将返回值从php api数组传递到另一页

在user.html页面中,我有一个按钮,当单击该按钮时,将值传递到下一页

<button ion-button icon-only (click)="goToResult()">
    <ion-icon ios="ios-log-out" md="md-log-out" class="user"></ion-icon> Next
</button>

ngOnInit(){

this.phone = this.navParams.get('phone');


var headers = new Headers();

headers.append("Accept", 'application/json');

headers.append('Content-Type', 'application/json' );

let options = new RequestOptions({ headers: headers });

let data = {

    phone: this.phone

     };

let loader = this.loading.create({

content: 'Loading Page Contents',

});

loader.present().then(() => {

this.http.post('http://mypro.com/eApi/retrieve.php',data, options)

.map(res => res.json())

    .subscribe(res => {

     loader.dismiss()

    this.items=res.server_response;

    console.log(this.items);

    });

    });
    //this.navCtrl.push(PostPage, data); 
  }

在同一页上,这是我试图传递值的push nav

goToResult(){
    console.log(this.items);
      this.navCtrl.push(PostPage,
        this.postList = this.items
      )

  }

this.navParams.get(this.postList);

然后在我的 post.html网站

<ion-title *ngFor="let post of postList">{{post.Name}}
        </ion-title>

请告诉我,如何将返回值从api传递到另一个页面?
