Play 2.0 RESTful request post-processing

阅读更多关于 Play 2.0 RESTful request post-processing

问题 In regard to this question I am curious how one can do post-request REST processing a la (crude): def postProcessor[T](content: T) = { request match { case Accepts.Json() => asJson(content) case Accepts.Xml() => asXml(content) case _ => content } } overriding onRouteRequest in Global config does not appear to provide access to body of the response, so it would seem that Action composition is the way to go to intercept the response and do post-processing task(s). Question: is this a good idea,

阅读更多关于 Rails 4 and paperclip - Stop the :original style file upload to copy it from an S3 remote directory

问题 I have a post-hook function that receives some data for itself, reference to another function and arguments for that arbitrary function in ... .

How can I

How to read plist information (bundle id) from a shell script

阅读更多关于 How to read plist information (bundle id) from a shell script

Defaults also works with binary plists without any extra
