ng-alain内的core.module.ts里的providers内的参数怎么取值

Question

在core.module.ts内定义 host

import { NgModule, Optional, SkipSelf } from '@angular/core';
import { throwIfAlreadyLoaded } from './module-import-guard';


@NgModule({
  providers: [
    {
      provide: 'host',
      useValue: 'http://localhost/'
    }
  ]
})
export class CoreModule {
  constructor(@Optional() @SkipSelf() parentModule: CoreModule) {
    throwIfAlreadyLoaded(parentModule, 'CoreModule');
  }
}

在routes/passport/login/login.component.ts内如何使用?

Answer 1

login组件所在的module引入CoreMoulelogin, 然后在login组件中注入 host

  constructor(@Inject('host') private host){
  }
