txu1

txu1

Twisted-based async interface for Ubuntu One <https://one.ubuntu.com>_ Files Cloud REST API v1 <https://one.ubuntu.com/developer/files/store_files/cloud>_.

• U1 API docs <https://one.ubuntu.com/developer/files/store_files/cloud>_
• U1 API Auth docs <https://one.ubuntu.com/developer/account_admin/auth/index>_

Implemented from scratch on top of Twisted and oauth2 <https://pypi.python.org/pypi/oauth2/>_ (name might be confusing - it's actually OAuth 1.0 helper), does not require any ubuntu-specific libs, daemons or modules.

Usage Example

Note that email/password credentials are only needed to get the OAuth 1.0 consumer/token (which can be revoked through ubuntu single sign on interface <https://login.ubuntu.com/+applications>) once, see docs <https://one.ubuntu.com/developer/account_admin/auth/otherplatforms> for more details.

Included "u1-cli" script can also be used to generate these OAuth credentials for the apps.

Installation

It's a regular package for Python 2.7 (not 3.X).

Using pip <http://pip-installer.org/>_ is the best way:

::

% pip install txu1

If you don't have it, use:

::

% easy_install pip
% pip install txu1

Alternatively (see also <http://www.pip-installer.org/en/latest/installing.html>_):

::

% curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python
% pip install txu1

Or, if you absolutely must:

::

% easy_install txu1

But, you really shouldn't do that.

Current-git version can be installed like this:

::

% pip install 'git+https://github.com/mk-fg/txu1.git#egg=txu1'

Note that to install stuff in system-wide PATH and site-packages, elevated privileges are often required. Use "install --user", ~/.pydistutils.cfg <http://docs.python.org/install/index.html#distutils-configuration-files>_ or virtualenv <http://pypi.python.org/pypi/virtualenv>_ to do unprivileged installs into custom paths.

Requirements

-  `Python 2.7 (not 3.X) <http://python.org>`_

-  `Twisted <http://twistedmatrix.com>`_ (core, web, at least 12.2.0)

-  `oauth2 <https://pypi.python.org/pypi/oauth2/>`_
