ruby-savon communicate with mono-wcf - ruby

Question

i am new to mono wcf, and i came across some problems about my code.
recent, i use ruby-savon to get data from wcf host on mono.
and this is my ruby code:
client = Savon::Client.new do
wsdl.document="http://localhost:9000/MonoWcf/MonoSevice/wsdl"
end
puts client.wsdl.soap_actions
response = client.request :get_data
and this this puts :

and this is the mono-wcf wsdl :

`
**but when i host wcf in windows(7), it really get the data.
my os is: ubuntu 12

This is a bug in Mono's WCF code that I just fixed in mono/master commit ea2f2cd.
Ruby-savon sends Content-Type: text/xml;charset=UTF-8, but the server expected Content-Type: text/xml; charset=utf-8. This is incorrect, the check is supposed to be case-insensitive and ignore whitespace.
You need to either compile the latest mono from github or, as a temporary workaround, somehow make ruby-savon send Content-Type: text/xml; charset=utf-8.
Temporary Workaround
Edit lib/savon/request.rb (it's in /Library/Ruby/Gems/1.8/gems/savon-2.0.2 on my Mac), at the top, there's
CONTENT_TYPE = {
1 => "text/xml;charset=%s",
2 => "application/soap+xml;charset=%s"
}
Change that into
CONTENT_TYPE = {
1 => "text/xml; charset=%s",
2 => "application/soap+xml; charset=%s"
}
Then set the encoding to "utf-8", for instance:
require 'savon'
client = Savon.client(:wsdl => "http://localhost:9999/MyService?wsdl", :encoding => "utf-8")
puts client.operations
response = client.call(:hello)
Tested with Ruby 1.8.7 on my Mac.
