SOAP? Setting BODY Manually

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

I am trying to set the body of a SOAP request to a given string (the data may come from a file, for example), but I am getting an extra tag that is causing my call to error at the server. Basically, I want Soap Lite (or another library) to let me fill in EXACTLY what goes between <soap:Body> and </soap:Body> Here is the test code:

#!/usr/bin/perl
use SOAP::Lite +trace;

my ($server, $endpoint, $soapaction, $method, $body, $envelope);

$server = 'http://127.0.0.1';
$endpoint = "$server/Just_Some_Test";
$soapaction = "Just_Some_Test";

# This will eventually come from a file
$body = qq~<wsap:GetData soapenv:encodingStyle="http://schemas.xmlsoap
+.org/soap/encoding/">
         <Just_A_String>
         </Just_A_String>
  </wsap:GetData>
~;

# Set the envelope - Will eventually contain other specific stuff
my $envelope = SOAP::Serializer->new();
$envelope-> register_ns ("http://www.w3.org/2001/XMLSchema-instance", 
+"xsi");
$envelope-> register_ns ("http://www.w3.org/2001/XMLSchema", "xsd");

# Initialize the object
my $getData = SOAP::Lite
    -> serializer ($envelope)
    -> uri ($soapaction)
    -> readable (1)
    -> proxy ($endpoint)
        -> on_fault(sub { my($soap, $res) = @_; 
                 die ref $res ? "ERROR " . $res->faultdetail : "ERROR 
+" .$soap->transport->status, "\n";
               })
;

# Make the call and set the Body of the message
my $response = $getData->call( method => SOAP::Data->type(xml => $body
+) );

if ( $response->fault ) {
    printf "***A fault (%s) occurred: %s\n",
        $response->faultcode, $response->faultstring;
} else {
    print "***Response: " . $response->result . "\n";
}
exit;

The above code produces the following:

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <method xmlns="Just_Some_Test">
      <wsap:GetData soapenv:encodingStyle="http://schemas.xmlsoap.org/
+soap/encoding/">
         <Just_A_String>
         </Just_A_String>
  </wsap:GetData>
    </method>
  </soap:Body>
</soap:Envelope>

I've looked at some of the threads on setting the body to raw XML, but there always seems to be some extra tags left over. The above is almost perfect! I just need to get rid of:

 <method xmlns="Just_Some_Test">
[download]

and it's closing tag. Can this be done?

Rewrite `call` to do what you want sub call { SOAP::Trace::trace('()'); my $self = shift; die "A service address has not been specified either by using SOAP +::Lite->proxy() or a service description)\n" unless defined $self->proxy && UNIVERSAL::isa($self->proxy => +'SOAP::Client'); $self->init_context(); my $serializer = $self->serializer; $serializer->on_nonserialized($self->on_nonserialized); my $response = $self->transport->send_receive( context => $self, # this is provided for context endpoint => $self->endpoint, action => scalar($self->on_action->($serializer->uriformetho +d($_[0]))), # leave only parameters so we can later update them if + required envelope => $serializer->envelope(method => shift, @_), encoding => $serializer->encoding, parts => @{$self->packager->parts} ? $self->packager->parts + : undef, ); return $response if $self->outputxml; my $result = eval { $self->deserializer->deserialize($response) } if $response; if (!$self->transport->is_success \|\| # transport fault $@ \|\| # not deserializible # fault message even if transport OK # or no transport error (for example, fo TCP, POP3, IO impleme +ntations) UNIVERSAL::isa($result => 'SOAP::SOM') && $result->fault) { return ($self->on_fault->($self, $@ ? $@ . ($response \|\| '') : $result) \|\| $result ); # ? # trick editors } # this might be trouble for connection close... return unless $response; # nothing to do for one-ways # little bit tricky part that binds in/out parameters if (UNIVERSAL::isa($result => 'SOAP::SOM') && ($result->paramsout \|\| $result->headers) && $serializer->signature) { my $num = 0; my %signatures = map {$_ => $num++} @{$serializer->signature}; for ($result->dataof(SOAP::SOM::paramsout), $result->dataof(SO +AP::SOM::headers)) { my $signature = join $;, $_->name, $_->type \|\| ''; if (exists $signatures{$signature}) { my $param = $signatures{$signature}; my($value) = $_->value; # take first value # fillup parameters UNIVERSAL::isa($_[$param] => 'SOAP::Data') ? $_[$param]->SOAP::Data::value($value) : UNIVERSAL::isa($_[$param] => 'ARRAY') ? (@{$_[$param]} = @$value) : UNIVERSAL::isa($_[$param] => 'HASH') ? (%{$_[$param]} = %$value) : UNIVERSAL::isa($_[$param] => 'SCALAR') ? (${$_[$param]} = $$value) : ($_[$param] = $value) } } } return $result; } # end of call() [download] On second thought, it looks as though you should create a custom serializer	[reply] [d/l] [select]

Sorry for the delay in responding (I've been out for a few days). Thank you very much for taking the time to respond. I may be able to define the name of the function and have that removed from the file, so I can then get away without a custom serializer. Otherwise, I have some work ahead of me! Thanks again, Marc	[reply]
