How to save pdf in proper encoding via nodejs

Question

So I'm trying to download a pdf file from a website with my script but the problem is that the file gets broken in the process and I'm pretty sure it's because of wrong encoding being used.

I'm using request lib for downloading the file and I've set the Content-type to application-pdf

My code is pretty simple:4

var fs = require('fs');
var request = require("request");


request({uri: 'xxxxxxxxxxxxxx.pdf', headers: { 'Content-type' : 'applcation/pdf' }} , function (error, response, body) {
  if (!error && response.statusCode == 200) {
    fs.writeFileSync("10111.pdf", body);
  }
})

Where do I need to specify the encoding used for this to work?

I tried opening the pdf that I get by normal saving and SublimeText3 encodinghelper says it's in Windows-something while the one I downloaded is in utf8.

I've gone through the nodejs buffer and fs files and they do not supprt encodings like windows-asd, only the general ones like 'utf8' and 'binary'.

Should I maybe use a different method for obtaining the file?

I know its very late but i seen your question today so i am answering it so that other can get help from this. You can add the encoding when you are trying to write the file i.e-:

fs.writeFileSync("10111.pdf", body,'binary');

As i set encoding format as binary here you can use which is right encoding format according to your requirenment if you are trying to download a pdf that you can set encoding as null.

Hope this would help
