SYNOPSIS

    use utf8;

DESCRIPTION

AnyEvent::Twitter is a very thin wrapper for Twitter API using OAuth.

API VERSION

As of version 0.63, AnyEvent::Twitter supports Twitter REST API v1.1.

NOTE: API version 1.0 is already deprecated.

METHODS

new

All arguments are required except api_version. If you don't know how to obtain these parameters, take a look at eg/gen_token.pl and run it.

consumer_key

consumer_secret

access_token (or token)

access_token_secret (or token_secret)

api_version (optional; default: 1.1)

If you have a problem with API changes, specify api_version parameter. Possible values are: 1.1 or 1.0

get

$ua->get($api, sub {})

$ua->get($api, \%params, sub {})

$ua->get($url, sub {})

$ua->get($url, \%params, sub {})

post

$ua->post($api, \%params, sub {})

$ua->post($url, \%params, sub {})

$ua->post($api, \@params, sub {})

$ua->post($url, \@params, sub {})

UPLOADING MEDIA FILE

You can use statuses/update_with_media API to upload photos by specifying parameters as arrayref like below example.

Uploading photos will be tranferred with Content-Type multipart/form-data (not application/x-www-form-urlencoded)

    use utf8;
    $ua->post(
        'statuses/update_with_media',
        [
            status    => '桜',
            'media[]' => [ undef, $filename, Content => $loaded_image_binary ],
        ],
        sub {
            my ($hdr, $res, $reason) = @_;
            say $res->{user}{screen_name};
        }
    );

request

These parameters are required.

api or url

The api parameter is a shortcut option.

If you want to specify the API url, the url parameter is good for you. The format should be 'json'.

The api parameter will be internally processed as:

    sprintf 'https://api.twitter.com/1.1/%s.json', $api; # version 1.1
    sprintf 'http://api.twitter.com/1/%s.json',    $api; # version 1.0

You can find available apis at API Documentation

method and params

Investigate the HTTP method and required parameters of Twitter API that you want to use. Then specify it. GET and POST methods are allowed. You can omit params if Twitter API doesn't require it.

callback

This module is AnyEvent::HTTP style, so you have to pass the callback (coderef).

Passed callback will be called with $header, $response, $reason and $error_response. If something is wrong with the response from Twitter API, $response will be undef. On non-2xx HTTP status code, you can get the decoded response via $error_response. So you can check the value like below.

    my $callback = sub {
        my ($header, $response, $reason, $error_response) = @_;

        if ($response) {
            say $response->{screen_name};
        } else {
            say $reason;
            for my $error (@{$error_response->{errors}}) {
                say "$error->{code}: $error->{message}";
            }
        }
    };

parse_timestamp

parse_timestamp parses created_at timestamp like "Thu Mar 01 17:38:56 +0000 2012". It returns Time::Piece object. Its timezone is localtime.

AnyEvent::Twitter->parse_timestamp($created_at)

TESTS

Most of all tests are written as author tests since this module depends on remote API server. So if you want read code that works well, take a look at xt/ directory.

EXPERIMENTAL METHODS

Methods listed below are experimental feature. So interfaces or returned values may vary in the future.

AnyEvent::Twitter->get_request_token

    AnyEvent::Twitter->get_request_token(
        consumer_key    => $consumer_key,
        consumer_secret => $consumer_secret,
        callback_url    => 'http://example.com/callback',
        # auth => 'authenticate',
        cb => sub {
            my ($location, $response, $body, $header) = @_;
            # $location is the endpoint where users are asked the permission
            # $response is a hashref of parsed body
            # $body is raw response itself
            # $header is response headers
        },
    );

AnyEvent::Twitter->get_access_token

    AnyEvent::Twitter->get_access_token(
        consumer_key       => $consumer_key,
        consumer_secret    => $consumer_secret,
        oauth_token        => $oauth_token,
        oauth_token_secret => $oauth_token_secret,
        oauth_verifier     => $oauth_verifier,
        cb => sub {
            my ($token, $body, $header) = @_;
            # $token is the parsed body
            # $body is raw response
            # $header is response headers
        },
    );
