Overview

Savon::WSDL

Savon::WSDL represents the WSDL of your service, including information like the namespace URI, the SOAP endpoint and available SOAP actions.

The WSDL document

Retrieve the raw WSDL document:

client.wsdl.to_s

Available SOAP actions

Get an array of available SOAP actions:

client.wsdl.soap_actions
# => [:get_all_users, :get_user_by_id]

Namespace URI

Get the namespace URI:

client.wsdl.namespace_uri
# => "http://ws.userservice.example.com"

SOAP endpoint

Get the SOAP endpoint:

client.wsdl.soap_endpoint
# => "http://example.com"

Disable Savon::WSDL

Especially with large services (i.e. Ebay), getting and parsing the WSDL document can really slow down your request. The WSDL is great for exploring a service, but it’s recommended to disable it for production.

When disabling the WSDL, you need to pay attention to certain differences:

  1. You instantiate Savon::Client with the actual SOAP endpoint instead of pointing it to the WSDL of your service.

  2. You also need to manually specify the SOAP.namespace.

  3. Append an exclamation mark (!) to your SOAP call:

client = Savon::Client.new "http://example.com"

client.get_user_by_id! do |soap|
  soap.namespace = "http://example.com/UserService"
  soap.body = { :id => 666 }
end

Without the WSDL, Savon also has to guess the name of the SOAP action and input tag. It takes the name of the method called on its client instance, converts it from snake_case to lowerCamelCase and uses the result.

The example above expects a SOAP action with an original name of “getUserById”. If you service uses UpperCamelCase method names, you can just use the original name:

client.GetAllUsers!

For special cases, you could also specify the SOAP.action and SOAP.input inside the block:

client.get_user_by_id! do |soap|
  soap.namespace = "http://example.com/UserService"
  soap.action = "GetUserById"
  soap.input = "GetUserByIdRequest"
  soap.body = { :id => 123 }
end
