javascript - Request headers not sent from Service Worker -

-

i'm trying fetch web service service worker. service jsp secured basic apache authentication, must provide credentials authenticate in request headers. following request works fine main window:

self.addeventlistener('push', function(event) {   console.log('received push message', event);    event.waituntil(     fetch(online_site_endpoint, {     method: 'get',     mode: 'cors',     headers: {         'accept': 'application/json',         'authorization': 'basic btoa(auth info)'     }     }).then(function(response) {         //process response     }).catch(function(err) {      })   ); });

that code event.waituntil() scope, function called 'push' event listener. however, same exact call fails 401 (unauthorized). network panel developer tools shows headers not being sent:

options /latest-new.jsp http/1.1 host: {an accessible host} connection: keep-alive access-control-request-method: origin: http://localhost user-agent: mozilla/5.0 (x11; linux i686) applewebkit/537.36 (khtml, gecko) chrome/43.0.2357.134 safari/537.36 access-control-request-headers: accept, authorization accept: */* referer: http://localhost/service-worker.js accept-encoding: gzip, deflate, sdch accept-language: en-us,en;q=0.8

is there missing here? or can't achieved service worker?

some info: can't use xmlhttprequest since 'not defined' on service worker scope. headers on jsp before retrieving json:

response.setheader("access-control-allow-origin", "*"); response.setheader("access-control-allow-methods", "post, get, options, delete"); response.setheader("access-control-max-age", "3600"); response.setheader("access-control-allow-headers", "x-requested-with");

update: there authentication headers service workers, since requests non-secured urls not fails. same service without apache authorization works expected.

you should set allowed headers accept , authorization

response.setheader(   "access-control-allow-headers",    "x-requested-with, accept, authorization" );

also body of response "options" request should empty (it not necessary indeed, there no use case body in such response) , content-length: should 0 (zero)

please note, request should not passed application (you can, not need)
