Installation

Savon is available through Rubygems and can be installed via:

$ gem install savon

or add it to your Gemfile like this:

gem 'savon', '~> 3.0.0'

Usage example

require 'savon'

# create a client for the service
client = Savon.client(wsdl: 'http://service.example.com?wsdl')

# or: create a client with a wsdl provided as a string
client = Savon.client do |config|
  wsdl_content = File.read("/path/to/wsdl")
  config.wsdl wsdl_content
end

client.operations
# => [:find_user, :list_users]

# call the 'findUser' operation
response = client.call(:find_user, message: { id: 42 })

response.body
# => { find_user_response: { id: 42, name: 'Hoff' } }

For more examples, you should check out the integration tests.

FAQ

• URI::InvalidURIError -- if you see this error, then it is likely that the http client you are using cannot parse the URI for your WSDL. Try gem install httpclient or add it to your Gemfile.
