NAME

       RT::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.
         };

DESCRIPTION

       RT::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 180 seconds (please check LWP::UserAgent's documentation
             for accurate timeout information).

           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);
               }

           logger
             A  logger object.  It should be able to debug(), info(), warn() and error().  It is not widely used
             in the code (yet), and so it is mostly useful for development.

       login (username => 'root', password => 'password') =item login (my_userfield => 'root', my_passfield =>
       '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. The keys are
           the names of RT's fields. Keys for custom fields are in the form of "CF.{CUST_FIELD_NAME}".

       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', id => $id);
               print "Subject: ", $ticket->{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, undecoded => $bool)
           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).

           If  the  option  undecoded  is  set  to  a  true  value, the attachment will be returned verbatim and
           undecoded (this is probably what you want with images and binary data).

       get_links (type => $type, id => $id)
           Get link information for object of type $type whose id is $id.  If type is not specified, 'ticket' is
           used.

       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

SEE ALSO

       LWP::UserAgent, RT::Client::REST::Exception

BUGS

       Most likely.  Please report.

VARIOUS NOTES

       RT::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.
