NAME
API::Trello - Perl 5 API wrapper for Trello
VERSION
version 0.01
SYNOPSIS
use API::Trello;
my $trello = API::Trello->new(
key => 'KEY',
token => 'TOKEN',
identifier => 'APPLICATION (yourname@example.com)',
);
my $board = $trello->boards(1);
my $results = $board->fetch;
# after some introspection
$board->delete;DESCRIPTION
This distribution provides an object-oriented thin-client library for interacting with the Trello (http://trello.com) API. For usage and documentation information visit https://trello.com/docs/gettingstarted/index.html.
THIN CLIENT
A thin-client library is advantageous as it has complete coverage and can easily adapt to changes in the API with minimal effort. As a thin-client library, this module does not map specific HTTP requests to specific routines nor does it provide parameter validation, pagination, or other conventions found in typical API client implementations, instead, it simply provides a simple and consistent mechanism for dynamically generating HTTP requests. Additionally, this module has support for debugging and retrying API calls as well as throwing exceptions when 4xx and 5xx server response codes are received.
Building
my $board = $trello->boards(1);
my $checklists = $board->checklists;
$checklists->action; # GET /boards/1/checklists
$checklists->action('head'); # HEAD /boards/1/checklistsBuilding up an HTTP request object is extremely easy, simply call method names which correspond to the API's path segments in the resource you wish to execute a request against. This module uses autoloading and returns a new instance with each method call. The following is the equivalent:
my $board = $trello->resource(boards => 1);
my $checklists = $board->resource('checklists');
# or
my $checklists = $trello->resource('boards', 1, 'checklists');
# then
$checklists->action('put', %args); # PUT /boards/1/checklistsBecause each call returns a new API instance configured with a resource locator based on the supplied parameters, reuse and request isolation are made simple, i.e., you will only need to configure the client once in your application.
Fetching
my $boards = $trello->boards;
$boards->fetch(
query => {
# query-string parameters
},
);
# equivalent to
$trello->resource('boards')->action(
get => ( query => { ... } )
);This example illustrates how you might fetch an API resource.
Creating
my $boards = $trello->boards;
$boards->create(
data => {
# content-body parameters
},
query => {
# query-string parameters
},
);
# or
my $boards = $trello->boards->create(...);
# equivalent to
$trello->resource('boards')->action(
post => ( query => { ... }, data => { ... } )
);This example illustrates how you might create a new API resource.
Updating
my $boards = $trello->boards;
my $board = $boards->resource(1);
$board->update(
data => {
# content-body parameters
},
query => {
# query-string parameters
},
);
# or
my $board = $trello->boards(1);
$board->update(...);
# equivalent to
$trello->resource('boards')->action(
put => ( query => { ... }, data => { ... } )
);This example illustrates how you might update an new API resource.
Deleting
my $boards = $trello->boards;
my $board = $boards->resource(1);
$board->delete(
data => {
# content-body parameters
},
query => {
# query-string parameters
},
);
# or
my $board = $trello->boards(1);
$board->delete(...);
# equivalent to
$trello->resource('boards')->action(
delete => ( query => { ... }, data => { ... } )
);This example illustrates how you might delete an API resource.
Transacting
my $board = $trello->resource('boards', '1');
my ($results, $transaction) = $board->fetch(...);This example illustrates how you can access the transaction object used to submit the HTTP request.
PARAMETERS
key
$trello->key;
$trello->key('KEY');The key parameter should be set to the account holder's API key.
token
$trello->token;
$trello->token('TOKEN');The token parameter should be set to the account holder's API access token.
identifier
$trello->identifier;
$trello->identifier('IDENTIFIER');The identifier parameter should be set using a string to identify your app.
ATTRIBUTES
debug
$trello->debug;
$trello->debug(1);The debug attribute if true prints HTTP requests and responses to standard out.
fatal
$trello->fatal;
$trello->fatal(1);The fatal attribute if true promotes 4xx and 5xx server response codes to exceptions, a API::Trello::Exception object.
retries
$trello->retries;
$trello->retries(10);The retries attribute determines how many times an HTTP request should be retried if a 4xx or 5xx response is received. This attribute defaults to 0.
timeout
$trello->timeout;
$trello->timeout(5);The timeout attribute determines how long an HTTP connection should be kept alive. This attribute defaults to 10.
url
$trello->url;
$trello->url(Mojo::URL->new('https://api.trello.com'));The url attribute set the base/pre-configured URL object that will be used in all HTTP requests. This attribute expects a Mojo::URL object.
user_agent
$trello->user_agent;
$trello->user_agent(Mojo::UserAgent->new);The user_agent attribute set the pre-configured UserAgent object that will be used in all HTTP requests. This attribute expects a Mojo::UserAgent object.
METHODS
action

# e.g.
$trello->action('head', %args); # HEAD request
$trello->action('optons', %args); # OPTIONS request
