(在这种情况下，当用户通过身份验证时).@成分({选择器:'应用程序布局'，模板:`<div id="包装器"><app-sidebar></app-sidebar><div id="page-wrapper" class="gray-bg dashboard-1" adjust-content-height><路由器插座></路由器插座>

<通知></通知><error-modal></error-modal>`})导出类 LayoutComponent {}//Auth/LoginComponent 可以有自己的模板，与主应用程序有不同的布局

所以流程是这样的:

希望有所帮助.

更新了 sickelap/ng-starter 存储库，其中包含以下示例应用:

I have a main router-outlet, which is used to display a login screen (/login) and the main content screen(which is shown after login) (/main).

Once the user is on content screen, I want to show a nav-bar on top, with 2 options(say, 'Overview', 'Insights'). This nav-bar is common for OverviewComponent and InsightsComponent

Below this nav-bar, I want to show another router-outlet, which would load OverviewComponent or InsightsComponent, based on what user clicks in nav-bar. If I give '/overview' and /'insights' as the route, it would directly show me the respective component, but not the nav-bar.

Following is my current routing config (this is not right):

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 }
];

Kindly let me know if we can achieve this in angular2 angular4. I'm using following version: 

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

******************Attempt 2 - Still not working******************

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 }

解决方案

So if I get the question right you want to have login screen initially and after the user logs in, you want him to see /main where navigation is shown. Both login screen and main application should have a different layout.

We have a similar case and using LayoutComponent. Here's simplified example.

// 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

So the flow would be like so:

Hope that helps.
