用于主（自举）组件的Angular2旋转变压器？

Question

是否可以在angular2？

中的主要组件之前解析服务

Answer 1

在主路径文件中，在最顶层，您可以提到一个解析器名称，该名称将在最顶层组件加载之前解析（这是自举组件）

    {
    path: '',
    resolve: AppComponentResolve,
    children: [
        {
            path: 'somePath',
            component: SomeCOmponent
        }]
    }

将解析器作为注入添加到appComponent文件

    @Injectable()
    export class AppComponentResolve implements Resolve<any> {

    resolve(){
      //return resolved data
     }
    }

Answer 2

在应用默认

下的解析中执行服务

export const appRoutes: Routes = [
  {path:'', pathMatch: 'full', redirectTo: 'home'},
  { 
    path: 'home',
    component: AppComponent,
    resolve: function(){
         //your service call 
    },
  { 
    path: 'path1/:id',
    component: YourComponent,
    resolve: {
      someObject: ComponentResolve
    }
  }
];

@Injectable()
export class ComponentResolve implements Resolve<Interface> {

  constructor(private yourService: YourService) {}

  resolve(route: ActivatedRouteSnapshot) {
    return this.yourService.getMethod(route.params['id']);
  }
