Class ActionWebService::Client::Soap
In: actionwebservice/lib/action_web_service/client/soap_client.rb
Parent: Base

Implements SOAP client support (using RPC encoding for the messages).

Example Usage

  class PersonAPI < ActionWebService::API::Base
    api_method :find_all, :returns => [[Person]]
  end

  soap_client = ActionWebService::Client::Soap.new(PersonAPI, "http://...")
  persons = soap_client.find_all

Methods

Attributes

driver  [R]  provides access to the underlying soap driver

Public Class methods

Creates a new web service client using the SOAP RPC protocol.

api must be an ActionWebService::API::Base derivative, and endpoint_uri must point at the relevant URL to which protocol requests will be sent with HTTP POST.

Valid options:

:namespace
If the remote server has used a custom namespace to declare its custom types, you can specify it here. This would be the namespace declared with a [WebService(Namespace = "namespace")] attribute in .NET, for example.
:driver_options
If you want to supply any custom SOAP RPC driver options, you can provide them as a Hash here

The :driver_options option can be used to configure the backend SOAP RPC driver. An example of configuring the SOAP backend to do client-certificate authenticated SSL connections to the server:

  opts = {}
  opts['protocol.http.ssl_config.verify_mode'] = 'OpenSSL::SSL::VERIFY_PEER'
  opts['protocol.http.ssl_config.client_cert'] = client_cert_file_path
  opts['protocol.http.ssl_config.client_key'] = client_key_file_path
  opts['protocol.http.ssl_config.ca_file'] = ca_cert_file_path
  client = ActionWebService::Client::Soap.new(api, 'https://some/service', :driver_options => opts)
