引导应用程序angular2 / 4/6时，ngx转换在启动服务中不起作用

Question

我有如下所示的应用程序模块，并且我有一个启动服务，该服务将在应用程序引导之前获取主数据。当我尝试在启动服务中警告翻译后的文本时，它不起作用。但是，如果我花一些时间，它会起作用。如何知道我们需要给多少时间。我猜翻译文件en.json，fr.json文件在我的启动服务调用以获取翻译时未加载。

imports: [
    // :CORE MODULE: //

        loader: {
            provide: TranslateLoader,
            useFactory: (createTranslateLoader),

        }

Appload模块

export function load(appLoadService: AppLoadService) {
  return () => appLoadService.load();
}

@NgModule({
  imports: [HttpClientModule],

    AppLoadService,
    {
      provide: APP_INITIALIZER,
      useFactory: load,
      deps: [AppLoadService],
      multi: true
    }
  ]
})
export class AppLoadModule {}

@Injectable()
export class AppLoadService {

    constructor(
        private httpClient: HttpClient,
        private alertService: AlertService,
        private injector: Injector,
        private $localStorage: LocalStorageService,
    ) { }

    public get router(): Router { //this creates router property on your service.
        return this.injector.get(Router);
    }

    public get translate(): TranslateService { //this creates router property on your service.
        return this.injector.get(TranslateService);
    }

    load(): Promise<any> {
        console.log('1.App Loader: STARTED', new Date().toLocaleTimeString());
        return new Promise(resolve => {
            const promise = this.httpClient.get('assets/settings/config.json')
                .subscribe(
                    res_config => {


                        setTimeout(() => {
                            this.translate.get('logout').subscribe((res: string) => {
                                alert(res); // Not Translating if I give setTimeOut Zero
                            });
                        }, 2000);
