How to read content of remote file in Ruby on Rails?

Question

here my file: http://example.com/test.txt

i have to read content of http://example.com/test.txt (a JSON string) and parse it in Ruby

Answer 1

I would suggest using open-uri:

require 'json'
require 'open-uri'
result = JSON.parse open('http://example.com/data.json').read

Answer 2

require 'net/http'
uri = URI('http://my.json.emitter/some/action')
json = Net::HTTP.get(uri)

json will contain the JSON string you fetched from uri.
