NOTE: This is an `OASIS TC Open Repository
<https://www.oasis-open.org/resources/open-repositories/>`_. See the
`Governance`_ section for more information.

cti-taxii-client is a minimal implementation of client for the TAXII 2.0 server.
It supports the following TAXII 2.0 API services:

- Server Discovery
- Get API Root Information
- Get Status
- Get Collections
- Get a Collection
- Get Objects
- Add Objects
- Get an Object
- Get Object Manifests

Installation
============

The easiest way to install the TAXII client is with pip::

$ pip install taxii2-client


Usage
=====

The TAXII client is intended to be used as a Python library. There are no
command line clients at this time.

``taxii2-client`` provides four classes:

- ``Server``
- ``ApiRoot``
- ``Collection``
- ``Status``

Each can be instantiated by passing a `url`, and (optional) `user` and
`password` arguments. The authorization information is stored in the instance,
so it need not be supplied explicitly when requesting services.

.. code:: python

from taxii2client import Server
server = Server('https://example.com/taxii/', user='user_id', password='user_password')

Once you have instantiated a ``Server`` object, you can get all metadata about
its contents via its properties:

.. code:: python

print(server.title)

This will lazily load and cache the server's information in the instance:

- ``api_roots``
- ``title``
- ``description``
- ``default`` (i.e. the default API root)
- ``contact``

You can follow references to ``ApiRoot`` objects,
``Collection`` objects, and (STIX) objects in those collections.

.. code:: python

api_root = server.api_roots[0]
collection = api_root.collections[0]
collection.add_objects(stix_bundle)

Each ``ApiRoot`` has attributes corresponding to its meta data

- ``title``
- ``description``
- ``max_content_length``
- ``collections``

Each ``Collection`` has attributes corresponding to its meta data:

- ``id``
- ``title``
- ``description``
- ``can_write``
- ``can_read``
- ``media_types``

A ``Collection`` can also be instantiated directly:

.. code:: python

from taxii2client import Collection
collection = Collection('https://example.com/api1/collections/91a7b528-80eb-42ed-a74d-c6fbd5a26116')
collection.get_object('indicator--252c7c11-daf2-42bd-843b-be65edca9f61')

In addition to the object-specific properties and methods, all classes have a
``refresh()`` method that reloads the URL corresponding to that resource, to
ensure properties have the most up-to-date values.
