∟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 HerongYang.com. All Rights Reserved.
#- 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

Accept: multipart/*
Accept: application/soap
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:

soapversion('1.2') changed the Envelope namespace to the correct one: xmlns:soap="http://www.w3.org/2003/05/soap-envelope".
But the service() function still picked up the "port" defined for SOAP 1.1, because it uses "POST http://localhost/soap11 HTTP/1.1".
