NAME

WWW::Shorten::Bitly - Interface to shortening URLs using http://bitly.com

SYNOPSIS

The traditional way, using the WWW::Shorten interface:

    use strict;
    use warnings;

    use WWW::Shorten::Bitly;
    # use WWW::Shorten 'Bitly';  # or, this way

    # if you have a config file with your credentials:
    my $short_url = makeashorterlink('http://www.foo.com/some/long/url');
    my $long_url  = makealongerlink($short_url);

    # otherwise
    my $short = makeashorterlink('http://www.foo.com/some/long/url', {
        username => 'username',
        password => 'password',
        ...
    });

Or, the Object-Oriented way:

    use strict;
    use warnings;
    use Data::Dumper;
    use Try::Tiny qw(try catch);
    use WWW::Shorten::Bitly;

    my $bitly = WWW::Shorten::Bitly->new(
        username => 'username',
        password => 'password',
        client_id => 'adflkdgalgka',
        client_secret => 'sldfkjasdflg',
    );

    try {
        my $res = $bitly->shorten(longUrl => 'http://google.com/');
        say Dumper $res;
        # {
        #   global_hash => "900913",
        #   hash => "ze6poY",
        #   long_url => "http://google.com/",
        #   new_hash => 0,
        #   url => "http://bit.ly/ze6poY"
        # }
    }
    catch {
        die("Oh, no! $_");
    };

DESCRIPTION

A Perl interface to the Bitly.com API.

You can either use the traditional (non-OO) interface provided by WWW::Shorten. Or, you can use the OO interface that provides you with more functionality.

FUNCTIONS

In the non-OO form, WWW::Shorten::Bitly makes the following functions available.

    my $short_url = makeashorterlink('https://some_long_link.com');
    # OR
    my $short_url = makeashorterlink('https://some_long_link.com', {
        username => 'foo',
        password => 'bar',
        # any other attribute can be set as well.
    });

The function makeashorterlink will call the http://bitly.com web site, passing it your long URL and will return the shorter version.

http://bitly.com requires the use of a user id and API key to shorten links.

    my $long_url = makealongerlink('http://bit.ly/ze6poY');
    # OR
    my $long_url = makealongerlink('http://bit.ly/ze6poY', {
        username => 'foo',
        password => 'bar',
        # any other attribute can be set as well.
    });

The function makealongerlink does the reverse. makealongerlink will accept as an argument either the full URL or just the identifier.

If anything goes wrong, either function will die.

ATTRIBUTES

In the OO form, each WWW::Shorten::Bitly instance makes the following attributes available. Please note that changing any attribute will unset the "access_token" in WWW::Shorten::Bitly attribute and effectively log you out.

access_token

    my $token = $bitly->access_token;
    $bitly = $bitly->access_token('some_access_token'); # method chaining

Gets or sets the access_token. If the token is set, then we won't try to login. You can set this ahead of time if you like, or it will be set on the first method call or on "login" in WWW::Shorten::Bitly.

client_id

    my $id = $bitly->client_id;
    $bitly = $bitly->client_id('some_client_id'); # method chaining

Gets or sets the client_id. This is used in the Resource Owner Credentials Grants login method along with the "client_secret" in WWW::Shorten::Bitly attribute.

client_secret

    my $secret = $bitly->client_secret;
    $bitly = $bitly->client_secret('some_secret'); # method chaining

Gets or sets the client_secret. This is used in the Resource Owner Credentials Grants login method along with the "client_id" in WWW::Shorten::Bitly attribute.

password

    my $password = $bitly->password;
    $bitly = $bitly->password('some_secret'); # method chaining

Gets or sets the password. This is used in both the Resource Owner Credentials Grants and the HTTP Basic Authentication login methods.

username

    my $username = $bitly->username;
    $bitly = $bitly->username('my_username'); # method chaining

Gets or sets the username. This is used in both the Resource Owner Credentials Grants and the HTTP Basic Authentication login methods.

METHODS

In the OO form, WWW::Shorten::Bitly makes the following methods available.

new

    my $bitly = WWW::Shorten::Bitly->new(
        access_token => 'sometokenIalreadyreceived24123123512451',
        client_id => 'some id here',
        client_secret => 'some super secret thing',
        password => 'my password',
        username => 'my_username@foobar.com'
    );

The constructor can take any of the attributes above as parameters. If you've logged in using some other form (OAuth2, etc.) then all you need to do is provide the access_token.

Any or all of the attributes can be set in your configuration file. If you have a configuration file and you pass parameters to new, the parameters passed in will take precedence.

bitly_pro_domain

    my $bpd = $bitly->bitly_pro_domain(domain => 'http://nyti.ms');
    say Dumper $bpd;

    my $bpd2 = $bitly->bitly_pro_domain(domain => 'http://example.com');
    say Dumper $bpd2;

Query whether a given domain is a valid Bitly pro domain. Returns a hash reference with the information or dies on error.

clicks

    my $clicks = $bitly->clicks(
        link => "http://bit.ly/1RmnUT",
        unit => 'day',
        units => -1,
        timezone => 'America/New_York',
        rollup => 'false', # or 'true'
        limit => 100, # from 1 to 1000
        unit_reference_ts => 'now', # epoch timestamp
    );
    say Dumper $clicks;

Get the number of clicks on a single link. Returns a hash reference of information or dies.

clicks_by_day

    my $clicks = $bitly->clicks_by_day(
        link => "http://bit.ly/1RmnUT",
        timezone => 'America/New_York',
        rollup => 'false', # or 'true'
        limit => 100, # from 1 to 1000
        unit_reference_ts => 'now', # epoch timestamp
    );
    say Dumper $clicks;

This call used to exist, but now is merely an alias to the "clicks" in WWW::Shorten::Bitly method that hard-sets the unit to 'day' and the units to 7. Returns a hash reference of information or dies.

countries

    my $countries = $bitly->countries(
        unit => 'day',
        units => -1,
        timezone => 'America/New_York',
        rollup => 'false', # or 'true'
        limit => 100, # from 1 to 1000
        unit_reference_ts => 'now', # epoch timestamp
    );
    say Dumper $countries;

Returns a hash reference of aggregate metrics about the countries referring click traffic to all of the authenticated user's links. Dies on failure.

expand

    my $long = $bitly->expand(
        shortUrl => "http://bit.ly/1RmnUT", # OR
        hash => '1RmnUT', # or: 'custom-name'
    );
    say $long->{long_url};

Expand a URL using https://dev.bitly.com/links.html#v3_expand. Older versions of this library required you to pass a URL parameter. That parameter has been aliased for your convenience. However, we urge you to stick with the parameters in the API. Returns a hash reference or dies.

info

    my $info = $bitly->info(
        shortUrl => 'http://bitly.com/jmv6', # OR
        hash => 'jmv6',
        expand_user => 'false', # or 'true'
    );
    say Dumper $info;

Get info about a shorter URL using the info method call. This will return a hash reference full of information about the given short URL or hash. It will die on failure.

login

    use Try::Tiny qw(try catch);

    try {
        $bitly->login();
        say "yay, logged in!";
    }
    catch {
        warn "Crap! Our login failed! $_";
    };

This method will just return your object instance if your access_token is already set. Otherwise, it will make use of one of the two login methods depending on how much information you've supplied. On success, the access_token attribute will be set and your instance will be returned (method-chaining). On failure, an exception with relevant information will be thrown.

If you would prefer, you can use one of the other two forms of logging in:

These two forms require at least the username and password parameters.

lookup

    my $info = $bitly->lookup(url => "http://www.google.com/");
    say $info;

Use this lookup method call to query for a short URL based on a long URL. Returns a hash reference or dies.

referrers

    my $refs = $bitly->referrers(
        link => "http://bit.ly/1RmnUT",
        unit => 'day',
        units => -1,
        timezone => 'America/New_York',
        rollup => 'false', # or 'true'
        limit => 100, # from 1 to 1000
        unit_reference_ts => 'now', # epoch timestamp
    );
    say Dumper $refs;

Use the referrers API call to get metrics about the pages referring click traffic to a single short URL. Returns a hash reference or dies.

shorten

    my $short = $bitly->shorten(
        longUrl => "http://www.example.com", # required.
        domain => 'bit.ly', # or: 'j.mp' or 'bitly.com'
    );
    say $short->{url};

Shorten a URL using https://dev.bitly.com/links.html#v3_shorten. Older versions of this library required you to pass a URL parameter. That parameter has been aliased for your convenience. However, we urge you to stick with the parameters in the API. Returns a hash reference or dies.

CONFIG FILES

$HOME/.bitly or _bitly on Windows Systems.

    username=username
    password=some_password_here
    client_id=foobarbaz
    client_secret=asdlfkjadslkgj34t34talkgjag

Set any or all "ATTRIBUTES" in WWW::Shorten::Bitly in your config file in your home directory. Each key=val setting should be on its own line. If any parameters are then passed to the "new" in WWW::Shorten::Bitly constructor, those parameter values will take precedence over these.
