Python Swift Examples
=====================
Create a Connection
===================
This creates a connection so that you can interact with the server:
.. code-block:: python
import swiftclient
user = 'account_name:username'
key = 'your_api_key'
conn = swiftclient.Connection(
user=user,
key=key,
authurl='https://objects.dreamhost.com/auth',
)
Create a Container
==================
This creates a new container called ``my-new-container``:
.. code-block:: python
container_name = 'my-new-container'
conn.put_container(container_name)
Create an Object
================
This creates a file ``hello.txt`` from the file named ``my_hello.txt``:
.. code-block:: python
with open('hello.txt', 'r') as hello_file:
conn.put_object(container_name, 'hello.txt',
contents= hello_file.read(),
content_type='text/plain')
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_account()[1]:
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 data in conn.get_container(container_name)[1]:
print('{0}\t{1}\t{2}'.format(data['name'], data['bytes'], data['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_tuple = conn.get_object(container_name, 'hello.txt')
with open('my_hello.txt', 'w') as my_hello:
my_hello.write(obj_tuple[1])
Delete an Object
================
This deletes the object ``hello.txt``:
.. code-block:: python
conn.delete_object(container_name, 'hello.txt')
Delete a Container
==================
.. note::
The container must be empty! Otherwise the request won't work!
.. code-block:: python
conn.delete_container(container_name)
