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.strip
puts "Enter the consumer secret you are assigned:"
auth["consumer_secret"] = gets.strip
puts "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_url
puts "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.token
auth["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

 

#!/usr/bin/ruby
 
# Simple OSM Auth example showing GET PUT and DELETE methods
# Requires OAuth rubygem
 
require 'rubygems'
require 'oauth'
require 'date'
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 = YAML.load(File.open('auth.yaml'))
 
# The consumer key and consumer secret are the identifiers for this particular application, and are 
# issued when the application is registered with the site. 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

 

#!/usr/bin/ruby
 
# hacky script for uploading a file to the OSM GPX api. 
# liberally stolen^Winspired by http://gist.github.com/97756
#
# 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)
 
require 'rubygems'
require 'oauth'
require 'xml/libxml'
require 'date'
 
CRLF = "\r\n"
endpoint_gpx_create = 'http://api06.dev.openstreetmap.org/api/0.6/gpx/create'
 
if ARGV.size < 1
  puts "Usage: #{$0} path_to_gpx_file"
  puts "e.g. #{$0} /home/gravitystorm/osm/tracks/20081128.gpx"
  exit(1)
end
 
# Take GPX file from commandline argument
file = File.new(ARGV[0])
 
# 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 = YAML.load(File.open('auth.yaml'))
 
@consumer=OAuth::Consumer.new auth['consumer_key'], 
                              auth['consumer_secret'], 
                              {:site=>"http://api06.dev.openstreetmap.org"}
 
@access_token = OAuth::AccessToken.new(@consumer, auth['token'], auth['token_secret']) 
 
# Encodes the request as multipart
def add_multipart_data(req,params)
  boundary = Time.now.to_i.to_s(16)
  req["Content-Type"] = "multipart/form-data; boundary=#{boundary}"
  body = ""
  params.each do |key,value|
    esc_key = CGI.escape(key.to_s)
    body << "--#{boundary}#{CRLF}"
    if value.respond_to?(:read)
      body << "Content-Disposition: form-data; name=\"#{esc_key}\"; filename=\"#{File.basename(value.path)}\"#{CRLF}"
      body << "Content-Type: text/xml#{CRLF*2}"
      body << value.read
    else
      body << "Content-Disposition: form-data; name=\"#{esc_key}\"#{CRLF*2}#{value}"
    end
    body << CRLF
  end
  body << "--#{boundary}--#{CRLF*2}"
  req.body = body
  req["Content-Length"] = req.body.size
end
 
# Uses the OAuth gem to add the signed Authorization header
def add_oauth(req)
  @consumer.sign!(req,@access_token)
end
 
#Actually do the request and print out the response
url = URI.parse(endpoint_gpx_create)
Net::HTTP.new(url.host, url.port).start do |http|
  req = Net::HTTP::Post.new(url.request_uri)
  add_multipart_data(req,:file=>file, :tags=>'heheheheh', :description=>'upside down', :public=>'1')
  add_oauth(req)
  res = http.request(req)
  puts res.body
end
