TAXII 2 Client Library
NOTE: This is an OASIS TC Open Repository. See the Governance section for more information.
cti-taxii-client is a minimal client implementation for the TAXII 2.X server. It supports the following TAXII 2.X API services:
Get API Root Information
Get a Collection
Get an Object
Delete an Object (2.1 only)
Get Object Manifests
Get Object Versions (2.1 only)
The easiest way to install the TAXII client is with pip
$ pip install taxii2-client
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:
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. By default, the latest version of the supported spec will be imported. If you need a specific version you can perform the following:
from taxii2client.v21 import Server server = Server('https://example.com/taxii2/', user='user_id', password='user_password')
Once you have instantiated a Server object, you can get all metadata about its contents via its properties:
This will lazily load and cache the server’s information in the instance:
default (i.e. the default API root)
You can follow references to ApiRoot objects, Collection objects, and (STIX) objects in those collections.
api_root = server.api_roots collection = api_root.collections collection.add_objects(stix_bundle)
Each ApiRoot has attributes corresponding to its meta data
Each Collection has attributes corresponding to its meta data:
alias (2.1 only)
A Collection can also be instantiated directly:
# Performing TAXII 2.0 Requests from taxii2client.v20 import Collection, as_pages collection = Collection('https://example.com/api1/collections/91a7b528-80eb-42ed-a74d-c6fbd5a26116') collection.get_object('indicator--252c7c11-daf2-42bd-843b-be65edca9f61') # For normal (no pagination) requests collection.get_objects() collection.get_manifest() # For pagination requests. for bundle in as_pages(collection.get_objects, per_request=50): print(bundle) for manifest_resource in as_pages(collection.get_manifest, per_request=50): print(manifest_resource) # ---------------------------------------------------------------- # # Performing TAXII 2.1 Requests from taxii2client.v21 import Collection collection = Collection('https://example.com/api1/collections/91a7b528-80eb-42ed-a74d-c6fbd5a26116') collection.get_object('indicator--252c7c11-daf2-42bd-843b-be65edca9f61') # For normal (no pagination) requests collection.get_objects() collection.get_manifest() # For pagination requests. envelope = collection.get_objects(limit=50) while envelope.get("more", False): envelope = collection.get_objects(limit=50, next=envelope.get("next", "")) envelope = collection.get_manifest(limit=50) while envelope.get("more", False): envelope = collection.get_manifest(limit=50, next=envelope.get("next", ""))
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.
