import http from '@ohos.net.http'
@Entry
@Component
struct HttpPage {@State message: string = 'Hello World'build() {Column({space:20}) {Row(){Button('发送http请求').onClick(()=>{let httpRequest = http.createHttp();httpRequest.request('https://zzgoodqc.cn/index.php/index/qus/getquestionlist',{method:http.RequestMethod.POST,extraData:{sn:'1001'}}).then(resp=>{console.log("resp=>",JSON.stringify(resp))if(resp.responseCode === 200){console.log(resp.result.toString())}}).catch(err=>{console.log('请求错误err=>',err)})})}}.width('100%').height('100%')}
}

以上是方案1：默认数据请求

方案二：使用axios第三方库请求接口

第一步：安装aixos，执行

ohpm install @ohos/axios

第二步：注意配置网络权限，在module.json5文件中

    "requestPermissions":[{"name": "ohos.permission.INTERNET"}],

第三步：类似vue，正常引入使用

import axios from  '@ohos/axios'
@Entry
@Component
struct HttpPage {@State message: string = 'Hello World'build() {Column({space:20}) {Row(){Button('发送axios请求').onClick(()=>{axios.post('https://zzgoodqc.cn/index.php/index/qus/getquestionlist',{sn:'1001'}).then(response=>{console.log("response=>",JSON.stringify( response))}).catch(err=>{console.log('err=>',err)})})}}.width('100%').height('100%')}
}
