The response headers in case of cors remain hidden  You need to add in response headers to direct the Angular to expose headers to javascript      From server response headers   header  Access-Control-Allow-Methods  GET  POST  OPTIONS    header  Access-Control-Allow-Headers  Origin  X-Requested-With   Content-Type  Accept  Authorization  X-Custom-header    header  Access-Control-Expose-Headers  X-Custom-header    header  X-Custom-header   some data     var data   res headers get  X-Custom-header      Source   https   github com angular angular issues 5237

Why not simply try this   var promise    http get url        params  query    then function response      console log  Content-Range      response headers  Content-Range       return response data        Especially if you want to return the promise so it could be a part of a promises chain

response headers      will give you all the headers  defaulat  amp  customs   worked for me         Note      I tested on the same domain only  We may need to add Access-Control-Expose-Headers header on the server  for cross domain

According the MDN custom headers are not exposed by default  The server admin need to expose them using  Access-Control-Expose-Headers  in the same fashion they deal with  access-control-allow-origin   See this MDN link for confirmation  https   developer mozilla org en-US docs Web HTTP Headers Access-Control-Expose-Headers

Use the headers variable in success and error callbacks  From documentation    http get   someUrl      success function data  status  headers  config           this callback will be called asynchronously        when the response is available         error function data  status  headers  config           called asynchronously if an error occurs        or server returns response with an error status          If you are on the same domain  you should be able to retrieve the response headers back  If cross-domain  you will need to add Access-Control-Expose-Headers header on the server   Access-Control-Expose-Headers  content-type  cache
