I am running this on ruby console to test the file upload api.
HttpClient.post('/storage.xml',:basic_auth=> {:username=>'badde88248834bec759d94563f102d52e19702fa',:password=>'b890b48e2769192372bf531fc46827cd86bea23f'} ,:query => {:auth_token=> '1045aa26cda23f5f3aec737a45e7ba0017c1a7cf',:user_file => File.new( '/home/umair/Login.png')})

I ran into the same problem and couldn't find a solution. Now I'm doing this, it only requires the multipart-post gem.
class Client
require 'net/http/post/multipart'
def self.perform inputurl, file
url = URI.parse(inputurl)
File.open(file) do |transfile|
Net::HTTP.start(url.host, url.port) do |http|
req = Net::HTTP::Post::Multipart.new(
url.path,
file1: UploadIO.new(transfile, "multipart/formdata", File.basename(file)),
)
response = http.request(req)
end
end
end
end
