javascript - Can't get headers from Http POST request with Axios -

i have post request axios in react :

postrunsimulation(simulationid) {   var requestanalysis = `${configfile.web.backend}analysis/${simulationid}/run`;   return axios.post(requestanalysis)   .then(function (response) {     return response.headers;   }, function(error) {     throw new error('an error occurred : ' + error.status + ' - ' + error.statustext);   }); }, 

the object in return has headers property it's empty. if make same call postman, headers. doing wrong ?

if back-end running on different host or port web app, browser can access following 6 response headers default: cache-control, content-language, content-type, expires, last-modified, , pragma (see this answer). if server not return of them, headers empty.
