Angular 4 使用命名路由器插座的延迟加载不起作用

Question

我对延迟加载有疑问，不会路由到指定的路由器插座。有人可以看看我哪里错了吗？我有一个主页，其中有一个 link 到 Product -> default router outlet 和 Product Detail -> named router outlet。

  <div>
   <div><a [routerLink]="['product']"> Product </a> </div>
   <div><a [routerLink]="['productdetail',{outlets:{productdetail: 'detail'}}]"> Product Detail </a> </div>
  <div> <router-outlet></router-outlet></div>
  <div> <router-outlet name="detail"></router-outlet>
</div>

下面是插件代码。

这是已知错误，您可以跟踪问题 here

The workaround or we can say solution to this issue is, use non-empty paths for your top level routes if auxilary(i.e. named) routes exist in a lazy loaded module.

我能看到的唯一缺陷是，在路线中添加了一个额外的 url 段

MainRoutingModule：顶级非空路径（即"path: 'load'"）

import { ModuleWithProviders, NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { MainpageComponent } from './mainpage.component';
import { ProductComponent } from './product.component';
import { ProductDetailComponent } from './productdetail.component';

const childroutes: Routes = [

 { path: 'load', component: MainpageComponent  ,
    children: [ 
      {path: 'product', component: ProductComponent
      {path: 'productdetail', component: ProductDetailComponent,
        outlet: 'detail' 
      },

    ]
 },


];

export const routing: ModuleWithProviders = RouterModule.forChild(childroutes);

const newLocal: NgModule = {
    imports: [RouterModule.forChild(childroutes) ],
    exports: [RouterModule, ],
    declarations: []
};

@NgModule(newLocal)


export class MainRoutingModule { }

MainpageComponent:使用辅助路由的正确语法。

[routerLink]="[{outlets:{detail:['productdetail']}}]"

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

@Component({
  selector: 'app-main',
  template: `
  <div>

  <div><a [routerLink]="['product']"> Product </a> </div>
  <div><a [routerLink]="[{outlets:{detail:['productdetail']}}]"> Product Detail </a> </div>
  <div> <router-outlet></router-outlet></div>
  <div> <router-outlet name="detail"></router-outlet>

</div>
  `,
  encapsulation: ViewEncapsulation.None,
})

export class MainpageComponent {}

登录组件：

Use [routerLink]="['mainpage/load']" to load the main module.

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

@Component({
  selector: 'app-login',
  template: `This is login page place holder <br> <a [routerLink]="['mainpage/load']">Go to Main Page</a>`,

})

export class LoginComponent implements Oninit, OnDestroy {
constructor() {}

ngOnInit(): void {}

}

Answer 2

假设路由是 profile ProfileComponent 的一部分（example.com/profile）

profile.component.ts

<a routerLink="/profile/about">About</a>
<a routerLink="/profile/edit">Edit</a>
<a routerLink="/profile/settings">Settings</a>
<router-outlet></router-outlet>

共有三个不同的组件：

关于组件
编辑组件
设置组件

然后路线将如下所示：

{
    path: 'profile',
    component: ProfileComponent,
    children: [
        {
            path: 'about',
            component: AboutComponent
        },
        {
            path: 'edit',
            component: EditComponent
        },
        {
            path: 'settings',
            component: SettingsComponent
        }
    ]
}

解决了 solution 问题，避免空路径“”。感谢 Domenic Helfenstein, who took time to reproduce the problem here 的礼貌。
