从url中获取json对象，同时在rails上的ruby中使用facebook graph api

Question

how to get the JSON object through URL in my ruby on rails code:

url = "https://graph.facebook.com/me/friends?access_token=XXX"

I am not able to get good tutorial for JSON + Ruby on rails. Can someone help me out thanks.

Answer 1

require 'open-uri'
require 'json'

json_object = JSON.parse(open("https://graph.facebook.com/me/friends?access_token=XXX").read)

This is the simplest way, though it may not be the fastest.

Edit: If the URI contains special characters in its parameter string, it has to be escaped/encoded with URI.escape first.
