I am getting an error when trying to access a web service via soap
soap_client = SOAP::WSDLDriverFactory.new("http://api.upsidewireless.com/soap/Authentication.asmx?WSDL") driver = soap_client.createDriver @p = driver.GetParameters(:username => 'uname', :password => 'pword') #ERROR => wrong number of arguments (1 for 2) I can clearly see two arguments for this method call. Why would I be getting this error?
@james has the right answer, but just for future reference (and because this has bitten me before), this call:
driver.GetParameters(:username => 'uname', :password => 'pword') is passing one parameter: a hash. Each of your elements isn't one thing; it's a hash element with a key and a value. Ruby notices this and puts them all into one hash. So you are effectively passing this:
driver.GetParameters({:username => 'uname', :password => 'pword'}) This is one of the confusing things about calling a method in Ruby. If you pass a hash as the last (or only) parameter, you can leave off the {}, and most people do. Makes it hard to figure out sometimes.
If you actually wanted to pass this as two parameters:
driver.GetParameters('uname', 'pword') 
WSDLDriver is deprecated (called from createDriver). You should use 'create_rpc_driver'. I get back a response with that method from your example. Is there some reason not to use 'create_rpc_driver' ?
