class Puppet::Util::Puppetdb::Http
Constants
- SERVER_URL_FAIL_MSG
Public Class Methods
Setup an http connection, provide a block that will do something with that http connection. The block should be a two argument block, accepting the connection (which you can call get or post on for example) and the properly constructed path, which will be the concatenated version of any url_prefix and the path passed in.
@param path_suffix [String] path for the get/post of the http action @param http_callback [Proc] proc containing the code calling the action on the http connection @return [Response] returns http response
