NAME

Net::OpenID::Yadis - Perform Yadis discovery on URLs 

VERSION

version 1.20 

SYNOPSIS

  use Net::OpenID::Yadis;  my $disc = Net::OpenID::Yadis->new(      consumer => $consumer, # Net::OpenID::Consumer object  );  my $xrd = $disc->discover("http://id.example.com/") or Carp::croak($disc->err);  print $disc->identity_url;       # Yadis URL (Final URL if redirected)  print $disc->xrd_url;            # Yadis Resourse Descriptor URL  foreach my $srv (@$xrd) {        # Loop for Each Service in Yadis Resourse Descriptor    print $srv->priority;          # Service priority (sorted)    print $srv->Type;              # Identifier of some version of some service (scalar, array or array ref)    print $srv->URI;               # URI that resolves to a resource providing the service (scalar, array or array ref)    print $srv->extra_field("Delegate","http://openid.net/xmlns/1.0");                                   # Extra field of some service  }  # If you are interested only in OpenID. (either 1.1 or 2.0)  my $xrd = $self->services(    'http://specs.openid.net/auth/2.0/signon',    'http://specs.openid.net/auth/2.0/server',    'http://openid.net/signon/1.1',  );  # If you want to choose random server by code-ref.  my $xrd = $self->services(sub{($_[int(rand(@_))])});
 

DESCRIPTION

This module provides an implementation of the Yadis protocol, which doesXRDS-based service discovery on URLs.

This module was originally developed by OHTSUKA Ko-hei as Net::Yadis::Discovery,but was forked and simplified for inclusion in the core OpenID Consumer package.

This simplified version is tailored for the needs of Net::OpenID::Consumer; for otheruses, Net::Yadis::Discovery is probably a better choice. 

CONSTRUCTOR

new
my $disc = Net::OpenID::Yadis->new([ %opts ]);

You can set the "consumer" in the constructor. See the correspondingmethod description below.

 

EXPORT

This module exports three constant values to use with discover method.
YR_GET
If you set this, module check Yadis URL start from HTTP GET request. This is the default.
YR_XRDS
If you set this, this module consider Yadis URL as Yadis Resource Descriptor URL.If not so, an error is returned.
 

METHODS

$disc->consumer($consumer)
$disc->consumer
Get or set the Net::OpenID::Consumer object that this object is associated with.
$disc->discover($url,[$request_method])
Given a user-entered $url (which could be missing http://, or haveextra whitespace, etc), returns either array/array ref of Net::OpenID::Yadis::Serviceobjects, or undef on failure.

$request_method is optional, and if set this, you can change the HTTPrequest method of fetching Yadis URL.See EXPORT to know the value you can set, and default is YR_HEAD.

If this method returns undef, you can rely on the following errorscodes (from $csr->errcode) to decide what to present to the user:

xrd_parse_error
xrd_format_error
too_many_hops
no_yadis_document
url_fetch_err
empty_url
url_gone
$disc->xrd_objects
Returns array/array ref of Net::OpenID::Yadis objects.It is same what could be got by discover method.
$disc->identity_url
Returns Yadis URL.If not redirected, it is same with the argument of discover method.
$disc->xrd_url
Returns Yadis Resource Descriptor URL.
$disc->servers($protocol,$protocol,...)
$disc->servers($protocol=>[$version1,$version2],...)
$disc->servers($protocol,....,$code_ref);
Filter method of xrd_objects.

If no option is defined, returns same result with xrd_objects method.

protocol names or Type URLs are given, filter only given protocol.Two or more protocols are given, return and results of filtering.

Sample:
  $disc->servers(``openid'',``http://lid.netmesh.org/sso/1.0'');

If reference of version numbers array is given after protocol names,filter only given version of protocol.

Sample:
  $disc->servers(``openid''=>['1.0','1.1'],``lid''=>['1.0']);

If you want to use version numbers limitation with type URL, you can use\ver as place holder of version number.

Sample:
  $disc->servers(``http://lid.netmesh.org/sso/\ver''=>['1.0','2.0']);

If code reference is given as argument , you can make your own filter rule.code reference is executed at the last of filtering logic, like this:

  @results = $code_ref->(@temporary_results)

Sample: If you want to filter OpenID server and get only first one:
  ($openid_server) = $disc->servers(``openid'',sub{$_[0]});

$disc->err
Returns the last error, in form ``errcode: errtext''
$disc->errcode
Returns the last error code.
$disc->errtext
Returns the last error text.
