Overview

This module’s static methods are the entry point for using the REST client.

# GET
xml = RestClient.get 'http://example.com/resource'
jpg = RestClient.get 'http://example.com/resource', :accept => 'image/jpg'

# authentication and SSL
RestClient.get 'https://user:[email protected]/private/resource'

# POST or PUT with a hash sends parameters as a urlencoded form body
RestClient.post 'http://example.com/resource', :param1 => 'one'

# nest hash parameters
RestClient.post 'http://example.com/resource', :nested => { :param1 => 'one' }

# POST and PUT with raw payloads
RestClient.post 'http://example.com/resource', 'the post body', :content_type => 'text/plain'
RestClient.post 'http://example.com/resource.xml', xml_doc
RestClient.put 'http://example.com/resource.pdf', File.read('my.pdf'), :content_type => 'application/pdf'

# DELETE
RestClient.delete 'http://example.com/resource'

# retreive the response http code and headers
res = RestClient.get 'http://example.com/some.jpg'
res.code                    # => 200
res.headers[:content_type]  # => 'image/jpg'

# HEAD
RestClient.head('http://example.com').headers

To use with a proxy, just set RestClient.proxy to the proper http proxy:

RestClient.proxy = "http://proxy.example.com/"

Or inherit the proxy from the environment:

RestClient.proxy = ENV['http_proxy']

For live tests of RestClient, try using rest-test.heroku.com, which echoes back information about the rest call:

>> RestClient.put 'http://rest-test.heroku.com/resource', :foo => 'baz'
=> "PUT http://rest-test.heroku.com/resource with a 7 byte payload, content type application/x-www-form-urlencoded {\"foo\"=>\"baz\"}"
