我正在使用以下文件上传：Rails 3.2,Paperclip(3.0.4),aws-sdk(1.5.2)& jQuery的文件上传
问题是办公室文件(pptx)正在下载为zip文件而不是pptx文件.这是我在日志中看到的：

解决方法
事实证明,正如Marc B首先暗示的那样 – x结尾的所有Office文档确实是压缩的XML文件.任何使用正常模式的东西都会认为它是一个压缩文件.
要解决这个问题,你必须要register the Office mimetypes with your server.所以,对于你的.pptx文件,你放了
Mime::Type.register "application/vnd.openxmlformats-officedocument.presentationml.presentation",:pptx
在你的config / initializers / mime_types.rb文件中.
或者,您可以使用Rack :: Mime :: MIME_TYPES.merge！()方法,如果您必须支持所有Office 2007文件,则在this Stackoverflow answer中可以看到该方法.
