ionic 2 添加service

1.myService.js

import {Injectable} from 'angular2/core';

@Injectable()
export class myService {
    constructor() {
    }
    public test() {
        console.log("test my service");
    }
}

2.app.js

import {myService} from './services/myService';

@App({
  templateUrl: 'app/app.html',
    providers: [myService]
})

3.MyComponent.js

import {myService} from './services/myService';

export class MyComponent {

constructor(public service: myService) {

}

}

上述方法在最新的RC版本中已经不再适用，请参考官方最新文档。

注：

1.public service: myService等于

 this.service = service

2.如果引用Http，则需要同时引用HTTP_PROVIDERS
