Content-Transfer-Encoding: 7bit

I am trying to upload a file to API thr the 'net/http' or 'rest-open-uri'  
client,
the code I have done is
require 'rest-open-uri'
require 'uri'
require 'cgi'
require 'net/http'
require 'net/https'
require 'mime/types'


username="XXXXXXXXXXXXXXXXXXXXXXX"
password="XXXXXXXXXXXXXXXXXXXXXX"

def form_encoded(hash)
encoded = []
hash.each do |key, value|
encoded << CGI.escape(key) + '=' + CGI.escape(value)
end
return encoded.join('&')
end
boundary_token = [Array.new(8) {rand(256)}].join
boundary_marker = "--#{boundary_token}\r\n"
file = File.open("my_img.jpg")
filename = File.basename(file.path)
mime_type = MIME::Types.of(filename)
@service_root = "#######################"
representation =  
form_encoded({ "Content-Type"=>"#{mime_type}\r\n\r\n#{file.read}\r\n","Content-Transfer-Encoding"  
=> "binary\r\n", "Content-Disposition"  
=> "form-data" , "uploaded_data[filename]"=>"#{filename}"})
puts representation
response = open(@service_root + '/file/uploads.xml', :method  
=> :post,:http_basic_authentication => [username,  
password],:body=>representation )

puts response.read
The error I am getting is...

I am not really sure about the way to be done!
