Update http Inject in app.module.ts

import {HttpModule, Http, XHRBackend, RequestOptions} from '@angular/http';

Inject files in app.module.ts and @NgModule:

import { HttpService } from '{route}/http.service.ts

import { httpFactory } from '{route}/http.factory.ts

  providers: [
    {
      provide: HttpService,
      useFactory: httpFactory,
      deps: [ XHRBackend, RequestOptions]
    }
  ],

Finally use in your service

import { Injectable } from '@angular/core';
import { Http, Headers} from '@angular/http';
import { Observable } from 'rxjs/Rx';
import 'rxjs/add/operator/map';

import { HttpService } from '../../core/http.service';

@Injectable()
export class HomeService {
  constructor(
    private http: HttpService
  ) {  }

  getTodos() {
    return this.http.get('todos')
  }
}
