import { JwtConfigService, JwtHttp } from 'angular2-jwt-refresh';

@NgModule({

    deps: [ Http, RequestOptions ]
  }]
})
export class AppModule {}

export function getJwtHttp(http: Http, options: RequestOptions) {
  let jwtOptions = {
    endPoint: 'https://myapi.domain.com/auth',

      return true;
    })
  };
  let authConfig = new AuthConfig({

}

Using JwtHttp

import { Injectable } from '@angular/core';
import { Response } from '@angular/http';
import { JwtHttp } from 'angular2-jwt-refresh';
import { Observable } from 'rxjs/Observable';
import 'rxjs/Rx';

import { AppConfig } from '../AppConfig';

@Injectable()
export class DataService {
  private baseUrl: string = AppConfig.baseUrl + '/data';

  constructor(private jwtHttp: JwtHttp) { }

  getData(id: number): Observable<any> {
    const url = this.baseUrl + '/' + id;

    return this.jwtHttp
      .get(url)
      .map((res: Response) => {
        return res.json();
      });
  }

  saveData(data: any): Observable<string> {
    const url = this.baseUrl + '/' (data['id'] ? data['id'] : '');

    return this.jwtHttp
      .post(url, data)
      .map((res: Response) => {
        return res.json();
      });
  }
