typescript – CORS策略：在离子2中请求的资源上没有“Access-Control-Allow-Origin”标头

我是混合开发的新手.我将这个Sample称为使用ionic2在listview中解析json.但是当我运行代码时,我只能看到浏览器中的空白屏幕.

下面我发布了代码.请检查 ：

pages.ts：

import { Component } from '@angular/core';
import {http} from '@angular/http';
import { NavController } from 'ionic-angular';
import 'rxjs/add/operator/toPromise';
@Component({
  SELEctor: 'page-home',templateUrl: 'pages.html'
})
export class SlidingPage {
public items:any;
  constructor(public navCtrl: NavController,public http: http) {
      this.http = http;
        this.http.get("http://api.randomuser.me/?results=10")
            .subscribe(data =>{

             // console.log(data['_body']);

          //   this.items=JSON.parse(data['_body']).results;//Bind data to items object

            this.items = data.json();


            },error=>{
                console.log(error);// Error getTing the data
            } );
  }
buttonClick(event){
   console.log("button clicked");
   console.log(event);
  }
  itemClicked(event,itemData){
    console.log("item clicked");
    console.log(event);
    console.log(itemData);
  }
}

Pages.html：

<ion-header>
  <ion-navbar>

    <ion-title>
     List View
    </ion-title>

  </ion-navbar>
</ion-header>

<ion-content padding>
<ion-list>
    <ion-item *ngFor="let item of items" (click)="itemClicked($event,item)">

     <ion-avatar item-left>
        <img src="{{item.picture.thumbnail}}">
      </ion-avatar>

      <h2>{{item.name.first | uppercase }}</h2>
      <h3>{{item.gender}}</h3>
      <ion-icon *ngIf="item.gender=='female'" name="woman" item-left></ion-icon>
      <ion-icon *ngIf="item.gender=='male'" name="man" item-left></ion-icon>
      <ion-icon name="heart" item-right></ion-icon>

      <button ion-button item-right color="danger" (click)="buttonClick($event)">Button</button>

    </ion-item>
  </ion-list>
</ion-content>

我在Console中遇到了这个问题：

localhost/:1 XMLhttprequest cAnnot load http://api.randomuser.me/?results=10. Redirect from 'http://api.randomuser.me/?results=10' to 'https://api.randomuser.me/?results=10' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access.

任何帮助表示赞赏.
