Description

The Google cloud storage provider can PUT, but not GET a blob containing "/" in its name. When attempting to retrieve "foo/bar", null is always returned.

The reason for this behavior is twofold. First, Google expects "/" in the path parameters to be percent-encoded. Secondly, jclouds-core does not have a way to express that a specific path parameter should be encoded prior to being added to the path.

Currently, the rest processor does the following for the endpoint: assemble all of the tokens together and call

urlEncode()

on the result. When it does so, it also skips encoding any "/" characters. If an encoded token is passed to the processor, it ends up being encoded twice, as the "%" character is encoded as %25.

jclouds-core should add

@Encoded

parameter annotation, which would encode each parameter individually (including any "/" characters) before assembling the URL. In this case, the consumers of the API must make sure that they do not need the entire path to be encoded.

I plan to submit a PR to add the annotation and to use it in the google-cloud-storage provider. When the annotation is not used, endpoints will be processed as is.
