//postdata就是body参数(data)
export function postAction(url, parameter) {
  let sign = signMd5Utils.getSign(url, parameter);
  //将签名和时间戳，添加在请求接口 Header
  // update-begin--author:taoyan---date:20220421--for: VUEN-410【签名改造】 X-TIMESTAMP牵扯
  let signHeader = { "X-Sign": sign, "X-TIMESTAMP": signMd5Utils.getTimestamp() };
  // update-end--author:taoyan---date:20220421--for: VUEN-410【签名改造】 X-TIMESTAMP牵扯

  return axios({
    url: url,
    method: 'post',
    data: parameter,
    headers: signHeader

//post请求query传参(params)
export function postActionsdata(url, parameter) {
  let sign = signMd5Utils.getSign(url, parameter);
  //将签名和时间戳，添加在请求接口 Header
  // update-begin--author:taoyan---date:20220421--for: VUEN-410【签名改造】 X-TIMESTAMP牵扯

一般在manage.js里

vue3中一般post请求是body传参改变传参方式需要

export const upfileTransfer = (params) => {
  return defHttp.post({ url: Api.fileTransfer, params }, { joinParamsToUrl: true, isReturnNativeResponse: true });
};
// isReturnNativeResponse: true 这个参数会返回的完整的响应体 你按照返回的code判断 然后取对应的值 进行判断 

然后在调用页面

//正常是editopen({需要传递的参数})
editopen({ id: data.record.id })
      .then((res) => {
        console.log(res);
      })
//需要去掉大括号upfileTransfer(需要传递的参数)
upfileTransfer(params)
        .then(res => {
          console.log('res', res);
          if (res.data.code == 200) {
            $message.success(res.data.message);
          } else {
            $message.warning(res.data.message);
          }
        })
