Python Swift Examples
|
|
=====================
|
|
|
|
Create a Connection
|
|
===================
|
|
|
|
This creates a connection so that you can interact with the server:
|
|
|
|
.. code-block:: python
|
|
|
|
import cloudfiles
|
|
username = 'account_name:username'
|
|
api_key = 'your_api_key'
|
|
|
|
conn = cloudfiles.get_connection(
|
|
username=username,
|
|
api_key=api_key,
|
|
authurl='https://objects.dreamhost.com/auth',
|
|
)
|
|
|
|
|
|
Create a Container
|
|
==================
|
|
|
|
This creates a new container called ``my-new-container``:
|
|
|
|
.. code-block:: python
|
|
|
|
container = conn.create_container('my-new-container')
|
|
|
|
|
|
Create an Object
|
|
================
|
|
|
|
This creates a file ``hello.txt`` from the file named ``my_hello.txt``:
|
|
|
|
.. code-block:: python
|
|
|
|
obj = container.create_object('hello.txt')
|
|
obj.content_type = 'text/plain'
|
|
obj.load_from_filename('./my_hello.txt')
|
|
|
|
|
|
List Owned Containers
|
|
=====================
|
|
|
|
This gets a list of containers that you own, and prints out the container name:
|
|
|
|
.. code-block:: python
|
|
|
|
for container in conn.get_all_containers():
|
|
print container.name
|
|
|
|
The output will look something like this::
|
|
|
|
mahbuckat1
|
|
mahbuckat2
|
|
mahbuckat3
|
|
|
|
List a Container's Content
|
|
==========================
|
|
|
|
This gets a list of objects in the container, and prints out each
|
|
object's name, the file size, and last modified date:
|
|
|
|
.. code-block:: python
|
|
|
|
for obj in container.get_objects():
|
|
print "{0}\t{1}\t{2}".format(obj.name, obj.size, obj.last_modified)
|
|
|
|
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``:
|
|
|
|
.. code-block:: python
|
|
|
|
obj = container.get_object('hello.txt')
|
|
obj.save_to_filename('./my_hello.txt')
|
|
|
|
|
|
Delete an Object
|
|
================
|
|
|
|
This deletes the object ``goodbye.txt``:
|
|
|
|
.. code-block:: python
|
|
|
|
container.delete_object('goodbye.txt')
|
|
|
|
Delete a Container
|
|
==================
|
|
|
|
.. note::
|
|
|
|
The container must be empty! Otherwise the request won't work!
|
|
|
|
.. code-block:: python
|
|
|
|
conn.delete_container(container.name)
|
|
|
