getting 401 while authenticating.

I am using the following code :

require 'oauth'
require 'net/http'
require 'uri'
require 'json'
require 'securerandom'
require 'openssl'

class SchemeDataImporter
  attr_reader :script_id, :deploy_id, :realm, :consumer, :token

  def initialize(script_id, deploy_id, realm, consumer_key, consumer_secret, token, token_secret)
    @script_id = script_id
    @deploy_id = deploy_id
    @realm = realm
    @token_secret = token_secret
    @callback_url = "https://#{realm}.xyz.netsuite.com/app/site/hosting/xyz.nz?script=#{script_id}&deploy=#{deploy_id}"
    @consumer = OAuth::Consumer.new(consumer_key, consumer_secret, {
      site: "https://#{realm}.xyz.netsuite.com", 
      signature_method: 'HMAC-SHA256',
      oauth_version: '1.0' 
    })

    @token = OAuth::AccessToken.new(@consumer)
    
  end

  def import_data
    url = "/app/site/hosting/xyz.nz?script=#{script_id}&deploy=#{deploy_id}"
    
    # Generate OAuth header
    auth_header = generate_auth_header(url)
    response = @token.request(:get, "/app/site/hosting/xyz.nz?script=#{OAuth::Helper.escape(script_id)}&deploy=#{OAuth::Helper.escape(deploy_id)}")
    # response = @token.get(url, {
    #   'Authorization' => auth_header,
    #   'Content-Type' => 'application/json',
    #   'Accept' => 'application/json'
    # })

I am using ruby '2.4.6' & rails '5.2.3'

i am using the same creds in postman and its working there.

There is a lot of information missing. What version of the gem are you using?

[pboling]

Also please fix your code fences. They are the triple backticks you put around multi-line blocks of code. It is very hard to read.

  ` ` ` # but without spaces in between
  # Code goes here
  ` ` ` # again, without the spaces in between

Update: I fixed them for you! Much more readable now 😄

@archana-codezen I used your example as the basis for a complete working E2E example:
ruby-oauth/oauth2#680

[pboling]

Lol, I mixed this up with the oauth2 repo... Adding a similar example to the this repo now.
