Fetch Gists from the API

fetch_gists.rb

require 'net/http'
require 'json'

# a simple wrapper to do an HTTP GET
def fetch_uri(uri)
  Net::HTTP.get_response(URI(uri))
end

# GETs the URI and returns a Ruby hash.
def fetch_json(uri)
  result = fetch_uri(uri)
  JSON.load(result.body)
end

# Gets the next uri via pagination in headers
def next_uri(uri)
  result = fetch_uri(uri)
  links = result.to_hash['link']

  # stupid parsing. We'd use something real here in
  # production
  link_array = links.first.split(",")
  link_array.collect! do |string|
    string =~ /\<(.*)\>; rel="(.*)"/
    [$2, $1]
  end

  Hash[link_array]["next"]
end

# omg hax! I don't want to deal with templates, so
# let's punt on that. You'd use a real URI templates
# parser in real code.
def parse_uri_template(uri)
  uri[0..-11]
end

# Let's begin!

json = fetch_json('https://api.github.com/')

base_uri = parse_uri_template(json["gists_url"])

next_uri = next_uri(base_uri)

json = fetch_json(next_uri)
first_entry = json[0]

puts "DATA:"
puts "ID:\t#{first_entry["id"]}"
puts "URL:\t#{first_entry["url"]}"
puts "USER:\t#{first_entry["user"]["login"]}"

had to modify for https to work

oh? This worked for me, unmodified. weird.

I'm getting 400 The plain HTTP request was sent to HTTPS port with this code on ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-darwin12.2.1]
