module OAuth2
Overview
The OAuth module provides an OAuth2::Client
as specified
by RFC6749.
Performing HTTP client requests with OAuth2 authentication
Assuming you have an access token, you can setup an HTTP::Client
to be authenticated with OAuth2 using this code:
require "http/client"
require "oauth2"
# Here we use a bearer token, but it could be a mac token
access_token = OAuth2::AccessToken::Bearer.new("some_access_token")
# Create an HTTP::Client
client = HTTP::Client.new("api.example.com", tls: true)
# Prepare it for using OAuth2 authentication
access_token.authenticate(client)
# Execute requests as usual: they will be authenticated
client.get("/some_path")
This is implemented with HTTP::Client#before_request
to add an authorization
header to every request.
Obtaining access tokens
See OAuth2::Client
for an example.
