soapversion('1.2') Sets Correct Envelope namespace

This section provides a tutorial example on how to use soapversion('1.2') to tell service() to use the correct namespace for the Envelope.

From previous tutorial, I learned that the service() function uses SOAP 1.1 by default and it put the wrong namespace to the Envelope. Now let me force it to use SOAP 1.2 and see what happens:

#- GetSpeech_WSDL_localhost_1_2.pl
#- Copyright (c) 2009 by Dr. Herong Yang, herongyang.com
#- All rights reserved
#
   use SOAP::Lite +trace;
   my $client = SOAP::Lite->new()
      ->soapversion('1.2')
      ->service('file:///C:/herong/GetSpeech.wsdl')
      ->readable('true');
      
#- Overriding the constant for SOAP 1.2
   $SOAP::Constants::DEFAULT_HTTP_CONTENT_TYPE 
      = 'application/soap+xml';

   $client->GetSpeech('To be, or not to be');

Result of GetSpeech_WSDL_localhost_1_2.pl:

POST http://localhost/soap11 HTTP/1.1

Content-Length: 831

      <Request xsi:type="s:string">To be, or not to be</Request>
    </tns:GetSpeech>
  </soap:Body>
</soap:Envelope>
...
500 Can't connect to localhost:80 (connect: Unknown error)

Note that:

The request looks good to me now. I will try it with the real Web service server at xmlme.com in the next tutorial.
