对 Ruby 使用 SOAP 的最佳方式是什么？

Try SOAP4R

• SOAP4R
• Getting Started with SOAP4R

And I just heard about this on the Rails Envy Podcast (ep 31):

• WS-Deathstar SOAP walkthrough

We used the built in soap/wsdlDriver class, which is actually SOAP4R. It's dog slow, but really simple. The SOAP4R that you get from gems/etc is just an updated version of the same thing.

Example code:

require 'soap/wsdlDriver'


client = SOAP::WSDLDriverFactory.new( 'http://example.com/service.wsdl' ).create_rpc_driver
result = client.doStuff();

That's about it

Kent Sibilev from Datanoise had also ported the Rails ActionWebService library to Rails 2.1 (and above). This allows you to expose your own Ruby-based SOAP services. He even has a scaffold/test mode which allows you to test your services using a browser.

We switched from Handsoap to Savon.

Here is a series of blog posts comparing the two client libraries.

I built Savon to make interacting with SOAP webservices via Ruby as easy as possible.
I'd recommend you check it out.

I also recommend Savon. I spent too many hours trying to deal with Soap4R, without results. Big lack of functionality, no doc.

Savon is the answer for me.

Just got my stuff working within 3 hours using Savon.

The Getting Started documentation on Savon's homepage was really easy to follow - and actually matched what I was seeing (not always the case)

I was having the same issue, switched to Savon and then just tested it on an open WSDL (I used http://www.webservicex.net/geoipservice.asmx?WSDL) and so far so good!

I have used HTTP call like below to call a SOAP method,

require 'net/http'


class MyHelper
def initialize(server, port, username, password)
@server = server
@port = port
@username = username
@password = password


puts "Initialised My Helper using #{@server}:#{@port} username=#{@username}"
end






def post_job(job_name)


puts "Posting job #{job_name} to update order service"


job_xml ="<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ns=\"http://test.com/Test/CreateUpdateOrders/1.0\">
<soapenv:Header/>
<soapenv:Body>
<ns:CreateTestUpdateOrdersReq>
<ContractGroup>ITE2</ContractGroup>
<ProductID>topo</ProductID>
<PublicationReference>#{job_name}</PublicationReference>
</ns:CreateTestUpdateOrdersReq>
</soapenv:Body>
</soapenv:Envelope>"


@http = Net::HTTP.new(@server, @port)
puts "server: " + @server  + "port  : " + @port
request = Net::HTTP::Post.new(('/XISOAPAdapter/MessageServlet?/Test/CreateUpdateOrders/1.0'), initheader = {'Content-Type' => 'text/xml'})
request.basic_auth(@username, @password)
request.body = job_xml
response = @http.request(request)


puts "request was made to server " + @server


validate_response(response, "post_job_to_pega_updateorder job", '200')


end






private


def validate_response(response, operation, required_code)
if response.code != required_code
raise "#{operation} operation failed. Response was [#{response.inspect} #{response.to_hash.inspect} #{response.body}]"
end
end
end


/*
test = MyHelper.new("mysvr.test.test.com","8102","myusername","mypassword")
test.post_job("test_201601281419")
*/

Hope it helps. Cheers.

I have used SOAP in Ruby when i've had to make a fake SOAP server for my acceptance tests. I don't know if this was the best way to approach the problem, but it worked for me.

I have used Sinatra gem (I wrote about creating mocking endpoints with Sinatra here) for server and also Nokogiri for XML stuff (SOAP is working with XML).

So, for the beginning I have create two files (e.g. config.rb and responses.rb) in which I have put the predefined answers that SOAP server will return. In config.rb I have put the WSDL file, but as a string.

@@wsdl = '<wsdl:definitions name="StockQuote"
targetNamespace="http://example.com/stockquote.wsdl"
xmlns:tns="http://example.com/stockquote.wsdl"
xmlns:xsd1="http://example.com/stockquote.xsd"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns="http://schemas.xmlsoap.org/wsdl/">
.......
</wsdl:definitions>'

In responses.rb I have put samples for responses that SOAP server will return for different scenarios.

@@login_failure = "<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<LoginResponse xmlns="http://tempuri.org/">
<LoginResult xmlns:a="http://schemas.datacontract.org/2004/07/WEBMethodsObjects" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<a:Error>Invalid username and password</a:Error>
<a:ObjectInformation i:nil="true"/>
<a:Response>false</a:Response>
</LoginResult>
</LoginResponse>
</s:Body>
</s:Envelope>"

So now let me show you how I have actually created the server.

require 'sinatra'
require 'json'
require 'nokogiri'
require_relative 'config/config.rb'
require_relative 'config/responses.rb'


after do
# cors
headers({
"Access-Control-Allow-Origin" => "*",
"Access-Control-Allow-Methods" => "POST",
"Access-Control-Allow-Headers" => "content-type",
})


# json
content_type :json
end


#when accessing the /HaWebMethods route the server will return either the WSDL file, either and XSD (I don't know exactly how to explain this but it is a WSDL dependency)
get "/HAWebMethods/" do
case request.query_string
when 'xsd=xsd0'
status 200
body = @@xsd0
when 'wsdl'
status 200
body = @@wsdl
end
end


post '/HAWebMethods/soap' do
request_payload = request.body.read
request_payload = Nokogiri::XML request_payload
request_payload.remove_namespaces!


if request_payload.css('Body').text != ''
if request_payload.css('Login').text != ''
if request_payload.css('email').text == some username && request_payload.css('password').text == some password
status 200
body = @@login_success
else
status 200
body = @@login_failure
end
end
end
end

I hope you'll find this helpful!
