#initialize(url, options) {|builder| ... } ⇒ Connection

Create a new PSC connection. This is a Faraday::Connection with the following middleware:

  • Either Faraday::HttpBasic or Faraday::PscToken depending on the contents of the :authenticator option
  • Faraday::StringIsXml
  • ::Faraday::Request::JSON
  • ::Faraday::Request::UrlEncoded
  • ::FaradayStack::ResponseXML for content-type text/xml
  • ::FaradayStack::ResponseJSON for content-type application/json
  • ::Faraday::Adapter::NetHttp

If a block is provided, it will receive the Faraday builder so that you can append more middleware. If you provide your own adapter, the net/http adapter will not be appended.

Parameters:

  • url (String) —

    the base URL for your PSC instance

  • options (Hash) —

    the options for the connection. These are same as accepted by Faraday::Connection, plus:

Options Hash (options):

  • :authenticator (Hash) —

    parameters for the authentication middleware. These are detailed in the README.

Yields:

  • (builder) —

    (optional)
