在本章中,您将学习如何在Aurelia框架中处理HTTP请求.
让我们创建四个按钮,用于向我们的API发送请求.
<template> <button click.delegate = "getData()">GET</button> <button click.delegate = "postData()">POST</button> <button click.delegate = "updateData()">PUT</button> <button click.delegate = "deleteData()">DEL</button> </template>
为了向服务器发送请求,Aurelia建议获取客户.我们正在为我们需要的每个请求创建函数(GET,POST,PUT和DELETE).
import 'fetch'; import {HttpClient, json} from 'aurelia-fetch-client'; let httpClient = new HttpClient(); export class App { getData() { httpClient.fetch('http://jsonplaceholder.typicode.com/posts/1') .then(response => response.json()) .then(data => { console.log(data); }); } myPostData = { id: 101 } postData(myPostData) { httpClient.fetch('http://jsonplaceholder.typicode.com/posts', { method: "POST", body: JSON.stringify(myPostData) }) .then(response => response.json()) .then(data => { console.log(data); }); } myUpdateData = { id: 1 } updateData(myUpdateData) { httpClient.fetch('http://jsonplaceholder.typicode.com/posts/1', { method: "PUT", body: JSON.stringify(myUpdateData) }) .then(response => response.json()) .then(data => { console.log(data); }); } deleteData() { httpClient.fetch('http://jsonplaceholder.typicode.com/posts/1', { method: "DELETE" }) .then(response => response.json()) .then(data => { console.log(data); }); } }
我们可以运行该应用并点击 GET , POST , PUT 和 DEL 按钮.我们可以在控制台中看到每个请求都成功,并记录结果.
