Я пытаюсь загрузить PDF файл из электронной почты и записать содержимое в файл. По какой-то причине я получаю эту ошибку:
An Encoding::UndefinedConversionError occurred in attachments#inbound: "\xE2" from ASCII-8BIT to UTF-8 app/controllers/api/attachments_controller.rb:70:in `write'
Здесь мой код:
def inbound
if Rails.env.production? or Rails.env.staging?
email = Postmark::Mitt.new(request.body.read)
else
email = Postmark::Mitt.new(File.binread "#{Rails.root}/app/temp_pdfs/email.json")
end
if email.attachments.count == 0
# notify aidin that we got an inbound email with no attachments
respond_to do |format|
format.json { head :no_content }
end
return
end
attachment = email.attachments.first
filename = "attachment" + (Time.now.strftime("%Y%m%d%H%M%S")+(rand * 1000000).round.to_s) + ".pdf"
base_path = "#{Rails.root}/temp_attachments/"
unless File.directory?(base_path)
Dir::mkdir(base_path)
end
file = File.new base_path + filename, 'w+'
file.write Base64.decode64(attachment.source['Content'].encode("UTF-16BE", :invalid=>:replace, :replace=>"?").encode("UTF-8"))
file.close
write_options = write_options()
write_options[:metadata] = {:filename => attachment.file_name, :content_type => attachment.content_type, :size => attachment.size }
obj = s3_object()
file = File.open file.path
obj.write(file.read, write_options)
file.close
FaxAttach.trigger obj.key.split('/').last
render :nothing => true, :status => 202 and return
end
Я читал, и это выглядело так, как это можно было решить:
file.write Base64.decode64(attachment.source['Content'].encode("UTF-16BE", :invalid=>:replace, :replace=>"?").encode("UTF-8"))
но он не работает.
