A Ruby library for interaction with the Tropo Web API (tropo.com) using JSON.
The Tropo Remote API provides a RESTful JSON API for controlling realtime communications applications from your own web servers.
-
Unit tests passed on: Ruby MRI v1.8.6/1.8.7 and JRuby v1.5.0
-
RubyGems
Note: If using with ActiveSupport, v2.3.5 or better of ActiveSupport is required.
$ sudo gem install tropo-webapi-ruby
Optional, if you would like to use with Sinatra:
$ sudo gem install sinatra
$ gemserver
$ sudo gem install yard
From within the project:
$ yardoc
require 'rubygems' require 'tropo-webapi-ruby' # Will return the properly formatted JSON to pass to Tropo response = Tropo::Generator.ask({ :say => 'Hello world!' }) # Will return a Ruby Hash, with some transformations, from the JSON string received from Tropo response = Tropo::Generator.parse(json_string) # Will provide instance variables that will allow you to easily reference session type tropo = Tropo::Generator.new response = tropo.parse(json_string) p 'Hey, this is a voice session!' if tropo.voice_session p 'Hey, this is a text messaging session!' if tropo.text_session
Using the great RESTful Web Services framework Sinatra for Ruby.

In order to maintain compatibility between Ruby MRI and JRuby the gem requires ‘json_pure’. If you are using the Ruby MRI and would prefer to use the C version of ‘json’, simply install the ‘json’ gem as follows:
sudo gem install json
