oauth GEM的几个小例子
1、注册并认证你的应用
?
#!/usr/bin/ruby # Get all the auth details you need# You wouldn't actually do it this way, but hey.# Normally you'd distribute the consumer stuff with your# application, and each user gets the access_token stuff# But hey, this is just a demo. require 'rubygems'require 'oauth'require 'yaml' # Format of auth.yml:# consumer_key: (from osm.org)# consumer_secret: (from osm.org)# token: (use oauth setup flow to get this)# token_secret: (use oauth setup flow to get this)auth={} puts "First, go register a new application at "puts "http://api06.dev.openstreetmap.org/oauth_clients/new"puts "Tick the appropriate boxes"puts "Enter the consumer key you are assigned:"auth["consumer_key"] = gets.stripputs "Enter the consumer secret you are assigned:"auth["consumer_secret"] = gets.stripputs "Your application is now set up, but you need to register"puts "this instance of it with your user account." @consumer=OAuth::Consumer.new auth["consumer_key"], auth["consumer_secret"], {:site=>"http://api06.dev.openstreetmap.org"} @request_token = @consumer.get_request_token puts "Visit the following URL, log in if you need to, and authorize the app"puts @request_token.authorize_urlputs "When you've authorized that token, enter the verifier code you are assigned:"verifier = gets.strip puts "Converting request token into access token..." @access_token=@request_token.get_access_token(:oauth_verifier => verifier) auth["token"] = @access_token.tokenauth["token_secret"] = @access_token.secret File.open('auth.yaml', 'w') {|f| YAML.dump(auth, f)} puts "Done. Have a look at auth.yaml to see what's there."??
2、创建简单的HTTP请求

Use your own.@consumer=OAuth::Consumer.new auth['consumer_key'], auth['consumer_secret'], {:site=>"http://api06.dev.openstreetmap.org"} # Create the access_token for all traffic@access_token = OAuth::AccessToken.new(@consumer, auth['token'], auth['token_secret']) # Use the access token for various commands. Although these take plain strings, other API methods # will take XML documents.@access_token.put('/api/0.6/user/preferences/demo_last_run_time', DateTime.now().to_s, {'Content-Type' => 'text/plain' })@access_token.put('/api/0.6/user/preferences/deleteme', "This shouldn't be seen", {'Content-Type' => 'text/plain' })@access_token.delete('/api/0.6/user/preferences/deleteme')puts @access_token.get('/api/0.6/user/preferences').body?3、表单上传文件
