ruby-on-rails – Carrierwave,Fog,Amazon S3,Rails 4

CarrierWave.configure do |config|
  config.fog_credentials = {
      :provider               => 'AWS',:aws_access_key_id      => ENV['AWS_ACCESS_KEY_ID'],:aws_secret_access_key  => ENV['AWS_SECRET_ACCESS_KEY']
  }
  config.cache_dir = "#{Rails.root}/tmp/uploads"
  config.fog_directory  = ENV['AWS_S3_BUCKET']
  config.fog_public     = true
  config.fog_attributes = {'Cache-Control' => 'max-age=315576000'}
end

我使用gem figaro作为容纳我的环境配置变量的机制.在application.yml中,我定义了ENV [‘AWS_ACCESS_KEY_ID’],ENV [‘AWS_SECRET_ACCESS_KEY’]和ENV [‘AWS_S3_BUCKET’].

这三个变量似乎正在填充.使用FTP程序,我可以使用我在application.yml文件中定义的访问密钥和秘密访问密钥连接到我的amazon s3实例.我已经三次检查我的公钥和密钥是否正确.

尝试在我的Rails应用程序中执行上载时,收到错误消息,指出：

Expected(200) <=> Actual(403 Forbidden) response => #<Excon::Response:0x007fb29a862ac8 
@data={:body=>"<?xml version="1.0" encoding="UTF-8"?>n<Error><
Code>SignatureDoesNotMatch</Code>
<Message>The request signature we calculated does not match the signature you provided. 
Check your key and signing method.</Message>

为了解决这个问题,我还试图：

>创建一个新的Amazon S3存储桶
>手动将access_key_id / secret_access_key / fog_directory放入配置文件中.

这两个选项似乎都没有起作用.当我创建一个新的S3存储桶并在config.fog_directory中指定它时,我收到了同样的错误.

当我在carrierwave.rb文件中手动键入密钥和存储桶名称时,我仍然收到相同的错误.

我尝试在网上搜索一下答案,但大多数答案似乎是用户错误地键入了错误的访问密钥或密钥.我不相信这是这种情况,因为我已经将密钥直接复制并粘贴到亚马逊上S3管理控制台的carrierwave.rb文件中.

如果有人有任何想要我尝试的见解或事情,请随时发表评论.如果您需要更多信息,请告诉我,我会在此发布.我的应用程序是一个Rails 4应用程序,具有以下宝石：

gem 'carrierwave'
gem 'fog',github: 'fog/fog'
gem 'mini_magick'
gem 'figaro'

提前致谢！

编辑：几个补充：

我刚刚尝试创建一组新密钥,然后再次将密钥粘贴到我的carrierwave.rb文件中.我仍然收到同样的错误.我的文件现在如下所示：

CarrierWave.configure do |config|
  config.fog_credentials = {
      :provider               => 'AWS',:aws_access_key_id      => "***********",:aws_secret_access_key  => "***********"
  }

  config.cache_dir = "#{Rails.root}/tmp/uploads"
  config.fog_directory  = 'soawsthree'
  config.fog_public     = true
  config.fog_attributes = {'Cache-Control' => 'max-age=315576000'}
end

来自S3 Bucket的回复.注意 – 下面列出的公共访问密钥是正确的.不确定秘密访问密钥的传入位置？：
