java - Jersey REST client - multipart creation - not from File object -


i guess there no other way creating filedatebodypart providing file object:

public filedatabodypart(string name, file fileentity)

but in case have byte[] , don't want convert file , store on filesystem.

is there other way of generating multipart (while uploading file) array of byte, inputstream... in worst case using other client library?

update: here working code (but want use byte[] instead of file):

filedatabodypart filepart = new filedatabodypart("attachment", new file("c:/temp/test.txt")); multipart multipart = new formdatamultipart().bodypart(filepart); invocation.builder invocationbuilder = webtarget.request().accept(mediatype.application_json); response response = invocationbuilder         .buildpost(entity.entity(multipart, mediatype.multipart_form_data))         .invoke();

there's no other way filedatabodypart not accept file.

as workaround, might want create temporary file , delete once jvm exits:

byte[] bytes = {1, 2, 3};  file tempfile = file.createtempfile("filename", null); tempfile.deleteonexit();  fileoutputstream fos = new fileoutputstream(tempfile); fos.write(bytes); fos.close();  filedatabodypart filepart = new filedatabodypart("attachment", tempfile);

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
