This is a fork of the “Amazon Hacks” gem since the original appears to be abandoned.¶ ↑
At this time, I have just updated the logic surrounding deriving an image URL from a product URL. I’ve kept the original README contents intact below.
Feel free to fork and send a pull request if you wish to make other updates.
To reference this fork in your project, list it in your Gemfile as such :
gem 'amazon-hacks', :git => 'git@github.com:aantix/amazon_hacks.git'
ORIGINAL README¶ ↑
AmazonHacks
by Jacob Harris harrisj@schizopolis.net Blog: http://www.nimblecode.com/ NYC.rb: http://www.nycruby.org/
DESCRIPTION:¶ ↑
Mainly the product of messing around, this gem comprises Ruby code for a few useful “Amazon Hacks” – common techniques for manipulating Amazon product URLs and Images. This is mainly useful if you find yourself creating a site where you might link to Amazon product pages and display images for them. Examples of this might include:
-
Social consumption sites like All Consuming
-
Blogs or tumbleblogs with book/music/etc. reviews
-
Normalizing Amazon links or create associate IDs
This GEM is NOT related to using the Amazon Web Services and there is already an excellent gem for that if you need more heavy-duty use of the Amazon website (this gem does not even communicate with Amazon at all). Also, note this gem is meant in the spirit of fun hackery. You can use it to create interesting images from Amazon on demand, but if you are going to use it on a serious website, please consider caching and attributing that image to Amazon (I also have no idea what the official legal policy for using Amazon’s book images is).
And of course, do not even consider using this for fraud. It is possible to generate “20% off” or “Look Inside!” badges on Amazon images, but this gem does not support that since I can not think of any reason why outside sites would use that.
FEATURES/PROBLEMS:¶ ↑
There are two main classes within the Amazon::Hacks namespace with the following functionality:
Link (product URL)¶ ↑
-
Extract country of site
-
Extract ASIN (Amazon identifier)
-
Normalize (reduce to most basic URL for matching)
-
Associate URL (create a normalized URL with your Amazon Associate ID)
Image¶ ↑
-
Derive a corresponding image URL from a product URL
-
Sizes (small, medium, large)
-
Shadow
-
Border
-
Crop
-
Scale
-
Tilt
-
Blur
-
Sharpen
-
Highlight
-
Text overlay
This is still a work in development, and while I have tested against some generic Amazon rules, it is possible that certain countries might deviate from Amazon’s practices (for instance, China seems to not use the image generation code and instead just links to static URLs). Let me know if you find any issues for a given product link/image. Thank you.
