ionic2 using storage to store json object

I am getting the json from a REST API, and want to store it for other page to use, but when I build it , it have a error below:

Runtime Error Can't resolve all parameters for LoginPage: ([object Object], [object Object], [object Object], [object Object], [object Object], [object Object], ?).

And below is my code of login.ts:

import { Component } from '@angular/core';
import { NavController, LoadingController, ToastController } from 'ionic-angular';
import { FormBuilder, Validators } from "@angular/forms";
import { AuthService } from '../../providers/auth-service/auth-service';
import { NavParams } from 'ionic-angular';
import { MePage } from '../me/me';
import { IonicStorageModule } from '@ionic/storage';

@Component({
  selector: 'page-login',
  templateUrl: 'login.html'
})
export class LoginPage {
  loginData = { email:'', password:'', deviceToken:'testingDT', os:'ios', appVersion:'3.0.0' };
  authorize: string;

  constructor(public navCtrl: NavController, private navParams: NavParams, public authService: AuthService, public loadingCtrl: LoadingController, private toastCtrl: ToastController, public _form:FormBuilder, public storage: Storage) {}

 doLogin() {
    this.authService.login(this.loginData).then(data => {
      console.log("CHECKING: ",data.name);
      this.storage.set('user', JSON.stringify(data));
    }, (err) => {
    });
 }
}

Does anyone known what the problem is? Thanks a lot.

auth-service.ts:

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

let apiUrl = localStorage.getItem('domain');

@Injectable()
export class AuthService {

  data:any;

  constructor(public http: Http) {}

  login(credentials) {

  if(this.data){
    return Promise.resolve(this.data);
  }

  let opt: RequestOptions;
  let myHeaders: Headers = new Headers;

  myHeaders.set('Accept', 'application/json; charset=utf-8');
  myHeaders.append('Content-type', 'application/json; charset=utf-8');
  opt = new RequestOptions({
    headers: myHeaders
  })

  return new Promise(resolve => {
  this.http.get(apiUrl+'login?email='+credentials.email+'&password='+credentials.password+'&deviceToken='+credentials.deviceToken+'&os='+credentials.os+'&appVersion='+credentials.appVersion, opt)
    .map(res => res.json())
    .subscribe(data => {
      this.data = data;
      resolve(this.data);
    });
   });
}
