Remove these two lines:
xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");
XMLHttpRequest isn't allowed to set these headers, they are being set automatically by the browser. The reason is that by manipulating these headers you might be able to trick the server into accepting a second request through the same connection, one that wouldn't go through the usual security checks - that would be a security vulnerability in the browser.
// request interceptor
service.interceptors.request.use(
config => {
// do something before request is sent
// console.log(store.getters.token)
config.headers['Access-Control-Allow-Origin'] = '*'
config.headers['cache-control'] = 'max-age=1,s-maxage=1'
config.headers['Cookie'] = 'noBy-interceptors.request'
