我正在使用Rails 5。我想要从一个Word文档(.doc)中获取文本,因此我使用了这段代码:
text = nil
MSWordDoc::Extractor.load(file_location) do |ctl00_MainContent_List1_grdData|
text = contents.whole_contents
end
但我得到了下面的错误。 我在Gemfile中有这个gem。
gem 'msworddoc-extractor'
我需要做什么才能从Word文档中提取内容?如果我能够将同样的代码应用于.docx
文件,就太好了。

file
命令,例如file your.doc
,它会输出文件类型:Microsoft Word 2007+
或Composite Document File V2 Document, Little Endian, Os: Windows, Version 5.1, Code page: 1252
。这有助于确定文件的类型。这使用相同类型的“魔术测试”来确定文件头是什么类型的文件。 - anothermh
