httpntlm

httpntlm is a Node.js library to do HTTP NTLM authentication

It's a port from the Python libary python-ntml

Install

You can install httpntlm using the Node Package Manager (npm):

npm install httpntlm

How to use

var httpntlm = require('httpntlm');

httpntlm.get({
    url: "https://someurl.com",
    username: 'm$',
    password: 'stinks',
    workstation: 'choose.something',
    domain: ''
}, function (err, res){
    if(err) return err;

    console.log(res.headers);
    console.log(res.body);
});

It supports http and https.

Options

  • url: {String} URL to connect. (Required)
  • username: {String} Username. (Required)
  • password: {String} Password. (Required)
  • workstation: {String} Name of workstation or ''.
  • domain: {String} Name of domain or ''.

You can also pass along all other options of httpreq, including custom headers, cookies, body data, ... and use POST, PUT or DELETE instead of GET.

Advanced

If you want to use the NTLM-functions yourself, you can access the ntlm-library like this (https example):

var ntlm = require('httpntlm').ntlm;
var async = require('async');
var httpreq = require('httpreq');
var HttpsAgent = require('agentkeepalive').HttpsAgent;
var keepaliveAgent = new HttpsAgent();

var options = {
    url: "https://someurl.com",
    username: 'm$',
    password: 'stinks',
    workstation: 'choose.something',
    domain: ''
};

async.waterfall([
    function (callback){
        var type1msg = ntlm.createType1Message(options);

        httpreq.get(options.url, {
            headers:{
                'Connection' : 'keep-alive',
                'Authorization': type1msg
            },
            agent: keepaliveAgent
        }, callback);
    },

    function (res, callback){
        if(!res.headers['www-authenticate'])
            return callback(new Error('www-authenticate not found on response of second request'));

        var type2msg = ntlm.parseType2Message(res.headers['www-authenticate']);
        var type3msg = ntlm.createType3Message(type2msg, options);

        setImmediate(function() {
            httpreq.get(options.url, {
                headers:{
                    'Connection' : 'Close',
                    'Authorization': type3msg
                },
                allowRedirects: false,
                agent: keepaliveAgent
            }, callback);
        });
    }
], function (err, res) {
    if(err) return console.log(err);

    console.log(res.headers);
    console.log(res.body);
});

Download binary files

httpntlm.get({
    url: "https://someurl.com/file.xls",
    username: 'm$',
    password: 'stinks',
    workstation: 'choose.something',
    domain: '',
    binary: true
}, function (err, response) {
    if(err) return console.log(err);
    fs.writeFile("file.xls", response.body, function (err) {
        if(err) return console.log("error writing file");
        console.log("file.xls saved!");
    });
});
