1 Net-Amazon-S3-Policy version 0.1.3
3 Net::Amazon::S3::Policy gives you an object-oriented interface to man‐
4 age policies for Amazon S3 HTTP POST uploads.
6 Amazon S3 relies upon either a REST interface (see Net::Amazon::S3) or
7 a SOAP one; as an added service, it is possible to give access to the
8 upload of resources using HTTP POSTs that do not involve using any of
9 these two interfaces, but a single HTML FORM. The rules you have to
10 follow are explained in the Amazon S3 Developer Guide.
12 More or less, it boils down to the following:
14 · if the target bucket is not writeable by the anonymous group,
15 you’ll need to set an access policy;
17 · almost every field in the HTML FORM that will be used to build up
18 the HTTP POST message by the browser needs to be included into a
19 policy, and the policy has to be sent along within the HTTP POST
21 · together with the policy, also the bucket owner’s AWS ID (the pub‐
22 lic one) has to be sent, together with a digital signature of the
23 policy that has to be created using the bucket owner’s AWS secret
26 This module lets you manage the build-up of a policy document, provid‐
27 ing you with tools to get the Base64 encoding of the resulting JSON
28 policy document, and to calculate the Base64 encoding of the signature.
29 See "Example" for a complete example of how to do this.
31 In addition to policy synthesis, the module is also capable of parsing
32 some policy (base64-encoded or not, but in JSON format). This shouldn’t
33 be a need in general... possibly for debug reasons.
