A library for dealing with SOAP requests and responses. We tear our hair out so you don't have to.
- Code: https://github.com/loco2/lolsoap
- Gem: http://rubygems.org/gems/lolsoap
- Docs: http://rubydoc.info/gems/lolsoap/frames
- A collection of classes to make dealing with SOAP requests and responses, and WSDL documents, easier.
- The classes are intended to be loosely coupled and non-prescriptive about how they are used.
- LolSoap does not know anything about what HTTP library you want to use, and does not care whether you're doing the IO in a synchronous or asynchronous fashion. This does mean you have to provide a little bit of glue code, but the benefit is flexibility.
- No monkey-patching.
- Runs without warnings.
# You will need your own HTTP client http = MyHttpClient.new # LolSoap::Client is just a thin wrapper object that handles creating # other objects for you, with a given WSDL file client = LolSoap::Client.new(File.read('lolapi.wsdl')) # Create a request object request = client.request('getLols') # Populate the request with some data. Namespacing is taken care of # using the type data from the WSDL. The WSDL also tells us whether # a given name (e.g. lolFactor below) should be treated as an # attribute or a sub-element. request.body do |b| b.lolFactor '11' b.lolDuration 'lolever' ... end # Request header can be built in a similar way: request.header do |h| h.username 'zomg' ... end # See the full request XML puts request.content # Send that request! raw_response = http.post(request.url, request.headers, request.content) # Create a response object response = client.response(request, raw_response) # Get access to the XML structure (a Nokogiri::XML::Document) p response.doc # Get access to the first node inside the Body p response.body # Turn the body into a hash. The WSDL schema is used to work out which # elements are supposed to be collections and which are just singular. p response.body_hash
- Assumes that you are able to supply a WSDL document for the service.
- Some of the finer details of namespace handling may be glossed over. This is just pragmatism; patches to improve namespace handling are welcome.
These are some of the key classes. If you want, you can require them
require 'lolsoap/request' rather than having to
The main ones:
LolSoap::Request- A HTTP request to be sent
LolSoap::Envelope- The SOAP envelope in the body of a request
LolSoap::Response- The API's response
LolSoap::WSDL- A WSDL document
LolSoap::WSDLParser- Lower level representation of the WSDL document
LolSoap::Builder- XML builder object that knows about types, and therefore how elements should be namespaced.
LolSoap::Fault- A SOAP 'fault' (error)
LolSoap::HashBuilder- Builds hashes from the API response, using the WSDL type data to determine which elements are collection elements.
To append a WSSE node to the header using the
wsse = Akami.wsse wsse.credentials(username, password) request.header.__node__ << wsse.to_xml
Development sponsored by Loco2.
- Use namespaces when looking up definitions
- Added support for referenced attribute groups
- Added support for element references in type definitions
- Added support for operations with multipart header/body
- Added support for multipart messages in WSDL
- Support SOAP Header types
- Generate our own namespace prefixes rather than using ones from the WSDL document. This fixes issues with WSDLs that use the same prefix to denote different namespaces in different places.
- Don't raise an exception on when a SOAP fault is detected. Whether or not this is an exceptional situation should be up to the user, as APIs may use SOAP faults to implement business logic errors.
- Ruby 1.8 support dropped
- Support for WSDL inline type definitions and type extensions
- SOAP 1.1 support
- Better handling of namespaces in the XML schema. You should now be
able to have two types a:foo and b:foo and it will Just Work. This
introduces some API incompatibilities with version 1.1. Specifically,
LolSoap::WSDL#typesis now keyed based on a prefixed type name rather than an unprefixed type name. This shouldn't affect you if you're not using
- Add support for building attributes with
LolSoap::Builderbased on the XML Schema information.
