无法在Rails应用中将图片托管配置为AWS s3

标签: ruby-on-rails amazon-s3 carrierwave amazon-iam

最近,我开始使用Michael Hartl的Ruby on Rails教程学习Rails。我已经完成了本教程,但是未能为用户的微博配置将图像上传到s3。

我已经配置了carrier_wave.rb文件,在aws中创建了一个IAM用户和一个s3存储桶,并将策略附加到IAM用户以访问我的存储桶。似乎没什么用,我总是得到

"Excon::Error::Forbidden (Expected(200) <=> Actual(403 Forbidden)
2019-04-19T04:52:31.446436+00:00 app[web.1]: excon.error.response" 

尝试在生产环境中上传图像时出错

Heroku日志-(我已将日志中的heroku应用和s3存储桶名称替换为我的heroku应用s3存储桶名称

carrier-wave.rb

if Rails.env.production?
  CarrierWave.configure do |config|
    config.fog_credentials = {
      # Configuration for Amazon S3
      :provider              => 'AWS',
      :aws_access_key_id     => ENV['S3_ACCESS_KEY'],
      :aws_secret_access_key => ENV['S3_SECRET_KEY'],

    }
    config.fog_directory     =  ENV['S3_BUCKET']
  end
end

我已经使用...设置了访问密钥,秘密密钥和存储桶。

$ heroku config:set S3_ACCESS_KEY= <access key> 
$ heroku config:set S3_SECRET_KEY= <secret key> 
$ heroku config:set S3_BUCKET= <bucket name>

我已经尝试过更改s3存储桶区域,我的存储桶位于默认区域,并且已经在heroku中验证了我的配置变量,正确设置了S3_ACCESS_KEY,S3_SECRET_KEY和S3_BUCKET,并且S3_REGION = us-east-2。 / p>

这是我第一次与aws合作,如果有人可以帮助我解决这个问题,那就太好了。

1 个答案:

答案 0 :(得分:0)

我仍然没有解决该问题的明确方法。我不得不面对两个问题...

  1. “ us-east-1”区域错误;期待'us-east-2',我通过添加以下行

    修复了该错误
    :region                => ENV['S3_REGION']
    

    然后在我的carrier_wave.rb文件中。

    heroku config:set S3_REGION=<bucket region>
    

我还创建了一个新的存储区,新的IAM用户,并向该用户授予了AdministratorAccess权限

  1. 下一步,解决此问题后,我收到了类似...的错误

AccessDenied

在heroku日志中,我什至不知道为什么即使在为存储桶设置了所有正确的策略并向IAM用户添加完全访问权限后仍被拒绝访问,最后,我可以通过进入s3存储桶->权限->公共访问设置->编辑->然后取消选中选项...

  • 阻止新的公共ACL并上传公共对象(推荐)
  • 删除通过公共ACL授予的公共访问权限(推荐)

我知道这可以使公众访问我的存储桶,但是目前,我只有这个选项才能使它正常工作(这是一个业余项目,因此对我来说公共访问无关紧要)。

但是,如果有人提出更好的解决方案,请告诉我...
