How to make a rest call to SharePoint 2013 from node.js? - node.js

Question

In my node.js app, I want to make a rest call to sharepoint 2013. This is the node.js code
function downloadData(res, key, success, fail) {
var opts = url.parse(key);
opts.method = 'GET';
opts.headers = {"Accept":"application/json;odata=verbose","X-RequestDigest":"0x146E2BDC9A21FDA62E793A0FC9793A530A5C6688BE194FB051703C8529B01A16607931C77D26EE61FA360AD04526F476A052FAC9B3C9277A5463AC20A27C3543,07 Mar 2016 15:37:18 -0000"};
opts.headers['Content-Type'] = 'application/json;odata=nometadata';
var req = http.request(opts, function(response) {
var str = '';
//another chunk of data has been recieved, so append it to `str`
response.on('data', function (chunk) {
str += chunk;
});
//the whole response has been recieved, so we just print it out here
response.on('end', function () {
success(res, str, key);
});
})
//req.write(data);
req.end();
}
I got the digest value from the client side, I did an alert statement, and copied it. I tried it on a sample url, which does work if I paste on the browser. When I run this, I get 401 unauthorized.
Does anyone know what's wrong?
Thanks

First of all, X-RequestDigest Header is used to validate client requests but not for authentication purposes.
Assuming your SharePoint sites utilizes NTLM authentication (default), you could utilize httpntlm package that implements HTTP NTLM authentication flow and allows to perform HTTP requests as demonstrated below:
var credentials = {
username: 'jdoe',
password: 'password',
domain: 'contoso'
};
var webUrl = "http://contoso.intranet.com";
var fileUrl = "/Shared Documents/guide.docx";
httpntlm.get({
url: webUrl + "/_api/web/getfilebyserverrelativeurl('" + fileUrl + "')/$value",
username: credentials.username,
password: credentials.password,
domain: credentials.domain
}, function (err, res) {
if (err) console.log(err);
console.log(res.body); //print data
});
