send a post request with axios and send data using FormData in the format

jQuery
what"s the difference between the two? Because the first response is true, but it doesn"t seem to have been deleted yet!
export const delHandBook= params => {
return axios.post(`${base}/fileManage/deleteHandBook`, params, {headers: {"Content-Type": "application/x-www-form-urlencoded;charset=UTF-8"}}).then(res => res.data);
};
