Sinatra::Soap — Not maintained.

Sinatra-soap gem makes task to create SOAP API really simple. Inspired by WashOut gem for Rails. But remember, the only reason why you should use SOAP is legacy code.

In case of simplicity and quick first working release:

A classic application would work like that:

require 'sinatra'
require 'sinatra/soap'

soap "SomeAction" do
  do_something_with_params # hash to be returned
end

A modular application would look like that:

require 'sinatra/base'
require 'sinatra/soap'

class SoapAPI < Sinatra::Base

  #remember to register extenstion if you are using modular style
  register Sinatra::Soap 

  soap "SomeAction" do
    params # hash to be returned
  end
end

• :wsdl_route — url for getting wsdl, either static or dynamically generated file

set :wsdl_route, '/wsdl'

Defines route for app to response with wsdl. Default is '/wsdl'

• :endpoint — url for sending SOAP Requests

set :endpoint, '/action'

Defines route for SOAP Requests. Default is '/action'

• :wsdl_file — app will send static file, if this setting specified

set :wsdl_file, "wsdl.xml"

If wsdl_file is set, app will try to read wsdl file from :public_folder (by default ./public directory). If file does not exist, app will raise an error. You also don't need to specify :namespace or :service if you want to serve static wsdl.

• :namespace — wsdl setting, required for generating wsdl

set :namespace, "http://schemas.xmlsoap.org/wsdl/"

Namespace is taking it's place in xmlns:tns and targetNamespace definitions of SOAP Envelope

• :service — wsdl setting, required for generating wsdl

set :service, "sinatra"

Service involved in portType, binding and service definitions as a prefix for name attribute.

If you want to be able to generate wsdl on a fly, you need to specify incoming and outgoing nodes with their types.

soap :test, in: {circle: {center: {x: :integer, 
                                   y: :integer}, 
                          radius: :double}
                },
            out: nil do
  params #=> {circle: {center: {x: 3, y: 2}, radius: 12.0} }
  nil
end

The code above will respond to request like this:

<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:wsdl="anynamespacehere" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
  <env:Body>
    <wsdl:test>
      <circle>
        <center>
          <x>3</x>
          <y>2</y>
        </center>
        <radius>12.0</radius>
      </circle>
    </wsdl:test>
  </env:Body>
</env:Envelope>
