如何在Ionic 2中嵌入本地HTML页面？

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable()
export class LocalFileService {

  constructor(private http: HttpClient) { }

  getLocalFile(filePath: string) {
    return this.http.get(filePath, { responseType: 'text' });
  }
}

import { Component } from '@angular/core';
import { LocalFileService } from '../../providers/local-file.service';

@Component({
  selector: 'app-local-html',
  templateUrl: 'local-html.page.html',
  styleUrls: ['local-html.page.scss'],
})
export class LocalHtmlPage {

  localHtmlContent: string;

  constructor(private localFileService: LocalFileService) { }

  ionViewDidEnter() {
    const filePath = 'assets/local-html/index.html'; // 替换为你的本地HTML页面路径
    this.localFileService.getLocalFile(filePath).subscribe((data) => {
      this.localHtmlContent = data;
    });
  }
}

<ion-header>
  <ion-toolbar>
    <ion-title>
      Local HTML
    </ion-title>
  </ion-toolbar>
</ion-header>

<ion-content>
  <div [innerHTML]="localHtmlContent"></div>
</ion-content>

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

const routes: Routes = [
  {
    path: 'local-html',
    loadChildren: () => import('./pages/local-html/local-html.module').then(m => m.LocalHtmlPageModule)
  },
  // 其他路由配置...
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }
