如何在Angular 2中为开发(而不是测试)提供模拟服务？

数据tables.service-interface.ts

export interface DataTablesServiceInterface {
    getHeaders(): Promise<any[]>;
    getData(query?: string,offset?: number,size?: number): Promise<any>;
}

数据tables.service-provider.ts

import { Http } from '@angular/http';
import { OpaqueToken } from '@angular/core';

import { DataTablesServiceInterface } from './data-tables.service-interface';
import { DataTablesService } from './data-tables.service';
import { DataTablesMockService } from './data-tables.mock-service';

import { environment } from '../../../environments/environment';

let dataTablesServiceFactory = (http: Http) => {
    var serviceToReturn: DataTablesServiceInterface;
    if (environment.production) {
        serviceToReturn = new DataTablesService(http);
    } else {
        serviceToReturn = new DataTablesMockService();
    }
    return serviceToReturn;
};

export let dataTablesToken = new OpaqueToken('DataTablesServiceInterface');

export let dataTablesServiceProvider =
    {
        provide: dataTablesToken,useFactory: dataTablesServiceFactory,deps: [
            Http
        ]
    };

您只需要实现实际和模拟服务,并可以根据已使用环境在angular-cli中实现的嵌入式配置文件机制来提供它们.

编辑：
还有一些我忘记提及的信息.在您的负责模块中,您需要将dataTablesServiceProvider声明为提供者.在您要使用该服务的组件中,DI的方法与标准方法略有不同.

在组件的构造函数中,您编写以下内容：

constructor(@Inject(dataTablesToken) private dataTablesService: DataTablesServiceInterface)

如果您对不透明的令牌感兴趣,我建议您查看Opaque Token by Angular
