Downloads Vines associated with a certain account

vinescrape.rb

# vinescrape.rb goes through an account's Vines and downloads them, skipping revines
# I had to write it because I didn't get notified of the download deadline and
# with no email address on their site, it wouldn't let me get my archive..
# so I came up with this approach instead :-D
#
# To use, just change the VINE_USER_ID string below to the long set of digits that makes up YOUR Vine ID
# Then ruby vinescrape.rb
# Works fine with no dependencies on Ruby 2.4 on OS X, should work fine elsewhere too

VINE_USER_ID = "970482265149054976"
USER_AGENT = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/#{41 + rand(10)}.0.2228.0 Safari/537.36"

require 'open-uri'
require 'json'

# Given a URL, we go GET it
def fetch_data(url)
  open(url, "User-Agent" => USER_AGENT).read
end

page = 1

# First, we need to fetch the first 'page' of results
url = "https://vine.co/api/timelines/users/#{VINE_USER_ID}?page=#{page}"
data = JSON.parse(fetch_data(url))
total_vines = data['data']['count'].to_i

STDERR.puts "#{total_vines} vines to fetch"
sleep 1
i = 0
downloaded = 0

loop do
  url = "https://vine.co/api/timelines/users/#{VINE_USER_ID}?page=#{page}"
  STDERR.puts "Fetching page #{page} of vines"
  data = JSON.parse(fetch_data(url))

  vines = data['data']['records']

  vines.each do |vine|
    i += 1

    STDERR.puts "Processing #{i}/#{total_vines}"

    # Skip "revines"
    unless vine['userId'].to_s == VINE_USER_ID
      STDERR.puts "  Revine - not downloading"
      next
    end

    # Get the URL of the MP4 video
    url = vine['videoDashUrl']

    # Download and save the video locally
    STDERR.puts "  Downloading #{url}"
    begin
      File.open("#{vine['postId']}.mp4", "w") { |f| f.puts fetch_data(url) }
      STDERR.puts "  Downloaded!"
      downloaded += 1

      # Sleep a bit to not look too heavy on the server
      sleep rand(3) + 1
    rescue
      STDERR.puts "  Download FAILED"
    end
  end

  break if i >= total_vines
  page += 1
  sleep rand(2) + 1
end

STDERR.puts "#{i} vines processed, #{downloaded} vines downloaded"

And yes the code is a mess. I looked at how Vine's private API worked and threw it together in 20 minutes before they stopped me being able to download my Vines. If it breaks for you or if Vine blocks it, sorry!
