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);
}
}
