REST Client – simple DSL for accessing REST resources¶ ↑

A simple REST client for Ruby, inspired by the Sinatra’s microframework style of specifying actions: get, put, post, delete.

Usage: Raw URL¶ ↑

require 'rest_client'

RestClient.get 'http://example.com/resource'
RestClient.get 'https://user:[email protected]/private/resource'

RestClient.post 'http://example.com/resource', :param1 => 'one', :nested => { :param2 => 'two' }

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

See RestClient module docs for details.

Usage: ActiveResource-Style¶ ↑

resource = RestClient::Resource.new 'http://example.com/resource'
resource.get

private_resource = RestClient::Resource.new 'https://example.com/private/resource', :user => 'adam', :password => 'secret', :timeout => 20, :open_timeout => 5
private_resource.put File.read('pic.jpg'), :content_type => 'image/jpg'

See RestClient::Resource module docs for details.

Usage: Resource Nesting¶ ↑

site = RestClient::Resource.new('http://example.com')
site['posts/1/comments'].post 'Good article.', :content_type => 'text/plain'

See RestClient::Resource docs for details.

Shell¶ ↑

The restclient shell command gives an IRB session with RestClient already loaded:

$ restclient
>> RestClient.get 'http://example.com'

Specify a URL argument for get/post/put/delete on that resource:

$ restclient http://example.com
>> put '/resource', 'data'

Add a user and password for authenticated resources:

$ restclient https://example.com user pass
>> delete '/private/resource'

Create ~/.restclient for named sessions:

sinatra:
  url: http://localhost:4567
rack:
  url: http://localhost:9292
private_site:
  url: http://example.com
  username: user
  password: pass

Then invoke:

$ restclient private_site

Use as a one-off, curl-style:

$ restclient get http://example.com/resource > output_body

$ restclient put http://example.com/resource < input_body

Logging¶ ↑

Write calls to a log filename (can also be “stdout” or “stderr”):

RestClient.log = '/tmp/restclient.log'

Or set an environment variable to avoid modifying the code:

$ RESTCLIENT_LOG=stdout path/to/my/program

Either produces logs like this:

RestClient.get "http://some/resource"
# => 200 OK | text/html 250 bytes
RestClient.put "http://some/resource", "payload"
# => 401 Unauthorized | application/xml 340 bytes

Note that these logs are valid Ruby, so you can paste them into the restclient shell or a script to replay your sequence of rest calls.

Proxy¶ ↑

All calls to RestClient, including Resources, will use the proxy specified by RestClient.proxy:

RestClient.proxy = "http://proxy.example.com/"
RestClient.get "http://some/resource"
# => response from some/resource as proxied through proxy.example.com

Often the proxy url is set in an environment variable, so you can do this to use whatever proxy the system is configured to use:

RestClient.proxy = ENV['http_proxy']

Cookies¶ ↑

Request and Response objects know about HTTP cookies, and will automatically extract and set headers for them as needed:

response = RestClient.get 'http://example.com/action_which_sets_session_id'
response.cookies
# => {"_applicatioN_session_id" => "1234"}

response2 = RestClient.post(
  'http://localhost:3000/',
  {:param1 => "foo"},
  {:cookies => {:session_id => "1234"}}
)
# ...response body
