Download file from NodeJS server adding header for content disposition
I have this server function that extract URL and Filename to files saved on external services.
Example - https://ec-media.sndcdn.com/ZtPlxyZHyzxy.128.mp3?f10880d39085a94a0418a7ef69b03d522cd6dfee9399eeb9a522059d69ffb9359bc7c231696809f40c29ddb8e488adfa7f7fccde067c557b3ae31730fc6901d18842314a30
I get url and filename to variables, but how do I set header 'Content-disposition', 'attachment'; filename = filename; and return it to client so it'll be downloadable with click.
// load future from fibers
var Future = Meteor.npmRequire("fibers/future");
// load youtubedl
var youtubedl = Meteor.npmRequire('youtube-dl');
// load fs
var fs = Meteor.npmRequire('fs');
// require request
var request = Meteor.npmRequire('request');
Meteor.methods({
'command' : function(line) {
// this method call won't return immediately, it will wait for the
// asynchronous code to finish, so we call unblock to allow this client
this.unblock();
var future = new Future();
youtubedl.getInfo(line, function(err, stdout, stderr) {
var url = stdout.url;
var filename = stdout._filename;
future.return({stdout: stdout, stderr: stderr});
});
return future.wait();
}
