使用Restangular请求从REST API下载文件

Question

I've got a simple node.js + Restify backend with standard CORS settings and this endpoint:

 var file = '1,5,8,11,12,13,176,567,9483'; server.get('/download', function(req, res, next) { res.set({"Content-Disposition": "attachment; filename='numbers.csv'"}); res.setHeader("Content-type", "text/csv"); res.send(file); return next(); }, function(err) { res.send(err); }); 

What it's suppose to do is to is to create CSV file and return it.

It works great when I simply type in the endpoint address to web browser and hit enter. The file gets downloaded properly.

But when I try to do the same thing, but instead of using browser's address bar I use Restangular like that:

 Restangular.one('download').get().then(function (res) { console.log(res); }); 

it just writes response to console, but no file is being downloaded.

Is there a way to do this using Restangular? Or maybe I need to use something else for this?

I am not sure if Restangular can do that, but I am using FileSaver script for stuff like that. Add Filesaver to your HTML head and then:

Restangular.one('download').get().then(function (res) {
    var file = new Blob([res], { type: 'text/csv' });
    saveAs(file, 'something.csv');
});
