怎么办“s3cmd LS S3：// some_bucket /富/栏”等值的红宝石？ [英] How to do the equivalent of 's3cmd ls s3://some_bucket/foo/bar' in Ruby?

问题描述

我要如何做相当于's3cmd LS S3：// some_bucket /富/酒吧？在Ruby中

How do I do the equivalent of 's3cmd ls s3://some_bucket/foo/bar' in Ruby?

我发现亚马逊S3宝石的红宝石，也是正确的AWS S3库，但不知何故，这不是显而易见如何在S3'文件夹'如位置做一个简单的'ls'的命令一样。

I found the Amazon S3 gem for Ruby and also the Right AWS S3 library, but somehow it's not immediately obvious how to do a simple 'ls' like command on an S3 'folder' like location.

推荐答案

该负责人Ruby的AWS SDK现在支持这一点：的 http://docs.aws.amazon.com/AWSRubySDK/latest/AWS/S3/Tree.html

The official Ruby AWS SDK now supports this: http://docs.aws.amazon.com/AWSRubySDK/latest/AWS/S3/Tree.html

您还可以添加以下的简便方法：

You can also add the following convenience method:

class AWS::S3::Bucket
  def ls(path)
    as_tree(:prefix => path).children.select(&:branch?).map(&:prefix)
  end
end

然后，使用这样的：

Then use it like this:

mybucket.ls 'foo/bar' # => ["/foo/bar/dir1/", "/foo/bar/dir2/"]
