Overview

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

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

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

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

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

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

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

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

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

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

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

Or inherit the proxy from the environment:

HttpClient.proxy = ENV['http_proxy']

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

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