[fw-general] Pre-Proposal Feedback Requested Zend_View_Helper_S3Link

2009-08-19 Thread J DeBord 
A view helper that allows easy creation of Amazon Web Services S3 Query
String Authentication urls.

In short, query string authentication allows creation of URLS that can
access private S3 objects which would otherwise require authentication. The
created URLS have an expiration time. One use for this is to only allow
links to your images stored on S3 to be available to viewers of your
website. (technically speaking to anyone having the created *unexpired *
link)

Usage in a view script: img src=?= $this-S3link('mybucket/myobject.jpg',
30); ? alt= /

The above would generate something similar to:

img src=
http://s3.amazonaws.com/mybucket/myobject.jpg?AWSAccessKeyId=44CF9590006BF252F707Expire
s=1250687683Signature=vjbyAxhzyZaNvGa%2ByT45YEenS4%3D alt= /

This would provide a working link to the otherwise private myobject.jpg
object inside of the mybucket bucket. The link would be valid for 30
seconds. After 30 seconds the object would no longer be accessible using
this url.

I have been using this view helper for some time now. I am very interested
in creating a proposal, refactoring my code to meet ZF standards, and
eventually having this view helper included in the Zend Framework.

Thanks for your time. I appreciate it.

Jason

This looks like a great helper! I'd like to see a sane default of
60-120s on the expiration (to give people a chance to read the page and
follow the links), but otherwise, seems like a natural fit. Please *do*
create the proposal! :)

Matthew and all,

I've created the proposal here:
http://framework.zend.com/wiki/display/ZFPROP/Zend_View_Helper_S3Link+-+Jason+DeBord

Of course I'd love to receive some feedback / questions / advice etc. So if
you have a minute, take a look.

One immediate concern I have is how to supply the AWS public and private
keys to the view helper. Entering them as arguments is not a good idea. I
currently store my keys in a Zend_Config object which is used as a resource
of Zend_Application. Then I access them in the view helper's constructor.
This seems to create some dependencies that I'd like to avoid. Is there a
way to bootstrap a view helper. Maybe set up some static variables for
each of the public keys?

Thanks again for your tilme.

 interested in

 eventually
  having this view helper included in the Zend Framework.
