如何在离子2中重新加载API URL

Question

将数据发布到API URL之后。我想刷新API URL以获取最后更新的数据

我称我的名字

this.http.get('api url here',{headers: headers}).map(res => res.json()).subscribe(data => {
                this.items=data;
            },
            err => {
                console.log('Err!')
            });

请给出任何建议

尝试以下：

添加提供商：

 @Injectable()
 export class ServiceProvider {
 baseUrl: string = 'https://...';
 constructor(public http: Http) {
  this.http = http;
 }
 getPosts(){
 return this.http.get(this.baseUrl)
  .map(res => res.json())
  .toPromise();// executa uma function e retorna JSON
 }

然后在家里：

 ngOnInit(){
   this.getPostsSite();
 }
 getPostsSite(){
   this.serviceProvider.getPosts().then(
     response => { 
       this.items = response.data.children
   });
 }
