Pulling avatars from twitter in a Rails App
Monday, January 19th, 2009Something which may be of use to all bloggers and social app builders is that it is pretty easy to pull someones twitter profile photo in RoR heres the code :
# call the twitter api
url = 'http://twitter.com/users/show/show.xml?email='+CGI.escape(test@test.test)
# get the XML data as a string
xml_data = Net::HTTP.get_response(URI.parse(url)).body
# extract profile image tag information
doc = REXML::Document.new(xml_data)
profile_image = nil
doc.elements.each('user/profile_image_url') do |ele|
profile_image = ele.text
end
# if we have an image and its not a default avatar then continue
if profile_image and ! profile_image.include? "static.twitter.com"
begin
profile_image=profile_image.gsub("_normal","_bigger")
filename="/tmp/"+rand(100000).to_s+File.extname(profile_image).downcase
file=open(filename,"w")
file.write(open(profile_image).read)
file.close
# do as you will with the avatar
rescue
#fail
end
else
#fail
end
