RT::Client::REST(3) User Contributed Perl Documentation RT::Client::REST(3)NAMERT::Client::REST-- talk to RT installation using REST protocol.
SYNOPSIS
use Error qw(:try);
use RT::Client::REST;
my $rt = RT::Client::REST->new(
server => 'http://example.com/rt',
timeout => 30,
);
try {
$rt->login(username => $user, password => $pass);
} catch Exception::Class::Base with {
die "problem logging in: ", shift->message;
};
try {
# Get ticket #10
$ticket = $rt->show(type => 'ticket', id => 10);
} catch RT::Client::REST::UnauthorizedActionException with {
print "You are not authorized to view ticket #10\n";
} catch RT::Client::REST::Exception with {
# something went wrong.
};
DESCRIPTIONRT::Client::REST is /usr/bin/rt converted to a Perl module. I needed
to implement some RT interactions from my application, but did not feel
that invoking a shell command is appropriate. Thus, I took rt tool,
written by Abhijit Menon-Sen, and converted it to an object-oriented
Perl module.
USAGE NOTES
This API mimics that of 'rt'. For a more OO-style APIs, please use
RT::Client::REST::Object-derived classes: RT::Client::REST::Ticket and
RT::Client::REST::User. not implemented yet).
METHODS
new ()
The constructor can take these options (note that these can also be
called as their own methods):
server
server is a URI pointing to your RT installation.
If you have already authenticated against RT in some other part
of your program, you can use _cookie parameter to supply an
object of type HTTP::Cookies to use for credentials information.
timeout
timeout is the number of seconds HTTP client will wait for the
server to respond. Defaults to LWP::UserAgent's default timeout,
which is 300 seconds.
basic_auth_cb
This callback is to provide the HTTP client (based on
LWP::UserAgent) with username and password for basic
authentication. It takes the same arguments as
"get_basic_credentials()" of LWP::UserAgent and returns username
and password:
$rt->basic_auth_cb( sub {
my ($realm, $uri, $proxy) = @_;
# do some evil things
return ($username, $password);
}
login (username => 'root', password => 'password')
Log in to RT. Throws an exception on error.
Usually, if the other side uses basic HTTP authentication, you do
not have to log in, but rather prodive HTTP username and password
instead. See basic_auth_cb above.
show (type => $type, id => $id)
Return a reference to a hash with key-value pair specifying object
$id of type $type.
edit (type => $type, id => $id, set => { status => 1 })
Set fields specified in parameter set in object $id of type $type.
create (type => $type, set => \%params, text => $text)
Create a new object of type $type and set initial parameters to
%params. For a ticket object, 'text' parameter can be supplied to
set the initial text of the ticket. Returns numeric ID of the new
object. If numeric ID cannot be parsed from the response,
RT::Client::REST::MalformedRTResponseException is thrown.
search (type => $type, query => $query, %opts)
Search for object of type $type by using query $query. For
example:
# Find all stalled tickets
my @ids = $rt->search(
type => 'ticket',
query => "Status = 'stalled'",
);
%opts is a list of key-value pairs:
orderby
The value is the name of the field you want to sort by. Plus
or minus sign in front of it signifies ascending order (plus)
or descending order (minus). For example:
# Get all stalled tickets in reverse order:
my @ids = $rt->search(
type => 'ticket',
query => "Status = 'stalled'",
orderby => '-id',
);
"search" returns the list of numeric IDs of objects that matched
your query. You can then use these to retrieve object information
using "show()" method:
my @ids = $rt->search(
type => 'ticket',
query => "Status = 'stalled'",
);
for my $id (@ids) {
my ($ticket) = $rt->show(type => 'ticket', ids => [$id]);
print "Subject: ", $t->{Subject}, "\n";
}
comment (ticket_id => $id, message => $message, %opts)
Comment on a ticket with ID $id. Optionally takes arguments cc and
bcc which are references to lists of e-mail addresses and
attachments which is a list of filenames to be attached to the
ticket.
$rt->comment(
ticket_id => 5,
message => "Wild thing, you make my heart sing",
cc => [qw(dmitri@localhost some@otherdude.com)],
);
correspond (ticket_id => $id, message => $message, %opts)
Add correspondence to ticket ID $id. Takes optional cc, bcc, and
attachments parameters (see "comment" above).
get_attachment_ids (id => $id)
Get a list of numeric attachment IDs associated with ticket $id.
get_attachment (parent_id => $parent_id, id => $id)
Returns reference to a hash with key-value pair describing
attachment $id of ticket $parent_id. (parent_id because -- who
knows? -- maybe attachments won't be just for tickets anymore in
the future).
get_transaction_ids (parent_id => $id, %opts)
Get a list of numeric IDs associated with parent ID $id. %opts
have the following options:
type
Type of the object transactions are associated wtih. Defaults to
"ticket" (I do not think server-side supports anything else).
This is designed with the eye on the future, as transactions are
not just for tickets, but for other objects as well.
transaction_type
If not specified, IDs of all transactions are returned. If set
to a scalar, only transactions of that type are returned. If you
want to specify more than one type, pass an array reference.
Transactions may be of the following types (case-sensitive):
AddLink
AddWatcher
Comment
Correspond
Create
CustomField
DeleteLink
DelWatcher
EmailRecord
Give
Set
Status
Steal
Take
Told
get_transaction (parent_id => $id, id => $id, %opts)
Get a hashref representation of transaction $id associated with
parent object $id. You can optionally specify parent object type
in %opts (defaults to 'ticket').
merge_tickets (src => $id1, dst => $id2)
Merge ticket $id1 into ticket $id2.
link_tickets (src => $id1, dst => $id2, link_type => $type)
Create a link between two tickets. A link type can be one of the
following:
· DependsOn
· DependedOnBy
· RefersTo
· ReferredToBy
· HasMember
· MemberOf
unlink_tickets (src => $id1, dst => $id2, link_type => $type)
Remove a link between two tickets (see link_tickets())
take (id => $id)
Take ticket $id. This will throw
"RT::Client::REST::AlreadyTicketOwnerException" if you are already
the ticket owner.
untake (id => $id)
Untake ticket $id. This will throw
"RT::Client::REST::AlreadyTicketOwnerException" if Nobody is
already the ticket owner.
steal (id => $id)
Steal ticket $id. This will throw
"RT::Client::REST::AlreadyTicketOwnerException" if you are already
the ticket owner.
EXCEPTIONS
When an error occurs, this module will throw exceptions. I recommend
using Error.pm's try{} mechanism to catch them, but you may also use
simple eval{}. The former will give you flexibility to catch just the
exceptions you want.
Please see RT::Client::REST::Exception for the full listing and
description of all the exceptions.
LIMITATIONS
Beginning with version 0.14, methods "edit()" and "show()" only support
operating on a single object. This is a conscious departure from
semantics offered by the original tool, as I would like to have a
precise behavior for exceptions. If you want to operate on a whole
bunch of objects, please use a loop.
DEPENDENCIES
The following modules are required:
· Error
· Exception::Class
· LWP
· HTTP::Cookies
· HTTP::Request::Common

BUGS
Most likely. Please report.
VARIOUS NOTESRT::Client::REST does not (at the moment, see TODO file) retrieve forms
from RT server, which is either good or bad, depending how you look at
it.
VERSION
This is version 0.37 of RT::Client::REST.
AUTHORS
Original /usr/bin/rt was written by Abhijit Menon-Sen <ams@wiw.org>.

<dams@cpan.org> joined as the project's co-maintainer.
