我使用Carrierwave添加了使用base64映像的解决方案,以便从java类上传图像.这就是我的FileUploader类的样子 - 我相信问题出在哪里:

# encoding: utf-8

class FileUploader < CarrierWave::Uploader::Base

  # Include RMagick or MiniMagick support:
    include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  storage :file
  # storage :fog

  #START FROM BASE64 POST LINKED ABOVE
  class FilelessIO < StringIO
    attr_accessor :original_filename
    attr_accessor :content_type
  end

  before :cache, :convert_base64

  def convert_base64(file)
    if file.respond_to?(:original_filename) &&
        file.original_filename.match(/^base64:/)
      fname = file.original_filename.gsub(/^base64:/, '')
      ctype = file.content_type
      decoded = Base64.decode64(file.read)
      file.file.tempfile.close!
      decoded = FilelessIO.new(decoded)
      decoded.original_filename …

有没有办法将字符串转换为ActionDispatch::Http::UploadedFile

我需要它能够在 API 请求中传递文件路径来处理将 Excel 插入数据库的操作，因为我想使用 REST API 而不是浏览器来上传文件。

谢谢
