在S3上回形针处理器超时 [英] Paperclip processor timeout on S3

问题描述

我插入一个数字签名到我的处理器里面的PDF文件，但不断收到 AWS :: S3 ::错误:: Requestimeout 错误。这是什么超时？有什么办法，我可以保持连接打开，直到该文件被上传？

  

您socket连接到服务器无法读取或写入   在超时期限内。空闲连接将被关闭。

下面是我的code：

模式：

  ...

has_attached_file：receipt_file，
                    ：存储=＆GT; ：S3，
                    ：s3_credentials =＆GT; ＃{Rails.root} /config/s3.yml
                    ：PATH =＆GT; /：款式/：ID /：文件名，
                    ：s3_protocol =＆GT; https开头，
                    ：风格=＆GT; {假：}​​，
                    处理器：[：SignPdf]
 #process_in_background：receipt_file

解决方案

我身边有这个工作，使用后保存。见我的回答与本主题 href="http://stackoverflow.com/a/12354693/1461972">

I'm inserting a digital signature into a pdf file inside my processor, but keep getting an AWS::S3::ERRORS::Requestimeout error. What is this timeout? Is there any way i could keep the connection open until the file gets uploaded ?

Your socket connection to the server was not read from or written to within the timeout period. Idle connections will be closed.

Here is my code :

model:

...

has_attached_file :receipt_file,
                    :storage => :s3,
                    :s3_credentials => "#{Rails.root}/config/s3.yml",
                    :path => "/:style/:id/:filename",
                    :s3_protocol => "https",
                    :styles => {dummy:""},
                    processors: [:SignPdf]
 #process_in_background :receipt_file

...

Processor

module Paperclip


    class SignPdf < Processor
      attr_accessor :receipt_id,:style
     S3_CONFIG = YAML.load_file("#{::Rails.root}/config/s3.yml")[Rails.env]
     ORIGAMIDIR = "/ruby/1.9.1/gems/origami-1.2.4/lib"


      def initialize(file, options = {}, attachment = nil)
        @file           = file
        @current_format = File.extname(@file.path)
        @basename       = File.basename(@file.path, @current_format)
        @attachment = attachment
      end

        def make

         signPdf(@file) 
         @file
      end

    end
end

begin
  require 'origami'
rescue LoadError
  $: << ORIGAMIDIR
  require 'origami'
end
include Origami
def signPdf(file)

        certFile = "#{::Rails.root}/lib/assets/Cert.pem"
        rsakeyFile = "#{::Rails.root}/lib/assets/pk.pem"
        passphrase = "o2Receipts"

        key4pem=File.read rsakeyFile
        key = OpenSSL::PKey::RSA.new key4pem, passphrase
        cert = OpenSSL::X509::Certificate.new(File.read certFile)

        pdf = PDF.read(file)
        page = pdf.get_page(1)

        # Add signature annotation (so it becomes visibles in pdf document)

        sigannot = Annotation::Widget::Signature.new
        sigannot.Rect = Rectangle[:llx => 89.0, :lly => 386.0, :urx => 190.0, :ury => 353.0]

        page.add_annot(sigannot)

        # Sign the PDF with the specified keys
        pdf.sign(cert, key, 
          :method => 'adbe.pkcs7.sha1',
          :annotation => sigannot, 
          :location => "Portugal", 
          :contact => "[e-mail]", 
          :reason => "Proof of Concept"
        )

        # Save the resulting file
        pdf.save(file.path)
        file
end      

解决方案

I have worked around this, by using the after save. See my answer related to this subject here
