“错误：未捕获（承诺）：没有Jsonp提供程序”（HTML / Javascript / Typescript / Angular2）

错误的屏幕截图：

.ts文件代码（SearchDisplay.component.ts）：

import {Component, OnInit} from 'angular2/core';
import {Router} from 'angular2/router';
import {Hero} from './hero';
import {HeroService} from './hero.service';
import {RouteConfig, ROUTER_DIRECTIVES} from 'angular2/router';
import {HeroesComponent} from './heroes.component';
import {HeroDetailComponent} from './hero-detail.component';
import {DashboardComponent} from './dashboard.component';
import {SpreadSheetComponent} from './spreadsheeteditall.component';
import {SwitchUsersComponent} from './SwitchUsers.component';
import {BiddingPageComponent} from './BiddingPage.component';
import { Injectable } from 'angular2/core';
import { Jsonp, URLSearchParams } from 'angular2/http';



@Component({
  selector: 'SearchAndDisplayComponent',
  templateUrl: 'app/SearchDisplay.component.html',
  styleUrls: ['app/SearchDisplay.component.css'],
  providers: [HeroService],
  directives: [ROUTER_DIRECTIVES]
})

@Injectable()

export class SearchAndDisplayComponent{
   constructor(private jsonp: Jsonp) {}
  search (term: string) {
    let ebayURL = 'http://developer.ebay.com/Devzone/XML/docs/reference/ebay/index.html';
    var params = new URLSearchParams();
params.set('search', term); // the user's search value
    params.set('action', 'opensearch');
    params.set('format', 'json');
    params.set('callback', 'JSONP_CALLBACK');
    // TODO: Add error handling
    return this.jsonp
               .get( ebayURL, { search: params })
               .map(request => <string[]> request.json()[1]);
  }


}

我认为可能是导致该错误（.SearchDisplay.component.html）的.html文件代码的一部分：

<input class="search2" id="txtSearch" type="text" name="serach_bar" size="31" maxlength="255"       
value="" style="left: 396px; top: 153px; width: 293px; height: 26px;" />
<input class="search1" type="submit" name="submition" value="Search" style=" padding-  
bottom:20px; left: 691px; top: 153px; height: 23px" />
<button (click)="search(term)">Search</button>
<script type="text/javascript">
    document.getElementById('frmSearch').onsubmit = function() {
        window.location = 'local data here (not sure how to code this)' + document.getElementById('txtSearch').value;
        return false;
    }
</script>

问题背景：我正在尝试为基本上是eBay克隆的网站创建搜索栏。

原始代码来自Wikipedia示例搜索栏，但我想将其更改为从ebay提取数据（或仅创建一个本地搜索栏，仅包含单词“ apple”和“ car”）。

在这个问题中发布了指向punker /全压缩项目文件的链接：
