Angular数据请求的实现方法

import { HttpModule, JsonpModule } from '@angular/http'

imports: [
 HttpModule,
 JsonpModule
],

import { Http, Jsonp } from '@angular/http'

constructor(private http: Http, private jsonp: Jsonp) { }

// 进行注入，拿到相对应的方法
constructor(private http: Http, private jsonp: Jsonp) { }
public list: any = []
// 请求数据
getData() {
 let url = 'http://www.phonegap100.com/appapi.php&＃63;a=getPortalList&catid=20&page=1'
 let _this = this
 this.http.get(url).subscribe((data) => {
  _this.list = JSON.parse(data['_body'])['result']
  console.log(_this.list)
 })
}

get 请求数据

 

  {{item.title}}
 

// 请求数据
jsonpData() {
 let url = 'http://www.phonegap100.com/appapi.php&＃63;a=getPortalList&catid=20&page=1&callback=JSONP_CALLBACK'
 let _this = this
 this.jsonp.get(url).subscribe((data) => {
  _this.list = data['_body']['result']
  console.log(_this.list)
 })
}

// 渲染
jsonp 请求数据

 

  {{item.title}}
 

import { Http, Jsonp, Headers } from '@angular/http'

private headers = new Headers({'Content-Type': 'application/json'})

postData() {
 let url = 'http://localhost:8080/login'
 let data = {
  "username": "zhangsan",
  "password": "123"
 }
 this.http.post(
  url,
  data,
  {headers: this.headers}
 ).subscribe((data) => {
  console.log(data)
 })
}
