UDDI(3)
NAME
UDDI::Lite - Library for UDDI clients in Perl
SYNOPSIS
use UDDI::Lite;
print UDDI::Lite
-> proxy('http://uddi.microsoft.com/inquire')
-> find_business(name => 'old')
-> result
-> businessInfos->businessInfo->serviceInfos->serviceInfo->name;
The same code with autodispatch:
use UDDI::Lite +autodispatch =>
proxy => 'http://uddi.microsoft.com/inquire'
;
print find_business(name => 'old')
-> businessInfos->businessInfo->serviceInfos->serviceInfo->name;
Or with importing:
use UDDI::Lite
'UDDI::Lite' => [':inquiry'],
proxy => 'http://uddi.microsoft.com/inquire'
;
print find_business(name => 'old')
-> businessInfos->businessInfo->serviceInfos->serviceInfo->name;
Publishing API:
use UDDI::Lite
import => ['UDDI::Data'],
import => ['UDDI::Lite'],
proxy => "https://some.server.com/endpoint_fot_publishing_API";
my $auth = get_authToken({userID => 'USERID', cred => 'CRED'})->authInfo;
my $busent = with businessEntity =>
name("Contoso Manufacturing"),
description("We make components for business"),
businessKey(''),
businessServices with businessService =>
name("Buy components"),
description("Bindings for buying our components"),
serviceKey(''),
bindingTemplates with bindingTemplate =>
description("BASDA invoices over HTTP post"),
accessPoint('http://www.contoso.com/buy.asp'),
bindingKey(''),
tModelInstanceDetails with tModelInstanceInfo =>
description('some tModel'),
tModelKey('UUID:C1ACF26D-9672-4404-9D70-39B756E62AB4')
;
print save_business($auth, $busent)->businessEntity->businessKey;
DESCRIPTION
UDDI::Lite for Perl is a collection of Perl modules which provides a
simple and lightweight interface to the Universal Description, Discov-
ery and Integration (UDDI) server.
To learn more about UDDI, visit http://www.uddi.org/.
The main features of the library are:
o Supports both inquiry and publishing API
o Builded on top of SOAP::Lite module, hence inherited syntax and fea-
tures
o Supports easy-to-use interface with convinient access to (sub)ele-
ments and attributes
o Supports HTTPS protocol
o Supports SMTP protocol
o Supports Basic/Digest server authentication
OVERVIEW OF CLASSES AND PACKAGES
This table should give you a quick overview of the classes provided by
the library.
UDDI::Lite.pm
-- UDDI::Lite -- Main class provides all logic
-- UDDI::Data -- Provides extensions for serialization architecture
-- UDDI::Serializer -- Serializes data structures to UDDI/SOAP package
-- UDDI::Deserializer -- Deserializes result into objects
-- UDDI::SOM -- Provides access to deserialized object tree
UDDI::Lite
All methods that UDDI::Lite gives you access to can be used for both
setting and retrieving values. If you provide no parameters, you'll get
current value, and if you'll provide parameter(s), new value will be
assigned and method will return object (if not stated something else).
This is suitable for stacking these calls like:
$uddi = UDDI::Lite
-> on_debug(sub{print@_})
-> proxy('http://uddi.microsoft.com/inquire')
;
Order is insignificant and you may call new() method first. If you
don't do it, UDDI::Lite will do it for you. However, new() method gives
you additional syntax:
$uddi = new UDDI::Lite
on_debug => sub {print@_},
proxy => 'http://uddi.microsoft.com/inquire'
;
new() accepts hash with method names and values, and will call appro-
priate method with passed value.
Since new() is optional it won't be mentioned anymore.
Other available methods inherited from SOAP::Lite and most usable are:
proxy()
Shortcut for "transport->proxy()". This lets you specify an end-
point and also loads the required module at the same time. It is
required for dispatching SOAP calls. The name of the module will be
defined depending on the protocol specific for the endpoint.
SOAP::Lite will do the rest work.
on_fault()
Lets you specify handler for on_fault event. Default behavior is
die on transport error and does nothing on others. You can change
this behavior globally or locally, for particular object.
on_debug()
Lets you specify handler for on_debug event. Default behavior is do
nothing. Use +trace/+debug option for UDDI::Lite instead.
To change to UDDI Version 2, use the following pragma:
use UDDI::Lite uddiversion => 2;
UDDI::Data
You can use this class if you want to specify value and name for UDDI
elements. For example, "UDDI::Data->name('businessInfo')->value(123)"
will be serialized to "<businessInfo>123</businessInfo>", as well as
"UDDI::Data-"name(businessInfo => 123)>.
If you want to provide names for your parameters you can either specify
find_business(name => 'old')
or do it with UDDI::Data:
find_business(UDDI::Data->name(name => 'old'))
Later has some advantages: it'll work on any level, so you can do:
find_business(UDDI::Data->name(name => UDDI::Data->name(subname => 'old')))
and also you can create arrays with this syntax:
find_business(UDDI::Data->name(name =>
[UDDI::Data->name(subname1 => 'name1'),
UDDI::Data->name(subname2 => 'name2')]))
will be serialized into:
<find_business xmlns="urn:uddi-org:api" generic="1.0">
<name>
<subname1>name1</subname1>
<subname2>name2</subname2>
</name>
</find_business>
For standard elements more convinient syntax is available:
find_business(
findQualifiers(findQualifier('sortByNameAsc',
'caseSensitiveMatch')),
name('M')
)
and
find_business(
findQualifiers([findQualifier('sortByNameAsc'),
findQualifier('caseSensitiveMatch')]),
name('M')
)
both will generate:
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<find_business xmlns="urn:uddi-org:api" generic="1.0">
<findQualifiers>
<findQualifier>sortByNameAsc</findQualifier>
<findQualifier>caseSensitiveMatch</findQualifier>
</findQualifiers>
<name>M</name>
</find_business>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
You can use ANY valid combinations (according to "UDDI Programmer's API
Specification"). If you try to generate something unusual, like
"name(name('myname'))", you'll get:
Don't know what to do with 'name' and 'name' elements ....
If you REALLY need to do it, use "UDDI::Data" syntax described above.
As special case you can pass hash as the first parameter of method call
and values of this hash will be added as attributes to top element:
find_business({maxRows => 10}, UDDI::Data->name(name => old))
gives you
<find_business xmlns="urn:uddi-org:api" generic="1.0" maxRows="10">
....
</find_business>
You can also pass back parameters exactly as you get it from method
call (like you probably want to do with authInfo).
You can get access to attributes and elements through the same inter-
face:
my $list = find_business(name => old);
my $bis = $list->businessInfos;
for ($bis->businessInfo) {
my $s = $_->serviceInfos->serviceInfo;
print $s->name, # element
$s->businessKey, # attribute
"\n";
}
To match advantages provided by "with" operator available in other lan-
guages (like VB) we provide similar functionality that adds you flexi-
bility:
with findQualifiers =>
findQualifier => 'sortByNameAsc',
findQualifier => 'caseSensitiveMatch'
is the same as:
with(findQualifiers =>
findQualifier('sortByNameAsc'),
findQualifier('caseSensitiveMatch'),
)
and:
findQualifiers->with(
findQualifier('sortByNameAsc'),
findQualifier('caseSensitiveMatch'),
)
will all generate the same code as mentioned above:
findQualifiers(findQualifier('sortByNameAsc',
'caseSensitiveMatch')),
Advantage of "with" syntax is the you can specify both attributes and
elements through the same interface. First argument is element where
all other elements and attributes will be attached. Provided examples
and tests cover different syntaxes.
AUTODISPATCHING
UDDI::Lite provides autodispatching feature that lets you create code
that looks similar for local and remote access.
For example:
use UDDI::Lite +autodispatch =>
proxy => 'http://uddi.microsoft.com/inquire';
tells autodispatch all UDDI calls to
'http://uddi.microsoft.com/inquire'. All subsequent calls can look
like:
find_business(name => 'old');
find_business(UDDI::Data->name(name => 'old'));
find_business(name('old'));
BUGS AND LIMITATIONS
o Interface is still subject to change.
o Though HTTPS/SSL is supported you should specify it yourself (with
"proxy" or "endpoint") for publishing API calls.
AVAILABILITY
For now UDDI::Lite is distributed as part of SOAP::Lite package. You
can download it from ( http://soaplite.com/ ) or from CPAN (
http://search.cpan.org/search?dist=SOAP-Lite ).
