Overview

Communicates with the CopyTuner server. This class is used to actually download and upload blurbs, as well as issuing deploys.

A client is usually instantiated when CopyTunerClient::Configuration#apply is called, and the application will not need to interact with it directly.

def deploy
  connect(host) do |http|
    response = http.post(uri('deploys'), '', 'User-Agent' => USER_AGENT)
    check response
    log 'Deployed'
  end
end

#download {|Hash| ... } ⇒ Object

Downloads all blurbs for the given api_key.

If the public option was set to true, this will use published blurbs. Otherwise, draft content is fetched.

The client tracks ETags between download requests, and will return without yielding anything if the server returns a not modified response.

Yields:

  • (Hash) —
