我在登录应用程序时尝试设置用户信息，当我进入个人资料页面时，我试图检索数据。

使用单独的服务设置和获取用户信息

import { HttpClient, HttpParams } from '@angular/common/http';
import { Injectable, EventEmitter } from '@angular/core';
import {Storage} from '@ionic/storage';

@Injectable()
export class LoginService {

    private loginUrl = UrlService.APIURL+'/login/';
    userEvent: EventEmitter<any> = new EventEmitter();

    constructor(private http: HttpClient,
                private storage:Storage) { }


    public setStorageUser(user:any){

         return this.storage.set('user', user);

    }
    public getStorageUser():Promise<any>{

            return this.storage.get('user');

    }




}

登录页面上的设置值

this.loginService.setStorageUser(userData).then(()=>{

        this.navController.setRoot(HomePage);

        });

在个人资料页面上检索用户数据

this.loginService.getStorageUser().then((user)=>{
       console.log(JSON.stringify(user));
    });

我的应用程序上的应用程序模块页面

import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule } from '@angular/common/http';
import { ErrorHandler, NgModule } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';

@NgModule({

    HomePage,
    LoginPage,
    SideMenuPage,
    FavoritePage,

    ChannelPage,
    RegisterPage,
    PaymentPage,
    ProfilePage
  ],
  imports: [

    IonicModule.forRoot(MyApp),
    IonicStorageModule.forRoot()

  ],
  bootstrap: [IonicApp],
  entryComponents: [

    HomePage,
    LoginPage,
    SideMenuPage,
    CategoryPage,

    PlayerPage,
    ChannelPage,
    RegisterPage,
    PaymentPage,
    ProfilePage
  ],
  providers: [

    File,
    FileTransfer,
    StatusBar,
    SplashScreen,
    AppAvailability,
    AndroidExoplayer,
    InAppBrowser,
    {provide: ErrorHandler, useClass: IonicErrorHandler},
    FileServiceProvider,
    LoginService,
    CategoryService,
    ChannelService,
    SubscriptionService,
    UserService,
     PayPal
  ]
})
export class AppModule {}

我总是得到空用户，帮助！
