Angular在实现延迟加载后取消从APP_INITIALIZER发送HttpRequest

import { APP_INITIALIZER, NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ApplicationInitStatus } from '@angular/core';

// 延迟加载模块
import { LazyModule } from './lazy.module';

// 初始化操作函数
export function initializeApp(appInitStatus: ApplicationInitStatus) {
  return () => {
    // 执行一些初始化操作，例如发送HttpRequest获取必要的数据
    // ...

    // 初始化完成，通知Angular
    appInitStatus.done();
  };
}

@NgModule({
  imports: [BrowserModule, LazyModule],
  providers: [
    {
      provide: APP_INITIALIZER,
      useFactory: initializeApp,
      deps: [ApplicationInitStatus],
      multi: true,
    },
  ],
})
export class AppModule {}
