我使用typescript构建一个角度2应用程序,我尝试创建新的组件调用sidekik.component.ts并导入到这样的app.component.ts.

app.component.ts

import {Component} from 'angular2/core';
import {SideKikComponent} from './classes/sidekik.component';

interface Hero {
   id: number;
   name: string;
}

@Component({
  selector: 'my-app',
  directives:[
    SideKikComponent,
  ],
  templateUrl:'app/views/heros.html',
  styleUrls: ['app/css/site.css']
})

export class AppComponent { 
  public title = 'Tour of Heroes';
  public heroes =HEROS;
  public selectedHero: Hero;

  onSelect(hero: Hero) { 
    this.selectedHero = hero; 
  }
}

var HEROS: Hero[] =[
  {"id":1,"name":"SuperMan"},
  {"id":2,"name":"Captain America"},
  {"id":3,"name":"Thor"},
  {"id":4,"name":"Iorn Man"},
  {"id":5,"name":"Ant Man"}
];

sidekik.component.ts

import {Component, View} from 'angular2/core';

@Component({
  selector:'sidekik',
  events:['hit'],
  properties:['define'],
  template: `
    <sidekik (click) = …

我使用角度cli创建应用程序并使用后端代理来处理后端并使用聚合物(vaadin)它正常工作,直到我更新到角度cli 1.0.0-beta.22它给出错误

Tried to find bootstrap code, but could not. Specify either statically analyzable bootstrap code or pass in an entryModule to the plugins options.

proxy.conf.json

{
  "/api": {
    "target": "http://127.0.0.1:3000",
    "secure": false
  }
}

主polymer.ts

document.addEventListener('WebComponentsReady', () => {
  require('./main.ts');
});

main.ts

import './polyfills.ts';

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { environment } from './environments/environment';
import { AppModule } from './app/';

if (environment.production) {
  enableProdMode();
}

// platformBrowserDynamic().bootstrapModule(AppModule);
platformBrowserDynamic().bootstrapModule(AppModule);

我怎么能纠正这个？

我在官方网站上有以下角度文档.但在文档测试中,部分已过时,无法使用当前的角度2 beta版本.我需要编写一个基本测试来检查if条件是否正常工作.我怎么能用角度2中的茉莉花做到这一点.

我正在使用angular2创建应用程序,我需要从雅虎天气获得天气.我尝试使用http get方法,但它给了我一个错误.

import {Component,OnInit,} from "angular2/core";
import {Http}       from "angular2/http";
import 'rxjs/add/operator/map';

@Component({
   templateUrl:'app/contact/contact.html',
})

export class ContactComponent{
     constructor (private http: Http) {}
     public url:string= "http://weather.yahooapis.com/forecastjson?w=2295424";

     ngOnInit(url:string) { 

        return this.http.get(url).map(res => {
                      return res.json();
                   }).subscribe((response) => { console.log(response) });

 }

}

我得到的错误是

EXCEPTION:SyntaxError:JSON.parse:JSON数据第1行第1列的意外字符

谁能帮我这个？.
