如何使用JavaScript(ES6)在AngularJS 2中执行HTTP GET请求?该文档仅显示TypeScript。

你可以使用类似的东西:

import {Http, URLSearchParams} from 'angular2/http';

@Injectable()
export class SomeHttpService {
  constructor(http) {
    this.http = http;
  }

  getSomething() {
    URLSearchParams params = new URLSearchParams();
    params.set('id', '1');
    return this.http.get('http://...', { search: params }).map(res => res.map());

    /*
      or if you need to subscribe in the service

      this.http.get('http://...').map(res => res.map())
               .subscribe(
                 (data) => {
                   // do something with data
                 }
               );
    */
  }

  static get parameters() {
    return [[Http]];
  }
}

不要忘记导入Angular2 Http模块文件:

<script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>
<script src="node_modules/rxjs/bundles/Rx.js"></script>
<script src="node_modules/angular2/bundles/angular2.dev.js"></script>
<script src="node_modules/angular2/bundles/http.dev.js"></script> <---

并在引导您的应用程序时设置HTTP_PROVIDERS提供程序:

import {HTTP_PROVIDERS} from 'angular2/http';
(...)

bootstrap(AppComponent, [ HTTP_PROVIDERS ]);

事实上,ES6唯一特有的是使用静态getter配置依赖注入的方法......
