注:鸿蒙的远程交互组件应用相对复杂 ,访问网络时,首先要配置网络权限,华为官方文档有问题,在此引用我老师配置的模板,见附件
过程:1.导入鸿蒙的网络请求模块fetch
2.发起对服务器的请求(在这过程中需要用JSON.parse将括号中的数据转换成json数据格式,具体见代码中标注)
js业务逻辑层
- //导入鸿蒙的网络请求模块fetch
- import fetch from '@system.fetch';
- export default {
- data: {
- title: 'World',
- currentTime:'',
- temperature1:'',
- text:'',
- },
- onInit() {
- //发起对心知天气服务器的请求
- fetch.fetch({
- url:'https://api.seniverse.com/v3/weather/now.json?key=S0YbU_VLcvXz-4LZx&location=成都&language=zh-Hans&unit=c',
- responseType:'json',
- success:(resp)=>{
- //JSON.parse(字符串)转换成json数据格式
- let weatherInfo=JSON.parse(resp.data);
- this.currentTime=weatherInfo.results[0].last_update;
- this.text=weatherInfo.results[0].now.text;
- this.temperature1=weatherInfo.results[0].now.temperature;
- }
- });
- }
- }
渲染层
- <div class="container">
- <text class="time">
- {{currentTime}}{{temperature1}}
- </text>
- <text class="time">
- {{temperature1}}
- </text>
- <text class="time">
- {{text}}
- </text>
- </div>
css样式属性设置
- .container {
- display: flex;
- justify-content: center;
- align-items: center;
- left: 0px;
- top: 0px;
- width: 454px;
- height: 454px;
- }
- .time {
- font-size: 50px;
- text-align: center;
- width: 200px;
- height: 1200px;
- }

微信小程序的远程交互应用:
js业务逻辑层

- //微信小程序请求天气
- wx.request({
