You can clone with
HTTPS or Subversion.
Rails ~> 3.1.3
ActiveResource::Base.format = :xml
ActiveResource::Base.site set to an https uri.
Some non-ascii chars in the payload
class Post < ActiveResource::Base
self.site = 'https://secureapi.example.com'
self.format = :xml
post = Post.find(1)
post.title = "Café!"
Ruby 1.9.2p.290 has an OpenSSL::Buffering bug that affects active resource with ssl sites.
In Rails, JSON appears to be unaffected as it already forces binary encoding in it's encode method.
I believe a well placed .force_encoding(::Encoding::BINARY) in the to_xml chain would fix the issue. I'm not too familiar with the XMLMini code and had trouble finding a place to focus my efforts. I am more than willing to tackle the issue with a little direction, but wanted to get the issue into the open first.
For the time being, here's a workaround I'm using in a production app hosted on Heroku cedar.
Is this still a problem?
ActiveResource has been extracted to its own repo, so I'll ask you to send a new issue / pull request to there in case you still find this is an issue. Thanks.
