Inject Http in Angular 4.0.0

Question

When I try to call ajax request before bootstrap the app module. I am getting.

  let injector = ReflectiveInjector.resolveAndCreate([
        Http,
        BrowserXhr,
        {provide: RequestOptions, useClass: BaseRequestOptions},
        {provide: ResponseOptions, useClass: BaseResponseOptions},
        {provide: ConnectionBackend, useClass: XHRBackend}
      ]);
      this._http = injector.get(Http);

This should be tagged with angular not in angularjs i think. Also what is the error you are getting. — Bhabani Das, May 04 '17 at 18:02

You need to register the HttpModule to your application. import { HttpModule} from '@angular/http';

@NgModule({
  imports: [
    HttpModule
  ],
  declarations: [AppComponent],
  bootstrap:    [AppComponent]
})
export class AppModule {
}
