[Koha] Amazon Reviews not displaying

[m.mason at ytu.edu.au]

Amazon now requires the SECRET /Private key for all except covers. 
But there does not seem to be a Koha System preference for this until 
version 3.2.

 From Koha 3.2 manual:





Why do I need a AWSPrivateKey for Amazon Content?

This FAQ applies to: 3.2
Why do I need the AWSPrivateKey as well as the AWSAccessKeyID to use 
Amazon Content?

After 2009-08-15, Amazon Web Services will expect that all requests 
to the Product Advertising API, which is what Koha uses for 
retrieving reviews and other enhanced content from Amazon, include 
signatures.  This patch and subsequenct patches implement this functionality.

What this means in practice (assuming the user has elected to use any 
enhanced content from Amazon) is that
    * The user must get a Amazon Secret Access Key.  This can be done 
by logging in to the user's AWS account at (e.g.) 
<http://aws.amazon.com/>http://aws.amazon.com/, going to the 'Access 
Identifiers' page, and from there retrieving and/or creating a new 
Secret Access Key.
    * The contents of the Secret Access Key should then be entered 
into the new AWSPrivateKey system preference.

Once that is done, grabbing reviews and table of contents from Amazon 
should work as normal.  If the user doesn't do this before 
2009-08-15, reviews and TOCs will no longer be supplied from Amazon, 
although there should be no crashes - the content will simply not show up.

Note that the requirement to sign requests does *NOT* appear to apply 
to simply displaying book covers from Amazon.
