taxii2-client 2.2.2

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. 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:

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.

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

• alias (2.1 only)

• can_write

• can_read

• media_types

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.
