DESCRIPTION

This module obtains recommended items in Amazon by using WWW::Mechanize.

To spcify category, you need to specify URL itself. To specify some constants or short-hand key is considered but currently rejected because category names are dependent on domains and it is difficult to enumerate all possible sub categories.

METHODS

new(%options)

Constructor. The following options are available.

email => $email

Specify an email as a login ID.

password => $password

Specify a password.

domain => $domain

Domain of Amazon e.g. 'com'. Defaults to 'co.jp'. 'com', 'co.uk' and 'co.jp' are checked. It might work for other domains.

get($url, $max_pages = 1)

Returns array reference of recommended items. Each element is a hash reference having the following keys:

id

ASIN ID.

url

URL for the item like http://www.amazon.co.jp/dp/4873110963. Just an ASIN is used and other components are stripped.

image_url

URL of cover image.

title

Title.

author

Author.

date

DateTime object of publish date.

price

price in just a string. Currency symbol is included.

listprice

list price in just a string. Currency symbol is included.

otherprice

price by other sellers in just a string. Currency symbol is included.

$url can be sub category page like http://www.amazon.co.jp/gp/yourstore/recs/ref=pd_ys_nav_b_515826?ie=UTF8&nodeID=515826&parentID=492352&parentStoreNode=492352.

$max_page is the limitation of retrieving pages. Defaults to 1. To specify undef explicitly means no limitation, that is all recommended items are retrieved.

get_list($type, $max_pages = 1)

Returns array reference of items in the specified type. $type can be 'notinterested', 'owned', 'purchased' or 'rated'.

Each element is a hash reference having the following keys:

id

ASIN ID.

url

URL for the item like http://www.amazon.co.jp/dp/4873110963. Just an ASIN is used and other components are stripped.

image_url

URL of cover image.

title

Title.

author

Author. It might be empty.

starRating

Rated value for this item from 1 to 5. 0 means not rated. This key is avaiable for the case that $type is 'owned', 'purchased' or 'rated'.

isNotInterested

1 means this item is not interested. 0 means not. This key is avaiable for the case that $type is 'notinterested'.

isExcluded

1 means this item is not considered for recommendation. 0 means considered. This key is avaiable for the case that $type is 'owned', 'purchased' or 'rated'.

$max_page is the limitation of retrieving pages. Defaults to 1. To specify undef explicitly means no limitation, that is all recommended items are retrieved.

get_status($asin)

Returns a hash reference having the following keys. If the corresponding item is not found, undef is returned. Unfortunately, it seems to be that only 'co.jp' provides the interface /gp/rate-it/ used by this method. Other domains moved to /gp/betterizer/ intefrace. To set some state by set_status() then calling get_last_status() or get_list() might be used as workaround.

starRating

Rated value for this item from 1 to 5. 0 means not rated.

isOwned

1 means this item is owned. 0 means not.

get_last_status($type)

Returns a hash reference having the following keys for the last item of $type.

starRating

Rated value for this item from 1 to 5. 0 means not rated. This key is avaiable for the case that $type is 'owned' or 'rated'.

isNotInterested

1 means this item is not interested. 0 means not. This key is avaiable for the case that $type is 'notinterested'.

isExcluded

1 means this item is not considered for recommendation. 0 means considered. This key is avaiable for the case that $type is 'owned' or 'rated'.

$type is case-insensitive.

set_status($asin, \%args)

%arg is a hash having some of the following keys.

starRating

Rated value for this item from 1 to 5. 0 means not rated.

isOwned

1 means this item is owned. 0 means not.

isNotInterested

1 means this item is not interested. 0 means not.

isExcluded

TEST

To test this module completely, you need to specify environment variables AMAZON_EMAIL and AMAZON_PASSWORD.

Because results of some tests are dependent on purchase history, they are marked as TODO.

CAUTIONS: Some tests, 03-status.t, 05-domain.t and 06-domain.t will change your recommendation configurations.
