Interact with SoftLayer Object Storage
Using the fog-softlayer gem to list, upload, remove and interact with Object Storage objects and containers.

Create a connection to SoftLayer Object Storage

require 'fog/softlayer'
@sl = Fog::Storage[:softlayer]

Use the Models

List directories/containers.

dirs = @sl.directories
dirs.size # the number of directories      

Create a directory/container.

@sl.directories.create(:key => 'a-container')

Get a directory/container

dir = @sl.directories.get('a-container')
dir.key  # => 'a-container'

Create a new file/object

dir = @sl.directories.get('a-container')
# Pass a string.
dir.files.create(:key => 'data.txt', :body => 'The quick brown fox jumps over the lazy dog.')
# From a file.
dir.files.create(:key => 'file-data.txt', :body => File.open('/path/to/file-data.txt')

Retrieve an existing file/object

dir = @sl.directories.get('a-container')
file = dir.files.get('data.txt')
file.body # => 'The quick brown fox jumps over the lazy dog.'

Copy a file/object

file  = @sl.directories.get('a-container').files.get('data.txt')
copy = file.copy('a-container', 'copy-of-data.txt')
copy.body # => 'The quick brown fox jumps over the lazy dog.'

List the files in a directory/container

@sl.directories.get('a-container').files
# => [
#    <Fog::Storage::Softlayer::File
#  key="a-container/data.txt",
#  content_length=43,
#  content_type="text/plain",
#  content_disposition=nil,
#  etag="a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1",
#  last_modified=1970-00-00 00:00:00 -0000,
#  access_control_allow_origin=nil,
#  origin=nil
# ...

Get a signed [temporary] url for a file/object

### NOTE
## Be sure you have set a meta_temp_url_key for your account at least once before
## @sl.post_set_meta_temp_url_key('someSortaSecretStuffHere')
### /NOTE

file = @sl.directories.get('a-container').files.get('data.txt')
file.url(Time.now + 300) # url expires in 5 minutes
# => "https://dal05.objectstorage.softlayer.net:443/v1/AUTH_1a1a1a1a-1a1a-1a1a-1a1a-1a1a1a1a1a1a/a-container/data.txt?temp_url_sig=1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a&temp_url_expires=1401901023"

Delete files/objects from a directory/container.

dir = @sl.directories('a-container')
dir.files.get('data.txt').destroy
dir.files.get('file-data.txt').destroy
dir.files.get('copy-of-data.txt').destroy
# Must destroy all files/objects before destroying container.
dir.destroy
