Getting my feet wet

[Hameed Gifford]

Hi all. I am getting into the API of a service that I use, and they implement SOAP, so I got Savon working on my machine and went to task learning this stuff.

Well, I've done this:

require 'savon'

client = Savon.client(wsdl: "WSDL_HYPERLINK")

and got all the operations, and went to call the login operation:

response = client.call(:login) do

message(loginId: "username", password: "password")

end

replacing the username and password with the correct fields, obviously.

However, I get this error:

Savon::SOAPFault: (env:Client) caught exception while handling request: unexpected encoding style: expected=http://schemas.xmlsoap.org/soap/encoding/, actual=

        from /var/lib/gems/2.0.0/gems/savon-2.5.1/lib/savon/response.rb:85:in `raise_soap_and_http_errors!'

        from /var/lib/gems/2.0.0/gems/savon-2.5.1/lib/savon/response.rb:14:in `initialize'

        from /var/lib/gems/2.0.0/gems/savon-2.5.1/lib/savon/operation.rb:64:in `new'

        from /var/lib/gems/2.0.0/gems/savon-2.5.1/lib/savon/client.rb:36:in `call'

        from (irb):44

        from /usr/bin/irb:12:in `<main>'

What's going on here? The documentation on my service's API site says that all errors are thrown as SOAP faults, but how do I read this?

Just as information, the service says that the login method has two parameters:

1) loginId of type string

2) password of type string

Am I entering the "parameters" in the incorrect way, i.e. should they not me a locals message?

Thanks.

Hi,

you should switch on logging with

log: true,

log_level: :debug,

pretty_print_xml: true

If that doesn't give you a clue then you should install SoapUI and try first to call your service sucessfully using that tool. In the next step you should then build your successful message using Savon.

The service is currently down, but thanks for leading me in those directions... I will definitely use SoapUI until I'm comfortable with this. There is very little learning material on any SOAP library out there.
