Amazon S3：使用aws-sdk-ruby设置权限

Question

I'm getting Access Denied for a new images path in S3. This in the same bucket, that I have worked with and for other images everything is fine. Can it be a permissions issue? If so, how can I get (and set) permissions using aws-sdk-ruby ?

The documentation has poor examples and I don't have access to amazon dashboard.

Can I do these manipulations through the gem anyway?

Answer 1

From their docs @ aws-sdk doc
als you may want to reference the bucket doc

S3 supports a number of canned ACLs for buckets and objects. These include:

:private
:public_read
:public_read_write
:authenticated_read
:bucket_owner_read (object-only)
:bucket_owner_full_control (object-only)
:log_delivery_write (bucket-only)

Here is an example of providing a canned ACL to a bucket:

s3.buckets['bucket-name'].acl = :public_read

Answer 2

The syntax has changed on

gem 'aws-sdk', '~> 2'

It is now with round brackets, instead of square. and in singular

s3.bucket(object) 

instead of

s3.buckets[object]

Full-Example :

s3 = Aws::S3::Resource.new
source = s3.bucket('bucket-name').object('some/path/filename.txt')
destination = s3.bucket('same-or-other-bucket').object('destination/filename2.txt')

copy_to(destination, acl:'public-read')
