# LolSoap #



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



[![Build Status](https://secure.travis-ci.org/loco2/lolsoap.png)](http://travis-ci.org/loco2/lolsoap)



## Aims ##



* 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.



## Synopsis ##



``` ruby

# 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

```



## Bugs/Features ##



* 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.



## Overview ##



These are some of the key classes. If you want, you can require them

directly (e.g. `require 'lolsoap/request'` rather than having to

`require 'lolsoap'`).



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



The others:



* `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.



## WSSE ##



To append a WSSE node to the header using the `akami` gem:



```ruby

wsse = Akami.wsse

wsse.credentials(username, password)

request.header.__node__ << wsse.to_xml

```

## Changelog ##



### 0.11 ###



* Use `frozen_string_literal` to improve speed/memory usage



### 0.10 ###



* Added support for using WSDL with abstract types in operation definitions



### 0.9 ###



* Support unqualified form for elements in a schema



### 0.8 ###



* Use namespaces when looking up definitions

* Added support for referenced attribute groups



### 0.7 ###



* Added support for element references in type definitions

* Added support for operations with multipart header/body

* Added support for multipart messages in WSDL



### 0.6 ###



* Support SOAP Header types



### 0.5 ###



* 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.



### 0.4 ###



* 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



### 0.3 ###



* Support for WSDL inline type definitions and type extensions



### 0.2 ###



* 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#types` is now keyed based on a prefixed type name

  rather than an unprefixed type name. This shouldn't affect you if

  you're not using `LolSoap::WSDL#types` directly.

* Add support for building attributes with `LolSoap::Builder` based on

  the XML Schema information.



### 0.1 ###
