Answer 1

截至目前，http模块/组件仍在开发中，尚未发布。在此期间，有两种方法可供使用：

fetch（https://github.com/github/fetch）
axios（https://github.com/mzabriskie/axios）

您可以在此处了解有关新http服务的更多信息：

我认为已经添加了基本支持。基于此example：

使用来自'angular2 / http'//index.ts
在构造函数构造函数中注入Http（http：Http）//http_comp.ts
http.get('./people.json').map(res => res.json()).subscribe(people => this.people = people);

以下是摘录：

import {Component, View} from 'angular2/core';
import {Http, HTTP_BINDINGS} from 'angular2/http';
import {bootstrap} 'angular2/platform/browser';
import {CORE_DIRECTIVES,NgFor} from 'angular/common';

    @Component({
       selector: 'app'
    })

    @View({
        templateUrl: 'devices.html',
        directives: [CORE_DIRECTIVES,NgFor]
    })

    export class App {
        devices: any;
        constructor(http: Http) {
            this.devices = []; 
            http.get('./devices.json').toRx().subscribe(res => this.devices = res.json());
        }
    }

    bootstrap(App,[HTTP_BINDINGS]);
