NAME

JIRA::REST - A thin wrapper around JIRA's REST API

VERSION

version 0.002

SYNOPSIS

use JIRA::REST;

my $jira = JIRA::REST->new('https://jira.example.net', 'myuser', 'mypass');

# Cache some JIRA objects
my %issuetypes = {map {($_->{name} => $_)} @{$jira->GET('/issuetype')}};
my %priorities = {map {($_->{name} => $_)} @{$jira->GET('/priority' )}};
my %projects   = {map {($_->{name} => $_)} @{$jira->GET('/project'  )}};

# A handy routine to construct id hashes
sub id_of { return { id => $_[0]->{id} }; };

# Cache information about a project
my $project    = $projects{'My Project'}->{id};
my %components = {map {($_->{name} => $_)} @{$jira->GET("/project/$pid/components")}};

# File a bug
my $issue = $jira->POST('/issue', undef, {
    fields => {
        project   => id_of($projects{'My Project'}),
        issuetype => id_of($issuetypes{Bug}),
        summary   => 'Cannot login',
        priority  => id_of($priorities{Major}),
        versions  => [ id_of($components{auth_module}) ],
        description => 'Bla bla bla',
    },
});

# Get issue
$issue = $jira->GET("/issue/TST-101");

# Iterate on issues
my $search = $jira->POST('/search', undef, {
    jql        => 'project = "TST" and status = "open"',
    startAt    => 0,
    maxResults => 16,
    fields     => [ qw/summary status assignee/ ],
});

foreach my $issue (@{$search->{issues}}) {
    print "Found issue $issue->{key}\n";
}

DESCRIPTION

JIRA is a proprietary bug tracking system from Atlassian.

This module implements a very thin wrapper around JIRA's REST API which is superseding it's old SOAP API for which there is another Perl module called JIRA::Client.

CONSTRUCTOR

new URL, USERNAME, PASSWORD [, REST_CLIENT_CONFIG]

The constructor needs up to four arguments:

  • URL

    A string or a URI object denoting the base URL of the JIRA server. This is a required argument.

    You may choose a specific API version by appending the /rest/api/VERSION string to the URL's path. It's more common to left it unspecified, in which case the /rest/api/latest string is appended automatically to the URL.

  • USERNAME

    The username of a JIRA user.

    It can be undefined if PASSWORD is also undefined. In such a case the user credentials are looked up in the .netrc file.

  • PASSWORD

    The HTTP password of the user. (This is the password the user uses to log in to JIRA's web interface.)

    It can be undefined, in which case the user credentials are looked up in the .netrc file.

  • REST_CLIENT_CONFIG

    A JIRA::REST object uses a REST::Client object to make the REST invocations. This optional argument must be a hash-ref that can be fed to the REST::Client constructor. Note that the URL argument overwrites any value associated with the host key in this hash.

METHODS

JIRA's REST API documentation lists dozens of "resources" which can be operated via the standard HTTP requests: GET, DELETE, PUT, and POST. JIRA::REST objects implement four methods called GET, DELETE, PUT, and POST to make it easier to invoke and get results from JIRA's REST endpoints.

All four methods need two arguments:

  • RESOURCE

    This is the resource's 'path', minus the API version prefix. For example, in order to GET the list of all fields, you must pass simply /field, not /rest/api/latest/field, and in order to get a list of all the components of a project, you must pass simply /project/$key/components, not /rest/api/latest/project/$key/components.

    This argument is required.

  • QUERY

    Some resource methods require or admit parameters which are passed as a query-string appended to the resource's path. You may construct the query string and append it to the RESOURCE argument yourself, but it's easier and safer to pass the arguments in a hash. This way the query string is constructed for you and its values are properly percent-encoded to avoid errors.

    This argument is optional for GET and DELETE. For PUT and POST it must be passed explicitly as undef if not needed.

The PUT and POST methods accept two more arguments:

  • VALUE

    This is the "entity" being PUT or POSTed. It can be any value, but usually is a hash-ref. The value is encoded as a JSON string using the JSON::encode method and sent with a Content-Type of application/json.

    It's usually easy to infer from the JIRA REST API documentation which kind of value you should pass to each resource.

    This argument is required.

  • HEADERS

    This optional argument allows you to specify extra HTTP headers that should be sent with the request. Each header is specified as a key/value pair in a hash.

All four methods return the value returned by the associated resource's method, as specified in the documentation, decoded according to its content type as follows:

  • application/json

    The majority of the API's resources return JSON values. Those are decoded using the decode method of a JSON object. Most of the endpoints return hashes, which are returned as a Perl hash-ref.

  • text/plain

    Those values are returned as simple strings.

Some endpoints don't return anything. In those cases, the methods return undef. The methods croak if they get any other type of values in return.

In case of errors (i.e., if the underlying HTTP method return an error code different from 2xx) the methods croak with a multi-line string like this:

ERROR: <CODE> - <MESSAGE>
<CONTENT-TYPE>
<CONTENT>

So, in order to treat errors you must invoke the methods in an eval block or use any of the exception handling Perl modules, such as Try::Tiny and Try::Catch.

GET RESOURCE [, QUERY]

Returns the RESOURCE as a Perl data structure.

DELETE RESOURCE [, QUERY]

Deletes the RESOURCE.

PUT RESOURCE, QUERY, VALUE [, HEADERS]

Creates RESOURCE based on VALUE.

POST RESOURCE, QUERY, VALUE [, HEADERS]

Updates RESOURCE based on VALUE.

SEE ALSO

  • REST::Client

    JIRA::REST uses a REST::Client object to perform the low-level interactions.

  • JIRA::Client

    JIRA::Client is another Perl module implementing the other JIRA API based on SOAP.

  • JIRA::Client::REST

    This is another module implementing JIRA's REST API using SPORE. I got a message from the author saying that he doesn't intend to keep it going.
