More Info

Examples

Getting started

gem install resourceful

Simplest example

require 'resourceful'
resp = Resourceful.get('http://rubyforge.org')
puts resp.body

Get a page requiring HTTP Authentication

my_realm_authenticator = Resourceful::BasicAuthenticator.new('My Realm', 'admin', 'secret')
http = Resourceful::HttpAccessor.new(:authenticator => my_realm_authenticator)
resp = http.resource('http://example.com/').get
puts resp.body

Redirection based on callback results

Resourceful will by default follow redirects on read requests (GET and HEAD), but not for POST, etc. If you want to follow a redirect after a post, you will need to set the resource#on_redirect callback. If the callback evaluates to true, it will follow the redirect.

resource = http.resource('http://example.com/redirect_me')
resource.on_redirect { |req, resp| resp.header['Location'] =~ /example.com/ }
resource.get  # Will only follow the redirect if the new location is example.com

Post a URL encoded form

 require 'resourceful'
 http = Resourceful::HttpAccessor.new
 resp = http.resource('http://mysite.example/service').
          post(Resourceful::UrlencodedFormData.new(:hostname => 'test', :level => 'super'))

Post a Mulitpart form with a file

 require 'resourceful'
 http = Resourceful::HttpAccessor.new
 form_data = Resourceful::MultipartFormData.new(:username => 'me')
 form_data.add_file('avatar', '/tmp/my_avatar.png', 'image/png')
 resp = http.resource('http://mysite.example/service').post(form_data)

Put an XML document

 require 'resourceful'
 http = Resourceful::HttpAccessor.new
 resp = http.resource('http://mysite.example/service').
          put('<?xml version="1.0"?><test/>', :content_type => 'application/xml')

Delete a resource

 require 'resourceful'
 http = Resourceful::HttpAccessor.new
 resp = http.resource('http://mysite.example/service').delete
