Custom serializer and Apache2::SOAP

john_oshea has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

I have a Apache2::SOAP system working all fine and dandy, and now I want to add in a custom serializer and I'm having a total brainfart as to where to actually add it. The standalone server example (following) does what I want, but I can't actually see where I'd add in the equivalent of the ->serializer() line in a Apache2::SOAP setup:

my $daemon = SOAP::Transport::HTTP::Daemon ->new( LocalAddr => 'localhost', LocalPort => 8080, Re +use => 1 ) ->serializer(My::Serializer->new) ->dispatch_to('My::Server'); BEGIN { package My::Serializer; @My::Serializer::ISA = 'SOAP::Serializer'; sub envelope { $_[2] = (SOAP::Data->name($_[2]) ->prefix('foo') ->uri('http://www.example.org') ) if $_[1] =~ /^(?:method|response)$/; shift->SUPER::envelope(@_); } }

The dispatch_to line in the appropriate httpd.conf section? Somewhere else? Any pointers would be very gratefully accepted.

Thanks

    The way that I have done this in the past is to create my own class that inherits from Apache::SOAP and incorporates a new constructor that includes the call to the serializer function.

    For example:

    package My::SOAP; use Apache::SOAP; use strict; use vars qw( @ISA $VERSION ); # This class inherits from the Apache::SOAP class and is intended to + provide # functionality relating to the SOAP server itself, rather than the +exposed # web services. @ISA = qw( SOAP::Transport::HTTP::Apache ); my $server = __PACKAGE__->new; sub new { my $self = shift; unless( ref $self ) { $self = __PACKAGE__->SUPER::new( @_ ); $self->serializer( My::SOAP::Serialiser->new ); # The following on_action handler is intended to make this w +eb service .NET # friendly by modifying the SOAPAction header to fit the for +m of URI#method # (the form preferred by SOAP::Lite) where the SOAPAction he +ader is of the # form URI/method (that employed by the .NET framework). $self->on_action( sub { ( my $action = shift ) =~ s/^("?)(.*)\1$/$2/; if( $action && $action ne join( '#', @_ ) && $action ne join( '/', @_ ) && ( substr( $_[0], -1, 1 ) ne '/' || $action ne join( '', @_ ))) { $self->action( join '#', @_ ); } } ); } return $self; } 1; __END__

    (This code, although slightly modified to protect the innocent, is from an Apache::SOAP server implementation that was developed for interface from .NET solution components and shows one way to implement your own serialiser within Apache::SOAP derived solutions).

     

    perl -le "print unpack'N', pack'B32', '00000000000000000000001000000000'"

      Thank you. That makes so much more sense than the arrant nonsense I was attempting yesterday... ;-)
