Ruby on rails Carrierwave、Fog、Amazon S3、Rails 4

我试图让Carrierwave使用我的Amazon S3水桶，但我的运气有点不好。在我的

config/initializers

文件夹中，有一个名为

carrierwave.rb的文件。此文件包含以下内容：

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
作为存储环境配置变量的机制。在
application.yml
内部，我定义了
ENV['AWS\u ACCESS\u KEY\u ID']
，
ENV['AWS\u SECRET\u ACCESS\u KEY']
，以及
ENV['AWS\u S3\u BUCKET']

这三个变量似乎是正确填充的。使用FTP程序，我可以连接到AmazonS3实例，使用我在
application.yml
文件中定义的访问密钥和秘密访问密钥。我已经三次检查了我的public和secret密钥是否正确

尝试在Rails应用程序中执行上载时，我收到一个错误，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>

提前谢谢

编辑：添加了几个内容：

我刚刚尝试创建一组新的密钥，并再次将密钥复制并粘贴到我的
carrierwave.rb
文件中。我仍然收到同样的错误。我的文件内容如下：

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存储桶的响应。注意-下面列出的公共访问密钥是正确的。不确定将秘密访问密钥传入的位置？：

似乎Fog正在使用“excon”连接S3铲斗。我通过消除雾和excon 0.27.2解决了问题。我切换到
carrierwave aws
gem（使用相同的凭证，一切都正常工作）
 有没有可能有多余的空间？或者可能是密钥的URL编码问题？像这样奇怪的事情可能在起作用。嘿，谢谢你的回复。我刚才用访问密钥和秘密访问密钥（直接从amazon复制和粘贴）再试了一次。在这方面仍然没有运气：-（…另外，我应该注意，每次更改配置时，我都会重新启动本地主机服务器，以确保我的启动是干净的。你能看到CarrierWave发送到S3的内容的日志吗？我感觉在从CarrierWave.rb到堆栈的翻译过程中丢失了一些内容。+1，我从Amazo的响应中添加了一个转储n、 我还可以去哪里查看Carrierwave发送的内容？公共访问密钥似乎正确..很好地抓住了问题的核心。
