Download file with a REST request needing headers and giving the content

Question

I am using AngularJs with a REST API. I don't have the hand on the REST API. I can store digital object with the API by sending a REST request. I can get it also with a GET request. The requests needs to have some specific headers. My goal is to give the user a "download and save as" link. For now on the click event i make the request : ``` this.file = function (file) { var url = config.domain + 'file/' + file; var methods = resource(url, null, { 'get': { method:'GET', headers:{ 'Authorization' : user.auth, 'secret-key' : user.secretkey} } transformResponse : function(data, headersGetter){ return {content:data}; //transform octet stream into text, angular returns an array containing 1 character per element. }, }); return methods; }; ``` in the return body I have the file content (see below). I would like to download it. How is it possible ? Notice that I can't store the file as a URL. Would it be possible to open a window wich make the rest call with the good headers and save the file…

Accepted Answer

Thanks everybody for helping find a solution.

I am not able to find a satisfying solution in javascript and client side application. I am going to make a proxy class communicating with the API.

This will send the REST request with security headers and will give as response the file content.

This class will be called by a HTTP GET request, so the 'save as' process will be managed easily thanks to right response headers.
