Angular 2:模块内的路由(二级嵌套路由器 - 出口)

dkh*_*upt 14 angular2-routing angular

我一直在玩这里找到的Angular 2 webpack启动器,它有很多有用的例子.不过,我遇到了路由问题.我删除了一些模块并添加了我自己的模块,其中包含子项(我仍然不确定使用子模块或子组件是否是最佳实践 - 我目前正在尝试使用组件).

我的目标是能够为正常(顶层模块之间进行切换Home,并About在这种情况下),但加载我经过Home多个子组件之间的模块,交换(或模块,如果是更好的支持)的内部Home模块的模板.

我试图用另一种<router-outlet>Home-我试过将其命名和使用outlet在放慢参数Home模块路由定义,但点击链接内加载Home当前不工作.代码如下:

这是我目前的应用程序结构(大部分额外的webpack东西都被遗漏了):

app
  |-app.component.ts (template contains router-outlet)
  |-app.module.ts
  |-app.routes.ts
  |-about
    |-about.component.ts
    |-about.component.html
  |-home
    |-home.module.ts
    |-home.component.ts
    |-home.component.html (contains router outlet for children)
    |-home.routes.ts
    |-signup
      |-signup.component.ts
      |-signup.component.html
    |-login
      |-login.component.ts
      |-login.component.html

这是我的app.component,它与它在启动器repo中的启动几乎相同 - 我刚刚添加了一个链接到我自己的模块并删除了其他模块:

app.component.ts

import {
 Component,
  OnInit,
  ViewEncapsulation
} from '@angular/core';

@Component({
  selector: 'app',
  encapsulation: ViewEncapsulation.None,
  styleUrls: [
    './app.component.css'
  ],
  template: `

      <a [routerLink]=" ['./home'] " routerLinkActive="active">

      </a>      
      <a [routerLink]=" ['./about'] " routerLinkActive="active">
        About
      </a>
    </nav>
    <main>
      <router-outlet></router-outlet>
    </main>
  `
})
export class AppComponent implements OnInit {

  constructor(
    public appState: AppState
  ) {}

  public ngOnInit() {
    console.log('Initial App State', this.appState.state);
  }

导航到我的Home模块工作正常 - 我认为问题在于它内部的路由.这是Home模块,组件和路由.

import { RouterModule } from '@angular/router';

import { routes } from './home.routes';
import { HomeComponent } from './home.component';
import { SignupComponent } from './signup/signup.component';
import { LoginComponent } from './login/login.component';

console.log('`Home` loaded');

当前的行为是,当我单击其中一个链接时没有任何反应SignupLogin- 没有错误,但组件也没有在aux路由器插座上加载.

我已经尝试配置Signup为模块,但这对我来说还没有用 - 我认为有一些我不理解的额外配置,并认为将子项视为组件将帮助我理解基本的必需路由.

从研究这个问题来看,似乎没有很好的支持多个路由器插座,尤其是使用它们的router-link语法,直到RC5左右.最近对类似问题的回答表明它现在可以正常工作,但类似的语法对我不起作用.

router-outlets嵌套是一个问题吗?我应该将组件SignupLogin组件定义为模块吗?或者是否有一些其他问题与我定义路由的方式一起,也许是在最高的AppModule级别?

编辑

我已经添加app.module.ts了这个问题.另外,在查看我使用的初始项目的基本配置之后,似乎使用子模块可以简化事情 - 特别是barrel模块(此处查看)有一个child-barrel模块,并且它被加载到模板中的router-outlet当前barrel.component.如果有一个child-barrel-2同一级别的模块,这将是我正在寻找的那种东西.

我也找到了这个问题,最佳答案说明了这一点

建议使用模块

我是否应该尝试模仿启动器的结构,通过使用模块完成父子关系?

你为什么使用“.” 尝试将<a [routerLink]=" ['./signup'] ">其删除。.你的基本href是什么

编辑

为什么不在模板中尝试这样的事情呢?

<a [routerLink]="[{outlets: {primary: 'home', aux: 'signup'}}]">signup </a>

以及路由配置中的以下代码

{path: 'signup', component: signUpComponent, outlet:"aux"}
