Authentication Token Error Rails
Contents |
token based authentication for connecting with their web API, like HipChat, Campfire, rails token authentication gem Backpack, Last.fm and many others. It’s not yet a rails token authentication devise standard, but there is an official draft that specifies the scheme. Token based authentication offers rails token authentication from scratch many benefits over HTTP Basic and Digest Authentication: More convenience, as we can easily expire or regenerate tokens without affecting the user’s account password. rails api token authentication Better security if compromised, since vulnerability is limited to API access and not the user’s master account. The ability to have multiple tokens for each user, which they can use to grant access to different API clients. Greater control for each token, so different access rules can be implemented.
Rails Devise Authentication Token Example
Getting an API token usually means visiting a profile settings page on the service’s website and requesting an access key. Some might already have a key generated for us. The Authorization header format for Token based authentication looks like so: GET /episodes HTTP/1.1 Host: localhost:3000 Authorization: Token token=123123123 Rails Authentication Rails offers the authenticate_or_request_with_http_token method, which automatically checks the Authorization request header for a token and passes it as an argument to the given block: authenticate_or_request_with_http_token do |token, options| # authenticate user... end Inside that block is where we implement our authentication strategy. In the following example, we’ll authenticate our requests for the EpisodesController class. class EpisodesController < ApplicationController before_action :authenticate def index episodes = Episode.all render json: episodes
ApplicationController TOKEN = "secret" before_action :authenticate, except: [ :index ] def index render plain: "Everyone can see me!" end def edit
Rails Http Authentication Token
render plain: "I'm only accessible if you know authentication token error hit it rich the password" end private def authenticate authenticate_or_request_with_http_token do |token, options| # Compare the rails api authentication devise tokens in a time-constant manner, to mitigate # timing attacks. ActiveSupport::SecurityUtils.secure_compare( ::Digest::SHA256.hexdigest(token), ::Digest::SHA256.hexdigest(TOKEN) ) end end end Here is a more https://www.codeschool.com/blog/2014/02/03/token-based-authentication-rails/ advanced Token example where only Atom feeds and the XML API is protected by HTTP token authentication, the regular HTML interface is protected by a session approach: class ApplicationController < ActionController::Base before_action :set_account, :authenticate protected def set_account @account = Account.find_by(url_name: request.subdomains.first) end http://api.rubyonrails.org/classes/ActionController/HttpAuthentication/Token.html def authenticate case request.format when Mime[:xml], Mime[:atom] if user = authenticate_with_http_token { |t, o| @account.users.authenticate(t, o) } @current_user = user else request_http_token_authentication end else if session_authenticated? @current_user = @account.users.find(session[:authenticated][:user_id]) else redirect_to(login_url) and return false end end end end In your integration tests, you can do something like this: def test_access_granted_from_xml get( "/notes/1.xml", nil, 'HTTP_AUTHORIZATION' => ActionController::HttpAuthentication::Token.encode_credentials(users(:dhh).token) ) assert_equal 200, status end On shared hosts, Apache sometimes doesn't pass authentication headers to FCGI instances. If your environment matches this description and you cannot authenticate, try this rule in your Apache setup: RewriteRule ^(.*)$ dispatch.fcgi [E=X-HTTP_AUTHORIZATION:%{HTTP:Authorization},QSA,L] Namespace MODULE ActionController::HttpAuthentication::Token::ControllerMethods Methods A authenticate, authentication_request E encode_credentials P params_array_from R raw_params, rewrite_param_values T token_and_options, token_params_from Constants TOKEN_KEY = 'token=' TOKEN_REGEX = /^(Token|Bearer)\s+/ AUTHN_PAIR_DELIMITERS = /(?:,|;|\t+)/ Instance
Securing an API May 23, 2012 | 7 minutes | Security, APIs There are many approaches to locking down an API. Here I start http://railscasts.com/episodes/352-securing-an-api?view=asciicast off with HTTP Basic authentication then move on to generating a unique http://www.airpair.com/ruby-on-rails/posts/authentication-with-angularjs-and-ruby-on-rails token which can be passed through a URL parameter or HTTP header.

We can interact with this application through JSON if we visit the path /api/products. This API is completely public so anyone can use it to edit or destroy the products but usually we want to restrict access to an rails token authentication API. There are a variety of ways that we can do this and the correct technique depends on our application’s requirements. In this episode we’ll show several solutions that we can use to lock down an API so that you can choose the one that best fits your style of application. Using HTTP Basic Authentication One of the simplest options is HTTP Basic Authentication. This is incredibly easy to do in Rails and most API clients should have no problem supporting it. To use it we just need to modify the controller that serves the API with a call to http_basic_authentication_with, passing it a name and a password. /app/controllers/api/v1/products_controller.rb module Api module V1 class ProductsController < ApplicationController http_basic_authenticate_with name: "admin", password: "secret" respond_to :json # Actions omitten end end end In a real application we’d move the name and password into some kind of external configuration so that they aren’t stored in version control. If we need to do this in multiple controllers we could move it into a new controller and then subclass the other controllers from it. We can

If you're comfortable with Rails but new to AngularJS, this tutorial is perfect for you. 1.2 What You'll Learn By the end of this tutorial you should be able to answer the following questions: - How do I create an Angular/Rails single-page application at all? - How do I use Devise with AngularJS? - How do I secure the various pages of my application? - How do I write integration tests for my authentication features? 2 Laying The Groundwork Before it makes sense to start talking about building any authentication features, you'll of course need to spin up a new Rails project and install Angular. I like to structure my Angular/Rails projects as single-page applications and that's the structure I'll be
