Ruby & Savon SOAP client - Unable to find SOAP operation

问题

First time working with a SOAP client, so not sure what I'm doing wrong here.

Here's the SOAP API I'm trying to use: http://services.carsolize.com/BookingServices/DynamicDataService.svc?wsdl

irb(main):018:0> client = Savon.client(wsdl: "http://services.carsolize.com/BookingServices/DynamicDataService.svc?wsdl", convert_request_keys_to: :camelcase)

No matter what I pass to call on client, it tells me:

irb(main):022:0> client.call :service_request, :message => {}
HTTPI GET request to services.carsolize.com (net_http)
Savon::UnknownOperationError: Unable to find SOAP operation: :service_request
Operations provided by your service: []
    from /var/lib/gems/1.9.1/gems/savon-2.2.0/lib/savon/operation.rb:22:in `ensure_exists!'

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

I understand that the SOAP service isn't reporting any operations. Is there any way around this? Is it something on my side that's messing it up, or is it the web service?

Savon version: 2.2.0

回答1:

Savon 2.x.x can access a Web Service without a WSDL. I inspected the WSDL you provided with SoapUI and used the output to create the following code snipped.

It doesn't work because I obviously haven't the correct credentials but it should give you the idea where to continue.

#!ruby
#
gem 'savon', '~> 2.0'
require 'savon'

client = Savon.client(
    endpoint: 'http://services.carsolize.com/BookingServices/DynamicDataService.svc',
    soap_action: "http://tempuri.org/IDynamicDataService/ServiceRequest",
    namespace: 'http://tempuri.org/',
    convert_request_keys_to: :camelcase,
    env_namespace: :soapenv,
    namespace_identifier: :tem,
    log: true,
    log_level: :debug,
    pretty_print_xml: true
)

response = client.call(:service_request,
                       message: {
                          'tem:rqst' => {
                            'BookAsUser' => 'nobody',
                            'Credentials' => {
                              'Password' => 'super secret',
                              'UserName' => 'JoeSixpack'
                            },
                            'Request' => {
                              'ClientIP' => '192.168.142.857'
                            },
                            'RequestType' => 'reservation',
                            'SessionID' => 'AAAAAAAAAAAAAABBBBBBBBBBBBB',
                            'TypeOfService' => 'speedy'
                          }
                       }
                      )
 p response.to_hash
