我正在使用回形针的

beta版（5.0.0）和
aws sdk~>2.3
。问题就像当我试图使用回形针将图像上传到s3时，它在标题中给出了上述错误。我已经准备好了，我觉得没用。请帮助我，我被困在这大约2天。提前谢谢你
 您引用的博文是为2.0版之前的AWS SDK编写的。由于您使用的是gem'aws sdk'，'~>2.2'，'>=2.2.35'，因此需要定义区域

所以不是

Paperclip::Attachment.default_options[:s3_host_name] = 's3-us-west-2.amazonaws.com'

你会用

Paperclip::Attachment.default_options[:s3_region] = 'us-west-2'

请务必参考回形针文档，因为它从今天起是最新的。
请将bucket移出s3\u凭据，我们需要s3\u主机名才能从Amazon s3访问文档

config.paperclip_defaults = {
  storage: :s3,
  s3_region: ENV['AWS_REGION'],
  s3_host_name: ENV['AWS_HOST_NAME'],
  bucket: ENV['S3_BUCKET_NAME']
  s3_credentials: {
    access_key_id: ENV['AWS_ACCESS_KEY_ID'],
    secret_access_key: ENV['AWS_SECRET_ACCESS_KEY']
  }
}

还要确保您的IAM用户具有正确的S3权限，并且您正在为S3\u区域使用正确的值

您可以在以下链接中找到所有S3区域的列表

我已恢复到
gem'aws sdk'，“~>1.66.0”
。你能帮我解决这个错误吗（拒绝访问

您设置了AWS访问密钥Id和AWS秘密访问密钥吗？您可以在AWS文档中找到更多信息：ENV变量有问题。.谢谢！很高兴听到！请将我的回答标记为正确，以帮助其他人。很高兴我能帮上忙！我也有同样的问题。设置区域并删除和删除主机名字对我没有任何帮助。

Paperclip::Attachment.default_options[:s3_region] = 'us-west-2'

config.paperclip_defaults = {
  storage: :s3,
  s3_region: ENV['AWS_REGION'],
  s3_host_name: ENV['AWS_HOST_NAME'],
  bucket: ENV['S3_BUCKET_NAME']
  s3_credentials: {
    access_key_id: ENV['AWS_ACCESS_KEY_ID'],
    secret_access_key: ENV['AWS_SECRET_ACCESS_KEY']
  }
