Question

我仍在努力使用角度2.我正在尝试使用http模块，但我得到了未解决的依赖关系。我正在使用alpha 31.这是我的组件的来源：

/// <reference path="../typings/angular2/angular2.d.ts" />

import {Component, View} from 'angular2/angular2';
import {Http, httpInjectables} from 'angular2/angular2';

// Annotation section
@Component({
    selector: 'test',
    appInjector: [httpInjectables]
})
@View({
    templateUrl: 'EcoApp/Views/test.html'
})
// Component controller
export class Test2Component {
    name: string;

    constructor(http: Http) {
        this.name = http.toString();
    }
}

这是我遇到的第一个错误（还有其他错误，未在此处列出）：

No provider for function (_backend, _defaultOptions) {
        this._backend = _backend;
        this._defaultOptions = _defaultOptions;
      }! (Test2Component -> function (_backend, _defaultOptions) {
        this._backend = _backend;
        this._defaultOptions = _defaultOptions;
      })

好的，我必须根据@jhadesdev的回答中的链接回答我自己发现的问题。似乎appInjector已重命名为viewInjector，当我使用后者时它工作得很好。

这里是该问题的链接和揭示帖子
