如何為延遲加載angular 2 NgModule中的loadchildren提供正確的路徑名？

Question

如何在angular 2 ngmodule的app-routing.module文件中為loadchildren提供正確的路徑名，我遵循了angular主要網站中的ngmodule概念，但未提供此類信息。 我遇到了app-routing.module路徑的問題，我需要在路徑名中指定該問題，此問題導致延遲加載不起作用。所有文件一次都加載一次，有人可以幫忙嗎？ 我在loadchildrens的路徑中想念什么？ 關注了這個Angular NgModule

app-routing.module文件。

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import {DashboardModule} from './dashboard/dashboard.module';
import {VideosModule} from './videos/videos.module';


export const routes: Routes = [
    { path: 'login', component: LoginComponent },
    { path: '', redirectTo: 'home/dashboard', pathMatch: 'full', canActivate: [AuthGuard] },
    {
        path: 'home', component: HomeComponent, canActivate: [AuthGuard],
        children: [
            { path: '', loadChildren: 'app/dashboard/dashboard.module#DashboardModule' },
            { path: 'videos', loadChildren: 'app/videos/videos.module#VideosModule' },

            ]
    },
];

app.module文件

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {FormsModule, FormGroup, ReactiveFormsModule} from '@angular/forms';
import { CommonModule} from '@angular/common';

import {AppRoutingModule } from './app-routing.module';
import { AppComponent }   from './app.component';
import { AuthGuard } from './auth.guard';
import { AuthenticationService } from './shared/services/authentication.service';
import {LoginComponent} from './login/login.component';

import {SharedModule} from './shared/share.module';

import {DashboardModule} from './dashboard/dashboard.module';
import {VideosModule} from './videos/videos.module';

@NgModule({
    imports: [
        BrowserModule, FormsModule, AppRoutingModule, DashboardModule,
        SharedModule, VideosModule, 
        ReactiveFormsModule, CommonModule
    ],
    declarations: [AppComponent, LoginComponent
    ],
    exports: [],
    providers: [
        AuthGuard,
        AuthenticationService,
          ],
    bootstrap: [AppComponent]
})

export class AppModule { }

videos-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import {FileUploadComponent} from './upload_videos/uploadvideo.component';
import {ManageVideosComponent} from './manage_videos/managevideos.component';


 export const routes: Routes = [
      { path: ' ', redirectTo:'fileupload',pathMatch:'full'},
      { path: 'fileupload', component: FileUploadComponent },                         
      { path: 'manage_videos', component: ManageVideosComponent },
  ];
@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class VideosRoutingModule {}

videos.module文件

import { NgModule }           from '@angular/core';
import { CommonModule }       from '@angular/common';

import {FormsModule, ReactiveFormsModule} from '@angular/forms';
import {SharedModule} from '../shared/share.module';
import {VideoFileService} from './services/videofile.service';

import { FileSelectDirective, FileDropDirective } from 'ng2-file-upload';
import {FileUploadModule} from 'ng2-file-upload/ng2-file-upload';
import {ManageVideosComponent} from './manage_videos/managevideos.component';

import {VideosRoutingModule} from './videos-routing.module';


@NgModule({
  imports:      [ VideosRoutingModule,SharedModule,CommonModule,
                  FormsModule,ReactiveFormsModule ,FileUploadModule],
  declarations: [ManageVideosComponent,
                 FileUploadComponent],
  exports:      [ FileSelectDirective,FileDropDirective ],
  providers:    [ VideoFileService ]
})
export class VideosModule { }

我找到了正確的解決方案。

我們需要從app.module.ts文件中刪除視頻模塊導入模塊，但儀表板模塊除外，因為它首先加載，並且我們已經使用loadChildren概念將視頻模塊導入了app.routing.ts文件中，因此無需在以下位置導入視頻模塊app.module.ts，因為它的延遲加載，現在可以正常工作的延遲加載，以及路徑名，無論您想要什么，都可以給出，並使用路由器鏈接來調用該路徑。僅在鏈接https：//devblog.dymel之后.pl / 2016/10/06 / lazy-loading-angular2-modules /謝謝
