如何使用鸿蒙代码去与后台连接请求！

import http from '@ohos.net.http'
@Entry
@Component
struct Interface {
  @State message: string = 'Hello World'
  @State from: string = ''
  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
      }
      .width('100%')
    }
    .height('100%')
  }
  aboutToAppear(){
    //1.创建http对象 (在这之前需要再moudule.json5文件配置网络权限)
    let httpRequest = http.createHttp()
  //   2.发起请求
    httpRequest.request("https://api.apiopen.top/api/sentences",{
      method:http.RequestMethod.GET,
    },(err,data)=>{
      if (!err) {
        this.message = JSON.parse(`${data.result}`).result.name
        this.from = JSON.parse(`${data.result}`).result.from
      }
    })
  }
}

自己拉的在线的接口，试一下吧！
