我已经注册了一个MIME类型，以允许回形针将.docx文件的content_type读取为application/vnd.openxmlformats-officedocument.wordprocessingml.document。
但是，在测试中，content_type仍被读取为application/zip。
知道为什么吗？更令人沮丧的是，.pptx和.xlsxMIME 类型已经注册，这些测试通过了(urgh(。

感谢您的帮助。
编辑：
根据 bkunzi01 提供的链接，我尝试了以下代码。它没有效果，.docx文件在.pptx和.xlsx通过时仍然无法通过验证。
config/application.rb
Paperclip.options[:content_type_mappings] = {
docx: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
pptx: 'application/vnd.openxmlformats-officedocument.presentationml.presentation',
xlsx: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
}
似乎新版本的回形针导致了此问题。降级到版本 4.3.1 应该可以解决您的问题
