鸿蒙开发(二)：使用ArkTS实现HTTP请求功能：GET与POST请求的封装 原创

import http from '@ohos.net.http';

export function httpRequestGet(url: string, params?: string)
  return httpRequest(url, http.RequestMethod.GET, params);

readTimeout: 10000, // 读取超时时间，可选

extraData: params

  let getjson: string = '';
  return responseResult.then((value: http.HttpResponse) =>
