我刚刚在 Heroku 上托管的 Rails 应用程序中实现了回形针。该应用程序似乎连接并将图像上传到 s3。以下是我在应用程序上提交表单时的一些日志示例：

我上传的图像出现在我的 S3 存储桶控制台中。

我的视图用于@illustration.image.url获取要显示的图像。

我没有在任何地方为图像设置权限。它们是否会自动为应用程序正确设置以上传和下载图像？

谢谢。

首先，您必须在s3 存储桶中将所有图像设置为公开。如果图像默认设置为私有。如果图像是私有的，您将无法看到图像。

其次，设置您的 s3 存储桶的所有凭据。

在 **config/s3.yml 文件中将 s3 凭证设置为

development:
 access_key_id: your_access_key_id
 secret_access_key: your_access_key
 bucket: your_bucket_name
production:
 access_key_id: your_access_key_id
 secret_access_key: your_access_key
 bucket: your_bucket_name

然后在config/initializers/s3.rb文件中将所有图像初始化为

if Rails.env == "production"
 # set credentials from ENV hash
 S3_CREDENTIALS = { :access_key_id => ENV['access_key_id'], :secret_access_key => ENV['secret_key'], :bucket => "bucket_name"}
else
 # get credentials from YML file
 S3_CREDENTIALS = Rails.root.join("config/s3.yml")
end
