Typescript Angular 2将int注入一个服务，然后将该服务注入另一个服务

我有两个组件和三个服务：

• team-cards.component
• 选择-cards-display.component
• 信用卡服务
• http-cards.service
• http-team-cards.service

选择卡片显示。组件为自己提供
选择卡片。服务
，
选择卡片。服务
通过依赖项注入获取一个
http选择卡片。服务

选择卡片显示。组件

import {Component} from 'angular2/core';
import {ChoosesCardsService} from './Services/chooses-cards.service';
import {ICard} from './Commons/ICard.interface';

@
Component({
    selector: 'chooses-cards-display',
    templateUrl: './templates/ChooseCardComponent/choose-card-display.tpl.html',
    providers: [ChoosesCardsService]
})
export class ChooseCardDisplayComponent {
    private _cards: Array<ICard>;
    public _amount: number;
    public _skip: number; 

    constructor(private _choosesCardService: ChoosesCardsService) {
        this._amount = 3;
        this._skip = 0;
        this._cards = new Array<ICard>();
        this._choosesCardService.getChoosesCards(this._amount, this._skip).forEach(card => {
            console.log("CCDC hi!", card);
            this._cards.push(card);
            console.log("CCDC bye!");
        });
    }
}

import {Component} from 'angular2/core';
import {provide} from 'angular2/core';
import {Input} from 'angular2/core';
import {HttpTeamChoosesCardsService} from './Services/http-team-chooses-cards.service';
import {HttpChoosesCardsService} from './Services/http-chooses-cards.service';

@Component({

    template: `<chooses-cards-display></chooses-cards-display>`,
    directives: [ChooseCardDisplayComponent],
    inputs: ['teamID : given_teamID'],
    providers: [provide(HttpChoosesCardsService, { useClass: HttpTeamChoosesCardsService, useValue: this.teamID})]
})
export class TeamChooseCardComponent {
    @Input('given_teamID') teamID: number;
    constructor() {
        console.log("from teamcomponeny ", this.teamID);
    }
}

http选择卡片。service

是一个抽象类，我提供给

选择卡片。service

是它的一个扩展名为

http团队选择卡片。service

http团队选择卡片。服务

import {Injectable} from 'angular2/core';
import {HttpChoosesCardsService} from './http-chooses-cards.service';
import {HttpUserService} from '../../global/global.services';
import {IUser} from '../../Global/global.commons';
import {ICard} from '../Commons/ICard.interface';
import {CardFactory} from '../Commons/CardFactory.class'


@Injectable()

export class ChoosesCardsService {
    constructor(private _httpChoosesCardsSrvice: HttpChoosesCardsService, private _httpUserSrvice: HttpUserService) {
    }

    getChoosesCards(amount: number, skip: number): Array<ICard> {
        var ret = new Array<ICard>();
        this._httpChoosesCardsSrvice.getChoosesCards(amount, skip).forEach(cardInfo => {
            console.log("CCS hi: ", CardFactory.create(this._httpUserSrvice.getUserById(cardInfo.userId), cardInfo.projectName,
                cardInfo.description, cardInfo.likes));
            ret.push(CardFactory.create(this._httpUserSrvice.getUserById(cardInfo.userId), cardInfo.projectName,
                cardInfo.description, cardInfo.likes));
            console.log("CCS bye!");
        });
        return ret;
    }
}

import {Injectable} from 'angular2/core';
import {ICard} from '../Commons/ICard.interface';

@Injectable()
export abstract class HttpChoosesCardsService {
    abstract getChoosesCards(amount: number, skip: number): any ;
}

import {Injectable} from 'angular2/core';
import {HttpChoosesCardsService} from './http-chooses-cards.service';

@Injectable()
export class HttpTeamChoosesCardsService extends HttpChoosesCardsService{

    constructor(private _teamID: number) { super(); console.log("from teamService ", this._teamID);}

    getChoosesCards(amount: number, skip: number): any {
        //Mock data.
        var ret = new Array<any>();
        ret.push({
            "userId": 12,
            "projectName": "Bama",
            "description": "Bama is good",
            "likes" : 100
        });
        ret.push({
            "userId": 2,
            "projectName": "Bama2",
            "description": "Bama2 is Bad",
            "likes": 5
        });
        return ret;
    }
}

首先，如果我的逻辑是错误的，如果有人能告诉我一种不同的方式或更好的架构，我会很感激，如果没有，我会很乐意回答有关架构的问题

现在，当我在

团队选择卡片.组件中提供时，我想向
http团队选择卡片.服务
注入一个数字

有人能发现我做错了什么吗

谢谢。
这是不是像
如果一只土拨鼠能扔木头，一只土拨鼠会扔多少木头这样的谜题呢？
，我很抱歉，我弄糊涂了。我的魔杖a chooses-cards-display.component使用chooses-cards.service，它使用http-chooses-cards.service。现在我想注入http-team-choices-cards.service，而不是http-choices-cards.service。我是在团队卡上做的，明白了吗？别把我当回事。如果我不这么做，其他人会的。附言：我要去麦迪屯英雄联盟
