Savon body problem

require "savon"

client = Savon::Client.new "http://www.brenda-enzymes.org/soap2/brenda.wsdl"

response = client.request (:get_km_value) do |soap|
    soap.body = {'ecNumber' => '1.1.1.1'}
end

x = response[:get_km_value_response][:return]
puts x

Gives results {"@xsi:type"=>"xsd:string"}

Expected Result:

"ecNumber*string#kmValue*string#kmValueMaximum*string#substrate*string#commentary*string#organism*开发者_开发问答string#ligandStructureId*string! ecNumber*string#kmValue*string#kmValueMaximum*string#substrate*string#commentary*string#organism*string#ligandStructureId*string! ecNumber*string#kmValue*string#kmValueMaximum*string#substrate*string#commentary*string#organism*string#ligandStructureId*string! ..."

I finally got it working by using the SOAP::Lite Perl library, enabling debug output and executing a sample request from their website.

client = Savon::Client.new "http://www.brenda-enzymes.org/soap2/brenda.wsdl"

response = client.request(:get_km_value) do
  soap.body = {
    "c-gensym3" => "ecNumber*1.1.1.1#organism*Homo sapiens#"
  }
end

puts response[:get_km_value_response][:return]
