How to make AJAX call with angular2(ts)? I read the tutorial on angularjs.org. But there is nothing about AJAX. So I really want to know how to make AJAX call with angular2(ts).

推荐答案

您将需要查看 api http模块的文档. http 类可以使用AJAX为您获取资源.有关更多示例，请参见Angular HttpClient指南.

import { Component } from '@angular/core';
import { Http } from '@angular/http';

@Component({
  selector: 'http-app',
  templateUrl: 'people.html'
})
class PeopleComponent {
  constructor(http: Http) {
    http.get('people.json')
      // Call map on the response observable to get the parsed people object
      .map(res => res.json())
      // Subscribe to the observable to get the parsed people object and attach it to the
      // component
      .subscribe(people => this.people = people);
  }
}
