With the NET/HTTP library, you can get the content of a distant file.
Then with the JSON library you can parse a json string into a hash.

def get_datas
    url = URI.parse("http://www.example.com/page.json")
    res = Net::HTTP.start(url.host, url.port) {|http|
        http.get(url.path)
    }
    JSON.parse res.body
end
