Soap

SOAP client for Elixir programming language

Installation

1. Add soap to your deps:

def deps do
  [{:soap, "~> 1.0"}]
end

2. Add soap to the list of application dependencies(or just use extra_applications):

def application do
  [applications: [:logger, :soap]]
end

Configuration

Configure version of SOAP protocol. Supported versions 1.1(default) and 1.2.

config :soap, :globals, version: "1.1"

Allow empty soapAction attribute in operation definition

config :soap, :globals, allow_empty_soap_action: true

In case of schema_namespace is not present in types definitions

config :soap, :globals, absent_schema_namespace: true

Usage

The documentation is available on HexDocs.

Parse WSDL file for execution of actions on its basis:

iex(1)> {:ok, wsdl} = Soap.init_model(wsdl_path, :url)
{:ok, parsed_wsdl}

Get list of available operations:

iex(2)> Soap.operations(wsdl)
[
  %{
    input: %{body: nil, header: nil},
    name: "Add",
    soap_action: "http://tempuri.org/Add"
  },
  %{
    input: %{body: nil, header: nil},
    name: "Subtract",
    soap_action: "http://tempuri.org/Subtract"
  },
  %{
    input: %{body: nil, header: nil},
    name: "Multiply",
    soap_action: "http://tempuri.org/Multiply"
  },
  %{
    input: %{body: nil, header: nil},
    name: "Divide",
    soap_action: "http://tempuri.org/Divide"
  }
]

Call action:

wsdl_path = "http://www.dneonline.com/calculator.asmx?WSDL"
action = "Add"
params = %{intA: 1, intB: 2}

iex(3)> {:ok, response} = Soap.call(wsdl, action, params)
{:ok,
 %Soap.Response{
   body: "<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"><soap:Body><AddResponse xmlns=\"http://tempuri.org/\"><AddResult>3</AddResult></AddResponse></soap:Body></soap:Envelope>",
   headers: [
     {"Cache-Control", "private, max-age=0"},
     {"Content-Length", "325"},
     {"Content-Type", "text/xml; charset=utf-8"},
     {"Server", "Microsoft-IIS/7.5"},
     {"X-AspNet-Version", "2.0.50727"},
     {"X-Powered-By", "ASP.NET"},
     {"Date", "Thu, 14 Feb 2019 07:52:04 GMT"}
   ],
   request_url: "http://www.dneonline.com/calculator.asmx",
   status_code: 200
 }}

Parse response:

iex(4)> Soap.Response.parse(response)
%{AddResponse: %{AddResult: "3"}}

To add SOAP headers, pass in a {headers, params} tuple instead of just params:

{:ok, %Soap.Response{}} = Soap.call(wsdl, action, {%{Token: "foo"}, params})
