ruby-on-rails - AWS_CONTAINER_CREDENTIALS_RELATIVE_URI 不起作用

Question

我设置了 AWS_CONTAINER_CREDENTIALS_RELATIVE_URI 环境变量并尝试在 AWS S3 私有存储桶上上传图像，但我收到 403 Access Denied Error。

Excon::Error::Forbidden Expected(200) <=> Actual(403 Forbidden)

excon.error.response
  :body          => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<Error><Code>AccessDenied</Code><Message>Access Denied</Message><RequestId>82YFG8EV8S20TWCS</RequestId><HostId>+uW4/W6lOn9h3Hu/Jri6EILuW47RU5Suv7tBQT9mhoh8/JLp3hyFXlo=</HostId></Error>"
