The Road goes ever on and on

 1. 获取Request Token
 2. 用户确认授权
 3. 换取Access Token
 4. 访问受限资源

require 'rubygems'     
gem 'oauth','0.4.3'
require 'oauth'
 
 
API_KEY = "1860579545"
API_KEY_SECRET = "d62c11d9ddaa25d55fc59b1835e73619"
SITE = "http://api.t.sina.com.cn"
 
# 1. 获取Request Token
consumer = OAuth::Consumer.new(API_KEY, API_KEY_SECRET, { :site => SITE })
request_token = consumer.get_request_token
puts request_token.inspect
 
# 2. 用户确认授权
callback_url = "http://localhost.com/oauth"
url = "#{request_token.authorize_url}&oauth_token_secret=#{request_token.secret}&oauth_callback=#{callback_url}"
puts "请将下面url粘贴到浏览器中，并同意授权，同意后按任意键继续:\n#{url}"
# response = Net::HTTP.get(URI.parse(url))
# puts response.body
 
 
sleep(30) # 将回调url里的oauth_verifier手动存到本地
 
# 3. 通过授权码oauth_verfier换取access_token
oauth_verifier = IO.readlines("verifier.txt").first.strip
verify_hash = {:oauth_verifier => oauth_verifier}
access_token = request_token.get_access_token(verify_hash)
 
# access_token = OAuth::AccessToken.new(consumer, access_token.token, access_token.secret)
# puts access_token.inspect                                      
 
# 4. 通过access_token访问受限资源(API)
response = access_token.get "/statuses/home_timeline.xml"
puts response.body
