Http请求中的Post 请求，如何将extraData作为参数传递使用

httpRequestPostDoMain(domain:string,url: string,object:object): Promise<CkResponseResult> { 
  let httpRequest = http.createHttp(); 
  let responseResult = httpRequest.request(url, { 
    method: http.RequestMethod.POST, 
    readTimeout: Constant.NETWORK_TIME_OUT, 
    header: { 
      'Content-Type':'application/json; charset=UTF-8', 
      //TODO 用户信息需要后面补充 
      'userToken': '', 
      'Cookie':'', 
      'token':'', 
      'Terminal':'HuaWei', 
      'Accept-Encoding':'gzip, deflate', 
      'Accept':'application/json,text/javascript,*/*;charset=UTF-8', 
    }, 
    connectTimeout: Constant.NETWORK_TIME_OUT, 
    extraData:object 
  }); 
  let serverData: CkResponseResult = new CkResponseResult(); 
  return responseResult.then((value: http.HttpResponse) => { 
  //接口请求成功 
  if (value.responseCode === 200) { 
  //获取返回的数据 
  let result = `${value.result}` 
  //转换JSON 
  let resultJson: CkResponseResult = JSON.parse(result) 
  // 
  if (resultJson.status ===  Constant.CK_NETWORK_YES) { 
  serverData.data = resultJson.data; 
} 
serverData.status = resultJson.status; 
serverData.msg = resultJson.msg; 
} else { 
  serverData.msg = '接口数据异常' +value.responseCode; 
} 
return serverData; 
}).catch(() => { 
  serverData.msg = '接口数据异常' 
  return serverData; 
}) 
} 
}
