| == Simple Ruby script ==
| |
| Here is a very simple Ruby script to get you subscribing to messages, they simply get output to the console.
| |
| You'll obviously need Ruby installed (I'm using 1.9.3 via RVM) and the stomp ruby gem installed <code>gem install stomp</code>
| |
| | |
| You will of course, also need to have signed up to the Network Rail datafeed programme and have your login credentials.
| |
| Then set up environment variables with DATAFEEDS_USER as your username and DATAFEEDS_PASSWORD as your password.
| |
| | |
| <code>
| |
| require 'stomp'
| |
|
| |
| begin
| |
| # Credentials set here as environment variables
| |
| @user = ENV["DATAFEEDS_USER"];
| |
| @password = ENV["DATAFEEDS_PASSWORD"]
| |
| @host = "datafeeds.networkrail.co.uk"
| |
| @port = 61618
| |
|
| |
| # Example destination add yours here
| |
| @destination = "/topic/TD_ALL_SIG_AREA"
| |
|
| |
| puts "Connecting to datafeeds as #{@user} using stomp protocol stomp://#{@host}:#{@port}\n"
| |
| @connection = Stomp::Connection.open @user, @password, @host, @port, true
| |
| @connection.subscribe @destination
| |
|
| |
| while true
| |
| @msg = @connection.receive
| |
| puts @msg
| |
| end
| |
| @connection.disconnect
| |
| rescue
| |
| end
| |
| </code>
