Sending raw XML using Savon 2

问题

I'm trying to use Savon to send requests to a webservice. The service I'm consuming requires nested namespaces, and I haven't figured out yet how to provide them on a request.

I've tried to craft the request by hand (with nokogiri, actually) and send the resulting xml:

client.call(:some_op, :message=>{:"op"=>"<elem/>"})

But savon escapes the string and sends <elem/>

How can I send raw xml without escaping?

回答1:

The call should look like this:

client.call(:some_op, xml: "<elem />")

Or if you just want to set one or multiple namespaces then create a client as follows (without WSDL):

client = Savon.client(
  :endpoint => 'http://www.example.com',
  :namespace => 'urn:core.example.com',
  :namespaces => { 'ns1' => 'http://v1.example.com',
                   'ns2' => 'http://v2.example.com' },
  :log => true,
  :log_level => :debug,
  :pretty_print_xml => true
)

The namespaces are a Hash parameter.

回答2:

It looks like Savon internally uses the Gyoku Gem to convert ruby hashes to XML, and Gyoku will not escape hash keys ending with exclamation marks according to the documentation: https://github.com/savonrb/gyoku#special-characters

So this code works to get raw XML into the request while still using Savon to generate the envelope xml:

client.call(:some_op, :message=>{:"op!"=>"<elem/>"})
