Http.post错误:map不是Angular 2中的函数

我正试图通过http.post函数从url获取数据.但是我收到了错误.app.component.ts文件的源代码:

import {Component} from 'angular2/core';
import {bootstrap} from 'angular2/platform/browser';
import {Http, HTTP_PROVIDERS, Headers} from 'angular2/http';
@Component({
selector: 'my-app',
template: `
 

  Post Data
  
Posted the following values:
  
{{postResponse.id}}
  
{{postResponse.name}}
 
`
})
export class AppComponent {
 result: Object;
 http: Http;
 postResponse = new Person();

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

 postData(){
    var headers = new Headers();
    headers.append('Content-Type', 'application/json');

    this.http.post('http://141.79.39.454:8008/the-link-something-like-this...', JSON.stringify({"id": 1, "name": "?????"}),{headers:headers})
    .map(res => res.json())
    .subscribe((res:Person) => this.postResponse = res);
 }
}

class Person{
 id:number;
 name:string;
}

bootstrap(AppComponent, [HTTP_PROVIDERS]);

url中的JSON看起来像这样. 当我点击按钮时我得到的错误如下:

EXCEPTION: Error during evaluation of "click"

也许您可以尝试在导入中添加以下内容:

import 'rxjs/add/operator/map';
