AUTH-service.ts

 public loginChef(credentials) { 
     if (credentials.email === null || credentials.password === null) { 
     return Observable.throw("Please insert credentials"); 
     } else { 
      return Observable.create(observer => { 

      var url = 'http://localhost/PFEBACKEND/login-chef.php? 
     email='+credentials.email+'&passe='+credentials.password ;   
      this.http.get(url).map(res => res.json()).subscribe(
      data=>{                  
       let access = (data.error=== 0) 
       localStorage.setItem('nom',data.nom_contact); 
       localStorage.setItem('nom_societe',data.nom_societe); 
        localStorage.setItem('email',data.email); 
        localStorage.setItem('telephone',data.telephone);

        observer.next(this.email,this.nom); 
        //observer.next(this.member); 
        //observer.next(access); 
        // console.log(this.currentUser); 
        observer.complete(); 
        },

offre.ts

 offres: Array<any>; 
     loader: any; 
     id:string=''; 


constructor(public navCtrl: NavController, public navParams: NavParams,

loadingCtrl:LoadingController) 
{

       this.id=localStorage.getItem('id');       
      } 

} 
    ngOnInit() 
    { var id1=parseInt(this.id).valueOf();// i get undefined value 
     this.presentLoading();  
     this.data.LoadOffres(id1).subscribe(
     //function LoadOffres accept int type parameter 
      data => { 
      this.offres = data; 
      console.log(data);    
      this.loader.dismiss(); 
     }, 
     err => { 
      console.log(err); 
      console.log(id1); 
      this.loader.dismiss(); 
     }, 
    () => console.log('chargement terminé') 
); 
}

auth.ts

 public loginChef() { 
     this.showLoading(); 
     this.auth.loginChef(this.registerCredentials).subscribe(allowed => { 
     if (allowed) { 
      setTimeout(() => { 

      this.email=this.auth.email; 
      this.nom=this.auth.nom; 
      this.currentUSer = this.auth.currentUser; 
      this.member=this.auth.member;//array 

      localStorage.setItem('email',this.email);

'if（localStorage.getItem（'id'））{//登录后我存储用户数据 this.id = localStorage.getItem（'id'）; }'你能够在这里记录数据吗？ –

当我试图登录ID我得到“undefined” –

你将不得不检查它是否被设置在存储中..'localStorage.setItem（'id'，data.id_chef）;'在这里登录..如果它不是这里然后服务器端... –

一切是正确的概率lem在我的服务器端代码
