aastring = "public/images/"+Time.now.strftime("%y-%m-%d")+(file.original_filename) File.open(aastring,"wb+") do |f| f.write(file.read) render(:text=>"afterupload :"+aastring+"上传成功！！！") end

加入这么一行就好了
CarrierWave::SanitizedFile.sanitize_regexp = /[^[:word:].-+]/

Filenames and unicode chars

Another security issue you should care for is the file names (see Ruby On Rails Security Guide). By default, CarrierWave provides only English letters, arabic numerals and '-+_.' symbols as white-listed characters in the file name. If you want to support local scripts (Cyrillic letters, letters with diacritics and so on), you have to override sanitize_regexp method. It should return regular expression which would match all non-allowed symbols.

With Ruby 1.9 and higher you can simply write (as it has Oniguruma built-in):

CarrierWave::SanitizedFile.sanitize_regexp = /[^[:word:].-+]/

With Ruby 1.8 you have to manually specify all character ranges. For example, for files which may contain Russian letters:

CarrierWave::SanitizedFile.sanitize_regexp = /[^a-zA-Zа-яА-ЯёЁ0-9.-+_]/u

Also make sure that allowing non-latin characters won't cause a compatibility issue with a third-party plugins or client-side software.
