Ruby/AWS is a Ruby language library that allows programmatic access to the popular Amazon Web sites via the AWS v4 API. It is the successor to the now obsolete Ruby/Amazon. In addition to the original amazon.com[http://www.amazon.com/exec/obidos/redirect-home/calibanorg-20] site, the local sites amazon.co.uk[http://www.amazon.co.uk/exec/obidos/redirect-home/caliban-21], amazon.de[http://www.amazon.de/exec/obidos/redirect-home/calibanorg0a-21], amazon.fr[http://www.amazon.fr/exec/obidos/redirect-home/caliban08-21], amazon.ca[http://www.amazon.ca/exec/obidos/redirect-home/caliban-20] and amazon.co.jp[http://www.amazon.co.jp/exec/obidos/redirect-home/calibanorg-20] are also supported. Although the library is still in development, the AWS v4 API is now more or less fully supported, with only tiny gaps in the functionality of some operations. The following operations are supported: BrowseNodeLookup CustomerContentLookup CustomerContentSearch Help ItemLookup ItemSearch ListLookup ListSearch SellerListingLookup SellerListingSearch SellerLookup SimilarityLookup TagLookup TransactionLookup Remote shopping-carts are also supported. This adds the following operations: CartCreate CartAdd CartModify CartClear CartGet In addition, multiple operations and batch requests are also supported. Ruby/AWS also offers advanced features not directly available in the AWS API, such as the ability to retrieve *all* results pages for a particular search, rather than having to manually deal with AWS responses of 10 results per page. You can also retrieve product images and optionally overlay them with percentage discount icons. Another advanced feature is the ability to cache responses returned by AWS. If the cache is used (as it is by default), the results of each unique query will be cached and used for 24 hours. The cache can be manually flushed of all or just the expired entries. One other useful advanced feature is the ability to determine the appropriate Amazon locale for a given client, based on its IP address or host name. This allows you to perform AWS operations using the correct geographical Amazon site for any given client. German and Austrian clients can be made to interact with amazon.de, British and Irish clients with amazon.co.uk, etc.
Please see the +INSTALL+ file supplied with the software for details of how
to install Ruby/AWS. You can choose between an installation script and a
RubyGems[http://www.rubygems.org/] installation.
Note, however, if choosing the gem installation, that whilst Ruby/AWS's
RubyForge UNIX name is now ruby-aaws. The ruby-aws name was taken by
{another project}[http://rubyforge.org/projects/ruby-aws/] and this clash
prevented remote installation of the Ruby/AWS gem.
Before you can use this library, you need to obtain an Amazon Web Services
{access key
ID}[https://aws-portal.amazon.com/gp/aws/developer/registration/index.html].
You should also apply for an {Associates
account}[http://docs.amazonwebservices.com/AWSECommerceService/2008-04-07/GSG/BecominganAssociate.html],
although this isn't strictly necessary. If you do not explicitly provide an
Associates tag in your calls through Ruby/AWS, the tag of the Ruby/AWS
author will be used by default.
Ultimately, the way to get the most from this library is to read the AWS
documentation to get a feel for what is possible, and then experiment with
this library to see how the AWS calls are mapped into the Ruby world. You
should also review this library's
RDoc[http://www.ruby-doc.org/core/classes/RDoc.html]
documentation[http://www.caliban.org/ruby/ruby-aws/] as well as the
plain-text +README+ file that came with the archive.
Additionally, there's a
{mailing-list}[http://www.caliban.org/mailman/listinfo/ruby-aws] available,
where you can discuss all Ruby/AWS-related subjects and issues.
Please see the Amazon Web Services
documentation[http://developer.amazonwebservices.com/connect/kbcategory.jspa?categoryID=5]
for definitive information on the capabilities and inner workings of the AWS
API.
