Ruby Swift Examples

Create a Connection

This creates a connection so that you can interact with the server:

require 'cloudfiles'
username = 'account_name:user_name'
api_key  = 'your_secret_key'
conn = CloudFiles::Connection.new(
        :username => username,
        :api_key  => api_key,
        :auth_url => 'http://objects.dreamhost.com/auth'
)

Create a Container

This creates a new container called my-new-container

container = conn.create_container('my-new-container')

Create an Object

This creates a file hello.txt from the file named my_hello.txt

obj = container.create_object('hello.txt')
obj.load_from_filename('./my_hello.txt')
obj.content_type = 'text/plain'

List Owned Containers

This gets a list of Containers that you own, and also prints out the container name:

conn.containers.each do |container|
        puts container
end

The output will look something like this:

mahbuckat1
mahbuckat2
mahbuckat3

List a Container’s Contents

This gets a list of objects in the container, and prints out each object’s name, the file size, and last modified date:

require 'date'  # not necessary in the next version
container.objects_detail.each do |name, data|
        puts "#{name}\t#{data[:bytes]}\t#{data[:last_modified]}"
end

The output will look something like this:

myphoto1.jpg 251262  2011-08-08T21:35:48.000Z
myphoto2.jpg 262518  2011-08-08T21:38:01.000Z

Retrieve an Object

This downloads the object hello.txt and saves it in ./my_hello.txt:

obj = container.object('hello.txt')
obj.save_to_filename('./my_hello.txt')

Delete an Object

This deletes the object goodbye.txt:

container.delete_object('goodbye.txt')

Delete a Container

Note

The container must be empty! Otherwise the request won’t work!

container.delete_container('my-new-container')
