How to send a file via XML RPC

Ruby
1

Does anyone have some sample code showing how to send a file via XML
RPC?

Sending string values is easy … like the below example…

server = XMLRPC::Client.new2(“http://rpc.technorati.com/rpc/ping”)
result = server.call(“weblogUpdates.ping”, “Copenhagen.rb”,
"http://www.copenhagenrb.dk/

… but how would one send a file?

I can’t remember where I first saw this.

$ cat client.rb
#!/usr/bin/ruby

require ‘xmlrpc/client’
require ‘base64’

data = IO.read(’/tmp/test.jpg’)
encoded_file = Base64.encode64(data)

server = XMLRPC::Client.new3({‘host’=>‘localhost’, ‘port’=>8888,
‘timeout’=>30})

if server.call(“put_file”, encoded_file)
puts “ok”
end
puts result

$ cat server.rb
#!/usr/bin/ruby

$SAFE = 1

require “xmlrpc/server”
require ‘base64’

s = XMLRPC::Server.new(8888)
s.add_handler(“put_file”) { |encoded_file|
Dir.chdir(’/tmp/test’)
File.open(‘test.jpg’, ‘w+’) { |file|
file.puts( Base64.decode64(encoded_file) )
}
true
}

s.serve

bingo! … … just needed to encode the binary data into base64
before sending it (and do the reverse at the server end).
