Angular2延迟加载路线问题 [英] Angular2 lazy loading a route issue

问题描述

Angular2延迟加载路线问题.

Angular2 lazy loading a route issue.

我正在使用Angular2，打字稿，html5和systemjs.

I'm using Angular2, typscript, html5 and systemjs.

我正在尝试让延迟加载适用于我的一条基本路线. 这是我关注的博客，但似乎无法正常运行: http: //blog.angular-university.io/angular2-ngmodule/

I'm trying to get lazy loading working for one of my basic routes. This is the blog I'm following but I can't seem to get it working: http://blog.angular-university.io/angular2-ngmodule/

这是我收到的控制台错误:

未捕获(承诺):错误:无法匹配任何路由.网址段:"500"

Uncaught (in promise): Error: Cannot match any routes. URL Segment: '500'

我的页面是500页. 在下面，我在当前状态下添加了文件.

My page is the 500 page. Below I have added my files at there current state.

用于500页的模块:

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';
import { Component500 } from './500.component';
import { ModuleRouting500 } from './500.routes';

@NgModule({
  imports: [RouterModule, ModuleRouting500],
  declarations: [Component500],
  exports: [Component500],
  providers: []
})
export default class Module500 { }

路由500页:

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';
import { Component500 } from './index';

const Routes500: Routes[] = [
  {
    path: '',
    loadChildren: Component500
  }
];

@NgModule({
  imports: [RouterModule.forChild(Routes500)],
  exports: [RouterModule],
  providers: []
})

export class ModuleRouting500 { }

这是我的核心应用路线页面:(我没有在此处添加路线500)

import { Routes } from '@angular/router';
import { HomeRoutes } from './components/home/index';

export const routes: Routes = [
...HomeRoutes,

{path:'500'，loadChildren:'app/components/500/500.module#Module500'} ];

{ path: '500', loadChildren: 'app/components/500/500.module#Module500' } ];

这是我的核心应用模块页面:(我不在此处添加模块500)

import { NgModule } from '@angular/core';
import { routes } from './app.routes';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { FormsModule} from '@angular/forms';
import { APP_BASE_HREF, CommonModule } from '@angular/common';
import { RouterModule } from '@angular/router';
import { HttpModule } from '@angular/http';
import { AppComponent } from './app.component';

import { HomeModule } from './components/home/home.module';
import { AuthService } from './services/authService/authService';
import { Environment } from './models/environment/environment';

@NgModule({
  imports: [BrowserModule, FormsModule, CommonModule, HttpModule, RouterModule.forRoot(routes), 
  HomeModule
  ],
  declarations: [AppComponent],
  providers: [{
    provide: APP_BASE_HREF,
    useValue: '<%= APP_BASE %>'},
    AuthService,
    Environment
  ],
  bootstrap: [AppComponent]
})

export class AppModule { }

这是500页的index.ts文件:

export * from './500.component';
export * from './500.routes';

推荐答案

您必须通过执行以下操作将懒惰路由添加到App路由中:

You have to add your lazy route in the App route by doing this:

应用路线

export const routes: Routes = [
    ...,
    { path: '500', loadChildren: 'app/components/500/500.module#Module500' },
];

您必须将500.routes.ts更改为以下模块:

You have to change your 500.routes.ts to a module like:

500.routes.ts:

500.routes.ts:

import { NgModule, ModuleWithProviders } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { Component500 } from './index';

const routes: Routes = [
  {
    path: '', 
    component: Component500,
  }
];

@NgModule({
  imports: [RouterModule.forChild(Routes500)],
  exports: [RouterModule],
  providers: []
})

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

然后，在500.module.ts中，您必须加载500.routes.ts

Then, in 500.module.ts you have to load the 500.routes.ts

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';
import { Component500 } from './500.component';
import { routing  } from './500.routes';

@NgModule({
  imports: [RouterModule, routing],
  declarations: [Component500]
})
export class Module500 { }

现在，每个模块都知道路由，无论是否懒惰.

Now, every module knows the routes, being it lazy or not.
