Small Ruby code example

Fyi: I renamed node-monitor-state to node-state as it now changes both the monitor and session_enabled states.

Hey, josb. A user posted to the blog comments that the link is not working any longer. Is there a new location for the wrapper files?

The site should be working again. There was a nasty bug in the library that prevented the use of multiple loadbalancers in the same program. This bug has been fixed. Feedback welcome.

Code question:

 

 

I've taken a look at your library but was unable to get it working. It looks like this API verifies on a per session basis and not a per request basis. I've not dealt with a SOAP API that does verification in this matter and was wondering if anyone had a suggestion or could point me to what I've missed. The exception is:

 

 

 

Errno::ECONNREFUSED: Connection refused - connect(2) (://:0)

The code of interest is:

 

73 @name = name

 

74 @driver = SOAP::WSDLDriverFactory.new(wsdl_name).create_rpc_driver

 

75

 

76 verify_mode = OpenSSL::SSL::VERIFY_NONE

 

77 @driver.options['protocol.http.ssl_config.verify_mode'] = verify_mode

 

78 @driver.options['protocol.http.ssl_config.verify_callback'] = lambda {|is_ok, ctx| true}

 

79 @driver.options['protocol.http.basic_auth'] << mod.base.basic_auth

 

80 if mod.base.connect_timeout

 

81 @driver.options["protocol.http.connect_timeout"] = mod.base.connect_timeout

 

82 end

 

 

 

To me this looks like it is trying to access the WSDL to try to generate the methods before I have set the authentication credentials. The only thing that looks odd to me is that at the end of the exception it has (://:0). Does that mean it tried to connect to "://:0" and not "http://hostname/:port"? If so that is even more confusing because I have specified "method" and "endpoint" and if method is https it should be port 443

 

 

I would appreciate any insight.

 

 

Thanks,
