我得到的EXCEPTION：没有提供商Http！在我的Angular 2.我做错了什么？
import {Http,Headers} from 'angular2/http';
import {Injectable} from 'angular2/core'
@Component({
selector: 'greetings-ac-app2',providers: [],templateUrl: 'app/greetings-ac2.html',directives: [NgFor,NgModel,NgIf,FORM_DIRECTIVES],pipes: []
})
export class GreetingsAcApp2 {
private str:any;
constructor(http: Http) {
this.str = {str:'test'};
http.post('http://localhost:18937/account/registeruiduser/',JSON.stringify(this.str),{
headers: new Headers({
'Content-Type': 'application/json'
})
});
import { HttpModule } from '@angular/http';
@NgModule({
imports: [ BrowserModule,HttpModule],declarations: [ AppComponent ],bootstrap: [ AppComponent ]
})
export default class AppModule { }
platformBrowserDynamic().bootstrapModule(AppModule);
