OAuth

Simple OAuth and OAuth2 API for Luvit.io. It allows users to authenticate against providers and thus act as OAuth consumers. Tested against Twitter (http://twitter.com) and Github (http://github.com).

Install

Since version 1.0.0 Utopia uses lit as dependency manager:

lit install voronianski/oauth

Examples

To run examples clone this repo, create your applications on Twitter (for OAuth example) and Github (for OAuth2), paste necessary keys and secrets into files and execute them like luvit example/oauth.lua:

OAuth1.0

local OAuth = require('luvit-oauth').OAuth

local oauth = OAuth:new({
	requestUrl = 'https://api.twitter.com/oauth/request_token',
	accessUrl = 'https://api.twitter.com/oauth/access_token',
	consumerKey = '{{YOUR CONSUMER KEY}}',
	consumerSecret = '{{YOUR CONSUMER SECRET}}'
})

oauth:getOAuthRequestToken(function (err, requestToken, requestTokenSecret)
	p(err, requestToken, requestTokenSecret)

	-- use your flow for verification
	oauth:getOAuthAccessToken(requestToken, requestTokenSecret, '{{YOUR OAUTH VERIFIER}}', function (err, accessToken, accessTokenSecret)
		p(err, accessToken, accessTokenSecret)
	end)
end)

and luvit example/oauth2.lua:

OAuth2.0

local OAuth2 = require('luvit-oauth').OAuth2

local oauth2 = OAuth2:new({
	clientID = '{{YOUR CLIENT ID}}',
	clientSecret = '{{YOUR CLIENT SECRET}}',
	baseSite = 'https://github.com/login'
})

local opts = {redirect_uri = 'http://luvit.io/oauth'}

-- go to received URL and copy code
local authURL = oauth2:getAuthorizeUrl(opts)

oauth2:getOAuthAccessToken('{{YOUR CODE}}', opts, function (err, access_token, refresh_token, results)
	p(err, access_token, refresh_token, results)
end)

API

OAuth1.0

Initialize

:new(options)

Create instance of OAuth class by calling :new(options) with options table as the only argument.

Options

• requestUrl - required request token url
• accessUrl - required oauth token url
• consumer_key - required public key
• consumer_secret - required private key
• signature_method - allowed by spec signing crypto method. It could be 'HMAC-SHA1' (default), 'PLAINTEXT' or 'RSA-SHA1'
• authorize_callback - optional authorization callback url, defaults to nil
• nonce_size - size of unique token your application will generate for each unique request, default 32
• version - spec version, defaults to 1.0
• customHeaders - optional table with http headers to be sent in the requests

:setClientOptions(options)

Change things like http methods for request token and access token urls.

Options

• requestTokenHttpMethod - default 'POST'
• accessTokenHttpMethod - default 'POST'
• followRedirects - default true

:getOAuthRequestToken(extraParams, callback)

Requests an unauthorized request token (http://tools.ietf.org/html/rfc5849#section-2.1). extraParams is an optional table value which will be sent as querystring or as application/x-www-form-urlencoded for POST body.

:getOAuthAccessToken(requestToken, requestTokenSecret, oauthVerifier, callback)

Exchanges a request token for an access token (http://tools.ietf.org/html/rfc5849#section-2.3).

:request(url, options, callback)

Allows to make OAuth signed requests to provided API url string.

Options

• method - http method that will be send, required (not necessary with shorteners)
• oauth_token - required access token
• oauth_token_secret - required access token secret
• post_body - body that will be sent with POST or PUT
• post_content_type - content type for POST or PUT requests, default application/x-www-form-urlencoded
• extraParams - optional table with values that will be sent as querystring or post_body for POST requests if it's not provided

OAuth 2.0

Initialize

:new(options)

Create instance of OAuth2 class by calling :new(options) with options table as the only argument.

Options

• clientID - required client id
• clientSecret - required client secret
• baseSite - required base OAuth provider url
• authorizePath - optional, default '/oauth/authorize'
• accessTokenPath - optional, default '/oauth/access_token'
• customHeaders - optional table with http headers to be sent in the requests

:setAccessTokenName(name)

Change access_token param name to different one if authorization server waits for another.

:setAuthMethod(method)

Change authorization method that defaults to Bearer.

:setUseAuthorizationHeaderForGET(useIt)

If you use the OAuth2 exposed :get() shortener method this will specify whether to use an 'Authorization' header instead of passing the access_token as a query parameter.

:getAuthorizeUrl(params)

Get an authorization url to proceed flow and receive code that will be used for getting access_token.

:getOAuthAccessToken(code, params, callback)

Get an access token from the authorization server.

:request(url, opts, callback)

Allows to make OAuth2 signed requests to provided API url string.

Options

• method - http method that will be send, required (not necessary with shorteners)
• access_token - required access token
• post_body - body that will be sent with POST or PUT
• post_content_type - content type for POST or PUT requests, default application/x-www-form-urlencoded
• headers - optional table with values that will be sent with request

Shorteners

These methods allow to skip method field in request options for both OAuth and OAuth2 implementations:

• :get(url, options, callback)
• :post(url, options, callback)
• :put(url, options, callback)
• :patch(url, options, callback)
• :delete(url, options, callback)
