Instagramをいい感じに

instagram.rb

require 'pp'
require 'watir-webdriver'

directory = File.dirname($0)
config = YAML.load_file(directory + "/config.yml")

USERNAME = ARGV.shift

def instagram(username, password)
  browser = Watir::Browser.new :phantomjs
  browser.goto("https://www.instagram.com/")
  browser.text_field(:name, "username").wait_until_present
  browser.text_field(:name, "password").wait_until_present
  browser.text_field(:name, "username").value = username
  browser.text_field(:name, "password").value = password
  browser.button(:text, /ログイン/).click
  browser.button(:text, /ログイン/).wait_while_present
  yield browser
  browser.close
end

instagram(config["username"], config["password"]) {|insta|
  insta.goto("https://www.instagram.com/#{USERNAME}/")
  insta.div(:class, 'l68').div(:class, 'm68').wait_until_present
  shared_data = insta.execute_script("return _sharedData")
  nodes = shared_data["entry_data"]["ProfilePage"][0]["user"]["media"]["nodes"]
  next_href = $1 if insta.html =~ /max_id=(\d+)/

  pp nodes, next_href
}
