Ruby on rails 将Rails应用程序移动到EC2，现在我的文件上载得到一个Encoding:：UnfinedConversionError（“xC3”从ASCII-8BIT到UTF-8）错误,ruby-on-rails,amazon-web-services,amazon-ec2,paperclip,amazon-elastic-beanstalk,Ruby On Rails,Amazon Web Services,Amazon Ec2,Paperclip,Amazon Elastic Beanstalk,我有一个Rails应用程序，已经运行了一年多，没有任何问题，运行在自定义的Ubuntu/Nginx/Puma设置上由于托管公司的各种问题，我本周末将应用程序转移到EC2上——在他们的Nginx/Puma/Ruby2.2堆栈上使用ElasticBeanstalk 除了上传文件外，一切正常应用程序本身使用回形针gem来处理附件-实际文件在上传到由我的客户机控制的文件服务器之前只是暂时保存在回形针中（最早的版本使用S3存储，但现在它上传，将“工作表”附加到作业上，然后立即上传“工作表”到文件服务器

我有一个Rails应用程序，已经运行了一年多，没有任何问题，运行在自定义的Ubuntu/Nginx/Puma设置上

由于托管公司的各种问题，我本周末将应用程序转移到EC2上——在他们的Nginx/Puma/Ruby2.2堆栈上使用ElasticBeanstalk

除了上传文件外，一切正常

应用程序本身使用回形针gem来处理附件-实际文件在上传到由我的客户机控制的文件服务器之前只是暂时保存在回形针中（最早的版本使用S3存储，但现在它上传，将“工作表”附加到作业上，然后立即上传“工作表”到文件服务器）

正如我所说，在我的旧服务器上，这一切都很正常。但现在，在EC2上，我得到了一个Encoding:：UndefinedConversionError（从ASCII-8BIT到UTF-8的“\xC3”）错误

工作表本身可以是Excel文件或CSV文件。其定义如下：

class Job < ActiveRecord::Base
  ...
  has_attached_file :job_sheet
  validates_attachment_file_name :job_sheet, matches: [/csv\Z/, /xls\Z/, /xlsx\Z/]
  validates_attachment_presence :job_sheet
  ...
end

因此，除了实际逻辑在一个单独的“CreatesJob”类中之外，没有什么不寻常的事情发生——基本上是一种标准的Rails/回形针上传情况

但是，一些上载失败，生产日志中有以下内容：

与此错误相关的其他答案似乎都是关于强制对文件进行编码。但这里的问题似乎是1）有时是二进制文件（xls），有时是文本文件（csv），所以我不能到处乱动它，2）ActionDispatch是个例外；看来在我看到上传之前就发生了

你知道发生了什么事，我能做些什么来修复它吗

更新：我现在可以始终如一地重现问题。如果我上传了一个带有英文文件名的XLSX文件，上传工作正常；如果是带有西班牙语口音的XLSX文件，上传失败，如上所示

有问题的行是@original_filename.encode！（Encoding：：UTF_8）在action_dispatch/http/upload.rb中-然而，文件名应该是有效的unicode，但它显然在传输过程中被损坏了

def create_job params, session: nil
  ...
  job = services['jobs'].create! params.merge(code: code)
  ...
