推荐答案

您可以创建一个共享模块，并将该新共享模块作为导入到需要标头的页面模块:

You can create a shared module and include that new shared module as an import for the page modules that need the header:

shared.module.ts

shared.module.ts

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

import {CommonModule} from '@angular/common';
import {HeaderComponent} from './header/header.component';
import {IonicModule} from '@ionic/angular';

@NgModule({
    imports: [
        CommonModule,
        IonicModule
    ],
    declarations: [HeaderComponent],
    exports: [HeaderComponent]
})
export class SharedModule {}

那么对于 home.module.ts

Then for the home.module.ts

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    IonicModule,
    SharedModule,
    RouterModule.forChild(routes),  
  ],
  declarations: [HomePage]
})
export class HomePageModule {}
