NAME ^

WWW::Netflix::API - Interface for Netflix's API

VERSION ^

Version 0.10

OVERVIEW ^

This module is to provide your perl applications with easy access to the Netflix API (http://developer.netflix.com/). The Netflix API allows access to movie and user information, including queues, rating, rental history, and more.

SYNOPSIS ^

  use WWW::Netflix::API;
  use XML::Simple;
  use Data::Dumper;

  my %auth = Your::Custom::getAuthFromCache();
  # consumer key/secret values below are fake
  my $netflix = WWW::Netflix::API->new({
        consumer_key    => '4958gj86hj6g99',
        consumer_secret => 'QWEas1zxcv',
        access_token    => $auth{access_token},
        access_secret   => $auth{access_secret},
        user_id         => $auth{user_id},

        content_filter => sub { use XML::Simple; XMLin(@_) },  # optional
  });
  if( ! $auth{user_id} ){
    my ( $user, $pass ) = .... ;
    @auth{qw/access_token access_secret user_id/} = $netflix->RequestAccess( $user, $pass );
    Your::Custom::storeAuthInCache( %auth );
  }

  $netflix->REST->Users->Feeds;
  $netflix->Get() or die $netflix->content_error;
  print Dumper $netflix->content;

  $netflix->REST->Catalog->Titles->Movies('18704531');
  $netflix->Get() or die $netflix->content_error;
  print Dumper $netflix->content;

And for resources that do not require a netflix account:

  use WWW::Netflix::API;
  use XML::Simple;
  my $netflix = WWW::Netflix::API->new({
        consumer_key
        consumer_secret
        content_filter => sub { XMLin(@_) },
  });
  $netflix->REST->Catalog->Titles;
  $netflix->Get( term => 'zzyzx' );
  printf "%d Results.\n", $netflix->content->{number_of_results};
  printf "Title: %s\n", $_->{title}->{regular} for values %{ $netflix->content->{catalog_title} };


  # Retrieve entire catalog:
  $netflix->content_filter('catalog.xml');
  $netflix->REST->Catalog->Titles->Index;
  $netflix->Get();

GETTING STARTED ^

The first step to using this module is to register at http://developer.netflix.com -- you will need to register your application, for which you'll receive a consumer_key and consumer_secret keypair.

Any applications written with the Netflix API must adhere to the Terms of Use (http://developer.netflix.com/page/Api_terms_of_use) and Branding Requirements (http://developer.netflix.com/docs/Branding).

Usage

This module provides access to the REST API via perl syntactical sugar. For example, to find a user's queue, the REST url is of the form users/userID/feeds :

  http://api.netflix.com/users/T1tareQFowlmc8aiTEXBcQ5aed9h_Z8zdmSX1SnrKoOCA-/queues/disc

Using this module, the syntax would be (note that the Post or Delete methods can be used instead of Get, depending upon the API action being taken):

  $netflix->REST->Users->Queues->Disc;
  $netflix->Get(%$params) or die $netflix->content_error;
  print $netflix->content;

Other examples include:

  $netflix->REST->Users;
  $netflix->REST->Users->At_Home;
  $netflix->REST->Catalog->Titles->Movies('18704531');
  $netflix->REST->Users->Feeds;
  $netflix->REST->Users->Rental_History;

All of the possibilities (and parameter details) are outlined here: http://developer.netflix.com/docs/REST_API_Reference

There is a helper method "rest2sugar" included that will provide the proper syntax given a url. This is handy for translating the example urls in the REST API Reference.

Resources

The following describe the authentication that's happening under the hood and were used heavily in writing this module:

http://developer.netflix.com/docs/Security

Net::OAuth

EXAMPLES ^

The examples/ directory in the distribution has several examples to use as starting points.

There is a vars.inc file in the directory -- most of these example read that for customer key/secret, etc, so fill that file out first to enter your specific values.

Examples include:

login.pl

Takes a netflix account login/password and (for a customer key) obtains an access token, secret, and user_id.

profile.pl

Gets a user's netflix profile and prints the name.

queue.pl

Displays the Disc and Instant queues for a user.

feeds.pl

Grabs all of the user's feeds and stores the .rss files to disk.

history2ical.pl

Converts the rental history (shipped/returned, watched dates) into an ICal calendar (.ics) file.

search.pl

Takes a search string and returns the results from a catalog search.

  $ perl search.pl firefly
  4 results:
  Grave of the Fireflies (1988)
  Firefly Dreams (2001)
  Firefly (2002)
  Serenity (2005)
catalog.pl

Retrieves the entire Netflix catalog and saves it to catalog.xml in the current directory.

catalog-lwp_handlers.pl

Retrieves the entire Netflix catalog and saves it to catalog.xml in the current directory -- uses LWP handlers as an example of modifying the "ua" attribute.

catalog2db.pl

Converts the xmlfile fetched by catalog.pl to a SQLite database. Also contains an example Class::DBI setup for working with the generated database.

Also see the "TEST SUITE" source code for more examples.

METHODS ^

new

This is the constructor. Takes a hashref of "ATTRIBUTES". Inherited from Class::Accessor.

Most important options to pass are the "consumer_key" and "consumer_secret".

REST

This is used to change the resource that is being accessed. Some examples:

  # The user-friendly way:
  $netflix->REST->Users->Feeds;

  # Including numeric parts:
  $netflix->REST->Catalog->Titles->Movies('60021896');

  # Load a pre-formed url (e.g. a title_ref from a previous query)
  $netflix->REST('http://api.netflix.com/users/T1tareQFowlmc8aiTEXBcQ5aed9h_Z8zdmSX1SnrKoOCA-/queues/disc?feed_token=T1u.tZSbY9311F5W0C5eVQXaJ49.KBapZdwjuCiUBzhoJ_.lTGnmES6JfOZbrxsFzf&oauth_consumer_key=v9s778n692e9qvd83wfj9t8c&output=atom');

RequestAccess

This is used to login as a netflix user in order to get an access token.

  my ($access_token, $access_secret, $user_id) = $netflix->RequestAccess( $user, $pass );

Get

Post

Delete

rest2sugar

ATTRIBUTES ^

consumer_key

consumer_secret

access_token

access_secret

user_id

ua

User agent to use under the hood. Defaults to LWP::UserAgent->new(). Can be altered anytime, e.g.

        $netflix->ua->timeout(500);

content_filter

The content returned by the REST calls is POX (plain old XML). Setting this attribute to a code ref will cause the content to be "piped" through it.

  use XML::Simple;
  $netflix->content_filter(  sub { XMLin(@_) }  );  # Parse the XML into a perl data structure

If this is set to a scalar, it will be treated as a filename to store the result to, instead of it going to memory. This is especially useful for retrieving the (large) full catalog -- see "catalog.pl".

  $netflix->content_filter('catalog.xml');
  $netflix->REST->Catalog->Titles->Index;
  $netflix->Get();
  # print `ls -lart catalog.xml`

content

Read-Only. This returns the content from the REST calls. Natively, this is a scalar of POX (plain old XML). If a "content_filter" is set, the "original_content" is filtered through that, and the result is returned as the value of the content attribute (and is cached in the "_filtered_content" attribute.

original_content

Read-Only. This will return a scalar which is simply a dereference of "content_ref".

content_ref

Scalar reference to the original content.

content_error

Read-Only. If an error occurs, this will hold the error message/information.

url

Read-Only.

rest_url

Read-Only.

INTERNAL ^

_url

_params

_levels

_submit

__OAuth_Request

_set_content

Takes scalar reference.

_filtered_content

Used to cache the return value of filtering the content through the content_filter.

WWW::Netflix::API::_UrlAppender

TEST SUITE ^

Most of the test suite in the t/ directory requires a customer key/secret and access token/secret. You can supply these via enviromental variables:

        # *nix
        export WWW_NETFLIX_API__CONSUMER_KEY="qweqweqwew"
        export WWW_NETFLIX_API__CONSUMER_SECRET="asdasd"
        export WWW_NETFLIX_API__LOGIN_USER="you@example.com"
        export WWW_NETFLIX_API__LOGIN_PASS="qpoiuy"
        export WWW_NETFLIX_API__ACCESS_TOKEN="trreqweyueretrewere"
        export WWW_NETFLIX_API__ACCESS_SECRET="mnmbmbdsf"

        REM DOS
        SET WWW_NETFLIX_API__CONSUMER_KEY=qweqweqwew
        SET WWW_NETFLIX_API__CONSUMER_SECRET=asdasd
        SET WWW_NETFLIX_API__LOGIN_USER=you@example.com
        SET WWW_NETFLIX_API__LOGIN_PASS=qpoiuy
        SET WWW_NETFLIX_API__ACCESS_TOKEN=trreqweyueretrewere
        SET WWW_NETFLIX_API__ACCESS_SECRET=mnmbmbdsf

And then, from the extracted distribution directory, either run the whole test suite:

        perl Makefile.PL
        make test

or just execute specific tests:

        prove -v -Ilib t/api.t
        prove -v -Ilib t/access_token.t
