Script for mass uploading images to Facebook test users profiles.

go.rb

# This script gets test users' access tokens, and
# uploads public images to those accounts

# At the time of this writing, it takes an input file ( of facebook UIDs )
# an queries an external JSON file for those users ( filtering ). The remaining
# filtered users will have images uploaded to their profiles, via the graph
# api. 

require "json";
require "rest-client"

# =======================
# ==== Configuration ====
# =======================
graph_api    	= "https://graph.facebook.com/"

# Your apps access token. This is used to retrieve test
# users' access tokens.
access_token 	= "<APP_ACCESS_TOKEN>"

# Folder containing images to be uploaded
image_bucket 	= "/Users/eric.tuchscherer/headshots/"

# The input file is a json list of test user objects.
# Users are under the "data" key. 
#
# Example:
# {
#    "data": [
#       {
#          "id": "123456789",
#          "access_token": "a;sdlkfjdsdsfasdf...",
#          "login_url": "http://developers.facebook.com/checkpoint/test-user-login/123456789/"
#       },
#       {
#          "id": "987654321",
#          "access_token": "sadjhkfgasdoaisud...",
#          "login_url": "http://developers.facebook.com/checkpoint/test-user-login/987654321/"
#       }... ect
#
input_file   	= "/Users/eric.tuchscherer/json.js"

# The filter file is a list of test user ids. This is used to
# remove unwanted test users from the filtered list
#
# Example:
# 123456789
# 987654321
# ect
filter_file  	= "/Users/eric.tuchscherer/filters"

# =======================
# ======== begin ========
# =======================
# Load all users' JSON data
all_test_users 	= JSON.parse(IO.read(input_file))

# Using these ids only
working_ids  	= IO.readlines(filter_file).map { |l| l.chomp }

# The actual list of users to work with
working_list	= all_test_users["data"]

# filter working_list array
filtered_data = working_list.keep_if { |x| filters.include? x["id"] }

# generate urls to upload photos.
filtered_data.each do |d|

	url = "#{graph_api}#{d["id"]}/photos?access_token=#{d["access_token"]}"
	random_image = "#{image_bucket}/a#{rand(2..261)}.jpg"

	RestClient.post(url, { image: File.new(random_image, 'rb') }) do |res, req, ret, &block|
		puts res + "\n"
	end
end

Hey Eric... if you ever get time, mix in Thor, and package this as a gem.
