</soap:Envelope>
=item use_prefix(boolean)
Deprecated. Use the C<ns()> and C<default_ns> methods described above.
Shortcut for C<< serializer->use_prefix() >>. This lets you turn on/off the
use of a namespace prefix for the children of the /Envelope/Body element.
Default is 'true'.
When use_prefix is set to 'true', serialized XML will look like this:
<SOAP-ENV:Envelope ...attributes skipped>
<SOAP-ENV:Body>
<namesp1:mymethod xmlns:namesp1="urn:MyURI" />
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
When use_prefix is set to 'false', serialized XML will look like this:
<SOAP-ENV:Envelope ...attributes skipped>
<SOAP-ENV:Body>
<mymethod xmlns="urn:MyURI" />
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Some .NET web services have been reported to require this XML namespace idiom.
=item soapversion(optional value)
$client->soapversion('1.2');
If no parameter is given, returns the current version of SOAP that is being
used by the client object to encode requests. If a parameter is given, the
method attempts to set that as the version of SOAP being used.
The value should be either 1.1 or 1.2.
=item envprefix(QName)
$client->envprefix('env');
This method is a shortcut for:
$client->serializer->envprefix(QName);
Gets or sets the namespace prefix for the SOAP namespace. The default is
SOAP.
The prefix itself has no meaning, but applications may wish to chose one
explicitly to denote different versions of SOAP or the like.
=item encprefix(QName)
$client->encprefix('enc');
This method is a shortcut for:
$client->serializer->encprefix(QName);
Gets or sets the namespace prefix for the encoding rules namespace.
The default value is SOAP-ENC.
=back
While it may seem to be an unnecessary operation to set a value that isn't
relevant to the message, such as the namespace labels for the envelope and
encoding URNs, the ability to set these labels explicitly can prove to be a
great aid in distinguishing and debugging messages on the server side of
operations.
=over
=item encoding(encoding URN)
$client->encoding($soap_12_encoding_URN);
This method is a shortcut for:
$client->serializer->encoding(args);
Where the earlier method dealt with the label used for the attributes related
to the SOAP encoding scheme, this method actually sets the URN to be specified
as the encoding scheme for the message. The default is to specify the encoding
for SOAP 1.1, so this is handy for applications that need to encode according
to SOAP 1.2 rules.
=item typelookup
$client->typelookup;
This method is a shortcut for:
$client->serializer->typelookup;
Gives the application access to the type-lookup table from the serializer
object. See the section on L<SOAP::Serializer>.
=item uri(service specifier)
Deprecated - the C<uri> subroutine is deprecated in order to provide a more
intuitive naming scheme for subroutines that set namespaces. In the future,
you will be required to use either the C<ns()> or C<default_ns()> subroutines
instead of C<uri()>.
$client->uri($service_uri);
This method is a shortcut for:
$client->serializer->uri(service);
The URI associated with this accessor on a client object is the
service-specifier for the request, often encoded for HTTP-based requests as
the SOAPAction header. While the names may seem confusing, this method
doesn't specify the endpoint itself. In most circumstances, the C<uri> refers
to the namespace used for the request.
Often times, the value may look like a valid URL. Despite this, it doesn't
have to point to an existing resource (and often doesn't). This method sets
and retrieves this value from the object. Note that no transport code is
triggered by this because it has no direct effect on the transport of the
object.
=item multirefinplace(boolean)
$client->multirefinplace(1);
This method is a shortcut for:
$client->serializer->multirefinplace(boolean);
Controls how the serializer handles values that have multiple references to
them. Recall from previous SOAP chapters that a value may be tagged with an
identifier, then referred to in several places. When this is the case for a
value, the serializer defaults to putting the data element towards the top of
the message, right after the opening tag of the method-specification. It is
serialized as a standalone entity with an ID that is then referenced at the
relevant places later on. If this method is used to set a true value, the
behavior is different. When the multirefinplace attribute is true, the data
is serialized at the first place that references it, rather than as a separate
element higher up in the body. This is more compact but may be harder to read
or trace in a debugging environment.
=item parts( ARRAY )
Used to specify an array of L<MIME::Entity>'s to be attached to the
transmitted SOAP message. Attachments that are returned in a response can be
accessed by C<SOAP::SOM::parts()>.
=item self
$ref = SOAP::Lite->self;
Returns an object reference to the default global object the C<SOAP::Lite>
package maintains. This is the object that processes many of the arguments
when provided on the use line.
=back
The following method isn't an accessor style of method but neither does it fit
with the group that immediately follows it:
=over
=item call(arguments)
$client->call($method => @arguments);
As has been illustrated in previous chapters, the C<SOAP::Lite> client objects
can manage remote calls with auto-dispatching using some of Perl's more
elaborate features. call is used when the application wants a greater degree
of control over the details of the call itself. The method may be built up
from a L<SOAP::Data> object, so as to allow full control over the namespace
associated with the tag, as well as other attributes like encoding. This is
also important for calling methods that contain characters not allowable in
Perl function names, such as A.B.C.
=back
The next four methods used in the C<SOAP::Lite> class are geared towards
handling the types of events than can occur during the message lifecycle. Each
of these sets up a callback for the event in question:
=over
=item on_action(callback)
$client->on_action(sub { qq("$_[0]") });
Triggered when the transport object sets up the SOAPAction header for an
HTTP-based call. The default is to set the header to the string, uri#method,
in which URI is the value set by the uri method described earlier, and method
is the name of the method being called. When called, the routine referenced
(or the closure, if specified as in the example) is given two arguments, uri
and method, in that order.
.NET web services usually expect C</> as separator for C<uri> and C<method>.
To change SOAP::Lite's behaviour to use uri/method as SOAPAction header, use
the following code:
$client->on_action( sub { join '/', @_ } );
=item on_fault(callback)
$client->on_fault(sub { popup_dialog($_[1]) });
Triggered when a method call results in a fault response from the server.
When it is called, the argument list is first the client object itself,
followed by the object that encapsulates the fault. In the example, the fault
object is passed (without the client object) to a hypothetical GUI function
that presents an error dialog with the text of fault extracted from the object
(which is covered shortly under the L<SOAP::SOM> methods).
=item on_nonserialized(callback)
$client->on_nonserialized(sub { die "$_[0]?!?" });
Occasionally, the serializer may be given data it can't turn into SOAP-savvy
XML; for example, if a program bug results in a code reference or something
similar being passed in as a parameter to method call. When that happens, this
callback is activated, with one argument. That argument is the data item that
could not be understood. It will be the only argument. If the routine returns,
the return value is pasted into the message as the serialization. Generally,
an error is in order, and this callback allows for control over signaling that
error.
=item on_debug(callback)
$client->on_debug(sub { print @_ });
Deprecated. Use the global +debug and +trace facilities described in
L<SOAP::Trace>
Note that this method will not work as expected: Instead of affecting the
debugging behaviour of the object called on, it will globally affect the
debugging behaviour for all objects of that class.
=back
=head1 WRITING A SOAP CLIENT
This chapter guides you to writing a SOAP client by example.
The SOAP service to be accessed is a simple variation of the well-known
hello world program. It accepts two parameters, a name and a given name,
and returns "Hello $given_name $name".
We will use "Martin Kutter" as the name for the call, so all variants will
print the following message on success:
Hello Martin Kutter!
=head2 SOAP message styles
There are three common (and one less common) variants of SOAP messages.
These address the message style (positional parameters vs. specified message
documents) and encoding (as-is vs. typed).
The different message styles are:
=over
=item * rpc/encoded
Typed, positional parameters. Widely used in scripting languages.
The type of the arguments is included in the message.
Arrays and the like may be encoded using SOAP encoding rules (or others).
=item * rpc/literal
As-is, positional parameters. The type of arguments is defined by some
pre-exchanged interface definition.
=item * document/encoded
Specified message with typed elements. Rarely used.
=item * document/literal
Specified message with as-is elements. The message specification and
element types are defined by some pre-exchanged interface definition.
=back
As of 2008, document/literal has become the predominant SOAP message
variant. rpc/literal and rpc/encoded are still in use, mainly with scripting
languages, while document/encoded is hardly used at all.
You will see clients for the rpc/encoded and document/literal SOAP variants in
this section.
=head2 Example implementations
=head3 RPC/ENCODED
Rpc/encoded is most popular with scripting languages like perl, php and python
without the use of a WSDL. Usual method descriptions look like this:
Method: sayHello(string, string)
Parameters:
name: string
givenName: string
Such a description usually means that you can call a method named "sayHello"
with two positional parameters, "name" and "givenName", which both are
strings.
The message corresponding to this description looks somewhat like this:
<sayHello xmlns="urn:HelloWorld">
<s-gensym01 xsi:type="xsd:string">Kutter</s-gensym01>
<s-gensym02 xsi:type="xsd:string">Martin</s-gensym02>
</sayHello>
Any XML tag names may be used instead of the "s-gensym01" stuff - parameters
are positional, the tag names have no meaning.
A client producing such a call is implemented like this:
use SOAP::Lite;
my $soap = SOAP::Lite->new( proxy => 'http://localhost:81/soap-wsdl-test/helloworld.pl');
$soap->default_ns('urn:HelloWorld');
my $som = $soap->call('sayHello', 'Kutter', 'Martin');
die $som->faultstring if ($som->fault);
print $som->result, "\n";
You can of course use a one-liner, too...
Sometimes, rpc/encoded interfaces are described with WSDL definitions.
A WSDL accepting "named" parameters with rpc/encoded looks like this:
<definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:s="http://www.w3.org/2001/XMLSchema"
xmlns:s0="urn:HelloWorld"
targetNamespace="urn:HelloWorld"
xmlns="http://schemas.xmlsoap.org/wsdl/">
<types>
<s:schema targetNamespace="urn:HelloWorld">
</s:schema>
</types>
<message name="sayHello">
<part name="name" type="s:string" />
<part name="givenName" type="s:string" />
</message>
<message name="sayHelloResponse">
<part name="sayHelloResult" type="s:string" />
</message>
<portType name="Service1Soap">
<operation name="sayHello">
<input message="s0:sayHello" />
<output message="s0:sayHelloResponse" />
</operation>
</portType>
<binding name="Service1Soap" type="s0:Service1Soap">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http"
style="rpc" />
<operation name="sayHello">
<soap:operation soapAction="urn:HelloWorld#sayHello"/>
<input>
<soap:body use="encoded"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
</input>
<output>
<soap:body use="encoded"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
</output>
</operation>
</binding>
<service name="HelloWorld">
<port name="HelloWorldSoap" binding="s0:Service1Soap">
<soap:address location="http://localhost:81/soap-wsdl-test/helloworld.pl" />
</port>
</service>
</definitions>
The message corresponding to this schema looks like this:
<sayHello xmlns="urn:HelloWorld">
<name xsi:type="xsd:string">Kutter</name>
<givenName xsi:type="xsd:string">Martin</givenName>
</sayHello>
A web service client using this schema looks like this:
use SOAP::Lite;
my $soap = SOAP::Lite->service("file:say_hello_rpcenc.wsdl");
eval { my $result = $soap->sayHello('Kutter', 'Martin'); };
if ($@) {
die $@;
}
print $som->result();
You may of course also use the following one-liner:
perl -MSOAP::Lite -e 'print SOAP::Lite->service("file:say_hello_rpcenc.wsdl")\
->sayHello('Kutter', 'Martin'), "\n";'
A web service client (without a service description) looks like this.
use SOAP::Lite;
my $soap = SOAP::Lite->new( proxy => 'http://localhost:81/soap-wsdl-test/helloworld.pl');
$soap->default_ns('urn:HelloWorld');
my $som = $soap->call('sayHello',
SOAP::Data->name('name')->value('Kutter'),
SOAP::Data->name('givenName')->value('Martin')
);
die $som->faultstring if ($som->fault);
print $som->result, "\n";
=head3 RPC/LITERAL
SOAP web services using the document/literal message encoding are usually
described by some Web Service Definition. Our web service has the following
WSDL description:
<definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:s="http://www.w3.org/2001/XMLSchema"

<service name="HelloWorld">
<port name="HelloWorldSoap" binding="s0:Service1Soap">
<soap:address location="http://localhost:80//helloworld.pl" />
</port>
</service>
</definitions>
The XML message (inside the SOAP Envelope) look like this:
<ns0:sayHello xmlns:ns0="urn:HelloWorld">
<parameters>
<name>Kutter</name>
<givenName>Martin</givenName>
</parameters>
</ns0:sayHello>
<sayHelloResponse xmlns:ns0="urn:HelloWorld">
<parameters>
<sayHelloResult>Hello Martin Kutter!</sayHelloResult>
</parameters>
</sayHelloResponse>
This is the SOAP::Lite implementation for the web service client:
use SOAP::Lite +trace;
my $soap = SOAP::Lite->new( proxy => 'http://localhost:80/helloworld.pl');
$soap->on_action( sub { "urn:HelloWorld#sayHello" });
$soap->autotype(0)->readable(1);
$soap->default_ns('urn:HelloWorld');
my $som = $soap->call('sayHello', SOAP::Data->name('parameters')->value(
\SOAP::Data->value([
SOAP::Data->name('name')->value( 'Kutter' ),
SOAP::Data->name('givenName')->value('Martin'),
]))
);
die $som->fault->{ faultstring } if ($som->fault);
print $som->result, "\n";

=head1 SECURITY
For security reasons, the existing path for Perl modules (C<@INC>) will be
disabled once you have chosen dynamic deployment and specified your own
C<PATH/>. If you wish to access other modules in your included package you
have several options:
=over 4
=item 1
Switch to static linking:
use MODULE;
$server->dispatch_to('MODULE');
Which can also be useful when you want to import something specific from the
deployed modules:
use MODULE qw(import_list);
=item 2
Change C<use> to C<require>. The path is only unavailable during the
initialization phase. It is available once more during execution. Therefore,
if you utilize C<require> somewhere in your package, it will work.
=item 3
Wrap C<use> in an C<eval> block:
eval 'use MODULE qw(import_list)'; die if $@;
=item 4
Set your include path in your package and then specify C<use>. Don't forget to
put C<@INC> in a C<BEGIN{}> block or it won't work. For example,
BEGIN { @INC = qw(my_directory); use MODULE }

=head1 INTEROPERABILITY
=head2 Microsoft .NET client with SOAP::Lite Server
In order to use a .NET client with a SOAP::Lite server, be sure you use fully
qualified names for your return values. For example:
return SOAP::Data->name('myname')
->type('string')
->uri($MY_NAMESPACE)
->value($output);
In addition see comment about default encoding in .NET Web Services below.
=head2 SOAP::Lite client with a .NET server
If experiencing problems when using a SOAP::Lite client to call a .NET Web
service, it is recommended you check, or adhere to all of the following
recommendations:
=over 4
=item Declare a proper soapAction in your call
For example, use
C<on_action( sub { 'http://www.myuri.com/WebService.aspx#someMethod'; } )>.
=item Disable charset definition in Content-type header
Some users have said that Microsoft .NET prefers the value of
the Content-type header to be a mimetype exclusively, but SOAP::Lite specifies
a character set in addition to the mimetype. This results in an error similar
to:
Server found request content type to be 'text/xml; charset=utf-8',
but expected 'text/xml'
To turn off this behavior specify use the following code:
use SOAP::Lite;
$SOAP::Constants::DO_NOT_USE_CHARSET = 1;
# The rest of your code
=item Use fully qualified name for method parameters
For example, the following code is preferred:
SOAP::Data->name(Query => 'biztalk')
->uri('http://tempuri.org/')
As opposed to:
SOAP::Data->name('Query' => 'biztalk')
=item Place method in default namespace
For example, the following code is preferred:
my $method = SOAP::Data->name('add')
->attr({xmlns => 'http://tempuri.org/'});
my @rc = $soap->call($method => @parms)->result;
As opposed to:
my @rc = $soap->call(add => @parms)->result;
# -- OR --
my @rc = $soap->add(@parms)->result;
=item Disable use of explicit namespace prefixes
Some user's have reported that .NET will simply not parse messages that use
namespace prefixes on anything but SOAP elements themselves. For example, the
following XML would not be parsed:
<SOAP-ENV:Envelope ...attributes skipped>
<SOAP-ENV:Body>
<namesp1:mymethod xmlns:namesp1="urn:MyURI" />
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
SOAP::Lite allows users to disable the use of explicit namespaces through the
C<use_prefix()> method. For example, the following code:
$som = SOAP::Lite->uri('urn:MyURI')
->proxy($HOST)
->use_prefix(0)
->myMethod();
Will result in the following XML, which is more palatable by .NET:
<SOAP-ENV:Envelope ...attributes skipped>
<SOAP-ENV:Body>
<mymethod xmlns="urn:MyURI" />
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
=item Modify your .NET server, if possible
Stefan Pharies <stefanph@microsoft.com>:
SOAP::Lite uses the SOAP encoding (section 5 of the soap 1.1 spec), and
the default for .NET Web Services is to use a literal encoding. So
elements in the request are unqualified, but your service expects them to
be qualified. .Net Web Services has a way for you to change the expected
message format, which should allow you to get your interop working.
At the top of your class in the asmx, add this attribute (for Beta 1):
[SoapService(Style=SoapServiceStyle.RPC)]
Another source said it might be this attribute (for Beta 2):
[SoapRpcService]
Full Web Service text may look like:
<%@ WebService Language="C#" Class="Test" %>
using System;
using System.Web.Services;
using System.Xml.Serialization;
[SoapService(Style=SoapServiceStyle.RPC)]
public class Test : WebService {
[WebMethod]
public int add(int a, int b) {
return a + b;
}
}
Another example from Kirill Gavrylyuk <kirillg@microsoft.com>:
"You can insert [SoapRpcService()] attribute either on your class or on
operation level".
<%@ WebService Language=CS class="DataType.StringTest"%>
namespace DataType {
using System;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Web.Services.Description;
[SoapRpcService()]
public class StringTest: WebService {
[WebMethod]
[SoapRpcMethod()]
public string RetString(string x) {
return(x);
}
}
}
Example from Yann Christensen <yannc@microsoft.com>:
using System;
using System.Web.Services;
using System.Web.Services.Protocols;
namespace Currency {
[WebService(Namespace="http://www.yourdomain.com/example")]
[SoapRpcService]

CGI scripts may not work under IIS unless scripts use the C<.pl> extension,
opposed to C<.cgi>.
=item Java SAX parser unable to parse message composed by SOAP::Lite
In some cases SOAP messages created by C<SOAP::Lite> may not be parsed
properly by a SAX2/Java XML parser. This is due to a known bug in
C<org.xml.sax.helpers.ParserAdapter>. This bug manifests itself when an
attribute in an XML element occurs prior to the XML namespace declaration on
which it depends. However, according to the XML specification, the order of
these attributes is not significant.

=head1 PERFORMANCE
=over 4
=item Processing of XML encoded fragments
C<SOAP::Lite> is based on L<XML::Parser> which is basically wrapper around
James Clark's expat parser. Expat's behavior for parsing XML encoded string
can affect processing messages that have lot of encoded entities, like XML
fragments, encoded as strings. Providing low-level details, parser will call
char() callback for every portion of processed stream, but individually for
every processed entity or newline. It can lead to lot of calls and additional
memory manager expenses even for small messages. By contrast, XML messages
which are encoded as base64Binary, don't have this problem and difference in
processing time can be significant. For XML encoded string that has about 20
lines and 30 tags, number of call could be about 100 instead of one for
the same string encoded as base64Binary.
Since it is parser's feature there is NO fix for this behavior (let me know
if you find one), especially because you need to parse message you already
got (and you cannot control content of this message), however, if your are
in charge for both ends of processing you can switch encoding to base64 on
sender's side. It will definitely work with SOAP::Lite and it B<may> work with
other toolkits/implementations also, but obviously I cannot guarantee that.
If you want to encode specific string as base64, just do
C<< SOAP::Data->type(base64 => $string) >> either on client or on server
side. If you want change behavior for specific instance of SOAP::Lite, you
may subclass C<SOAP::Serializer>, override C<as_string()> method that is
responsible for string encoding (take a look into C<as_base64Binary()>) and
specify B<new> serializer class for your SOAP::Lite object with:
my $soap = new SOAP::Lite
serializer => My::Serializer->new,
..... other parameters
or on server side:
my $server = new SOAP::Transport::HTTP::Daemon # or any other server
serializer => My::Serializer->new,
..... other parameters
If you want to change this behavior for B<all> instances of SOAP::Lite, just
substitute C<as_string()> method with C<as_base64Binary()> somewhere in your
code B<after> C<use SOAP::Lite> and B<before> actual processing/sending:
*SOAP::Serializer::as_string = \&SOAP::XMLSchema2001::Serializer::as_base64Binary;
Be warned that last two methods will affect B<all> strings and convert them
into base64 encoded. It doesn't make any difference for SOAP::Lite, but it
B<may> make a difference for other toolkits.
