write_buffer 而不是打开的 RubyZip docx 问题

Question

我正在调整 RubyZip 递归压缩示例 (found here) to work with write_buffer instead of open and am coming across a host of issues. I'm doing this because the zip archive I'm producing has word documents in it and I'm getting errors on opening those word documents. Therefore, I'm trying the work-around that RubyZip suggests, which is using write_buffer instead of open (example found here)。

问题是，我遇到错误是因为我使用的是绝对路径，但我不确定如何解决这个问题。我收到错误消息“#//'，名称不能以 /> 开头”

其次，我不确定如何缓解 word 文档的问题。当我使用我的原始代码时，该代码有效并创建了一个实际的 zip 文件，该 zip 文件中的任何 word 文档在打开时都会出现以下错误："Word found unreadable content in Do you want to recover the contents of this document? If you trust the source of this document, click Yes." The unreadable content error 是我尝试尝试的原因使用 write_buffer.

如有任何帮助，我们将不胜感激。

这是我目前使用的代码：

require 'zip'
require 'zip/zipfilesystem'

module AdvisoryBoard
  class ZipService
    def initialize(input_dir, output_file)
      @input_dir = input_dir
      @output_file = output_file
    end

    # Zip the input directory.
    def write
      entries = Dir.entries(@input_dir) - %w[. ..]
      path = ""

      buffer = Zip::ZipOutputStream.write_buffer do |zipfile|
        entries.each do |e|
          zipfile_path = path == '' ? e : File.join(path, e)
          disk_file_path = File.join(@input_dir, zipfile_path)

          @file = nil
          @data = nil

          if !File.directory?(disk_file_path)
            @file = File.open(disk_file_path, "r+b")
            @data = @file.read

            unless [@output_file, @input_dir].include?(e)
              zipfile.put_next_entry(e)
              zipfile.write @data
            end

            @file.close
          end
        end

        zipfile.put_next_entry(@output_file)

        zipfile.put_next_entry(@input_dir)
      end

      File.open(@output_file, "wb") { |f| f.write(buffer.string) }
    end
  end
end

我能够在没有任何警告或损坏的情况下打开 word 文档！这是我最后做的：

require 'nokogiri'
require 'zip'
require 'zip/zipfilesystem'

  class ZipService
    # Initialize with the directory to zip and the location of the output archive.
    def initialize(input_dir, output_file)
      @input_dir = input_dir
      @output_file = output_file
    end

    # Zip the input directory.
    def write
      entries = Dir.entries(@input_dir) - %w[. ..]

      ::Zip::File.open(@output_file, ::Zip::File::CREATE) do |zipfile|
        write_entries entries, '', zipfile
      end
    end

    private

    # A helper method to make the recursion work.
    def write_entries(entries, path, zipfile)
      entries.each do |e|
        zipfile_path = path == '' ? e : File.join(path, e)
        disk_file_path = File.join(@input_dir, zipfile_path)

        if File.directory? disk_file_path
          recursively_deflate_directory(disk_file_path, zipfile, zipfile_path)
        else
          put_into_archive(disk_file_path, zipfile, zipfile_path, e)
        end
      end
    end

    def recursively_deflate_directory(disk_file_path, zipfile, zipfile_path)
      zipfile.mkdir zipfile_path
      subdir = Dir.entries(disk_file_path) - %w[. ..]
      write_entries subdir, zipfile_path, zipfile
    end

    def put_into_archive(disk_file_path, zipfile, zipfile_path, entry)
      if File.extname(zipfile_path) == ".docx"
        Zip::File.open(disk_file_path) do |zip|
          doc = zip.read("word/document.xml")
          xml = Nokogiri::XML.parse(doc)
          zip.get_output_stream("word/document.xml") {|f| f.write(xml.to_s)}
        end
        zipfile.add(zipfile_path, disk_file_path)
      else
        zipfile.add(zipfile_path, disk_file_path)
      end
    end
  end
