A way to get username from http requests on windows environment!

NOTE: this implementation is a transcript from java at this link: https://www.rgagnon.com/javadetails/java-0441.html

Features

Now, when you are working with ldap, you can get user information from http requests and after you can query ldap to get more user informations from dart!

Installing

Add ntlm request to your pubspec.yaml file:

dependencies:
  ntlm_request:

Import ntlm request in files that it will be used:

import 'package:ntlm_request/ntlm_request.dart';

Getting started

Just create an instance of ntlm request inside a route and start using it. Note that the return type of this is an object. I decided to not return a Response object directly to avoid fixing another package here. This way you can use any http packages you want, just insert the results into your response statusCode and headers!

    // inside your http route....
      RetType ret = ntlm.proccessRequest(req.headers);

      if (ret.statusCode != 200) {
        return Response(ret.statusCode, headers: ret.headers);
      }
      if (ret.statusCode == 200 && ret.userName!.isNotEmpty) {
        return Response.ok(ret.userName);
      }

Usage

  final appRouter = Router();

  appRouter.get('/api/getUserDetails', (Request req) async {
    NtlmRequest ntlm = NtlmRequest();
    RetType ret;
    try {
      ret = ntlm.proccessRequest(req.headers);

      if (ret.statusCode != 200) {
        return Response(ret.statusCode, headers: ret.headers);
      }
      if (ret.statusCode == 200 && ret.userName!.isNotEmpty) {
        return Response.ok(ret.userName);
      }
    } catch (e) {
      log(e.toString());
    }
    return Response(401,
        headers: {'error': 'ntlm user not identified in request header!'});
  });
